Introduction 1.4.

ONEPROD NEST ANALYST is a multi-technique information System devoted to predictive maintenance and allowing for the acquisition of vibration, process, oil or thermographic measurements in order to identify or predict the occurrence of problems on a wide variety of industrial rotating machines. The aims of such software are:

Avoid unexpected equipment breakdowns

Plan shutdowns

Decrease maintenance and repair costs

For many years now, our Service Department has performed numerous expert evaluations and is in charge of the maintenance of hundreds of machines in various domains of activity, such as the automotive industry, energy, and paper mills. The primary specification around which ONEPROD NEST ANALYST was developed was to meet the requirements of our field engineers and operators. ONEPROD NEST ANALYST is a new generation maintenance System. As such, it includes a self-diagnosis module based on alarms (OK, ALARM, DANGER) resulting from the monitoring of several parameters. Each parameter gives information on the equipment status, resulting in a global diagnosis of the equipment each time a control is performed and thus helping the operator to issue the final diagnosis. Given the strategic importance of internal corporate communication, ONEPROD NEST ANALYST offers a complete range of tools to access, analyse and circulate maintenance information to all interested persons in the company: web/intranet access, reporting, email, etc.

GENERAL POINTS 2.

Domain of application 2.1.

ONEPROD NEST ANALYST has been designed to implement, on a set of industrial rotating machines, offline (periodical) and online (permanent) monitoring of parameters that are characteristic of status or mechanical behaviour. These parameters are measured using the main techniques of non-destructive control currently used in industry and maintenance departments: vibrations, oil, process, temperature, etc. ONEPROD NEST ANALYST covers a wide range of applications since it meets the technical and technological requirements of mechanical equipment making up various industrial production tools, and used in chemistry, petrochemistry, paper-making industry, energy production, food industry, transportation, etc. ONEPROD NEST ANALYST can communicate. It can therefore share data with other software tools (spreadsheet, word processors, etc.), with other sections of the plant (production, management, etc.) and with other companies (oil analysis laboratories, 01dB-Metravib e-maintenance and e-diagnosis, external service provider, etc.). ONEPROD NEST ANALYST is an industrial tool for measurement, analysis and assistance in decision making. It is made up of a set of modules allowing to program (online, offline) data acquisition Systems and to issue a behavioural diagnosis based on graphic display and signal processing tools. It provides the user with simple and synthetic information that will be helpful to make the appropriate decision in due time.

Operating modes 2.2.

ONEPROD NEST ANALYST can be installed:

On a single work station

On a client/server architecture Due to its new generation software architecture, ONEPROD NEST ANALYST is compatible with the Web and offers new operating ways allowing the user to be totally independent from computing requirements:

Rental of “ONEPROD NEST ANALYST Service” – The user belongs to a small structure that does not include a computer department. He/she needs assistance in his/her maintenance policy and considers the maintenance tool as a service.

Installation on the company’s Intranet – The users belong to a user group that needs to share the same maintenance tool and record their experience. This tool is shared on the corporate network and accessible to all. Users focus on their tasks, while the computer System management is taken care of by the computer department.

The type of installation is defined depending on your purposes and operating means. In any event, the System will be suited to your working environment.

Safety and traceability 2.3.

A many-level safety of operations is guaranteed by ONEPROD NEST ANALYST:

Data securisation o Oracle database engine, recognised as the leading product on the market o Relational database including activity-specific management rules o Data warehousing within the database: measurements, reports, images, etc.

Access securisation o Management of user accounts using user ID and password o Management of user profiles allowing to restrict access to some functions

TERMINOLOGIES & CONCEPTS 4.

Application terminology 4.1.

Introduction 4.1.1.

Using ONEPROD NEST ANALYST on a daily basis requires that the following terminologies and concepts be known and understood:

Equipment o Equipment/Location

Measurement point

Parameter/signal & Alarm

Libraries o Model measurement point o Model parameter/signal

Control o Control date o History

Equipment 4.1.2.

Before setting up the monitoring of a set of equipment, ONEPROD NEST ANALYST can be used to define, as a tree structure, all pieces of equipment and to sort them according to different locations.

Two concepts are used: “location”: to represent a geographic point or a functional element: workshop, production line, building, group of complex machines… “equipment”: to represent a piece of equipment under monitoring and on which measurements and operating status are defined. In order to simplify operations, each piece of equipment can be freely assigned to any location. Similarly, a location can itself belong to another location.

The tree structure thus described provides an overall and schematic view of all machines according to their geographic or functional location.

Measurement points, parameters, signals and alarms 4.1.3.

Once the equipment tree structure has been described, the monitoring should be defined for each piece of equipment. To do so, ONEPROD NEST ANALYST uses the concepts of measurement points, parameters and signals. Programming these entities is called “equipment set-up”. Monitoring a piece of equipment consists in:

Programming operating parameters

Programming monitoring parameters

Defining alarms for each parameter

Measuring signals and parameters (hard parameters and signals)

Calculating signals and parameters (soft parameters and signals)

Elaborating alarm statuses for parameters

Deducting and display the operating status for the equipment

22

Brand of ACOEM

For each piece of location or equipment, the current alarm status is displayed in the tree structure according to the following code:

DANGER At least one item is in DANGER

ALARM At least one item is in ALARM

PRE-ALARM At least one item is in PRE-ALARM

OK All items are OK.

UNKNOWN No item has been either measured or calculated.

This alarm status is always worked out from the most recent measurements performed on the equipment.

Concept of “Model Libraries” 4.1.4.

In order to speed up the equipment set-up phase, ONEPROD NEST ANALYST manages model libraries used to provide at once all parameters required for the monitoring of a given machine. Different libraries are available:

Model signals: pre-programmed signals (spectrum, time spectrum, envelope spectrum, etc.), associated with no measurement point, and that can be used to set up the monitoring of any piece of equipment.

Model parameters: pre-programmed monitoring parameters (overall level, unbalance, bearing defect, etc.), associated with no measurement point, and that can be used to set up the monitoring of any piece of equipment.

Model measurement points: pre-programmed measurement points, not associated with any equipment and containing model signals and parameters. These model points are selected when setting up a piece of equipment and allow for an automatic programming of the monitoring.

Bearing reference: list of manufacturers and types of bearings allowing selecting the bearing characteristics of each piece of equipment among about 40,000 references.

Equipment tree structure:

Locations and equipment

Current equipment

List of measurement points for current equipment…

List of parameters for current measurement point…

List of signals for current measurement point…

List of operating parameters for current equipment…

23

Brand of ACOEM

Monitoring locations: identify preferred areas on each piece of equipment, e.g., bearing on opposite side of coupling, coupling-side bearing, etc. Bearing references characteristic of a machine are defined by monitoring location.

Pre-programmed notes: the list is uploaded into the collector with each route. The collector allows assigning to each measurement point an inspection note created either from this list or by direct input from the instrument keyboard. Upon download, inspection notes are stored in the database. They are available from the “Control information” window and in the reports.

These libraries are defined when installing the application and can be complemented by the user.

Measurement control and history 4.1.5.

Several control techniques may be required to monitor a piece of equipment: VIBRATION Acquisition Systems (MVP-200, Movipack, Movilog2, MVX … ) ELECTRIC Acquisition Systems MVX OIL Analysis laboratories (PALL, KITTIWAKE, …) PROCESS Acquisition System (MVP-200, Movipack, Movilog2, MVX … ) THERMOGRAPHY Images from Thermal camera With each control, the ONEPROD NEST ANALYST database becomes richer with new measurements, which allows determining the new operating status for the equipment. Measurements are viewed through a specific interface in which the date and time of each one are listed.

This interface displays the control date for each technique as chronological lists (history concept). Each monitoring technique has its own history, which is accessible by selecting the corresponding tab:

Most recent measurement

Oldest measurement

Using the “Equipment” tree structure 4.3.2.

4.3.2.1. Type of node

A location can contain:

a set of “sub-locations”

a set of equipment A “location” node can be either “open” or “closed”:

A node is opened/closed by double clicking on the node or by a single click on or . An “equipment” node is always located at the end of a branch. It does not contain any sub-element in the tree:

Tool bar functions:

: fully open current location and sub-locations.

: fully close current location and sub-locations.

“Location” nodes

“Equipment” nodes

26

Brand of ACOEM

4.3.2.2. “Current node” concept

To move through the “equipment” tree structure, use the left button of the mouse. To view information associated with a piece of equipment, just look for the corresponding equipment in the tree structure, place the mouse on the equipment and click once.

Each mouse click will highlight the current node in black:

When browsing the tree structure, all application windows are automatically refreshed in order to display the information (“Setup” or “Monitoring” modules) corresponding to the current element.

4.3.2.3. Multiple node selection

“Equipment” or “location” nodes can be selected using the CTRL key while clicking on the mouse (like in Windows’ Explorer). Selected nodes are highlighted in black:

In the above example, “Moteur P104 dem.”, “Pompe P104 dem.” and “Pompe T1” have been selected. In case of a multiple selection, the current element is always the element selected last. Consecutive elements can be selected using the SHIFT key.

Information list 4.3.3.

4.3.3.1. Definition

An information list is used to display, as a table, a set of records corresponding to the same type of information. Examples:

List of measurement points

List of signals

List of parameters

… All lists have the same characteristics:

a title identifying the type of information

a multi-line zone displaying (in table format) several elements, each representing a record (e.g., measurement point, parameter, etc.)

a scrollbar used to browse through the list

A “Sel.” column used to check elements in the list

Title

Multi-line zone

Scroll bar

Selection column

28

Brand of ACOEM

4.3.3.2. “Current element” concept

Each information list contains a current element, which is highlighted in dark blue. This current element corresponds to the last selected element, either by a single click or by using the arrow keys.

The properties corresponding to the current element can be edited by double clicking on the element or by activating the “Properties” function available from the context menu of the list.

4.3.3.3. Multiple selection of elements

Elements in an information list can be selected by checking the corresponding box in the “Sel.” column.

This selection can be performed manually element by element or automatically using the “Select All/No element(s)” function in the context menu. In the above example, “1 Ro”, “2 Ro” and “3 Ro” measurement points are selected.

Context menus 4.3.4.

4.3.4.1. Principle

The information lists and the “equipment” tree structure have context menus that allow for immediate access to management functions.

Current element

29

Brand of ACOEM

To access context menus, place the mouse on the element, list or tree, and press the right button. The menu is then displayed and lists all available functions. Examples of context menus:

Group functions 4.3.5.

Functions called “group functions” are functions that are applied to a selection of elements (tree or list). Group functions are identified by their labelling: “… selected element(s)”.

Example for “measurement points”: In the example below, “1 Ro”, “2 Ro” and “3 Ro” measurement points will be deleted.

Generic functions 4.3.6.

Context menus include the following functions: “New”: create a new record. “New from models”: create new records from a list of pre-programmed models (see Libraries). “Properties”: edit the record corresponding to the current element in the list. This function can be accessed either from the context menu, or by double clicking (left button) on the said element.

30

Brand of ACOEM

“Select All/No element(s)”: select all (or none) elements on the list to apply a group function to the selection. “Delete selected element(s)”: delete selected element(s). “Regenerate order number”: regenerate the “order number” values for each record in the list (see References). “First element”: go to the first element on the list. “Previous element”: go to the element previous element (with respect to the current element). “Next element”: go to the next element (with respect to the current element). “Last element”: go to the last element on the list.

Generic interfaces 4.3.7.

In order to give a lighter aspect to the screens, most action buttons are managed as mouse-sensitive interactive images. Remark: in web versions buttons are not sensitive. As a general rule, the following icons are used:

– Refresh information

– Validate

– Cancel or delete current element

– Put element in the trash

– Close module

– Access set-up parameters

Setting up the monitoring of the first piece of equipment 5.5.

Principle 5.5.1.

Setting up a piece of equipment consists in defining the following elements: Operating parameters: each piece of equipment contains at least one rotation speed parameter. This parameter can be fixed or variable. It is used by peak extraction processings to extract amplitudes relative to the machine kinetics. In On-line mode, this rotation speed, as well as 5 other parameters, can be used to characterise the operating condition of the machine. These 5 parameters can be:

2 process parameters (flow, pressure, loads, …) measured from DC inputs

3 logical parameters (On/Off, Open/Closed, …) measured from logical inputs. Measurement points: Geographic point on the equipment where vibration, oil process or thermographic measurements are physically collected. The measurement point can usually be assimilated to a sensor or more generally speaking to a data source. Monitoring locations: Geographic area on the equipment containing several measurement points and allowing associating a set of bearing references to a set of measurement points. These bearing references are then used during data processing. Signals: For each measurement point, signals define vector-type data (e.g., a curve) required to monitor the equipment. A specific processing (spectra, envelopes, zoom, time spectra) corresponds to each signal indicating the way the signal was obtained. Some signals called “hard” result from an acquisition (collector, etc.), while other signals called “soft” result from the post-processing of hard signals. Monitoring Parameters: For each measurement point, parameters define scalar-type data (e.g., an overall level) required to monitor the equipment. To each parameter corresponds a specific processing (overall level, peak extraction, energy level, Kurtosis, etc.) indicating the way the parameter was obtained. Some parameters called “hard” result from an acquisition, these are overall levels. Other parameters, called “soft”, result from the post-processing of hard and/or soft signals. Alarm: In order to monitor a parameter over the successive controls (measured or calculated values), alarm criteria can be associated with each parameter. The parameter alarm status thus obtained is used to determine the alarm status of the measurement point, which in turn, will be used to determine the alarm status of the equipment. Off-line Data collection route for ONEPROD MVP: Once all measurement points are defined, ONEPROD NEST ANALYST is all set to start monitoring the equipment. Collection routes are required to perform an “off line” monitoring. These routes correspond to equipment selections that are loaded into the data collectors. They are then collected by the roundsmen, and downloaded into ONEPROD NEST ANALYST. The history of each piece of equipment is then updated with the new measurements. Parameters and alarm statuses are worked out and used to determine the current operating status of each piece of equipment. On-line acquisition for ONEPROD MVX: for on-line Systems, additional configuration is required:

Definition of the on-line System and its measurement channels

Association of each point of the machine with measurement channels

If required, definition of the different operating conditions of the machine

Definition of cases and periodicities of automatic acquisition.

