Chapter 2

System Hardware

The PCU-100 is a versatile unit which connects to a broad family of sensors. Afterassessing the monitoring needs of the plant, each PCU unit can be factory-customized and shipped with the required hardware in the form of task modules. Theuser then uses the front panel keypad to configure the new modules according to hisown specifications and preferences and switch to on-line monitoring. Real-time alarmreporting is done through front panel LEDs while on-board relays are tripped forannunciation by field equipment. Measurement readout uses the two-line VFDdisplay. The user may also choose to route raw or processed information to third-party analog display units by way of the front-panel BNC connectors or to interfacethe PCU with the ZOOM monitoring system through RS-485 communication.

This chapter is pivotal to adequate operation of the PCU-100 unit. It is divided intofour sections:

Section I: System Parts and Controls identifies and briefly describes all user-accessible parts and controls found on both front and rear panels as well as on theinternal circuit board which hosts the task modules.

Section II: Using Task Modules surveys the various task modules available andelaborates on the mix and match possibilities that best suit practical monitoring andprotection applications. Installation procedures as well as field wiring diagrams arealso included for each task module.

Section III: Electrical Supply focuses on the power supply and instructs users how toprovide adequate power to the PCU unit in regards to worldwide use.

Section IV: The Communication Interface discusses the communication interfaceoption available for all PCU units equipped with system software v. 1.40 and later.

Note: Configuration and operation of the PCU-100 software are the subject ofChapter III entitled: The User Interface.

1Alarm Annunciation LED Array (1 to 4)

A set of four ALARM LEDs are located left of the VFD screen. Each LEDprovides instant visual notification upon violation of preset alarm thresholds onprocessed signals such as “raw”, “DC”, “AC”, “average”, “RMS”, “peak”,“maximum value” (Smax), “resultant vector” (Svector), airgap or peak-to-peakprocessed signals, via programming of the PCU software. As will be explainedlater on in Chapter III, use of the voting logic feature allows multiple systemevents to be routed to the same LED with event identification shown on the VFDscreen.

Alarm LEDs are three-color indicators. Reported conditions include: Green =no alarm, Orange = Alert threshold, Red = Danger threshold. Note that you maypress Cancel + Enter simultaneously to test this feature.

2Vacuum Fluorescent Display (VFD)

As the name implies, this button is used to disregard the registering or enablingaction you are about to take on the displayed selection. Click to cancel an actionor hold down at least 1 second to move back, one sub-menu at a time.

You may also press Cancel + Enter simultaneously to enable test mode. Usethis feature to test the front panel ALARM and OK LEDs. In test mode,ALARM and OK LEDs go dark, then blink green, orange and red successivelyfollowed by a short beep.

9Menu Button

This pushbutton gives access to the PCU configuration menu at all times. Use itto access the main system menu once the unit has gone through its power-upsequence or to toggle between bargraph display and menu during on-linemonitoring in order to review configuration attributes.

aJOK LED Array (1 to 4)

The four LEDs mounted above the PCMCIA card slot, labeled "OK", are used toconfirm the integrity of the vibration input channels in use.

Typically, if the monitoring system connects one to four inputs, then assign aLED to each input for simultaneous “status OK” reporting on each channel.However, if the system uses five to eight inputs, then apply voting logic so thatall inputs are accounted for. In this scheme, inputs are grouped in pairs and eachpair is assigned to a LED. A pair usually consists of two input channels of asingle vibration input module. As will be explained later in Chapter III, thesoftware is then programmed to report faults if one of two channels is faulty or ifboth channels are faulty, with channel ID displayed on the VFD screen.

In either case, a status OK LED validates the integrity of the measuring chain(sensor-cable) which measures the vibration signal responsible for the alarmcondition reported by a corresponding alarm LED. By default, OK LED 1 isused in conjunction with ALARM LED 1 and so on. OK LEDs remain ON atall times. Status is revealed by a change in color: Green = value in range (StatusOK), Red = faulty channel or value out or range (Status not OK). Note that youmay press Cancel + Enter simultaneously to test this feature.

aAPCMCIA card Slot

The PCMCIA card slot is designed to accept PCMCIA cards of type I, II and III,with or without adapters. Consult Chapter IV: Technical Specifications, for alist of the cards that fully meet the requirements for this application.

The PCMCIA card slot serves two main purposes. First, it allows the entiresystem configuration to be conveniently saved on a compact flash memory card.The card can then be stored for security reasons or carried over to another PCU-100 unit for instant cloning provided the two PCU units have the same taskmodule assignments. Storable user configuration parameters include:

• vibration input settings• alarm threshold settings• ALARM and OK LED assignments• process selection and configuration• internal and external relay selections• bargraph settings


PCMCIA slots are also provided to allow field upgrade of the system software.VibroSystM will inform clients of new releases as they become available. Otherapplications that will take advantage of this interface are also planned.

When inserting a card, press gently to snap into position. Release card bypressing the eject button. The activity LED located next to the eject lever lightswhen a card is inserted. Consult Chapter III: The User Interface to learn how toaccess the system software in order to download or upload software.

2.2: Using Task Modules

2.2.1: OverviewThe PCU-100 is a CPU-based data processing unit which employs a combination oftasks modules to carry out a wide range of applications in real-time. Task modulesare compact electronic cards with edge-of-card pin connectors designed toaccomplish dedicated tasks. They include:

• the vibration input module: a two-channel electronic module whichcan be adapted to meet the specific input characteristics of the inputdevices (sensors or transducers) used to measure such parameters asdisplacement, acceleration and velocity.

• the processing and analog output module: as the name implies, thismodule features the digital signal processing (DSP) circuitryresponsible for managing the processes performed in real-time mode onup to four vibration input channels simultaneously. In addition to theinformation displayed on the VFD screen during monitoring, thismodule outputs processed information which can be sent to the ZOOMmonitoring system by way of an optional RS-485 communicationinterface, or to portable metering instrumentation connected to rear-panel I/O ports.

• the internal relay module: similar in appearance to other task modules,this module features three relay outputs. Each relay is intended foractivation of external annunciation devices so as to notify of systemevents such as alarm threshold violation on selected processes, failureof any vibration input channel (Status not OK) or a combination ofevents through the application of voting logic.

• the external relay card with internal relay driver module: this is a1-U high version of the internal relay module with nine relay outputs ona standalone unit. This allows for extensive system event annunciationwith device switching upon violation of user set thresholds onprocessed signals, failure of vibration input channels (Status not OK) ora wide combination of events through voting logic. Use of the externalrelay card requires that a relay driver module be installed onboard thePCU to allow configuration and operation via the PCU software.

• the digital I/O and 1/rev module: Digital inputs are supplied to allowremote control of features such as rack inhibit, alarm reset, dangerbypass and power-up inhibit. As well, digital outputs are provided forremote annunciation of system-wide statuses such as OK system,power-on, power low and rack bypass. Refer to page 2.30 for furtherdiscussion on digital inputs and outputs. This task module is also usedfor acquisition of the one-per-revolution (1/rev) pulse from asynchronization probe or other data acquisition unit connected to theprobe and output to the next PCU unit (if required).