Step #1: Creating the 1st measurement point 5.5.2.

To set up the new equipment ‘‘M.P104’’, first go to the Configuration mode by checking the corresponding box in the ONEPROD NEST ANALYST toolbar:

The rotation speed must be defined first. Select whether the speed is fixed or variable:

Fixed speed: the defined value will be automatically assigned to each new measurement. To change it, display the properties of this parameter (right click / Properties or double click)

You can then change the label, the value and the unit (Hz or RPM) of the rotation speed.

Variable speed: selecting ”Variable speed” will automatically open the Properties window, which allows to define the acquisition parameters of the rotation speed:

38

Brand of ACOEM

This rotation speed is used by the peak extraction processing to extract amplitudes relative to the machine kinetics. There are 3 measurement points on this piece of equipment:

RADIAL NDE: a measurement point located on Bearing 1 in the radial direction,

AXIAL NDE: a measurement point located on Bearing 1 in the axial direction,

RADIAL DE: a measurement point located on Bearing 2 in the radial direction.

To create a measurement point, place the cursor on the list of measurement points, right click and select “New”:

39

Brand of ACOEM

The “Measurement point properties” window is displayed. Creation of a new point: “RADIAL NDE”:

Notes: Multiplier/reducer coefficient: This coefficient is input as a N1/N2 ratio, which allows for direct input in N1 and N2 of the numbers of gear teeth (or pulley diameters) of a multiplier/reducer stage. The rotation speed taken into account at the measurement point is machine rotation speed x (N1/N2) Speeds of each point are available in the “Measurement information” window (“Constants” tab): see § 5.13 Note: when using ONEPROD MVX, N1 and N2 must be integers ranging from 1 to 65535. Two-channel measurements: this function requires the use of a ONEPROD MVP (Movipack) data collector with the “2

nd channel” option along with version V4.2 or higher of the firmware.

o Points can be associated in two ways: Association with a “New point”: in this case, a new point, identical to the current point,

is created. The current point is called the “master” point, while the newly created point is called the “slave” point.

Association with an existing point: only compatible points are available:

same name

same measurements The current point is the “master” point, while the associated point is the “slave” point.

Brand of ACOEM

o After association: Points are listed on screen in the “Monitoring definition” screen: the first point is

the master point ( ), then comes the slave point ( ). Point names cannot be changed.

Changes to the master point measurements are automatically applied to the slave point.

Only sensitivity and alarm thresholds can be changed for the slave point. o Upon upload, ONEPROD NEST ANALYST automatically detects whether the collector is

in single or dual channel mode. On a 2-channel collector, a « point association » is considered as a 2-channel

measurement point, master point on channel 1 and slave point on channel 2. On a 1-channel collector, a « point association » is uploaded as 2 measurement

points, master point first and then slave point. o Reminder on the limits of ONEPROD MVP Collector, 2-channel mode:

Measurements are identical on both channels

Spectra are limited to 6400 lines

Time spectra are limited to 16 K samples without the DAT option and 256 K samples with the DAT option

Cross functions are not available in the “collector” module for spectra measured in 2-channel mode. Note: cross functions are available in the “analyser” module.

Envelope and zoom spectra are not available in 2-channel mode.

Defect Factor and Kurtosis measurements are not available in 2-channel mode.

Overall vibration level measurements are limited to a maximum analysis frequency of 20 kHz.

Once all the properties of the measurement points have been defined, validate by closing the window. The new point is displayed in the list of measurement points and becomes the current element in the information list.

“Signals” and “parameters” now need to be assigned to this measurement point. Remark: it is also possible to modify directly the contents of “Abbrev.”, “Name”, “N1”, “N2”, “Location”,

Direction” and “Orientation” columns in the “Measurement points” window. Click on to validate

modifications or to cancel them.

Step #2: Creating signals 5.5.3.

A measurement point can contain several signals of different types: simple spectrum, envelope spectrum, time signal, etc. To add a signal to the current measurement point, click on the signal list, and then right click to display the context menu. Select “New > …” to gain access to all types that can be created. Let us choose “Simple spectrum”:

Once the type of signal is selected, the properties window is displayed and can be used to enter the identification and programming information for the new signal:

Signal identification

Signal programming arguments. They define how the signal is obtained: Fmin, Fmax, Sampling Freq., etc.

Type of signal: Hard / Soft Acquisition mode: Online/Offline Category: Vibration / Process / Oil / Other This information defines how the signal is taken into account under operating conditions (upload, processing, etc.).

Standard: access to main characteristics Advanced & Full: access to more complete characteristics

Order of measurement

42

Brand of ACOEM

Signal programming arguments can be either directly entered (white field) or selected among a list of values (grey field). The list of values can be edited by double clicking on the field:

Each type of signal has its own specific list of programming arguments. The list of arguments for each processing is provided in the Appendix 3 of this manual (See § 14). A measurement point can contain any number of signals. The only limitation is that of the data collector, which, depending on the model, will only be able to handle a restricted number of hard signals. For our example (programming the “RADIAL COA”), we will create:

3 simple spectra “hard”

1 envelope spectrum “hard”

1 raw acquisition time signal “hard”

3 post-processed filtered time signals “soft”

“Soft” signals are used to work out complex signals through post-processing of existing signals. In the above example 3 “soft” signals are defined that allow to (band-pass) filter the “Tps – 51.2 kHz – 8192” “hard” time signal over 3 filtering bands. Note: All parameters and signals available in ONEPROD NEST ANALYST are described in the Appendix (see § 14)

43

Brand of ACOEM

Step #3: Creating parameters 5.5.4.

In order to issue a diagnosis for the equipment, it is necessary to define monitoring parameters on which the analysis will be based. As previously explained these parameters may either be soft or hard. Hard parameters originate from an acquisition, whereas soft parameters are computed by post processing. These post-processing calculations are applied, either to a combination of other parameters (sum, statistics, etc.), or directly on the measurement point signals (peak extraction, Kurtosis, etc.). To add a parameter, click in the parameters list, then right click to display the context menu and select “New > …”.

Once the type of processing has been selected, the properties window is displayed and information on identification and programming of the new parameter can be entered:

Like for signal programming, parameter programming arguments can be either directly entered (white field), or selected from a list of values (grey field).

Step #4: Definition of alarms 5.5.5.

Once the monitoring parameters are defined for the 1st measurement point, the next step consists in

entering the values and types of alarm to be assigned to these parameters. Alarms are not required for all parameters.

To do so, use button in the toolbar. This will display the “Alarm and Properties” window, select the “Absolute” or “Relative” tab to adjust corresponding thresholds of selected parameters:

The Threshold Setup window is always displayed in the foreground. To enter alarm thresholds for one parameter, click on this parameter so that the threshold setup window becomes associated with the parameter thresholds. Different types of alarm can be associated to a parameter:

Absolute alarms: Standard alarm used to know if the measured (or calculated) parameter is OK, in PRE-ALARM, in ALARM or in DANGER.

Relative alarms – Complex alarm used to assess the time history of the parameter (see appendix 4 § 15). This type of alarm only results in OK or ALARM statuses.

Evolution T-1: monitors the parameter with respect to the previous control.

Reference: monitors the parameter history with respect to the value obtained at a reference date.

Statistical: monitors the parameter history with respect to its average value since a reference date.

Predictive: extrapolates the current parameter history and issues an alarm if the parameter is likely to switch to alarm mode before the date of the next control.

The alarm status that will be taken into account for this parameter will be the most penalising combination of all these elementary alarms.

ALARM if AL+ ≤ value < DG+

PRE-ALARM if pAL+ ≤ value < AL+

NORMAL if Err < value < pAL+

ERROR if value ≤ Err

“Low”

ERROR if Err ≤ value

NORMAL pAL- < value < Err

PRE-ALARM if AL- < value ≤ pAL-

ALARM if DG- < value ≤ AL-

DANGER if value ≤ DG-

“Outside”

DANGER if value ≥ DG+ or value ≤ DG-

ALARM if AL+ ≤ value < DG+ or DG- < value ≤ AL-

NORMAL if AL- < value < AL+

“Inside”

DANGER if DG- ≤ value ≤ DG+

ALARM if DG+ < value ≤ AL+ or DG- < value ≤ AL-

NORMAL if value > AL+ or value < AL-

47

Brand of ACOEM

Once alarms are defined for the monitoring parameters, the setup of the “RADIAL NDE” measurement is completed. Hysteresis for on-line measurements: on an on-line System used for the permanent monitoring of parameter statuses, it is possible to get many status changes when the measured level gets closer and closer to an alarm threshold. To avoid these repeated changes, it is possible to define a hysteresis threshold stabilising the alarm status. In the example opposite, the switching from alarm to danger status occurs when the level reaches 8 mm/s. If the level decreases again, since the hysteresis is 10%, the status will go back to “Alarm” at 7.2 mm/s (8 – 8x10%). Remark: hysteresis is exclusively used by ONEPROD MVX, the alarm Status displayed in ONEPROD NEST ANALYST do not take account of this parameter

Step #4 (continued): Adjustment of parameter or signal options 5.5.6.

There is a 2nd

tab in the “Quick access” window called “Properties”:

The following options are available from this window: PSS display: select this option to display the parameter or signal in the PSS or SSS view. Report display: select this option to edit the parameter in analysis and measurement reports Gauge display: select this option to transfer parameter-related frequencies to the background of

the spectrum (only for parameters of the line extraction and broadband type). Inhibited: inhibited parameters or signals are neither measured nor calculated. This way, the use

of some parameters can be stopped, while their history remains stored in the database. . Options are available to hide inhibited elements on the PSS screens and in reports to generate “lighter” reports.

Monitored: select this option to move the alarm status of the parameter up to the machine level. Options are available to hide non-monitored elements on the PSS screen and in reports.

Step #5: Automatic creation from libraries… 5.5.7.

In order to proceed with the monitoring of the new piece of equipment, one now needs to add two other measurement points:

AXIAL NDE: 1 measurement point on Bearing 1,

RADIAL DE: 1 measurement point on Bearing 2. Since the setup procedure for the 2 new points is similar to that of the first point (“RADIAL NDE”), we are going to use the “Library” concept of ONEPROD NEST ANALYST. In order to automatically reproduce the programming of the RADIAL NDE point onto the 2 new measurement points, a model measurement point needs to be created from the RADIAL NDE point. To do so:

Place the cursor on the list of measurement points,

Check the “RADIAL NDE” measurement point,

Right click to access the context menu,

Select “Add element(s) to model(s)”.

This operation automatically creates all signals and parameters associated with the “RADIAL NDE” measurement points in the ONEPROD NEST ANALYST libraries. Also, this “pre-programmed” measurement point will be added to the library of model measurement points. Once the model point has been added to the library, creating the 2 new measurement points will consist in selecting the new model measurement point and in requesting ONEPROD NEST ANALYST to create two measurement points from this model.

49

Brand of ACOEM

To do so, and starting from the list of measurement points assigned to the equipment:

Go to the list of measurement points,

Right click to access the context menu,

Select “New from models” The library of model measurement points is then displayed:

+

The “RADIAL NDE” model measurement point is listed. To create the 2 missing points:

Check the “RADIAL NDE” model point

Specify the quantity of measurement points to create from the model

Exit the library to validate There are now 2 new points in the list of measurement points for the “M.P104” equipment:

The properties of the two points thus created should be manually edited to specify the right names, abbreviations, monitoring locations, direction and orientation. Remark: it is also possible to modify directly the contents of “Abbrev.”, “Name”, “N1”, “N2”, “Location”, Direction” and “Orientation” columns in the “Measurement points” window.

Click on to validate modifications or to cancel them. When needed, the lists of signals and parameters can be modified locally at each measurement point.

The “M.P104” machine is now fully set up and ready to be monitored.

Brand of ACOEM

Duplicating a piece of equipment 5.6.

Once the monitoring of the “M.P104” motor has been performed, it is very straightforward to set up the monitoring for the pump associated with this engine. Principle:

Create a new piece of equipment, “P.P101”, at the same location as the engine

Create 2 measurement points: “RADIAL CA” and “RADIAL COA”

For each point, define the same list of signals and parameters for as “M.P104”

Specify alarms for “P.P101” monitoring parameters To do so, ONEPROD NEST ANALYST uses a powerful Copy/Paste function that allows duplicating a piece of equipment and its associated setup. This function is directly accessible from the context menu of the “Asset hierarchy” tree.

Copy… “M.P104” Paste… in “GLYCOLS” Before pasting the equipment, ONEPROD NEST ANALYST lets you choose the type of information to duplicate:

Once pasting options are specified, click on to continue or on to cancel.

“Parameters” & “Signals” options are used to duplicate all parameters and signals, respectively, programmed for each measurement point of the equipment. It is possible to unselect soft elements.

“Measurement history” is used to duplicate the measurement history for all parameters and signals of all measurements included in the selected period of time.

This new machine should then be modified to meet the expectations and monitoring criteria of a pump rather than an engine. Editing / modifying equipment properties… Its name is that of the duplicated equipment indexed with a “(+)” indicating that this equipment results from the duplication of another one. This name can be modified by editing the equipment properties and entering the new name (“P.P101” here).

Using a data collector with NEST ANALYST 5.10.

Principle 5.10.1.

We have seen that the monitoring of a piece of equipment is based on the periodical computation of operating parameters, on the assessment of their elementary alarm status (OK, ALARM, DANGER) and finally on the resulting determination of the global operating state of the equipment. We know that, for a piece of equipment, the history of operating parameters is based on the acquisition of measurements (overall levels, spectra, time signals) that are then post-processed. These measurement data can be acquired in different ways:

Periodically by “off-line acquisition” using data collectors, such as ONEPROD MVP (Movipack), Movilog2 …

Continuously by “on-line acquisition” using ONEPROD MVX Systems

Step #1: Creating a selection of equipment 5.10.2.

The basis of an off-line control relies on the route concept. This route represents one or several machines, having each points, “hard” parameters and signals to measure in order to check the good operating of each machine. A route may then contain one or several machines. The user is responsible for creating routes, which can be done directly from the “Asset hierarchy” tree. Going back to our example, where we just created “M.P1043 and “P.P101”:

57

Brand of ACOEM

To create a route, one needs to:

Select (CTRL + Click) the 2 machines “M.P1043 and “P.P101”: elements are then highlighted in black;

Right click to display the context menu of the tree and select the “Create a selection” function;

A selection manager is displayed in the foreground:

* Note: Machines appear in the order in which they have been selected. This order can be changed later using the “Order no.” column. The newly created selection is displayed on top of the list. A default name is assigned to this selection. It can be modified by double clicking on the selection to edit the Selection properties:

Once the selection is correctly renamed, the different modification must be validated and the selections manager closed to access the collection manager.

Step #2: Loading scheduled measurements into the collector 5.10.3.

We are now going to load “Route_A” into the data ONEPROD MVP (Movipack). To do so, we should:

Declare the data collector (the first time) by clearly stating its serial number. For ONEPROD MVP (Movipack), the serial number is checked before each transfer.

Select the data collector.

Select “Route_A” in the list of loadable routes

Select the communication port: COM1. Note: if Movipack is connected through the USB port, it will be detected automatically.

Connect the data collector to the specified port and set the instrument to transfer mode.

Press the “load” button

Once loaded into the collector, the route is displayed in the list of downloadable routes:

Notes:

The serial number of ONEPROD MVP (Movipack) is checked by ONEPROD NEST ANALYST upon each upload.

Several routes can be loaded at the same time by selecting these routes in the “Routes to load” list.

Each loaded route has a loading “status”:

Successful loading – GREEN – no message

Loading with warning – YELLOW – with message

Loading with error – RED – with message

Step #3: Performing measurement with the collector 5.10.4.

Once loaded into the data collector, the route must be selected and followed by the roundsman for each measurement point of the equipment under monitoring. (Refer to the user manual of the data collector)

Step #4: Transferring data from the collector to NEST ANALYST 5.10.5.

The collection of “Route_A” is now completed. Measurement data should be downloaded into ONEPROD NEST ANALYST. To do so:

Select the collector. Routes loaded onto the instrument are listed.

Add the following information if necessary:

Sensor and connector identifiers. This information is then associated to the selected collector, which avoids another input for future downloads.

Download note: Along with the operator’s name and the serial number of the collector, traceability information will be assigned to all downloaded measurements. It will be available in the “Measurement information” window, as well as in reports. It will also be complemented by inspection notes captured in the collector during the measurement session.

Select “Route_A” in the list of downloadable routes Select the communication port: COM1. This operation is not required if the transfer is performed

through the USB port.

Connect the data collector to the specified port and set it to transfer mode.

Press the “Download” button.

Notes:

Each downloaded route presents a download “status”:

Successful download – GREEN – no message

Download with warning – YELLOW – with message

Download with error – RED – with message

Several routes can be downloaded at the same time. Just select the different routes in the “routes to download” list.

61

Brand of ACOEM

When downloading a route, a new date of measurement is created for the different pieces of equipment in the route. This date will generate the following elements in the ONEPROD NEST ANALYST database:

A date by equipment and by monitoring technique. This date corresponds to the last measurement date for elements measured on the complete route.

Measurement results for hard signals and parameters

Calculation results for soft signals and parameters

Alarm status for parameters, measurement points and equipment relative to this last control. If, when downloading a route, some of the measurements could not be assigned in the production assets, they will be stored as additional measurements. This can occur if some elements of the production assets have been deleted. Important note: if there is a delay between the measurement time read on the data collector and the measurement time displayed in ONEPROD NEST ANALYST, the value of the following parameter must be increased or decreased:

o In menu “Edit / Preferences”, preference “Server application”: o For ONEPROD MVP (Movipack): Time shift for MVP (h) o For Movilog2: Time shift for Movilog2 (h)

How to use a MVX or KITE on-line System with NEST ANALYST? 5.11.

Principle 5.11.1.

With the ONEPROD MVX and ONEPROD KITEonline System, ONEPROD NEST ANALYST can be fully automated. The respective roles of these 2 elements are:

NEST ANALYST is used to configure MVX and KITE

NEST ANALYST is used to control MVX and KITE: start-up and stop of monitoring and acquisition tasks.

Once started, MVX and KITE perform monitoring and acquisition tasks programmed in NEST ANALYST. These can be:

o Periodic with a periodicity depending on the alarm level of the equipment o On alarm status change o On operating condition change

NEST ANALYST stores, processes and displays all acquisitions transferred by MVX or by KITE. Analysis of on-line data is similar to that measured with a collector.

NEST ANALYST also records all events: o Equipment status changes o System defects: sensor, MVX or KITE, communication, etc.

Note: with the on-line option, the display and the database are constantly updated with the new data provided by the ONEPROD MVX and ONEPROD KITE Systems. During some set-up operations, the

display update may be suspended. This situation is indicated with the flashing of symbol in the top banner of ONEPROD NEST ANALYST Display will be reactivated as soon as changes are validated. This blocking does not affect the update of the database.

Definition of MVX and KITE channels 5.11.4.

The following step consists in defining the way to use each MVX or KITE channel. To do so, edit their properties:

Select the channel (left click) or several ones (ctrl left click)


Select Properties

First define the type of input:

IEPE (AC): accelerometer or velocimeter powered by constant current

70

Brand of ACOEM

IEPE (DC): temperature output integrated to some accelerometers. This type of input supplies a constant current.

TriggerTachometer: rotation frequency measurement from a signal supplying one or several trigger inputs

Voltage input AC + DC: voltage input of dynamic signals that can have a continuous component (e.g., a proximity probe)

Process input DC: continuous voltage input

Process input 4-20mA: continuous current input

Pulse counter: this type of input is used with the CGI parameter for particle counting.

Voltage input with thresholds Set-up depends on each type of input:

IEPE (AC):

o Input unit: select from a list o Sensor sensitivity in mV/input unit o Amplification: 1, 10 or 100 Note: for IEPE channels, if a real-time parameter is connected on this channel, the Amplification field is not taken into account.

IEPE (DC), Process input DC:

o Input unit: select from a list o Label if « other »: label of the unit if « Other » is selected. 5 characters max. o Sensor sensitivity in mV/input unit o Input offset (input unit): This offset is used to correct the result based on formula:

Result in input unit = (Input in V)/(Sensitivity) + (Offset in input unit) o Amplification: 1, 10 or 100

4-20mA Current Input:

o Input unit: select from a list o Label if « other »: label of the unit if « Other » is selected. 5 characters max. o Value measured in EU at 4mA: indicate the parameter value in input unit corresponding

to 4 mA o Value measured in EU at 20mA: indicate the parameter value in input unit corresponding

to 20 mA

Voltage input AC + DC:

o Input unit: select from a list o Sensor sensitivity in mV/input unit o Input offset (input unit): This offset is used to correct the result based on formula:

Result in input unit = (Input in V)/(Sensitivity) + (Offset in input unit) o Gain: 1, 10 or 100

71

Brand of ACOEM

TriggerTachometer:

o Input unit: Hz o Type of trigger: on positive or negative slope o High triggering threshold (Volts)*: value from -24 to +24 o Low triggering threshold (Volts)*: value from -24 to +24 o Number of impulse per revolution: Integer from 1 to 65536. The resulting rotation

frequency is equal to the frequency of impulses / Number of impulses per revolution.

* High threshold and Low threshold: to rearm the trigger System for next acquisition, it used to avoid wrong triggering.

Pulse counter:

o Input unit: p (Particles). This type of input is used with the CGI parameter for particle counting. The sensor used generates an impulse for the passing of each particle (see § 14.12). The following 2 parameters are to be set depending on the amplitude of the impulse delivered by the sensor.

o HIGHER triggering threshold (Volts)*: value ranging from -24 to +24. Default value: 12 V o LOWER triggering threshold (Volts)*: value ranging from -24 to +24. Default value: 10 V

After set-up, the channel is displayed in the instrument tree structure along with the selected unit:

High threshold Low threshold

Triggering point

Rearm point

Trigger on positive slope

Low threshold

High threshold s

Voltage input with thresholds: Sensitivity curve is defined by 2 points (Min and Max). This input type can also detect an overload if values are outside the saturation threshold limits:

Lower and Upper Saturation thresholds in physical unit

Minimal and maximal voltage, in volt.

Lower and Upper physical limits, in physical units. Sensibility (V/unit) and offset of the channel are automatically calculated using voltage output and physical limits. It is required to connect to this channel parameters or signals using the same input/parameter unit as the sensor unit.

Saturation thresholds

Used when it is needed to give the feedback that values are outside of the range. There are set in the physical unit.

If saturation feature is not wanted, set both Upper and Lower saturation threshold to zero.

MVX and KITE Channels / NEST ANALYST Equipment Points Association 5.11.5.

Hard parameters and signals of ONEPROD NEST ANALYST must now be associated with ONEPROD MVX or KITE channels. This association can be done globally point by point:

After association, the channel label is displayed in the Channel » columns for Points, Signals and Parameters:

1 – Select point

2 – Left click on the MVX or KITE channel to associate then right click and “Connect”

74

Brand of ACOEM

Notes:

Several sensors associated with a single point: it is also possible to do this association at the parameter level. This allows to sort parameters originating from different sensors in a same point, e.g., vibration and temperature:

Coherence control: For each association, a coherence control is done to check: o The compatibility between the type of input and associated parameters and signals o The compatibility between programmed measurements and the ONEPROD MVX

performance In case of non-compatibility, the association will not be done and a message will inform the operator thereof.

On-line / Off-line sensitivity: For each association, the sensitivity of the measurement channel is compared to those of the point measurements. If they do not correspond, a warning message is displayed. The sensitivity used for measurements performed with ONEPROD MVX or KITE is that entered for the channel. Those defined for the parameters and signals are used for measurements performed with a data collector.

Several machines can be monitored with a single ONEPROD MVX or KITE.

This version of ONEPROD NEST ANALYST / ONEPROD MVX does not allow for the monitoring of a piece of equipment with points spread over several ONEPROD MVX or KITE.

Assistance for channel association: o Tree filtering: connected or non-connected channels can

be filtered. To highlight the presence of a filter, tree labels are displayed in blue.

o Navigate to: to facilitate the search for the element corresponding to an association, you can use the “Go to” function in the context menu:

Either from a channel measurement (double click

on the channel to display the measurements). The corresponding element will be automatically selected.

Or from the configuration mode programming tab. The corresponding element will be automatically selected. In the Equipment tree.

Correction of association: it is also possible to cancel any existing association using the “Disconnect“ function available in the context menu of any connected point, signal, parameter or channel. This function is also available from the ONEPROD MVX or KITE; it will cancel all existing associations with this instrument.

Set-up of logical outputs and Modbus ouputs of MVX and KITE 5.11.6.

To program ONEPROD MVX and KITE outputs, display ONEPROD MVX properties again.

The “Output control” tab can be used to define the behaviour of the 4 to 8 outputs available in ONEPROD MVX and KITE. Each output can be set to have a manual acknowledgement or not:

o A “maintained” output remains in alarm status even if the corresponding status goes back to normal and this until manual acknowledgement of MVX. This acknowledgement is done from the logical input defined in the first tab.

o A non-maintained output automatically returns when the level goes back beyond the hysteresis threshold defined with absolute thresholds (see § 5.5.5).

One can also define whether the Normal status of the output corresponds to its active or disabled state. Caution: if option “Active normal status” is selected, then switching the MVX off might cause relays driven by these outputs to switch to the alarm mode.

The “Address” tab can be used to define the outputs activated by each parameter connected to the ONEPROD MVX or KITE when it goes in alarm or danger mode. Enter 0 if you do not want to activate the outputs. When many parameters are managed by a MVX, we recommend the used of the “Filter channel” tool for this programming. The last column is used to manage the parameter order in the “Modbus” table when this function is used. It gives direct access to parameters monitored by MVX from a third application via a Modbus/RS communication protocol on the RS485 output or on Modbus/TCP on the Ethernet interface.

Programming MVX and KITE acquisition conditions 5.11.8.