As will be discussed further on page 2.27, the vibration input modulemakes use of the 1/rev signal for Svector display on an oscilloscope.

Each task module will be reviewed individually in the next sections, complete withinstallation tips and procedures with clear terminal wiring diagrams.


By incorporating task modules into a modular design, the central processor can focuson software operations, data routing, alarm management, display and communication.The CPU centers around an Intel microprocessor running under MS-DOS allowingconnectivity to conventional PC hardware. This allows PCU units to communicateamong themselves as well as with AGMS and ZOOM acquisition units.

Using task modules requires a thorough understanding of your monitoring andprotection needs. Your planning must account for the actual number of sensors andthe number of protection relays per input or processed signal. Since the PCU unit isfully programmable and extensively customizable, you must mix and match moduleskeeping in mind the requirements and limitations one module sets on other modules.

As discussed in the next paragraphs, many system upgrades can be performed in thefield. Remember however that each task module must be given a specific busaddress through factory-set address DIP switches. The “bus” represents a chainscanned by the system software and each module represents a link in this chain

It is therefore expected that the user be able to provide VibroSystM with a clearlayout of the current configuration when ordering extra modules. This requirementwill allow VSM to properly set the new modules before shipment and thus preventconflicts with preinstalled modules.

Table 2.1 summarizes typical module combinations with respect to the followingcriteria:

• each PCU unit features 8 expansion slots for up to 8 task modules;

• one digital I/O and 1/rev module is needed for capture of the 1/revsignal required in some applications;

• use of an external relay card requires that an internal relay drivermodule occupy one expansion slot;

• one processing and analog output module is required for each set offour input channels;

• depending on the type of data requested and the extent of machineprotection, the number of vibration input signals may differ from thenumber of available processed analog outputs.

Note that this example makes use of the PCS-10x sensor at the front-end of themeasuring chain.

2.2.2: The Vibration Input ModuleAs the name implies, the vibration input module is the point of entry of all sensorsignals into the PCU-100 system. This task module is a dual-channel electronic cardcapable of acquiring and filtering the raw vibration measurement signal collectedfrom a variety of sensing devices. Each module is factory-configured to thecustomer’s requirements for one of the following input sources:

• PCS-series proximity sensors – raw vibration-to-frequency, inputmodule range between 85 kHz to 155 kHz;

• FOA-100 fiber-optic accelerometer – MODE 1 (wide) rawacceleration-to-velocity, input sensitivity: 0.1V/g, maximum input30 gpeak, velocity range 585 mm/s, output ±10V;

• FOA-100 fiber-optic accelerometer – MODE 1I (narrow) rawacceleration-to-velocity, input sensitivity: 0.1V/g, maximum input12 gpeak, velocity range 234 mm/s, output ±10V;

• velocity transducer with bloc conditioner – conditioned velocity-to-voltage, input module range of 0 to -20 V;

• Wilcoxon 797L piezoelectric accelerometer – acceleration-to-voltage:input module range 9 VDC, 17.6 mV peak or 0.035 g; minimumcalibration:0.8 Hz (0dB), 0.16 Hz (3 dB);

• Wilcoxon 797V velocimeter – conditioned velocity-to-voltage, inputrange 8 to 12 VDC, 3.94 mV/mm/sec sensitivity;

• Eddy current proximity transducers with bloc conditioner –conditioned vibration-to-voltage, input module range of 0 to -20 V;

• piezoresistive accelerometer with built-in conditioner – conditionedacceleration-to-current, input module range 0 to 20 mA;

• VM-series air gap sensors with conditioning module – conditioneddisplacement-to-current, input module range 4 to 20 mA.

Regardless of the type of input signal it receives, the vibration input moduleaccomplishes three basic functions.

• First, it collects, at a rate of 4 065 samples/second, the raw or pre-conditioned sensor signals on two separate channels. Signals are thenfiltered and linearized before they are sent to the processing and analogoutput module.

• Second, it generates a linearized 0 to ±20 V dynamic vibration outputavailable to metering equipment through rear-panel I/O ports or front-panel BNC connectors.

• Finally, it serves as a power source rated at a max. 24 V, 15 mA forboth sensor and conditioner (when applicable). This feature isparticularly useful when connecting to unibody accelerometers.

Considering that all configurations of the module basically perform the same tasks,we will limit ourselves to describing the most commonly used in PCU-100 basedapplications: the relative vibration input module which receives the frequency signaltransmitted by the PCS vibration sensor.

Figure 2.2 illustrates a typical PCS measuring chain. Note that this scheme does notrequire that a conditioning unit or probe driver be inserted between the sensor and theinput module.

Figure 2.2: The PCS-102 measuring chain. The raw vibration information takes the form ofa frequency signal acquired and linearized by the vibration input module. The optionaltapping box extends the range of the sensor's integral cable (either 5, 10 or 15 meters) tomore than 300 meters.

In all cases, the digitally linearized signal is sent to the processing and analog outputmodule for processing and comparison to alarm thresholds for machine protection.The linearized – or raw vibration – signal is also available for user equipment such asvibration meters or oscilloscopes with output levels of -2 to -18V on terminals 6 and7 of the rear panel I/O port assigned to the vibration input module. See Figures 2.4to 2.10 for a complete rundown of I/O port terminal assignment. Front panel BNCconnectors are also provided for capture of the linearized signals by user meteringequipment.

2.2.2.1: Installation and WiringPCU-100 units are shipped fully configured with all specified task modules installed.However if your monitoring or protection needs grow, you can upgrade your existingequipment in the field by adding one or many vibration input modules Whenassessing your needs, consult Table 2.1 to find out if they meet the PCU unit's taskmodule integration capacity. Then contact your local VibroSystM representative sothat the new modules be factory-set to prevent conflicts.

Proceed as follows to install new vibration input modules:

1. Power OFF the unit and remove from rack.

2. Remove top cover by unscrewing the six hex-socket set screws. Thiswill reveal the circuit board and power supply unit. Locate theexpansion bay on the circuit board (see Figure 1 early in this chapter forlocation and identification of parts).

3. Before unpacking the new vibration input module, you must removeany static electricity buildup from your skin. Do so by touching anyconductive material put to ground such as a water pipe.

4. Grab the new task module by the edges and precisely align both pinarrays with corresponding socket strip on the expansion slot. Gentlypress until module is firmly in position.

5. Run one end of the supplied flat cable to the 12-pin strip connectorfound on the back of the task module. Notice the plastic guidemoldings on each connector which prevent reverse connection.

6. Connect the other end of the supplied flat cable to the correspondingI/O port. It consists in a 12-pin strip found on the inner-back panelUse top or bottom pin strips only. Make sure to match the slot number(PO1, PO2, …) printed on the circuit board to that of the inner backpanel (see Figure 2.3).


7. Notice two pairs of twisted black/red wires terminated with connectors.Match each connector with the 12-pin strip as shown next. Each pairbrings the raw signal from both vibration channels to the front-panelBNC connectors. See earlier in this chapter for BNC connectorassignment.