In addition to its permanent monitoring tasks, ONEPROD MVX and KITE can trigger automatically acquisitions retrieved and stored in ONEPROD NEST ANALYST. This automatic routine is programmed in the “Operating conditions” tab of the “Configuration” mode:

You must define C, S and T as well as the priority for the Default Condition:

C: used to trigger an acquisition each time an operating Condition occurs. Do not select this option if no operating condition has been previously defined. For more information on the programming of operating conditions, refer to § 5.11.12.

S: used to trigger an acquisition on the equipment on each change of alarm Status of a parameter. These acquisitions can be limited to aggravating status changes (from OK to AL and from AL to DG) and to the point having changed status, based only on the options selected in the "Acquisition” tab.

P: can be used to trigger periodic acquisitions. Periodicities are selected in the ”Acquisition” tab. The periodicity can be shorter when the equipment is in alarm status. A “P” measurement is performed when the periodicity change (if the equipment status goes from OK to AL or DG or if goes back to OK)

Note: Caution – if the three C, S and P checkboxes are not checked, ONEPROD MVX or KITE will be limited in its monitoring function and will not transfer the measurements to ONEPROD NEST ANALYST.

Priority 0, 1, 2: A priority is given to each acquisition task. This feature is used to manage ONEPROD MVX and KITE resources when several machines are monitored. This allows, e.g., to allocate greater priority to the acquisition of a non-recurring event, such as the capture of the time signal during the machine shutdown.

Brand of ACOEM

Programming MVX and KITE acquisition 5.11.9.

You must then set-up the “Acquisition” tab: Select first the “ON-LINE” option.

Acquisition strategy on status change (if S is checked in the Operating conditions tab): o All status changes or aggravating status changes (OK to AL and AL to DG) o Measurements on all the equipment or only on the ONEPROD MVX or KITE acquisition

channel that detected the alarm. CAUTION: The option “MVX channel only” should not be used if monitored parameters originate from an OPC source (see § 21). In case of an alarm on an OPC parameter, no measurement will be triggered.

o Option “Measurements on status change are stopped…” allows limiting the volume of data transferred and stored on status change. Some defective machines can indeed show very unstable operating, which induces constant switches between OK and alarm status, hence generates a huge volume of data to transfer and store. In particular for wind turbines. When this option is selected, the operating is as follows in case the number of status changes is exceeded:

MVX stops transferring the measurements on status change until the end of the current day (the counter is reset to 0 at the end of the calendar day)

An event to acknowledge is displayed in the event log: “Maximum number of status changes is exceeded for ‘Equipment’’“

The number of these non acknowledged events is displayed in the upper banner. Icon is displayed as soon as this number is greater than 0.

It keeps transferring periodic measurements.

Acquisition periodicity (if P is checked in the Operating conditions tab). Two periodicities must be defined: the periodicity when MVX does not detect any alarm status on the equipment and the periodicity when the equipment is in alarm mode. An additional parameter allows not transferring signals Systematically (spectra and time signals) at each measurement but only once every N periodic measurement (N ranging from 1 to 255). The default value is 1; it allows having signals for all measurement dates. Periodic measurements with no signals are tagged with character “p” in the list of measurement dates.

Notification: An SMS or e-mail notification can be sent out for an event. See § 20 for details on the set-up of this function.

Alarm triggering delay: this function aims at avoiding untimely alarms related to noise or transient phenomena (e.g., related to the start of a neighbouring machine). It consists in validating an aggravating alarm status only if it is confirmed after the indicated time. If the defect disappears before, no alarm is issued. The effective value of this time shall not be shorter than the MVX measurement cycle, which depends on the programmed parameters and signals.

Short-term trend: ONEPROD MVX and KITE can memorise the last monitored values in an internal buffer. The properties of this buffer are:

o Number of values : integer from 0 to 1000 o Minimum periodicity: from 0 to 600 s. The real value of this periodicity shall not be smaller

than the MVX measurement cycle, which depends on the programmed parameters and signals. For real-time parameters the periodicity can be disturbed by the processing tasks with higher priority. The periodicity is at least 1 second.

The short-term buffer can be consulted directly in “Supervision - On-line” mode (see § 5.12.3). It can also be stored in ONEPROD NEST ANALYST, either manually from the “Operation - On-line” mode (see § 5.12.4.6), or automatically upon an aggravating status change for the equipment:

o Memorisation upon aggravating status change: check this option to automatically transfer the data to NEST ANALYST

o If the option is checked, the short-term buffer is transferred along with each measurement date for any aggravating status changed until acknowledgement of the alarm or until the defined storage limit is reached (maximum consecutive length to store: integer from 0 to 10000)

Short-term data thus stored in ONEPROD NEST ANALYST can be consulted from the “Operation – List of measurements” mode (see §5.12.4.8) Short-term data can also be deleted from the NEST ANALYST database (see §11.15) WARNING: short-term buffer increases the load of the System and can reduce its performance.

Time wave on event: with its DAT option, ONEPROD MVX includes a new type of time signal. The specificity of this signal is that it can be triggered at any time by an event and that it has a pre-trigger notion, i.e., it can capture a part of the signal before the triggering event.

Triggering events can be:

o An aggravating status on a real-time parameter (see § 13) if box S is checked in the “Operating condition” tab.

o A change of operating condition if box C is checked. o A request for manual measurement

Notes: A status change on a cyclic parameter (not a real-time parameter) does not

time signal on event. A periodic measurement does not trigger a time signal on event.

This signal is sampled at 51.2 kHz. Its length is configured globally for each machine in the “acquisition” tab. The value is expressed in seconds. The maximum length will depend on the number of channels with a time signal on the MVX. The table below gives an indication on this maximum value:

It is then possible to have up to 10 operating conditions, including a fallback condition, which is activated automatically if the availability of an OPC operating parameter does no longer allow for normal management. Programming the operating conditions of a machine requires the following steps:

From tab “Programming” 1. Definition of operating parameters. 2. Definition of monitored parameters and measured signals for all operating conditions.

From tab “Operating conditions” 3. Creation of operating conditions:

Definition of each operating condition

Definition of acquisition strategy

Definition of limit values of operating parameters

Assignment of corresponding measurements.

From tab “Acquisition“ 4. Definition of acquisition periodicities

Let us consider the following example:

The machine is equipped with the following instruments:

A tachometer to determine the operating speed of the machine

A TTL input to detect the stop of the machine

Two accelerometers mounted on each one of the 2 bearings of the machine Let us define the 3 operating conditions of the machine:

Name of condition

TTL input Rotation speed Measurements performed on each point

Shutdown Off 0 – 1500 RPM Time signal only on occurrence of the condition, i.e., during the coast-down phase

Low speed On 900 – 1200 RPM Monitoring measurements (Overall level for velocity and broad-band acceleration) and analysis (200, 2000 and 20000 Hz spectra)

High speed

On 1200 – 1500 RPM Monitoring measurements (Overall level for velocity and broad-band acceleration) and analysis (200, 2000 and 20000 Hz spectra)

5.11.12.1.Defining operating parameters

Operating parameters are used to characterise the operating condition of the machine. Up to 6 parameters are available for each machine:

1 parameter relative to the rotation speed measured from a trigger input or from a continuous input. This parameter is present on all machines, as it is also used to extract the amplitudes relative to the machine kinetics.

2 parameters relative to the process (flow, pressure, loads, …) measured from continuous inputs

3 logical parameters (On/Off, Open/closed, …) measured from logical inputs These parameters can be:

Either measured directly by ONEPROD MVX or KITE,

Or transferred from the process through the OPC protocol. This 2nd

possibility requires that ONEPROD NEST ANALYST include the OPC Client option (see §21).

In our example, the rotation speed must be set to “variable”. An example of measurement programming from a trigger input is given below:

Property of the rotation speed parameter:

Property of the ONEPROD MVX and KITE channel that will be associated with this parameter:

86

Brand of ACOEM

The “On-Off” parameter measured from a logical input must also be added:

Property of the ONEPROD MVX or KITE logical channel associated with this parameter:

5.11.12.2.Defining monitored parameters and measured signals

Measurement points and their parameters and signals are created like for machines with no conditions (see § 5.5.2 and following ones). Example:

Important note: in order to be able to further use the thresholds set-up wizard (see § 6), we recommend defining the higher alarm type for all monitored parameters before going to the next step.

5.11.12.3.Creating operating conditions and assigning points and measurements

1. From “Operating condition” tab with “New condition” contextual function:

2. Enter the label and the name for the new condition: 3.

Then you get the first operating condition:

88

Brand of ACOEM

In addition to this 1st operating condition, ONEPROD NEST ANALYST creates by default a

specific condition called “Fallback condition”. This condition will be used in the 2 following cases: - Some operating parameters originate from an OPC source and NEST ANALYST can no

longer access to the OPC server, thus preventing ONEPROD MVX from determining the current operating condition. This allows programming the measurements that MVX will have to perform in this degraded mode.

- The fallback condition can also be measured upon an immediate request for measurement (see § 5.12.4.6) if ONEPROD MVX or KITE is a non-defined operating condition:

4. You have to define the operating condition:

Description of the Operating condition: o The Colour code identifying the condition: double click in “Abv+Col” column. Select

colours other than green, yellow and red as these are used for alarm statuses of machines.

o The Delay allowing defining a waiting time between the occurrence of the condition and the acquisition. This is used to ensure that the speed is stabilised when the acquisition starts.

o The Stability of the condition parameter defines whether the condition is maintained of not during all the acquisition:

Yes: the acquisition will be stopped if the condition is no longer present during the acquisition. No measurement is stored.

No: the acquisition will be completed even if the condition is no longer present at the end.

o %RPM: it is used to control the variation of the rotation speed in order to stop measurements if the speed is not stable enough during acquisition. This defect is displayed in the “Event panel” and “Alarm and properties” windows. If %RPM = 0, rotation speed stability is not controlled.

Description of the Acquisition strategy. (For more details on C, S and P see § 5.11.8) The screen below will illustrate our example: o Low speed condition (LS) and high speed condition (HS) are measured at each status

change (S) and at fixed periods (P). Periods consist in one measurement per day when the machine has no alarm and one measurement every 2 hours if there is one alarm.

o The shutdown condition (Stop) is measured each time such condition occurs (C). If ONEPROD MVX or KITE monitors other machines, a higher priority can be assigned to this task (priority level 0).

The lower part of the window is used to define operating parameter values or corresponding limits for each condition:

In our example:

89

Brand of ACOEM

Association of points and measurements: all points and parameters are selected by default in a new operating condition. If some measurements (or points) are not needed for a condition, it is possible to unselect them. Corresponding lines (or columns) of PSS are then not measured for this operating condition.

In our example:

“Low speed” and “High speed” operating conditions: time waves (ShtDownWav) are not measured

“Stop” operating condition: time waves (ShtDownWav) are measured and only this one

5. In the “Programmation” tab, yon can control the result of your action by filtering points and

parameters associated with a conditions:

The BLUE colour indicates that a filter is active and that some points or parameters may be hidden.

91

Brand of ACOEM

5.11.12.4.Programming the acquisition strategy for each operating condition

You have now to define the acquisition periodicity: once a day if no alarm and each hour if the equipment is on alarm.

Acquisition time-out: if a periodic acquisition is performed on a machine with operating conditions, the condition may not be present at the time scheduled for the measurement. In this case, the System will monitor if the condition occurs over a period at least equal to the Acquisition time-out. If, during this delay, the condition occurs then the measurement will be performed, otherwise it will be cancelled until the next scheduled time.

92

Brand of ACOEM

5.11.12.5.Particularisation of thresholds for each operating condition

Thresholds can be adapted to each parameter according to the operating condition. To do so, use the “Programmation” tab and filter the condition for which thresholds have to be customised. For instance, for the low speed condition:

All parameters must be adjusted one by one or can be changed directly from the Operations mode provided the measurement list includes at least one measurement for the operating condition. To do so, select a date at the operating condition, point the cursor to the parameter with the thresholds to change

and click on the “Alarms and properties” for quick access to the alarm threshold settings.

1 – Filter on condition 2 – Select the condition to change

3 – Open window “Alarm and Properties” with button

4 – Select parameter to change then adjust thresholds in window “Alarm and Properties”

System control 5.11.13.

The System records automatically all significant events. These deal either with alarm status changes on monitored machines or with integrity defects in the System.

5.11.13.1.Event counter

An indication ( ) appears in the upper banner as soon as a non-acknowledged event is detected:

This information lists the number of non-acknowledged events and the total number of recorded events. This indicator disappears when all events have been acknowledged. Icon indicates that measurements on a non-acknowledged status change are stopped for at least one piece of equipment: see § 5.11.9.

5.11.13.2.Event panel

To see the list of events, open the event panel with button :

This window displays the event chronology, the most recent being listed at the bottom of the list. This list

is limited to the 100 last messages. Older events are accessible in the log file ( ). The type of events displayed can be adjusted from the Administration module. There are two categories of events:

Simple information written in black: these are non-critical events (e.g., back to normal for a parameter status) or an action performed by the operator (e.g., stop or start of a ONEPROD MVX).

Alerts written in red: these are aggravating status changes for parameters and detection of System defects (communication problem, sensor defect…). These alerts remain in red until they are acknowledged by the operator. This operation is carried out using the context menu after selection of the event(s) to acknowledge:

94

Brand of ACOEM

After acknowledgement, alerts are displayed in black and the name of the current operator, as well as with the date of acknowledgement, is added.

Other functions are available in the context menu:

Delete selected events to clean the list from already processed events.

Go to the element: this function is used to select immediately the corresponding Equipment or ONEPROD MVX in Instrument or machine Explorer.