Once module installation is complete, connect the leads of the extension cablecoming from the sensor to the rear panel I/O port. Proceed as follows:

1. Remove the female terminal adapter from its rear panel I/O port.

2. If you are connecting PCS sensors, simply match each color-coded wirefrom the extension cable to the corresponding terminal socket withrespect to terminal assignments identified in Figure 2.4. Insert the crimpcontacts firmly before screwing to prevent wires from pulling out overtime.

3. If you are connecting FOA-100 accelerometers, match two of the threecolor-coded wires from the extension cable to the correspondingterminal socket with respect to terminal assignments identified inFigure 2.5. Pay attention to the use of a dedicated power supply to drivethe accelerometer circuitry with +24VDC, 40 mA. Do not run powerwire directly to the I/O port terminals as this would trip offprotection fuses on the vibration input module.

Figures 2.4 to 2.10 provide generic terminal assignments suitable for a wide range ofthird party sensors and transducers.

Caution: Always use extreme caution when wiring peripheral devices.Beforehand, always make sure to carefully read the manufacturer’s documentationfor proper sensor and/or conditioning unit hookup. Failure to do so might damagethe sensitive electronics of either vibration input module or conditioner upon power-up of the PCU unit.

Always power-off and disconnect the PCU-100 unit before making connections.

You may now power ON the system and access the software in order to enable thevibration input module and to set various monitoring attributes.


2.2.3: The Processing and Analog Output ModuleThis module is central to the PCU-100's ability to perform real-time processing onsensor signals. As well, it manages comparison to alarm thresholds to providemachine protection. The processing and analog output module accepts signals fromup to four sensor input channels for processing, and generates four analog signalsthrough rear-panel I/O port connectors. Refer to Figure 2.11 for a functional diagramof the PCU task modules.

Keep in mind that the number of output channels (four) is independent from thenumber of input channels (up to four). For example, a single input channel could beused to generate four different calculations, thus providing four analog outputs.

The primary purpose of this module is to submit the raw sensor signal to one of manyprocesses requested by the user. See Appendix B: Process Overview for a overviewof each process broken down into its mathematical components. Aside from sitespecific variables that can be programmed into the system using the front panelkeypad, all formulas and most default values are preloaded in the operating software.In monitoring mode, real-time acquisition and computation provide valuable insightinto the monitored machine's behavior.

In addition to the raw filtered signal output delivered by the vibration input moduleoutput terminals, the selectable calculations performed on the vibration signal includeAC/DC values, RMS, peak, peak-to-peak, average and airgap readings on individualinput channels, and the maximum value also referred to as Smax. Consult Chapter III:The User Interface to learn how to configure this module and select processes forcontinuous on-line monitoring. The graph shown in Figure 2.12 identifies keyprocessed components of the input vibration signal.

Process information can be handled in various ways. First, it can be viewed on theVFD screen through bar graph or numerical readings. Second, readings can becompared with user-set dual alarm thresholds for real-time machine protection. Here,the lower priority alarm threshold indicates an Alert condition while the higherpriority threshold indicates a Danger condition. The latter may prompt immediateaction: such as a machine shutdown. In addition, processed information is availablein analog format to field measuring equipment connected to the rear panel I/O port.

As will be discussed later in paragraph 2.4: The ICRS-485 Communication Interface,on page 2.39, users of VibroSystM’s ZOOM monitoring system can add acommunication interface to the PCU-100 unit and integrate it into their network ofextensions. In the ZOOM environment, selected processes from the PCU becomepart of the power station configuration as status parameter inputs configurable usingZOOM Configuration. These inputs provide further insight into overall machinecondition by way of correlations with other parameters such as air gap.

In short, the PCU software holds provision for two alarm threshold settings (Alertand Danger) for each process identified earlier. Furthermore, convenient Status OKLEDs report the integrity of the measuring chains which provide the rawmeasurement at the root of reported alarms. As will be discussed in the softwaresection, the OK feature warns the system operator of any failure of the measuringchain which could invalidate the processed information. As such, this featuresafeguards against falsely triggered alarm.


2.2.3.1: Installation and WiringPCU-100 units are shipped fully configured with all specified task modules installed.However, as your monitoring requirements grow, you may need to install additionalsensors, vibration input modules and ultimately add an extra processing and analogoutput module. When considering your options, consult Table 2.1 as a generalguideline, to find out if they meet the PCU unit's task module integration capacity.

Proceed as follows to install a new processing and analog output module:

1. Power OFF the unit and unmount from rack.

2. Remove top cover by unscrewing the six hex-socket set screws. Thiswill reveal the circuit board and power supply unit. Locate theexpansion bay on the circuit board (see Figure 1 early in this chapter foridentification and location of parts).

3. Before unpacking the new processing and analog output module, youmust remove any static electricity buildup from your skin. Do so bytouching any conductive material put to ground such as a water pipe.

4. Grab the new processing and analog output module by the edges andprecisely align both pin arrays with corresponding socket strip on theexpansion slot. Gently press until module is firmly in position.


6. Connect the other end of the supplied flat cable to the correspondingI/O port. It is a 12-pin strip found on the inner-back panel Use top orbottom pin strips only. Match the slot number (PO1, PO2, …) printedon the circuit board to that of the inner back panel (see Figure 2.13).

Once the processing and analog output module has been properly installed, you mayrefer to the rear panel terminal assignment chart (Figure 2.14) for connection ofexternal user equipment. Proceed as follows for rear panel connections:

1. Remove the proper female terminal adapter from the rear panel I/O port.

2. Use skinned wires only and match with screw-type terminals of theappropriate output channel. The following illustration shows a terminaladapter in the upright position with channels labeled #1, #2, #3 and #4from top to bottom.

3. Once wiring is complete, run screw terminal adapter through the back ofthe rack assembly if necessary and secure connection to the rear panelbefore mounting the PCU unit.

You may now power ON the system and access the software in order to enable thenew module and set various signal processing attributes.

2.2.3.2: Alarm NotificationThe processing and analog output module performs comparison of monitored valuesto user-set alarm thresholds. Monitored values are dependent of the process selected:Raw, AC/DC, RMS, Peak, Peak-to-peak, Average Maximum (Smax) and Airgap.

With the exception of the airgap value process, all alarms are triggered when resultvalues increase up to the point where they violate thresholds. As for the air gapvalues, an alarm will be reached when values decrease to critical gap levels.

In monitoring mode, users are notified of alarms – threshold violations – by way ofthe four front panel tri-color ALARM LEDs. Four dual-color OK LEDs are providedas well. Each OK LED matches an alarm LED and warns of faults (status not OK) onthe measuring chain linked to the process generating the alarm. A fault reported byan OK LED will invalidate any alarm originating from the faulty measuring chain.

Caution: Do not attempt to configure status OK LEDs for input channelsconnected to MONITRAN or WILCOXON accelerometers and velocity transducers.The design of these devices does not permit reliable use of the status OK feature.


The software typically assigns two alarm thresholds – Alert and Danger – perprocessed signal at one time. Thresholds are usually programmed in the systembefore unit shipment and are reported as follows:

• Alarm LEDs remain ON at all times. They glow Green for as long asreadings remain in the "safe" area of the measuring range.

• Alarm LEDs turn Orange if output values equal or exceed the loweralarm threshold (Alert) set via the PCU software.

• Alarm LEDs turn Red if output values reach the higher alarmthreshold (or Danger level) set via the PCU software.

• OK LEDs remain ON at all times. They shine Green for as long as nofailure of the measuring chain is reported.

• OK LEDs turn Red if measuring chains fail. An example of this wouldbe a broken extension cable. Such an indication would invalidate alarmconditions reported simultaneously by the associated alarm LEDs.

As discussed on page 2.30, a digital input can be assigned to remote thresholdselection, a feature which allows users to toggle between two threshold sets.

Notice to Users of the ZOOM system

PCU-100 units connected to the ZOOM monitoring system through RS-485communication behave like STATE extensions. Therefore, when registeringthe new inputs in your station configuration, set the alarm threshold valuesusing ZOOM Configuration’s Edit input window. Alarm threshold values areprinted in the Configuration Report issued for each PCU-100 unit shipped.Alarm threshold values can also be displayed on the VFD screen when thePCU-100 is in monitoring mode. To view these values, simply toggle betweenbargraph headers using the U and V scroll buttons. See paragraph 3.1.11:Bargraph and Alarm Acknowledgement, to learn how to consult bargraph headers.

The PCU unit complements your annunciation system or other active safety measuresby managing device switching upon alarms reported on any or all of the raw orprocessed data channels. For that purpose, two types of relay modules are available.Relay modules will be discussed further in the next two paragraphs.


2.2.4: The Internal Relay ModuleAs the name implies, the internal relay module is a typical task module which fits anyavailable expansion slot. This module features three miniature dry-contact double-pole-single-throw (DPST) relays for safety device control on any combination ofalarm and OK signals.

Figure 2.15 shows relay contact status in standby mode, that is, during normaloperation of the PCU, when no alarms are reported. It indicates field switchingcombinations achieved when both normally closed and normally open contacts areused simultaneously. Each relay circuit can handle loads up to 150VDC at 0.4 A or120/220 VAC (50/60 Hz) at 2A.

During normal operation, each relay is maintained de-energized. Refer to paragraph3.2.5: Internal Relay Module and External Relay Card Unit in Chapter 3 to learnhow to customize this feature. As soon as an alarm is reported on the user-assignedchannel, the relay is energized causing device switching. When planning switchingequipment wiring, consult Figure 2.17 to determine whether Normally Open (NC) orNormally Closed (NC) terminals better suit your protection needs. Since each relaychannel maintains closed contacts at all times, always remember that NC andNO refer ONLY to the condition of the relay while the unit is on-line with noalarm condition reported.


2.2.4.1: Installation and WiringPCU-100 units are shipped fully configured with all specified task modules installed.However your system can be easily upgraded for basic machine protection byinstalling an internal relay module. When assessing your protection needs, consultTable 2.1 to find out if they meet the PCU unit's task module integration capacity.

Proceed as follows to install the new internal relay module:


2. Remove top cover by unscrewing the six hex-socket set screws. Locatethe expansion bay on the circuit board (see Figure 1 early in thischapter for identification and location of parts).

3. Before unpacking the new internal relay module, you must remove anystatic electricity buildup from your skin. Do so by touching anyconductive material put to ground such as a water pipe.

4. Grab the new task module by the edges and precisely align both pinarrays with corresponding socket strip on the expansion slot. Gentlypress until module is firmly in position.


6. Connect the other end of the supplied flat cable to the correspondingI/O port. It consists in a 12-pin strip found on the inner-back panel.Since internal relay modules are usually last to be added, look for PO2or PO1 markings. Use top or bottom pin strips only. Make sure tomatch the slot number (PO1, PO2, …) printed on the circuit board tothat of the inner back panel (see Figure 2.16).

1. Pull out the female terminal adapter from the rear panel I/O port.

2. Use skinned wires and match with screw terminals of the appropriaterelay channel. As shown next, with terminal adapter in the uprightposition, channels are labeled #1, #2, and #3 from top to bottom. Twocontacts per channel are normally open and two for normally closed.

You may now power ON the system and access the software to match the various rawor processed outputs with individual relays.

2.2.5: The Internal Relay Driver Module withExternal Relay CardFor extensive protection over many outputs, the external relay card features nineminiature dry-contact double-pole-double-throw (DPDT) relays for device switchingon any combination of alarm, status OK and system OK signals.

The external relay card is a rack-mount 1U (3.75") high panel featuring nine LEDsand relays. A relay driver module occupies an expansion slot inside the PCU unit. A1 meter (3 feet) 12-pin cable running from the corresponding I/O port on the backpanel of the PCU to the relay card's back panel input port connects the two units.

Figure 2.18 illustrates front and back panel. Each of the nine tri-color LEDs iscoupled to a relay port. LEDs change color to reflect the status of the relay channel:

Color Reported Status

Green system on-line, relay de-energized, no alarm signal

Red system on-line, relay energized on alarm signal

Amber system on-line, mechanical problem encountered


Similar in principle to the basic three-channel internal relay module, the externalrelay card holds 9 relays. Each relay channel supports device switching on anycondition whose status change is reported by the PCU system. Conditions include:

• Power ON,• Power Low,• Alert threshold violations on selected processes,• Danger threshold violations on selected processes,• Status OK on selected processes,• System OK.

Consult Figure 2.21 to determine between the twosets of Normally Open (NC) and Normally Closed (NC) terminals, the combinationthat suits your protection needs for each relay channel. Since several contacts areclosed at all times, always remember that NC and NO refer ONLY to thecondition of the relay while the unit is on-line with no alarm condition reported.


2.2.5.1: Installation and WiringPCU-100 units are shipped fully configured with all specified task modules installed.However if your installation requires extensive protection, you may upgrade to fullrelay capacity by installing an internal relay driver module with external relay cardunit. When assessing your protection needs, consult Table 2.1 to find out if theymeet the PCU unit's task module integration capacity.

Installation of the task module and external card unit is done in three steps. First, theinternal relay driver module must be installed inside the PCU unit; which is thenconnected to the external relay card unit and finally field (user) equipment must bewired to the external relay card unit's back panel I/O port.

Step One:

Proceed as follows to install the internal relay driver module:

1. Power OFF the PCU unit and unmount from rack.

2. Remove top cover by unscrewing the six hex-socket set screws. Thiswill reveal the circuit board and power supply unit. Locate theexpansion bay on the circuit board (see Figure 1 early in this chapter foridentification and location of parts).

3. Before unpacking the new internal relay driver module, you mustremove any static electricity buildup from your skin. Do so by touchingany conductive material put to ground such as a water pipe.

4. Grab the internal relay driver module by the edges and precisely alignboth pin arrays with corresponding socket strip on the expansion slot.Gently press until module is firmly in position.


6. Connect the other end of the supplied flat cable to the correspondingI/O port. It consists in a 12-pin strip found on the inner-back panel.Since the internal relay driver module is usually last to be added, lookfor PO2 or PO1 markings. Use top or bottom pin strips only. Makesure to match the slot number (PO1, PO2, …) printed on the circuitboard with that of the inner back panel (see Figure 2.20).