Access to Acknowledge and Delete events function depends on the user profile. In order to find a specific event, the list can be filtered by type of events:

Consulting the control results 5.12.

Principle 5.12.1.

Results can be consulted in two different places:

In the “Location/Equipment hierarchy” tree where the most recent alarm status is displayed for each equipment

In the “Supervising mode” window to have access to data as block diagrams or in ”Exploitation mode” window where all results are available as a matrix.

“Location/Equipment hierarchy” tree 5.12.2.

5.12.2.1. Principle

The “Location/Equipment hierarchy” tree can be used to navigate quickly within the production assets and to view the latest alarm status for each machine under monitoring at any time. These statuses are represented by an icon:

Alarm statuses are coded as follows:

DANGER At least one parameter in DANGER

ALARM At least one parameter in ALARM

PRE-ALARM At least one parameter in PRE-ALARM

OK All parameters are OK

UNKNOWN No parameter has been measured or calculated

This alarm status corresponds to the alarm status generated by the most recent control performed on the equipment. This status is obtained by combining parameter and measurement point alarm statuses. Important note: parameter status is not moved up to the equipment level if option “Monitored” is not selected: see § 5.5.6. The alarm status of each location is coded as follows:

DANGER At least one equipment in DANGER

ALARM At least one equipment in ALARM

PRÉ-ALARM At least one equipment in PRE-ALARM

OK All equipment are OK

UNKNOWN No equipment has been measured or calculated.

5.12.2.2. Filtering options

In order to find more easily a set of machines, one can have the tree display only those machines meeting criteria defined in the filtering module. To display the windows showing current filtering, select option “Tree

filter” in the menu bar. The following filtering operations are available: o “Status” tab:

o Filter on the alarm level, e.g., display machine with alarm or danger status only.

o Filter on advice, to, e.g., rapidly find equipment with “no advice” that has not been validated by the expert.

o “Dates” tab:

o Filter on date of last measurement, e.g., display only machines measured recently. If “PSS/SSS Filter” is selected, the filter is applied on the list of measurement dates of “Operation” mode.

o Filter on date of next measurement. You can use this option to build up your own routes or control that no piece of equipment was omitted. The date of next measurement is calculated from the periodicities defined in “Configuration” mode, Acquisition tab.

o “Selections” tab: Filter on one or several selections, e.g., to show

only routes that have just been downloaded. Filters are applied only if option “Filters on” is selected. (Active filters)

Button in the filtering window is used to reset all options of the filters. Equipment and location names are displayed in blue as a filter is active. Note: filter settings are saved for each user for his/her next session.

“Supervision” mode 5.12.3.

5.12.3.1. Principle

The supervision mode is selected from the upper banner:

This mode is used to display a diagram for each element of the Equipment tree. This diagram is made up of a background image (selected in the item properties) with all sub-elements being superimposed.

All sub-elements are initially positioned in the top left corner of the window. They can be freely moved around by dragging them with the mouse. It is also possible to hide some elements. Those operations are possible only for users having the right “Supervision” in their profile (see “Administration manual”). On a location level, there is:

o either a sub-location: o or an equipment:

The maximum number of sub-elements is 32. Click on a location to display the next level down and this down to the equipment level.

The Equipment level presents the following elements:

An equipment diagram can include up to 32 points and 12 parameters per point. Two visual display modes are available: “List of measurements” and “On-line”

5.12.3.2.Supervision - List of measurements mode

This mode is available for location and equipment levels.

The alarm status displayed is the most aggravating* status since last acknowledgement. Items not acknowledged are indicated by a blinking** of the alarm indicator and by “!” mark. It remains until the alarm is acknowledged by the operator. Acknowledgement is available directly from the supervision screen with the context menu of equipment, points or parameters. The alarm status is memorized until the alarm is acknowledged. After acknowledgment the status shows the current value. Acknowledgement performed for a piece of equipment or a point will be valid for all sub-elements. Acknowledgements are traced back in the event panel.

Displayed values correspond to the latest values stored in the database (Measurement date on top of the list of the Operation mode). The trend curve is that of the values stored in the database.

* Alarm status is classified in following order: OK , Error , pre-Alarm , Alarm and

Danger . ** blinking may be disabled in the user preference. In this case items not acknowledged can be identified with the “!” mark (see § 11.2). Remark: if the last measurement is deleted, the statuses of not acknowledged items are not changed.

For a machine under on-line monitoring, current levels can be displayed:

Values are automatically updated with the selected updating periodicity. Remarks:

Displayed values are not stored in thedatabase.

A Warning is displayed if the periodicity is too short regarding the load of the System. In this case

it is recommended to use a higher value as it can lead to decrease the performance of the System.

Button “Add measurement” is used to start an acquisition at any time. The “short-term” checkbox allows filling out the measurements with the contents of the ONEPROD MVX or KITE short-term buffer. After completion, it can be consulted in the “Measurement list” mode. Three sizes of PSS/SSS window are available to adjust it to your screen and application requirements.

5.12.4.7. “Vibration & Process” view

This view displays the vibration and/or process parameter history for the current equipment, as well as the corresponding alarm status. This matrix view is named “Parameter Status Screen” or “PSS”. It presents the value and the associated alarm status for all the equipment parameters obtained during a given date. Reading the matrix:

The “Balourd” (“unbalance”) parameter calculated on the “RADIAL COA” measurement point presents a value of 2.56 mm/s and an alarm status “OK” for the measurement of 17/01/2003 at 16h18.42s.

The same “Balourd” parameter calculated on the “RADIAL CA” measurement point presents a value of 32.6 mm/s and an alarm status “DANGER” for the measurement of 17/01/2003 at 16h18.42s.

This view is then very useful to easily consult values and alarm status of parameters under monitoring, as well as to follow up their history throughout the successive dates: Options at the top of PSS can be used to hide some parameter types:

In our example for the download of “Route_A”, this view displays the values obtained for all parameters on equipment “M.P104” and “P.P101” during the most recent control performed with the collector:

Downloading the collector has generated a new measurement dated 17/01/2003 at 16:18:42. Measured or calculated values for all monitoring parameters are associated with this control, hence an alarm status. We can observe that the alarm status of “P.P101” switched to ALARM since at least one parameter is in ALARM mode.

To do so, from the Operations mode of the main window of ONEPROD NEST

ANALYST Then select the measurement date in the list of measurements. Go to the “Archives” tab of the selected measurement date and

than click on “Add”:

Select whether to store the file in the database (Yes) or to set a link to this file (No):

The files thus added will then be accessible ( “Display” or “Extract”) directly from the “Archives” tab of the measurement date:

Note: The added files can be deleted by selecting the file(s) to delete and then “Remove”.

Editing a report 5.18.

Report editing tools allow creating documents HTML (Internet Explorer), PDF (Acrobat Reader) or RTF (Word compatible Rich Text Format) documents providing information on the operating status of the production assets as well as on the monitoring modes of each piece of equipment. Two types of reports are available:

Statistical reports available from the context menu “Statistic reports” or from button in the vertical toolbar. These reports are described in the “ENGLISH_ViewerUsersGuide.pdf” document. When this module is started from ONEPROD Viewer, it provides access to statistical analysis reports based on expert advice, machine types, machine functions and defect types. When launched from NEST ANALYST, the module provides access to 2 statistical analysis reports based on alarm statuses. Examples are presented in Appendix 7 (see § 0).

Standard reports are available from the context menu “Reporting…” or from button in the vertical toolbar. These reports are described later in this paragraph.

A report is achieved from the current selection in the production assets tree structure and complies with a list of user-defined options.

Editing options are used to select a predefined selection of equipment, e.g., a route, as well as the control date to edit. Option “Date with advice only” is used to automatically exclude from the measurement dates that have not been validated by the expert. The current equipment selection is that selected in the production assets tree structure, and the default control date is that of the most recent control performed on each piece of equipment. Other options are available to select the type of alarm and of parameters to edit. Traceability information and inspection notes can be edited (or not).

Customisation of reports Reports are based on templates that can be modified in Word to adjust the page layout to the needs of each user. When a new database is created, the general templates are duplicated into a directory specific to each database. The general template files are located in the sub-directory “ONEPROD\XPR\srv\Reports\ReportsStd” of the installation directory. The modifications must be done in this folder to be effective for all futur databases. To adapt the reports of a specific database, one must change the template file corresponding to this database. For instance, the standard report template for database d1\w1\b1 is file “ReportsStd_AMERICAN.rtf” located in directory:

ONEPROD\XPR\BIP\xmlp\XMLP\Reports\ediag\d1\w1\b1\ReportsStd The character fonts can also be changed, as well as the information order. Some pieces of information can also be removed. Before each modification, we recommend saving the initial template file. Several template files can be created. The name of each template file must end with “AMERICAN.rtf” (AMERICAN corresponds to a use in AMERICAN language). The template file is selected in the report editing interface:

THRESHOLDS SET-UP WIZARD 6.

This wizard allows selecting the measurements performed on a machine using ONEPROD MVX or KITE or ONEPROD MVP over a period when the machine was considered as having an OK status. This observation period provides a good basis of statistic information on the behaviour of the machine in its different operating conditions. Selected values are automatically analysed so as to determine the thresholds to apply for each parameter and each operating condition. If observation is not sufficient enough, this operation can be repeated at any moment. Notes:

This function is not available in NEST ANALYST Easy Level

This function only takes into account the parameters with a “High” alarm type, which is the case for most parameters that are commonly used.

If after running this wizard, the user wants to be able to revert to the previous thresholds, he/she must copy/paste the equipment and its history before.

The wizard is used in “Operation / List of measurements” mode. It includes 6 steps:

Step 1: Selecting measurement dates 6.1.

Successive dates 6.1.1.

If the selected measurements are successive measurements, start the wizard directly form the context menu in the list of measurement dates:

Step 1 allows for the selection of the limits of the measurement period to analyse:

Click on “Next” to go to the next step.

Non successive dates 6.1.2.

If selected measurements are not successive measurements, one must first select the measurement dates on the list and then start the wizard using the context menu:

In Step 1, check that option “Use selected measurement dates” is selected:


Step 2: Selecting operating conditions 6.2.

If several operating conditions are detected, Step 2 allows selecting those for which the thresholds need to be set.

This step does not appear if only one operating condition is detected. Click on “Next” to go to the next step.

Step 5: Setting up calculation coefficients 6.5.

Step 5 allows “customising” the coefficients used in the calculation:

The principle used here is based on the statistical analysis of the measurements. For each parameter and in each operating condition, the System calculates:

Avr = the average of the parameter values for an operating condition

SDv = the standard deviation of the parameter values for an operating condition Thresholds are calculated using coefficients Cmin, Csd, Cmax, Cal and Cdg:

Calculation of the pre-alarm threshold: o Min pre-alarm = Cmin*Avr. The pre-alarm shall not be smaller than this value. o Pre-alarm = Avr + Csd * SDv.

This value will be assigned to the pre-alarm if it is not contained between “Min pre-alarm” and “Max pre-alarm”.

o Max pre-alarm = Cmax* Avr. The pre-alarm shall not be greater than this value.

Calculation of the alarm threshold: Alarm = Cal * Pre-alarm

Calculation of the danger threshold: Danger = Cdg * Pre-alarm Note: this System can be used if only one measurement date is selected. In this case, the standard deviation is equal to zero and the pre-alarm value is Cmin*Avr. The default values for the coefficients are:

Cmin = 1.2

Csd = 2

Cmax = 2

Cal = 1.4

Cdg = 3 Click on “Next” to go to the next step.

Step 6: Displaying results 6.6.

The last step displays the calculation results:

This table allows for the analysis of the new thresholds and for possible adjustments before the new thresholds become effective.

Results analysis 6.6.1.

Nb Val: Number of values used for the calculation

Min, Average, Max and Standard deviation: minimum, average maximum values and standard deviation calculated on samples selected for each parameter and each operating condition

New pAL, New AL and New DG: calculated values for the 3 thresholds. The pad is yellow if the new threshold is higher than its current value, which can allow detecting abnormally high levels in the observation period.

Nb pAL: number of PA threshold violations for samples selected for the calculation. The pad is yellow for all values greater than 0

Nb AL: number of AL threshold violations for samples selected for the calculation. The pad is yellow for all values greater than 0

Slope: indicator showing a positive slope for samples selected for the calculation. The regression line going through the measurements used for the analysis must not cross the pAL threshold calculated before the date of the last of these measurements plus the “Off-line measurement periodicity / If normal equipment” (Configuration mode, Acquisition tab). This indicator is calculated only of the number of values is greater than or equal to 4.

For a more detailed analysis of a specific parameter, one can plot its trend directly by using the context menu:

ESA OPTION: ELECTRIC SIGNATURE ANALYSIS 7.

Introduction 7.1.

The ESA function in ONEPROD NEST ANALYST results from the integration of the functions of the EMPATH 2000®.product:

EMPATH is a registered trademark of Areva NP. It stands for Electric Motor Performance Analysis & Trending Hardware.

ESA stands for: Electric Signature Analysis. The ESA function is an extension of the MCSA technique (Motor Current Signature Analysis), which is based on the analysis of the motor’s supply currents. The ESA function also analyses voltages, which allows identifying whether the defect origin is on the motor itself or comes from its power supply. The taking into account of voltages also gives access to the analysis of the power, torque and power factor. The implementation of the ESA function is very straightforward. It consists in entering the characteristic data of the motor. Most of these data are listed on the motor name plate. The generation of signals to measure and of parameters to monitor is fully automatic. Notes:

- This function is available only if ONEPROD NEST ANALYST includes the ESA option - Electric measurements are performed using the ONEPROD MVX System. ONEPROD NEST

ANALYST requires then the “On-line MVX” option. - Version 4.1 of ONEPROD NEST ANALYST does not allow performing electric and vibration

measurements on the same machine. In order to monitor both the electric and the vibration parameters of a machine, one needs to create two pieces of equipment in NEST ANALYST, one for each technique.

- Version 4.1 of ONEPROD NEST ANALYST is restricted to the analysis of induction motors powered up at fixed frequency (50 or 60 Hz) or by a VFD (Variable Frequency Drive). The EMPATH 2000 System also integrates the analysis of synchronous motors, direct-current motors, generators and transformers.

Principles of electric signature analysis 7.2.

Single and three phase induction motors are the most widely used motors in industrial and commercial machinery applications today. The larger motors used in industry are three phase squirrel cage design which are used to drive pumps, fans, compressors, and a wide variety of machinery. When subjected to an increase in load or torque the squirrel cage motor slows slightly and the supply current increases, resulting in an increase in horse power. Either an increase in torque or a change in speed will change the motor current, which can be used to sense the load torque or speed changes. Small load fluctuations show up as small motor current fluctuations on top of the line frequency supply current, and these can be detected with sensitive equipment. Because these load fluctuations can be caused by machinery vibrations that result from out of balance, misalignment, worn gears and belts, friction forces, and reciprocating elements, detection of the resulting current fluctuations can yield useful machinery diagnostic information. The motor current is sensed with a current transformer clamped around one of the supply leads usually located in the motor control cabinet, but any convenient cable location can provide the desired signal. On a three-phase motor all three phases can be measured using three current transformers if differences in the phase currents are suspected. Signal conditioning is required to produce useful signals. One of the primary operations of the System is to perform a root-mean-square demodulation process on the power line carrier signal to provide a highly sensitive and selective means of extracting current signals from the motor load. This demodulation of the raw current signal removes unwanted effects of the power line and its harmonics.

130

Brand of ACOEM

Numerous indications of performance are revealed within the time and frequency domains that provide the required information to determine the ‘health’ of the motor and the impact of the delivered load. This actually permits ‘seeing’ the true running speed, motor slip frequency, gear mesh speeds, drive train components, gear rotation, and tooth-by-tooth stress distribution. To separate the various frequencies a Fast Fourier Transform is used and the resulting frequency spectra are displayed on the screen. The peaks in these spectra correspond to the rotational speeds of the different components in the machine. For example, in the case of a fan driven by an electric motor through a belt, the peaks correspond to the motor speed, motor slip (pole passage), fan speed, and belt speed. If a gear box is used instead of a belt drive, then spectral peaks will appear at the shaft speeds and gear meshing frequencies. The heights of these spectral peaks depend on two things; the overall current level to the motor, and the amplitude of the mechanical disturbances coming from the machine and sensed by the motor. The mechanical disturbances start as torque variations and end up in the motor as small speed variations that in turn cause the small current fluctuations being measured. Motor Current Signature Analysis also provides useful information about the motor itself. When a fault in the rotor occurs, such as a broken rotor bar or a high resistance joint, harmonic fluxes are produced that induce currents in the stator windings. These induced currents increase the amplitude of the slip sideband peaks which occur close to the line frequency peak. Using demodulation techniques these sidebands are separated from the supply peak and made clearly visible so there is no confusion with other frequencies. This information about the rotor is valuable because failures can cause vibration, poor performance, and overheating. There is no other method of detecting rotor bar problems as accurate or precise as that provided by ESA. Even when the motor is disassembled, the rotor bars may not be visible because they are buried inside the rotor magnetic assembly.

Programming operating conditions and acquisition 7.4.

Programming operating conditions 7.4.1.

Further to the validation of the properties of electrical-type equipment, two operating conditions are Systematically created in addition to the fallback condition. They are available in “Configuration” mode in the “Operating conditions” tab.

The “Run-up” condition is designed to capture the time signal of currents during the start-up phase of the machine. The length of this time signal “HF Inrush TW” is that defined in the equipment properties. For each current, 2 parameters are extracted thereof:

“Max inrush current”: the maximum current value reached during the start-up phase

“Duration”: time required to reach this value. The “Steady state” condition is that used for the diagnosis of the motor when it has reached its operating speed. In order to manage these operating conditions, one needs to complement the equipment programming with operating parameters. For more details, see § 5.11.12.1. Important note about rotation speed: it is recommended to use a tachometer to measure the rotation speed. If this is not possible the System has an algorithm to calculate this speed based on electrical signals. It is important to note that the System may not return the correct value. On a new machine, it is strongly advised to check on the 1st measurements the relevance of the detected value. In the example below, a variable rotation speed and an On_Off logical input are used:

These parameters are used as follows:

The Run-up and Steady state conditions are active only if the On_Off is set to On. No measurement will be performed otherwise, i.e., if it is set to Off.

If the On_Off is set to On: o The equipment will be in Run-up condition if the rotation speed falls in the 0-45 Hz range o The equipment will be in Stationary condition if the rotation speed falls in the 45-50 Hz

range

These two conditions can be specified, deleted or other conditions can be added to adapt to the application. For more details on operating conditions, please refer to § 5.11.12.3.

Programming acquisition 7.4.2.

Acquisition periodicities needs to be programmed:

Comments on ESA measurements:

Measurements carried out for electric analysis represent an important load for ONEPROD MVX. At stationary speed, the acquisition lasts longer than 1 minute, to which processing time must be added. The total cycle time is about 2 minutes. It can be even longer if the same ONEPROD MVX instrument manages other machines. It is then important not to program too short periodicities so as not to overload ONEPROD MVX.

Measurements carried out for electric analysis includes signals only and no Hard parameter. The diagnosis results from post-processing upon download. Therefore, ONEPROD MVX does not perform any permanent monitoring. However, it is possible to complement the programming with manually created monitoring parameters.

One then needs to associate measurement points and ONEPROD MVX or KITE channels.

This must be done:

For the 3 current measurement points: C1, C2 and C3

For the 3 voltage measurement points: V1, V2 and V3

For operating parameters Note: Caution – The order for current association must be coherent with that of voltages so as to get correct values for the power factors. In the case of a Delta configuration (measurement of phase to phase voltage), it must respect the following convention:

V1 : - on phase 3, + on phase 1

V2 : - on phase 1, + on phase 2

V3 : - on phase 2, + on phase 3 For more details on the association procedure, see § 5.11.5.

Parameters of the electric diagnosis grid 7.8.1.

General comments for this paragraph:

Notations In this paragraph, the presented formulae use the following notations:

RS = Running Speed

RB = Rotor Bar count

FL = Line Frequency

SSL = Stator Slot count

Influence of input Voltage : The affects of input voltage on the motor can be determined by comparing the current and voltage spectra. If non-frequency line related peaks found in the current spectrum are not in the voltage plot, then the impact is considered to have originated within the motor or the driven load. If peaks line up in both the current and voltage spectra, then the source could be the incoming power and not necessarily associated with the motor being analyzed.

7.8.1.1.Power Factor

The power factor is calculated for each phase from the high-frequency time signals:

True power / Apparent power i.e.,

∫(C(t)*V(t))/( Crms*Vrms) If voltage is measured phase to phase, this value is performed from "phase-neutral” computed voltage signals.

Note: The calculation of the power factor will depend on the correct association between the measurement point and the measurement channel. This can be checked by displaying the high-frequency time signals. Two rules need to be checked:

The order of current phases and the order of voltage phases must be the same. In the example below, the 3 phases appear in the same order: red(1), green(3) then blue(2) for currents and voltages:

Plot of currents Plot of voltages

The power factor must be positive and of equivalent value for the three phases.

141

Brand of ACOEM

Example of bad association:

The current order is red(1), green(3) then blue(2)

The voltage order is red(1), blue(2) then green(3)

Plot of currents Plot of voltages

In this case, one must reverse the association of channels related to phases 2 and 3, either for voltages or for currents.

7.8.1.2.RMS value

The RMS value is calculated for each current phase and each voltage phase from the high-frequency time signal.

7.8.1.3.Peak value

The peak value is calculated for each current phase and each voltage phase from the high-frequency time signal.

7.8.1.4.Crest factor

The peak factor is calculated for each current phase and each voltage phase:

Crest factor = peak value / RMS value

7.8.1.5.Impedance

The impedance is calculated for each phase:

Impedance = Vrms / Crms

7.8.1.6.Static eccentricity

The determination of static eccentricity is based on the detection, in high-frequency spectra, of peaks at the following frequencies:

RS * RB +/- j*FL with j = 1, 3, 5, 7, 9, 11 The parameter goes into alarm status if at least 2 peaks are detected at more than 15 dB above the spectrum bottom.

7.8.1.7.Dynamic eccentricity

The determination of dynamic eccentricity is based on the detection, in high-frequency spectra, of peaks at the following frequencies:

RS * RB +/- j*FL +/- k * RS with j = 1, 3, 5, 7, 9, 11, … and k= 1, 2, 3 The parameter goes into alarm status if at least 2 peaks are detected at more than 15 dB above the spectrum bottom. It goes into danger status if more than 2 peaks are detected.

142

Brand of ACOEM

7.8.1.8.Stator mechanical damage

The determination of stator mechanical damage is based on the detection, in high-frequency spectra, of peaks at the following frequencies:

RS * SSL +/- FL The parameter goes into alarm status if at least 2 peaks are detected at more than 15 dB above the spectrum bottom. It goes into danger status as soon as it passes at least than 40 dB from the FL peak.

7.8.1.9.Bearing damage

The System searches for the peaks at the following frequencies: m[RS * BM] +/- FL with m = 1, 2,3 … with BM corresponding to the characteristic frequencies of the bearing.

The parameter goes into alarm status if at least 2 peaks are detected at more than 15 dB above the spectrum bottom. It is necessary that a bearing be associated with an equipment location, and that this location be associated with point C1:

7.8.1.10.Electrical unbalance

This parameter indicates, in percent, the maximum deviation with respect to the average value of the 3 phases. It is calculated based on the RMS values of voltages and currents. It needs to have the three phases measured. The parameter goes into alarm status above 3% and into danger status above 5%.

7.8.1.11.Harmonic distortion

Total harmonic distortion (THD All)

THD All = √{[(v22)+(v3

2)+ ….+(v50

2)]/[(v1

2)]}*100%

with vi = amplitude of harmonic i of the line frequency. It is calculated for voltages and currents. The parameter goes into alarm status above 5%. This distortion can be analysed based on its decomposition in positive, negative, zero, even and odd sequences. Harmonic distortion: positive sequence (+Ve)

+Ve = √{[(v42)+(v7

2)+(v10

2)+(v13

2)+ …]/[(v1

2)]}*100%

The positive sequence harmonics, the fundamental and 1/3 of all harmonic currents (4th, 7th, 10th, etc.), support rotation or sequencing in the same direction as normal motor action. These harmonics will actually cause the motor speed to increase while adding heat to the windings.

The negative sequence harmonics (2nd, 5th, 8th, etc.), oppose normal motor action and create magnetic forces on the rotor that oppose rotation, forcing the motor to work harder, drawing more current than its physical load requires. This added current could cause overheating and subsequent failure. When a motor is subject to negative sequencing harmonic currents, the fundamental current has to increase to overcome the negative torque caused by the harmonics. This adds to the heat already generated within the motor, can cause the motor load to be reduced to save it from overheating premature failure, and can result in mechanical impacts from the negative sequencing current induced torque that can cause bearing, coupling, and rotor damage. Harmonic distortion: zero sequence (Zero)

THD = √{[(v32)+(v6

2)+(v9

2)+(v12

2)+ …]/[(v1

2)]}*100%

The zero sequence harmonic currents (3rd, 6th, 9th, etc.), simply create heat, but do not affect either rotating or sequencing action. Their presence indicates non-linear loads that do not cancel, but, rather, add together in the neutral conductor. Harmonic distortion: odd sequence (THD Odd)

THD Odd = √{[(v32)+(v5

2)+(v7

2)+(v9

2)+ …]/[(v1

2)]}*100%

Either the THD or odd harmonics exceed 5%, which is usually indicative of a strong 3rd or 5th harmonic. A high 3rd harmonic in voltage means there is an induced high current unbalance with probable high neutral current; thus, the problem in the motor is most likely induced by the incoming power supply leading to excessive heating in the stator windings. When there is a strong 5th harmonic of current, it is added to the fundamental to produce a distorted, non-linear waveform, whose affect on the motor is to oppose fundamental motor action. Excess heat created by the effect of higher harmonics results in the following main failure mechanisms: eddy-current losses in motor cores and conductors; degrading effect on motor torque output caused by certain harmonics of electronic equipment on the same circuit as the motor; and overall effect of having more current than the motor was designed to handle. Harmonic distortion: even sequence (THD Even)

THD Even = √{[(v22)+(v4

2)+(v6

7.8.1.12.Running speed

It the rotation speed operating parameter is of ‘variable’ type, hence measured directly by ONEPROD MVX or KITE from a tachometric transducer, the value of the rotation speed displayed in the electric diagnosis grid corresponds to the measured value. It is the recommended method. If the rotation speed is not measured, the System will try to determine it by analysing the demodulated low-frequency spectrum of the current. It can happen that the spectral contents does not allow for speed extraction. On a new machine, it is strongly advised to check on the 1st measures the relevance of the value detected. Moreover, in this case the rotation speed thus calculated cannot be used as an operating parameter.