Figure 2.20: View of the PO1 and PO2 I/O ports normally used by the internal relay drivermodule, as seen from inside the cabinet.


Step Two:

1. Once you have properly installed the internal relay driver module, youmay proceed with connection to the external relay card unit. To do so:simply grab the interface cord and connect one end to the designatedI/O port on the PCU-100 unit.

2. Connect the other end of the interface cord to the input port connectorlocated on the extreme right of the relay unit's back panel.

Step Three:

After performing system connections, you should proceed with wiring of the fieldswitching devices to the external relay card unit. Refer to the rear panel terminalassignment chart illustrated in Figure 2.21. Note that the terminal assignmentslisted next applies while the relay is de-energized.

Proceed as follows to make connections:

1. Remove each 6-terminal female adapter from the rear panel I/O ports.

2. Use skinned wires only and match with screw-type terminals of theappropriate external relay channel. Two contacts per channel arereserved for normally open and two for normally closed switches.

Note 1: Remember that the term normally (open or closed) refers to thecondition of the relay while the PCU unit is on-line with noalarm reported.

Note 2: Relays of the external card unit are maintained de-energizedduring normal operation. This setting can not be defeated.

You may now power ON the system and access the software in order to match thevarious raw or processed outputs with individual relays.


2.2.6: The Digital I/O and 1/rev ModuleThis module equips PCU-100 units connected to proximity measurement sensors. Itsmain purpose is to receive the one-per-revolution pulse (also known as thesynchronization signal) from VibroSystM's synchronization probe facing the shaft ofthe monitored machine. The synchronization signal can then be used in twoapplications: shaft displacement monitoring and air gap protection.

2.2.6.1: The Synchronization Signala) Shaft displacement monitoring

To perform shaft displacement monitoring, the vibration input module combines thesynchronization pulse with X- and Y-axis vibration readings which allows the user todetermine angular positions along the rotating axis of the monitored machine. Theangular position used to determine the area of resultant vector is revealed by the factthat a synchronization pulse is emitted after one machine rotation, or every 360°.

For this purpose, individual sensorsconnected to input channel 1 and input channel 2 of the vibration input module facethe generator shaft at X and Y positions relative to each other (see Figure 2.22).

Note: This application requires that you access the configuration software to assignanalog outputs to the 1/REV pulse and Svector signals and that you connect youroscilloscope to the matching rear-panel I/O port. See paragraph 3.2.3 for more onassigning analog outputs.

Every peak shown in Figure 2.23 represents the resultant shaft displacement vector(or Svector), with each machine rotation. Correlating a peak along the synchronizationsignal real timeline reveals the area of maximum displacement.

b) Air gap protection

For this application, the PCU-100 unit inspects measurements from air gap sensors“looking” at the passing poles of a rotating machine. They include VibroSystM’sVM family of capacitive air gap sensors. The need to inspect air gap comes from thefact that a large rotating machine is subject to large stress which influences the airgap between rotor and stator.

A measured air gap value that equals or falls below the alarm thresholds set by theuser based on machine design specifications is considered preoccupying. However,the same value will trigger an alarm if it repeats over several rotations. The numberof rotations revealed by the synchronization pulse determines the delay during whichvalues are registered and compared before they can be reported by the unit in theform of an alarm.

The ZOOM system goesbeyond air gap protection byproviding a full complementof monitoring and diagnostictools over many machinecritical parameters.

In instances where VibroSystM’s ZOOM system is in use, the PCU unit does notneed to connect directly to the synchronization probe. Instead, the unit receives thesignal from the AGMS or ZOOM acquisition unit connected to the probe. Refer tothe AGMS and ZOOM 2000 Hardware User's Manual for connections to theacquisition units. Once acquired, the signal may be routed to other compatibleequipment, such as slave PCU units, via terminals of the dedicated rear panel I/Oport.

The synchronization probe consists of a proximity switch. This switch is basically anopen-collector transistor that conducts when the target on the generator shaft passesin front of it. See Figure 2.25 for an illustration of the capture sequence.

An interrupt signal is generated on the CPU with every 1/rev pulse. The interruptthen associates the pulse with the data just processed.

2.2.6.2: Digital inputs and OutputsIn addition to acquiring the 1/rev pulse, this task module hosts sets of digital inputsand outputs, making the PCU-100 fully API 6701 compliant.

Digital inputs are provided for control of several system features by a remoteswitching device. Once enabled using the configuration software, the task moduleresponds to a +5V drive signal from remote relay contact closure which causesindividual inputs to change logic status (0 to 1). In turn, this change activates one ormany of the system features described next.

• Rack Inhibit: upon remote contact closure, this feature disables allAlert and Danger alarms. As well, it enables the rack bypass outputfeature for use on other PCU units.

• Alarm Reset: upon remote contact closure, this feature resets latchingalarms. Enable this feature if you want to reset latching alarmstriggered by the PCU-100 quickly without having to access the alarmacknowledgment screens or to power down the unit.

• Danger Bypass: upon remote contact closure, this feature inhibitstriggering of Danger alarms. This feature is especially useful if yourgenerator is set to shut down on Danger-threshold alarms. You maytherefore perform maintenance on the PCU, measuring chains or otherfield wiring without risk of activating the Danger relays.

• Power-Up Inhibit: upon remote contact closure, this feature disablesall Alert and Danger alarms.

1 The American Petroleum Institute, a division of the American National Standards Institute. The API 670 sets therequirements for vibration, axial position, and bearing temperature monitoring systems.


• Threshold Set Selection: upon remote contact closure, the systemsoftware is instructed to switch between two sets of alarm thresholds.Typically, a logic status of 1 would correspond to the higher thresholdset while a logic status of 0 would correspond to the lower settings.This feature is particularly handy when you wish to prevent triggeringof alarms at times when vibration is expected to be significantly higher.Such is the case during machine startup and shutdown. The principle ofthreshold set selection is illustrated in Figure 2.26.

Threshold set no. 1:select this set when machineoperates at full load.Threshold points are setaccording to designspecifications.

Figure 2.26: Illustrating threshold sets along the sensor’s measuring range..

In addition to the digital inputs, up to three digital outputs can be usedsimultaneously. For example, outputs can be enabled to keep the indicator paneloperator informed on system events such as power-ON/Power Low, System OK andRack bypass. System event selection will be reviewed later in paragraph 3.2.6:Configuration of the Logic Parameters.

To trigger the digital outputs, the task module sends a +5V drive signal which is fullycompatible with the digital input side of any digital I/O and 1/rev module installed inanother PCU unit in the facility. You may therefore use the Power ON feature topower ON/OFF a slave PCU unit in a master-slave configuration.

Figure 2.27: Customizing the Digital Input/Output and Synchronization Module for plantoperation

Refer to Figure 2.29 for detailed connections to peripheral input and output devices.

2.2.6.3: Digital I/O and Synchronization Module Installationand WiringPCU-100 units are shipped fully configured with all specified task modules installed.However if you wish to add or replace a digital I/O and 1/rev module, consult thefollowing to ensure that connection to the new module are performed according todesign specifications. Note that each PCU accepts one digital I/O and 1/rev module.Installation of the optional synchronization probe will be reviewed in the nextparagraph.

Proceed as follows to install the new digital I/O and 1/rev module:


2. Remove cover by unscrewing the six hex-socket set screws. This willreveal the circuit board. Locate the expansion bay on the board (seeFigure 1 early in this chapter for identification and location of parts).

3. Before unpacking the new digital I/O and 1/rev module, you mustremove any static electricity buildup from your skin. Do so by touchingany conductive material put to ground such as a water pipe.

4. Grab the new digital I/O and 1/rev module by the edges and preciselyalign both pin arrays with corresponding socket strip on the expansionslot. By design, this task module should occupy the slot labeled PO8.Gently press until module is firmly in position.


6. Connect the other end of the flat cable to the corresponding I/O portconsisting of a 12-pin strip found on the inner-back panel Use top orbottom pin strips only. Match the slot number (PO8) printed on thecircuit board to that of the inner back panel (see Figure 2.28).

Once you have completed installation of the synchronization probe according to theinstructions provided next, you may power the system and access the software inorder to enable the 1/rev pulse and to enable any or all digital inputs and outputs.


2.2.6.4: Synchronization Probe Installation and WiringPreliminary considerations

The installation of a synchronization probe essentially involves three steps:installation of the synchronization cable, installation of the probe itself, and finallyinstallation of the target.

Mounting the probe requires precision in that you must determine the exact locationof its target in relation to a fixed reference mark around the axis of the machine suchas a pole.

To install a synchronization probe, you need:

• the synchronization probe kit

• the flexible conduit kit

• a tube of glue with catalyst

• a stand

• a clean rags and a bottle of acetone

• an indelible felt

Installation of the Synchronization Cable

The synchronization cable connects the synchronization probe to the PCU unit’sdigital I/O and 1/rev module via a dedicated I/O port connector. This cable isprotected by flexible conduit. If you prefer the protection a rigid conduit, the sectionof the cable which runs to the rack holding the PCU unit must still be protected withflexible conduit. The following instructions make use of flexible conduits.

To put a synchronization cable in place, proceed as follows:

1. Mark the location of the synchronization probe and the PCU unit towhich the probe will connect.

2. Unroll the flexible conduit placed on a stand beside the rack, right up tothe location of the probe by following the course planned out for it.Then cut it.

3. With a fish-tape, run the synchronization cable through the conduit.

4. Skin the wires that lead to the probe and screw to the removableminiconnector terminals as shown on Figure 2.30.

Figure 2.30: Connecting the synchronization cable to the 3-terminal female miniconnectorthat connects to the synchronization probe


5. Fasten down the conduit permanently.

The installation of the synchronization cable is completed. The next step consists infastening down the synchronization probe. Refer to Figure 2.29 for connections tothe PCU’s rear panel I/O port.

Fastening the Synchronization Probe

You must position the probe’s proximity detector less than 4 to 5 mm (160-200 mils)from the shaft. However, sometimes it is not possible to install it that close. In suchcases, you must provide a special support to install the probe as shown by Figure2.31.

Figure 2.31: Example of a special support designed to bring the synchronization probe closerto the generator shaft

Place the support, and screw the probe according to the instructions below.

1. Pierce the support of the probe by following the instructions providedby Figure 2.32. Thread its two holes to be able to screw 5/16" - 16 ×1/2" bolts to it.

Figure 2.32: Piercing guide for the synchronization probe support

2. Fasten the support.

3. Install the probe on its support. Maintain it in place with two 5/16" - 16× 1/2" bolts and two tooth lock washers.

4. Adjust the position of the probe so that the proximity detector is lessthan 4 to 5 mm (160-200 mils) from the shaft.

5. Gently pull on the synchronization cable. Slacken the cable about 40cm (16 in.), enough to form a loop.

6. Connect the cable to the synchronization probe. Then, close the loopwith cable straps. Consult Figure 2.33.


7. Near the probe, fasten down the flexible conduit with straps, so that noone trips over the conduit and pulls on the connection between the cableand the probe.

Figure 2.33: View from above the installation of the synchronization probe.

Installation of the Target and Adjustment of the Synchronization Probe

The installation of the synchronization probe target is divided in two stages. First,you have to clean the surface of the shaft. Then you have to glue the target.

Finally, you will need to adjust the position of the synchronization probe so that it isless than 2 ± 0.5 mm (80-120 mils) from the target.

Preparation of the Surface of the Shaft

1. Search out the area where the target will be glued. Take note of theangle position according to a fixed reference mark. Do not neglect thisstep.

2. Clean it with a rag soaked with acetone.

3. Move the synchronization probe so that it touches the shaft. On theshaft, mark the edge of the proximity detector of the probe with anindelible felt to indicate the position of the synchronization target.

Gluing the Target

1. Take every necessary precaution to keep the target from falling.

2. Spread a thin layer of the glue provided in the sensor kit, on the target.If the instructions given here differ from those specified by themanufacturer of the glue, follow those given by the manufacturer.

3. Apply catalyst to the layer of glue.

4. Position the target with precision in relation to the felt mark which youmade on the shaft. Refer to Figure 2.34. Rotate the target a bit to helpspread the glue. Straighten it up and maintain it firmly in this positionfor 60 seconds.


Figure 2.34: Relative position of the target in relation to the synchronization probe

Adjustment of the Synchronization Probe

This step is very important as the adjustment of the synchronization probe determinesthe moment when the reference impulse is sent off. This impulse serves as areference for the 360 degrees revolution expected at the top of the synchronizationramp (see Figure 2.23). Therefore, the position of the probe must be very precise.

1. With a filler gage, distance the proximity detector from the probe andits target exactly 2 ± 0.5 mm (80-120 mils).

2. Firmly screw the probe in this position.


2.3: Electrical SupplyThe PCU unit is equipped with an open-air power supply located on the upper-leftcorner of the inner panel. See System Parts and Controls early in this chapter tolocate the power supply next to the main circuit board. It converts the input powerinto the DC voltage levels needed to drive the unit. The power supply accepts bothAC and DC inputs. Figure 2.35 shows the power supply.

Figure 2.35: The power supply.

2.3.1: InputThe standard input is an AC source although the power supply can handle worldwideinputs in the range of 85-250 VAC at 47-63 Hz or 110-330 VDC. The white and blackinput wires from the rear panel power port are connected to the N and L terminalsrespectively, of connector CN1 on the power supply. See Figure 2.35 to locate theterminals and Table 2.2 for the list of the input connections. Figure 2.36 illustratesthe terminal assignment of the removable rear panel input port miniconnector.Table 2.2: Input Connections of the Power Supply

Terminal Wire Color Description

Figure 2.36: Wiring of the rear panel main power Input port.

CAUTION: Do not force or pry the terminal adapter into the main power inputport. Align with plastic moldings on both PCU unit and adapter and insert gently.

2.3.2: GroundIf you are using a floating input, the power supply must be grounded. This is done byconnecting the green input wire to Terminal FG of connector CN1 on the powersupply to the ground lug of the inner panel.