7.8.1.13.Demand power

The following formula is applied:

Demand power in kW = (1.732 * RMS current * RMS voltage * Power Factor)/1000

7.8.1.14.Motor load


Load = Demand power * Efficiency at rated load / Nameplate power.

144

Brand of ACOEM

The parameter goes into alarm status above 100% and in danger status above 115%.

7.8.1.15.Motor efficiency

The efficiency is calculated from a value table. The following parameters are used:

Efficiency level

Enclosure

Load The efficiency is not calculated if the load is smaller than 50%.

7.8.1.16.Output power


Output power = Demand power * Efficiency

7.8.1.17.Output torque


Output torque = Output power / Rotation speed in N.m: 9550 * Effective power (kW) / RS (RPM) in Ft.lb: 5250 * Effective power (HP) / RS (RPM)

7.8.1.18.Voltage variation from nameplate

This parameter indicates the difference between the voltage applied to the motor and the nameplate voltage:

100% * [Absolute value (Nameplate voltage – Voltage average) / Nameplate voltage] The parameter goes into alarm status above 3% and in danger status above 5%.

7.8.1.19.Rotor bar damage

This parameter provides a defect level on a 1 to 7 scale. The 7 levels are listed in the table below:

Category Rotor Condition Assessment Recommended Corrective Action

1 Excellent None

2 Good None

3 Slight indication of rotor problems Continue surveys, trend only

4 Rotor bar crack maybe developing or problems with high resistance joint(s)

Reduce survey intervals, trend closely

5 Two rotor bars likely cracked or broken & problems with high resistance joints likely perform vibration

Perform vibration tests to confirm problem source & severity

6 Multiple cracked or broken rotor bars & end rings indicated; also slip ring & joint problems

Overhaul ASAP

7 Multiple broken rotor bars & end rings very likely; severe problems throughout

Overhaul or replace ASAP

Several factors are used:

Importance of sideband lines at the pole pass frequency around the line frequency.

Importance of the peak at the pole pass frequency and of its harmonics in the demodulated spectrum.

7.8.1.22.THDF

THDF (transformer harmonic derating factor):

For current crest factor ≤ 1.414, VDF = 100% * { [current crest factor] / 1.414}

For current crest factor > 1.414, VDF = 100% * {1.414 / [current crest factor]} The parameter goes into alarm status below 95% and into danger status below 75%.

MANAGEMENT OF “OFF-ROUTE” MEASUREMENTS 9.

Introduction 9.1.

Movilog2 and ONEPROD MVP (Movipack) (from version V4.1 and higher) data collectors can manage a specific route allowing to create or change measurement points directly on the collector. This route is called “Additional point” route or “Off-route” route.

Downloading additional measurement points 9.2.

ONEPROD NEST ANALYST allows downloading “off-route” measurements from the collector. To do so,

go to the “Data collection – Offline” window (by clicking on ), select option “Off-route”, and start

downloading measurements ( ).

Notes

o If, when downloading a standard route, some of the measurements could not be assigned in the production assets, these measurements will be stored as additional measurements. This can occur if some elements have been removed form the production assets.

o The default downloaded routes are “PTS_SUPP” and “OFFROUTE” for Movilog2 and for ONEPROD MVP (Movipack), respectively.

Accessing additional measurements 9.3.

The “Acquisition / Additional measurements” function opens the window listing all downloaded additional measurements.

It is thus possible to configure up to 5 deletion profiles.

A profile splits the history of a machine into 3 sections:

Recent measurements on which no deletion is done

Short-term measurements for which measurements are deleted so as to keep at least one measurement every N days.

Long-term measurements where the interval between measurements is even longer.

In the above example, the 2

nd profile allows:

Keeping all measurements over 40 days since the most recent measurement date,

Keeping one measurement every 5 days up to 80 days before the most recent measurement date,

Keeping one measurement every 10 days beyond those 80 days.

Brand of ACOEM

Furthermore, the reference date, protected dates and dates with Advice are not deleted. Two options also allow keeping:

Dates on which a parameter changes status

Dates with non empty measurement information (diagnosis, recommendation, …)

For a machine with operating conditions, the history of each condition is processed independently of the other measurements. CAUTION: Periodic measurements with no signal (dates tagged with “p”) are Systematically deleted, except if they are subject to a non-deletion rule:

o Reference date o Protected o Advice different from “no advice” o If they meet the status change criterion and if option “keep dates with alarm status

change” is checked in the deletion profile o If they meet the « non empty measurement » information criterion and if option « keep

dates with “measurement information” ” is checked in the deletion profile You can then define a job to set when you want to run the deletion process:

Five different profiles can be creates and thus adapt to the different types of machines (criticality, online or offline measurements, etc.).

Selection of the deletion mode for each machine 11.7.2.

The selection is done individually in the Properties of each machine:

The “No data are deleted” option is selected by default when creating a machine or when copying/pasting. In this case, no deletion will be done even if manual deletion is launched for this machine. To use the deletion function, select the deletion (suppression) profile to apply. An option is available to automatically launch the deletion each time a new measurement is done on the machine. If this option is not selected, the deletion can be launched manually or according the the job scheduler define within the deletion profile.

Manual launch of measurement deletion 11.7.3.

You can launch a measurement deletion at any time for one or several machines. In the Equipment Hierarchy, select the machines for which the deletion is to be done. The context menu provides access to the « Delete measurement dates » function. After validation of the confirmation message, the measurement dates of each machine will be deleted based on the profile selected for each machine. Selected machines that have no deletion profile will not be affected by this action.

Protected access to the function 11.7.4.

The user profile available in the administration module includes 2 properties that allow controlling the configuration and the execution of this function, respectively.

Bearing libraries 11.8.

Principle 11.8.1.

The bearing database included in NEST ANALYSTONEPROD NEST ANALYST can be used to associate in an interactive way different measurement points of the equipment with different bearing references. This association performed via the “machine monitoring locations”, allows graphically superimposing all frequencies characteristics of selected bearings to the different spectra generated by the measurement points. The bearing database includes a management module with which the operator can manage its content (creation, modification and deletion of references). An import/export function is also available, allowing for the automatic update of the references from different databases (“merging” concept).

Definition of bearing references 11.8.2.

Access:

or The module for reference management opens up:

171

Brand of ACOEM

Three lists are displayed, representing the manufacturer list, the type list and the reference list, respectively. On top of the window, the total number of records contained under each heading is displayed. In the present example, the bearing database includes 35 manufacturers, 10 types of bearing and 30965 references. The reference list displays references relative to the manufacturer and to the type of bearing previously selected (current elements that are highlighted here). Characteristic frequencies given for each reference are given for a rotation speed equal to 1 Hz.

Import and Export of personal references 11.8.3.

If some bearings are not included in the database, the said database can be complemented with your own references: these references are called “personal (or private) references”. They are represented by symbol

. Other references cannot be changed and are represented by A new reference is added using the “New” function in the context menu. Input the bearing reference, along with the corresponding characteristic frequencies. The “Export” function is used to export all personal references contained in your database. These data can also be imported into another base, using the “Import” function. This function must also be used to backup private references. Note: the “public” bearing database is common to all bases of a System. Private ones are particular to each base.

Monitoring location libraries and association with equipment 11.9.

Principle 11.9.1.

Using the monitoring location library, the user can declare different zones of a machine, each corresponding to the field of influence of a mechanical organ (e.g., bearing). The current implementation allows to associate different measurement points with a monitoring location, and then to assign to this location all bearing references that may affect this set of measurement points. Right now, the concept of “monitoring place” is closely linked with the bearing database management module.

172

Brand of ACOEM

During the plot of a spectral signal belonging to a measurement point (hence to a monitoring location), bearing references of this location are automatically displayed along with the signal, which allows for a quick analysis of the possible bearing degradation.

Definition of monitoring locations 11.9.2.

The module for the management of reference locations is accessible from the “Libraries / Monitoring locations” menu.

This will open the module for the management of bearing references:

To create a new monitoring location, just enter an abbreviation and a label in the corresponding columns and validate.

Associating a monitoring location with an equipment 11.9.3.

Associating bearing references with a piece of equipment requires that bearing references be specified by monitoring locations. Monitoring locations should then be defined and then bearing references should be assigned to each of these locations. To do so, edit the equipment properties and go to the “Bearings” tab:

173

Brand of ACOEM

Then, press the location selection button and select a location in the library. This location can now be assigned bearing references, using the same method: press the bearing reference selection button and select:

The association “equipment – monitoring locations – bearing references” is now completed. For each piece of equipment, you now need to specify for each measurement point to which monitoring location it is assigned. To do so, edit the properties of each measurement point and assign to each point the appropriate monitoring location:

Now all spectrum plots will display as patterns the characteristic frequencies of the bearings associated with the equipment:

* Reminder – Real-time monitoring with MVX: some parameters can be set up to be monitored in real time by MVX. This means that MVX monitors 100% of the signal and hence can detect impulse-type events. Real-time parameters are:

Measurements of overall levels for Acceleration, Velocity, Relative displacement, Position and Process on DC input. In full display mode, an argument is used to set whether this parameter is monitored in real time or on a cyclic basis and to set its time constant:

The time constant is a value between 0.1 s and 600 s. If you use a small value, you can detect a short impulse in the signal. You can increase the time constant to avoid false alarms.

Narrow-band (MVX) and Broad-band (MVX): this type of parameter is monitored in real time if it is computed from a real-time spectrum (see. § 14.2)

GCI and BGI processings are real-time processings.

Real-time performance: MVX can manage up to 2 real-time parameters per channel on 32 channel or up to 4 real-time parameters per channel on 16 channels.

Slow down profile (MVP-2C) 14.9.

This processing allows controlling the slow-down duration of a machine. Example: The machine under monitoring is under rated operating conditions and is going to be stopped. The deceleration of the machine can be controlled by measuring the slow-down time for this machine between two speed thresholds called “Beginning speed” and “Ending speed” thresholds. A slow-down duration shorter than expected can reveal friction hence damage to the machine.

Title Description Recommendation

Beginning speed (RPM) Recording triggering threshold for slow-down time of the machine in RPM

12 to 60000

Ending speed (RPM) Stopping threshold for the measurement of slow-down time

12 to 60000 and <

Beginning speed

Delta TIME (sec) Maximum time between 2 points of the sampled signal: if speed has not varied significantly since the last point, a point is recorded after the indicated time delta

0.1 to 60

Delta RPM (RPM) Variation of maximum speed between 2 points of the sampled signal: a point is recorded after a speed variation higher than or equal to the indicated RPM delta for a time period shorter than the time delta

0 to 600

Full scale (parameter unit) Full scale value during recording for the y-axis in RPM

Limits:

o The maximum number is 1024 samples for a slow-down profile.

o The end speed can be set to 12 RPM but the time accuracy will depend on the passing moment for the last

pulse of the shaft rotation during the last revolution.

Recommendations for set-up :

o As a general rule, a slow-down profile with about 500 points is accurate enough to interpret the

measurement and compare it with a reference curve.

o The delta time and delta RPM parameters must be adjusted, in particular for machines with a high initial

rotation speed (> 3000 rpm)for a long shutdown time (>60 s).

193

Brand of ACOEM

o For the other machines, delta RPM can be set to 0 (maximum resolution with respect to the rotation speed)

Measurement, operating mode:

The implementation, in the measurement data collector, of the slow-down time must abide to certain rules:

1. wait for the display by the collector of the instantaneous rotation speed

2. wait for the rotation speed of the machine to be higher than the Beginning speed parameter value

3. wait for the bargraph displayed by the collector to switch to red and for the display of the “wait for

measurement to start” message

4. start the measurement

5. wait for 2 seconds to make sure the collector has taken into account the measurement triggering signal

6. ask the operator to trigger the slow-down of the machine

Example of a slow-down curve:

To compute automatically slow-down duration, you can use the duration post-processing: see § 14.21

Smaxpp (MVX, KITE) 14.10.

This type of measurement is available on ONEPROD MVX or KITE only. It allows monitoring the maximum displacement of the rotor centre (peak-to-peak value of the orbit). This monitoring parameter is worked out based on 2 proximity probes mounted 90° apart one from the other on the same bearing. IMPORTANT: Therefore, this parameter must absolutely be associated with 2 ONEPROD MVX channels. These channels must use the “AC+DC voltage” input and be expressed in µm or mils units.

SFI: Shock Finder Index (MVX, KITE) 14.11.

The Algorithm was developed purely to monitor slow rotating machinery, within the context of ONEPROD System. It mainly applies to the drive train on wind turbines, and it also can give machinery health indications on paper-manufacturing machinery, mills... The original concept is to base an alarm on the number abnormal of shocks received by the monitored equipment. The process is described as follows: - The algorithm filters the time wave signal in order to eliminate the noise, and reveal the shocks. - The algorithm then detects the shocks, and counts them on the time wave signal. - The algorithm uses a dedicated function to check the repetitive pattern over an observation period to

avoid false alarms. Remark: it is necessary to create first a time wave signal measurement. It is recommended that its sampling frequency is greater than 25.6 kHz. Its duration must be at least 3 rotations of the shaft. By default, this time signal is transferred with each SFI parameter. Since this signal is usually big, the System can be forced so that it is not transferred by MVX. This option is particularly useful when the MVX-NEST ANALYST communication speed has a very low baudrate. This option can be activated in the MVX properties: see § 5.11.3 .