The use of floating inputs is limited by the power supply's input to ground isolationvoltage. The potential difference between the floating voltage and ground must besmaller than the power supply's input to case isolation voltage.


2.4: The ICRS-485 Communication Interface

2.4.1: Overview of the ZOOM SystemThis communication interface is intended exclusively for users of VibroSystM’sZOOM monitoring system wishing to integrate selected processed vibrationmeasurements from the PCU-100 into their station database.

The ICRS-485 communication interface allows the PCU-100 unit to behave muchlike the STATE extension and provide the ZOOM system with additional statusparameter inputs. To better understand how the PCU interacts with the system, wefirst suggest that you review the basics of the ZOOM system in Section I of theAGMS and ZOOM 2000 System Hardware User’s Manual.

Figure 2.37 illustrates the ZOOM system around a generator. It outlines the layout ofthe communication network prescribed for the ZOOM system and runs the variouscombinations of acquisition units and extensions.

Figure 2.37: Layout of the ZOOM system around the generator


2.4.2: System requirementsThis is a factory-only upgrade which requires mounting a small RS-485 interfaceboard next to the memory backup cell inside the unit. Refer to Figure 2.1 to locatethe interface module. The upgrade also requires adding a 3-terminal communicationport to the rear panel mount. Please note that the communication interface takesadvantage of enhanced software features found in system software v. 1.34 and later.Therefore, a software upgrade must also be performed on earlier units.

To check the version number of the unit:• Turn on power and notice version number on the display screen during

boot-up sequence or,

• If the unit is in monitoring mode, access the configuration menu bypressing the Menu button, then use the Up (U) or Down (V) button toselect Firmware → Version. Once you have noted the versionnumber, press Menu once to return to monitoring.

Users interested in this upgrade must contact their VibroSystM representative orcontact the VibroSystM head office at one of the phone/fax numbers appearing onthe back cover of this manual for pricing, availability and shipping arrangements

To add a PCU-100 unit to a typical ZOOM installation such as the one presented inFigure 2.37, you need an acquisition unit (AGMS or ZOOM) equipped with anRS-232-C/RS-485 interface module that is not connected to any STATE or ZOOM-ALARM extension. For a full description of this module, consult your ZOOM 2000System Hardware User Manual.

You also need to have the ZOOM Configuration software installed on the controllerin order to configure the additional status parameter inputs.

2.4.3: OperationAs stated earlier, the PCU behaves much like a STATE extension and sends statusparameter data. It connects to the RS-232-C/RS-485 interface via a single twisted-pair communication cable The acquisition unit requests processed measurementsfrom the PCU, in a master-slave configuration, at intervals of 2 samples per second.

Unlike the STATE extension however, the PCU-100 cannot share the communicationline with any other extension since the ICRS-485 communication interface requires atermination resistance. Figure 2.38 shows the main components of the interface.

No software setting is required to enable communication with the ZOOM system.Once hardware setup is complete, the ZOOM acquisition unit sends a request fordata. During normal operation, the top two LEDs (see Figure 2.38) alternate duringtransmit and receive at intervals of about twice a second. The second group of LEDsare for internal error reporting only and should only glow during bootup.

The PCU-100 unit provides the ZOOM system with up to twelve (12) statusparameter inputs, or one input for each process activated using the PCU systemsoftware. In the ZOOM system, an input is a segment of the station configurationpointing to a particular sensor measurement (or in this case, to a process).

PCU-100 Programmable Unit - User Reference Manual Chapter III: The User Interface •••• 3.1

Chapter 3

The User Interface

The PCU is a software-driven programmable unit. It is designed to collect real-timesensor signals for processing into useful information and alarm event detection,management and ultimately, protection of your rotating machine investment. All thisis accomplished by the gathering and processing of the raw signals from sensorsconnected to as many as four vibration input modules. In order for the PCU unit toperform adequately in the field, it must be fitted with the appropriate hardware interms of task modules and sensors. As well, the system software must be configuredwith sensor-specific information which takes into account some design specificationsof the rotating machines. The latter is usually provided by the customer in the form ofa site survey to be forwarded to the supplier. This information will then be added tothe PCU software prior to shipment.

This chapter is provided for reference purposes only as your PCU unit comes fullyconfigured and ready for operation. Nonetheless, the next pages should prove quiteuseful in understanding unit operation as well as helping station personnel performfield upgrades to new sensors, task modules and relay cards.

Understanding of the user interface also allows users to manage the reporting ofsystem events such as alarms and OK statuses and to customize some practicalfeatures of the unit such as bar graph display IDs and conditional access codes.

Users will also be guided through the step-by-step procedures of saving aconfiguration, updating a configuration or updating the system software using thePCMCIA card slot.

Access to the various configuration and monitoring menus and sub-menus makes useof the user programmable interface by means of the VFD screen and the seven-buttonkeypad, namely:

T, U, V, S, Enter, Cancel, Menu.

This chapter will survey each menu as a step in the configuration process. Therefore,we will address each step in a chronological order. Configuration breaks down to thefollowing steps:

• General system parameters;• Vibration input modules;• Processing and analog output modules;• Digital input / output and 1/rev module;• Internal relay module;• External relay card;• Logic parameters;• Monitoring (bar graph) displays.

The next few pages will introduce some basic system characteristics and explain howthe software behaves. They will help you familiarize with the various keypad featuresas well as with the ergonomics of the user interface.

3.2 •••• Chapter III: The User Interface PCU-100 Programmable Unit - User Reference Manual

3.1: System ErgonomicsSystem ergonomics define ways to access a range of software attributes which arehardcoded into the system. Indeed, most, if not all, configuration parameters areavailable for selection right at your fingertips. All you need is to understand how toget to and enable them. The user accesses the software through the use of a seven-button keypad and views system responses to his requests and actions on the 2-lineVFD screen. Before focusing on the various steps involved in the configurationprocess, and in order to better understand how the software responds to userintervention, we provide the next few pages. They will walk you through a samplemenu structure, which can be visualized by the following tree diagram:

The option arrow points to the selected option.

When displayed, the scroll arrows indicate that other options are available forselection. The scroll up arrow indicates that the U button can be used to accessprevious options while the scroll down arrow indicates that the V button can be usedto reach the next options down the list.

3.1.2: Entering and Leaving MenusDuring normal monitoring sessions, the VFD screen displays a default window asselected by the user, such as a bargraph. To leave the default display and enter themenu, you must press the Menu button.

To leave a menu and return to the default window, press once on the Menu button.

3.1.3: Scrolling through MenusScrolling through menus makes use of the U and V scroll buttons. The V scrollbutton moves the option arrow pointer to the next menu option while the U scrollbutton returns the pointer to the previous option.

The following example shows how to scroll up and down the menu using the scrollbuttons. Here, the typical menu contains four options: 1, 2, 3 and 4. Simulateddisplays are used to show the actual layout after a specific button has been pressed.

Header

The bargraph has a resolution of 19 segments. It acts as a meter, showing the currentpercentage of the range being attained. The boundaries of the graph from 0% to100%, equal to the lower and higher limits set for that processing channel.