Argument Values Threshold (number of shocks) Integer from 0 to 65536, default value = 10*

Observation period in number of measurement (OP)

Integer from 1 to 100, default value = 20*

(Ntot) Integer from 1 to OP, default value = 15*

Max number of successive exceptions

Integer from 1 to Ntot, default value = 10*

Signal to process Specifies measurement on to which processing is applied. You cannot define more than one SFI indicator on each time wave.

* Default values are an indication and must be adjusted to each machine behaviour.

The SFI result is a binary value: - The SFI is equal to 1 if the number of detected shocks is greater than the “Threshold” and if it is

repetitive over the “Observation period”. The repetitive pattern depends of the “Max total number of exceptions” and “Max number of successive exceptions”. Its status is “Alarm” (Yellow).

- The SFI is equal to 0 in all other cases and its status is “OK” (Green).

GCI (Gearbox Condition Index), indicator for the condition of gearbox (MVX, 14.12.KITE)

GCI is an indicator allowing MVX to be interfaced with a sensor for metallic debris (Metalscan by GASTOP). A metallic debris sensor is typically placed on the oil circuit of a gearbox, before the oil filter. Any metallic particle torn from inside the gear and circulating in the lubricating oil ends up passing through the debris sensor before being captured by the oil filter. The sensor only “sees” particles of a given size (about 200 µm and larger). Smaller particles are ignored. Schematically and given the presence of the oil filter, one can say that the sensor only sees each particle once. The parameters related to this indicator are created using the context menu:

Three parameters are created:

GCI-t: allows counting the cumulated number of particles as seen by the sensor GCI-h: allows monitoring the number of particles per hour. MVX updates this counter

every 5 mn. GCI-d: allows monitoring the number of particles per day. MVX updates this counter

every hour.

This type of parameter must be collected from a MVX channel of the “impulse counter” type : see § 5.11.4. The cumulative GCI-t parameter constantly counts the passing of particles as soon as the acquisition starts. In case the acquisition is stopped, the value of the counter is stored and will resume with the next MVX start It is possible to reset the counter value using the CAST tool.

BGI (Blade Guard Index), monitoring of wind turbine blades (MVX Prm) 14.13.

BGI (Blade Guard Index) is intended for the detection of structure resonance phenomena, in particular wind turbine blades. This indicator is to be used with a specific sensor, the principle of which is to deliver a signal proportional to the bending of the blade. The parameters relative to this indicator are created using the context menu:

New parameter / Vibration / Blade Guard Index (MVX)

Argument Values Analysis window (s) From 1s to 60s by steps of 1s; default value = 2s

High-pass filter (Hz) Programmable from 0.5Hz to 5Hz, default value = 2Hz

Trigger level (channel unit) From 0 to 10000, default value = 50 Reset level (MVX channel unit) From 0 to the trigger level, default value = 45

Result unit BGI. The result is a number of triggering.

Real-time monitoring Yes

The System monitors a sliding window with a length of « Analysis window ». The unbalance component is attenuated by the high-pass filter. The System counts the number of times the filter signals exceeds the trigger level. MVX will switch to alarm mode if this number is higher than the alarm threshold. This parameter can be collected on an IEPE or AC+DC MVX channel.

Kurtosis (MVP, Mvlg2*, MVX, KITE) 14.14.

This processing allows calculating the Kurtosis for the signal filtered by a band-pass filter. This indicator allows detecting the presence of shocks in the signal and is suitable for machines with slow rotation speeds. The Kurtosis processing is mathematically defined as the 4th-order centred moment of the time series. ONEPROD MVP and Mvlg2 also allow retrieving the RMS value of the filtered signal.

APPENDIX 4 – DEFINITION OF RELATIVE ALARMS 15.

Remark: relative alarms don’t take care of operating conditions.

History alarm 15.1.

This type of alarm is used to trigger an alarm if the difference between the current value (at instant t) and the previous value (at instant t-1) is greater than a fixed value expressed in %.

This type of threshold presents an alarm status called “ALARM” (yellow) if the difference is greater than the specified value.

Reference alarm 15.2.

This type of threshold triggers an alarm if the parameter current value is greater than its reference value times a multiplying coefficient (coeff.). Threshold = Ref. Val. * coeff.

The “Ref. Val.” value is measured or calculated at the reference date. The reference date is listed in the control date properties:

The reference date can be modified for the set of machines, the machine, the measurement point or the parameter. This type of threshold presents an alarm status called “ALARM” (yellow) if the parameter current value is greater than the parameter reference value times a user-defined multiplying coefficient (coeff= 1.5).

209

Brand of ACOEM

Statistical alarm 15.3.

This type of threshold triggers an alarm if the parameter current value is off a range centred on the average value of observed values since the reference measurement. The range corresponds to the standard deviation times a coefficient.

The last value along with all zero values is excluded from the average calculation. This type of threshold presents an alarm status “ALARM” (yellow) if:

σCoeffBμValue or σCoeffBμValue

with and representing the average value and the standard deviation of the value population since the reference date, respectively.

Predictive alarm 15.4.

This type of threshold is used to trigger an alarm if the progress slope is such that there is a risk of passing an absolute threshold (Alarm/Default or Danger/Incident) before the next control. The slope is calculated using regression. A regression calculation is performed. It starts from the most recent value of the parameter and goes back in time until one of these values is off an interval calculated from the standard deviation times a statistical coefficient. The resulting straight line is used to determine the predictive date from which the parameter will exceed the AL+ alarm threshold level. If this date falls before the next control (date of last control + normal monitoring period), then an alarm is issued.

APPENDIX 10 – “OPC-CLIENT” OPTION 21.

Principle 21.1.

This option can be used to retrieve information from different OPC servers belonging to the same local network as ONEPROD NEST ANALYST. This information is of the scalar type and is analysed by ONEPROD MVX or KITE Systems with its own measurements. OPC parameters can be used:

o Either as operating parameters used to determine the operating conditions of a machine o Or as monitoring parameters. A status change for an OPC monitoring parameter can allow

triggering an acquisition by ONEPROD MVX or KITE on all the signals and parameters of a machine (whether they are from OPC or MVX or KITE source), which will be stored in the NEST ANALYST database.

NOTE: This version of ONEPROD NEST ANALYST does not allow for the monitoring of purely-OPC equipment. ONEPROD MVX online monitoring must then be defined first before requesting any OPC information retrieval. In case of a communication failure with ONEPROD MVX, the OPC parameters will no longer be stored in ONEPROD NEST ANALYST and ONEPROD MVX or KITE will use the fallback condition. (see § 5.11.12.3).

Programming online “MVX-OPC” acquisition 21.2.

Configuration of MVX monitoring 21.2.1.

See Section 5.11

Configuration of OPC acquisition 21.2.2.

Once the ONEPROD MVX configuration is achieved, the associated OPC configuration requires the following additional operations:

Add an “OPC server” instrument

Select operating OPC items

Assign operating items to measurement points

Start mixed acquisition NOTE: These operations rely on the assumption that the equipment has already been associated with a ONEPROD MVX or KITE instrument to perform vibration measurements.

21.2.2.1.Adding an “OPC server” instrument

The OPC server is added from the context menu of the Instrument explorer:

Identification properties of the new OPC server must then be defined:

Name of computer: name of the PC network hosting the OPC server to address

219

Brand of ACOEM

Name of user: name of the user declared as having the executing rights on the addressed OPC server (see Installation guide) – CAUTION: in case of a domain installation, this username must be preceded by the domain name, e.g., “mvitech\ediag_admin”, where “mvitech” represents the name of the domain in which user “ediag_admin” was declared.

Password: password for account “ediag_admin” (or equivalent)

After entering this information, click on “Refresh” to see the list of OPC servers operating on the listed host machine. In the example below, only one OPC server is listed: “Matrikon.OPC.Simulation.1”. After selecting (checking) this server, validate the selection. At this time, ONEPROD NEST ANALYST will connect to the OPC server and extract all items available on this server. Server properties and items are then displayed in the properties window:

21.2.2.2.Selecting operating OPC items

The “Items” tab presents all items that can be consulted on this server. This list is limited to items of numerical and scalar type. Once selected, these items become “operating items” and are displayed in the Instrument explorer.

NOTE: Access to the items of an OPC server requires many precautions regarding access rights to COM/DCOM components used by this technology. Strictly adhere to the guidelines in the enclosed Installation Manual.

21.2.2.3.Assigning operating items to measurement points

Once operating items are identified, they must be assigned to the monitoring of a machine already monitored by ONEPROD MVX or KITE. To do so, connect these OPC items to one of the equipment measurement points.

Brand of ACOEM

The connection of an operating OPC item can be achieved:

either to a measurement point – in this case, an OPC parameter is automatically created, then associated with the operating item,

or directly to an existing OPC parameter, with which the operating item is then associated.

21.2.2.4.Starting the mixed acquisition

Once operating items are associated with the measurement point s of the machine to monitor, acquisition can be started from the context menu of the ONEPROD MVX instrument used for the monitoring:

NOTE: The « Start acquisition » function is available only in the context menu of a ONEPROD MVX instrument, OPC acquisition can only be performed as a complement to ONEPROD MVX vibration monitoring. When starting ONEPROD MVX acquisitions, acquisition commands are issued by ONEPROD NEST ANALYST to ONEPROD MVX, but also to the OPC server(s) useful for the monitoring of the same machines.

Limits of the OPC-Client function 21.3.

- One cannot use several OPC servers of a single editor (with the same CLSID). - The quality of an OPC item is converted into an ONEPROD NEST ANALYST status as follows:

o Good: “VALID” status o Bad, Uncertain, Out of Date: “INVALID” status

- The online monitoring of the equipment can use one or several OPC servers but absolutely requires an ONEPROD MVX instrument.

- OPC parameters of “Register” type are not taken into account. - The timestamping of OPC measurements transferred to ONEPROD NEST ANALYST corresponds to

the moment when ONEPROD MVX measurements are triggered and not to the real date originating from the OPC server.

- ONEPROD MVX uses the latest OPC information delivered by XCOM. The refreshment periodicity can be adjusted and must be greater than or equal to 1 second.

- In case of an aggravating status change, the « MVX channel only » capture mode is not handled if external OPC parameters are used by ONEPROD MVX. In this case, only the “Full equipment” mode works.

- In case of a network failure between ONEPROD MVX and the ONEPROD NEST ANALYST server (Xcom), no measurement will be transferred to NEST ANALYST, not even the OPC measurements that necessarily go through ONEPROD MVX. An event will inform the user of the communication failure.

APPENDIX 11 – “OPC-SERVER” OPTION 22.

Principle 22.1.

This option allows for the publishing of ONEPROD NEST ANALYST parameter values using a dedicated OPC server called “01dB.EDiagOPCServer DA Server V2.0”. For more information on OPC, consult http://www.opcfoundation.org.

Broadcast parameter by OPC 22.2.

OPC publishing can be done in three different ways:

At the Equipment level

At the Measurement Point level

At the Parameter level Publishing requires the Systematic use of the context menu associated with the published element and execution of the “Broadcast to OPC / Yes” function:

Each broadcasted parameter is highlighted in the configuration panel with a specific logo:

Rules:

Only operating or monitoring parameters can be published. Spectra and alarm statuses are not handled by this function.

OPC publishing relative to a piece of equipment comes down to publishing all its operating parameters, as well as all monitoring parameters defined for all measurement points.

OPC publishing relative to a measurement point comes down to publishing all monitoring parameters assigned to this point. Other elements are not published.

OPC publishing of an elementary parameter limits the publishing to this single element.

Publishing can be achieved equally on hard or soft parameters

Publishing selections made in ONEPROD NEST ANALYST are immediately taken into account by the OPC server associated with NEST ANALYST.

OPC data are updated at each new measurement date stored in ONEPROD NEST ANALYST data base. Publishing functions applied at the Equipment Explorer level are fully recursive: publishing a machine will automatically publish all associated sub-locations and sub-equipment. To stop a publishing process, use the « OPC Publishing/ No » function, which is directly accessible from the contest menus of published elements. Stopping all OPC publishing for a local database can be done instantly by calling the “OPC Publishing / No” function by pointing to the “Production assets” node in the Equipment Explorer.

Consultation of published OPC data 22.3.

Published ONEPROD NEST ANALYST parameters can be consulted from any compatible OPC client application. Example of consultation with the “Kassl” OPC explorer available in Cd5XprTools\Tools\OPC:

After selecting the “01dB.EDiagOPCServer DA Server V2.0” server, select OPC items to consult:

225

Brand of ACOEM

Once selected, these parameters must be assigned to the “Default“ group:

For each parameter, the following information is available in “real time”:

name

quality

date

value

alarm status (PStatus)* For each machine, one can then consult in « real time »:

the general Process & Vibration status for the machine (EVStatus)*

the expert advice (EAdvice)**

the Oil alarm status for the machine (EOStatus)* * Alarm statuses are coded as follows: OK=1, pAl=2, Al=3, Dg=4 ** Pieces of advice are coded as follows: Excellent=1, Good=2, Fair=3, Critical=4

Kassl also allows for a graphic representation of the time history of these parameters: NOTE: In case of an update of published parameters by ONEPROD NEST ANALYST, Kassl may no longer be able to display requested items. The following message may then be displayed:

226

Brand of ACOEM

In this case, one should relog on to ONEPROD NEST ANALYST’s OPC server and select the items to display once again.

Limits of the OPC-Server function 22.4.

- If production assets / equipment / (measurement point / Monitoring parameter) are renamed,

previously published OPC parameters will not take into account the update and keep their former name. One must then cancel and repeat the OPC publishing.

- The OPC EDIAG server cannot be connected to a ONEPROD MVX instrument.