The user can activate twelve bar graphs based on the ten processes available. Thenumber appearing before each graph identifies the current bar graph selection. Pressthe T and S scroll buttons to toggle between bar graphs. The T scroll button displaysthe previous bar graph while the S scroll button displays the next bar graph.

The peak hold indicator is a seven-pixel high indicator that remains lit for fiveseconds to help visualize a peak value after it has been registered.

The Alert threshold indicator is a static three-pixel segment which represents thetriggering value of the Alert-type alarm along the processing range. This indicatorwill remain on-screen for as long as Alert threshold alarm monitoring is enabled.

The Danger threshold indicator is a static five-pixel high segment. It represents thetriggering value of the Danger-type alarm along the processing range. This indicatorwill remain on-screen for as long as Danger threshold alarm monitoring is enabled.


The trigger value indicator is a single pixel. It represents the value which triggeredthe alarm. The pixel disappears when the latched alarm is acknowledged or as soon asreadings fall below the Alert threshold setting for non-latching alarms.

Indicators turn reverse video (black on white) when the bar graph extends over them.

The headers complement the bar graph with miscellaneous information. Each graph isaccompanied by eleven different headers. To browse between headers, press the U orV scroll buttons. The U scroll button moves forward to the next header while the Vscroll button moves backward to the previous header.

U The first header is a personalized ID set by the user via the Configuration menu.It identifies the process associated with the bar graph. Go to page 3.68 forinstructions on how to customize this heading.

3.1.12: Saving Configuration ParametersUse the PCMCIA card slot to save your configuration parameters on a removableflash memory card. The procedure described next is strongly recommended as asafeguard against the unlikely event of a backup power outage, or any other situationwhich might lead to a deletion of some or all of your configuration parameters.

This backup feature is also very useful for cloning other PCU-100 units with oneconfiguration provided that all PCU-100 units sharing the configuration have similartask module assignments.

This procedure resembles that of saving a file onto a floppy disk inserted in thefloppy drive of a PC computer. In the PCU environment, the configurationparameters are saved in a .CFG-type file whose full name appears in the“Identification” setting described on page 3.25. To set or change the configurationidentification filename, access the configuration menu and select as follows:

Configuration →→→→ System →→→→ Identification.

Proceed as follows to save the configuration parameters:

1. Insert a PCMCIA card into a card slot and access the configuration menu for thisfeature in the following sequence:Configuration →→→→ System →→→→ Parameters →→→→ Save, then press Enter to initiate.

Update Update Update Update

> > > > SaveSaveSaveSave

2. If you are saving this configuration for the first time, that is, you are creating afile on the PCMCIA card, the following message will appear. Press Enter toreturn to the previous menu.

Parameters saved Parameters saved Parameters saved Parameters saved

Press Enter Press Enter Press Enter Press Enter

If configuration parameters have already been saved, that is, a file of the sameidentification name already exists on the PCMCIA card, the following promptwill be displayed. Press Enter to replace or Cancel to return to the previousmenu without making any changes.

Param. already saved Param. already saved Param. already saved Param. already saved

Replace it? Replace it? Replace it? Replace it?

3. If you pressed Enter to replace, the following will be displayed. Press Enteragain to return to the previous menu.

Parameters saved Parameters saved Parameters saved Parameters saved


Remember that if you wish to backup configuration parameters on the PCMCIA cardwithout overwriting those already saved, simply change the filename by accessing the“Identification” setting and then repeat the procedure described above.


3.1.13: Updating Configuration ParametersThe PCMCIA card slot allows you to update the configuration parameters. Theupdate procedure is convenient because it eliminates the task of manually configuringextra units by cloning a configuration over several PCU-100 units with similar taskmodule assignments. As well, follow this procedure to restore configurationparameters after a major firmware upgrade. See page 3.19 for more on the subject.

This procedure is essentially the same as that of retrieving a file from a floppy diskinserted in the floppy drive of a PC computer. In the case of the PCU-100environment however, you can only import configuration parameters from a filewhose filename matches the name entered in the “Identification” setting described onpage 3.25. To view the identification filename, access the proper configurationsubmenu in the following sequence:

Configuration →→→→ System →→→→ Identification.

Proceed as follows to update the configuration parameters:

1. Insert a PCMCIA card into a card slot and access the configuration menu for thisfeature in the following sequence:Configuration →→→→ System →→→→ Parameters →→→→ Updateand press Enter to begin the update process.

Date last change Date last change Date last change Date last change

> Update Update Update Update

2. If the PCU-100 unit scans the PCMCIA card and fails to find a file whose namematches the name provided in the “Identification” setting for the currentconfiguration, the following prompt is displayed. Press Enter to return to theprevious menu.

File not found File not found File not found File not found


Furthermore, before initiating update, the system software looks for the versionnumber of the file from which to update. The update can take place if the filecarries the same version number or if only the last digit of the system softwareversion number has changed.

For example, a PCU-100 unit running version 1.40 of the system software willnot accept updates from a file created with version 1.52. However, the unit willaccept updates from files created with versions 1.41 or 1.42.

Incompatible version will prompt the following message. Press Enter to returnto the previous menu without making any changes to the current configuration.

Incompatible Version Incompatible Version Incompatible Version Incompatible Version


3. Compatible version numbers will prompt the following message. The top lineindicates the date and time of the last change made to the current configurationwhile the bottom line displays the date and time at which the configuration filewas saved onto the PCMCIA card. Press Enter to go forward or Cancel to goback to the previous menu, leaving the current configuration unchanged.

SYS:1999/01/15 13:55 SYS:1999/01/15 13:55 SYS:1999/01/15 13:55 SYS:1999/01/15 13:55

4. Pressing Enter brings up the next prompt in the update procedure. The top lineidentifies the task module assignment of the current PCU-100 unit. The bottomline identifies the task module assignment for the configuration saved on thePCMCIA card.

SYS:V1A1----N1--R2 SYS:V1A1----N1--R2 SYS:V1A1----N1--R2 SYS:V1A1----N1--R2

UPD:V1A1----N1--R2 UPD:V1A1----N1--R2 UPD:V1A1----N1--R2 UPD:V1A1----N1--R2

If your current task module assignment matches that of the new configurationfile, press Enter to go forward. Otherwise, press Cancel to go back to theprevious menu, leaving the configuration unchanged.

You may update a configuration even if the task moduleassignment of the PCU-100 unit does not match that of theconfiguration file on the PCMCIA card. However, default values will berestored for any task module not accounted for in the configuration file.

5. The next prompt is the last warning before the update takes place. As indicated,press Enter to update or Cancel to return to the previous menu and leave theconfiguration unchanged.

Update and Reboot? Update and Reboot? Update and Reboot? Update and Reboot?


If, for some reason, you are unwilling to update at this time, pressing Cancelwill prompt the following message:

Param. not Updated Param. not Updated Param. not Updated Param. not Updated


You may now press Enter to return to the Configuration menu with no changeto the current configuration.

6. Pressing Enter initiates the update as indicated by the following prompt. Assoon as configuration transfer is complete, the PCU-100 unit automaticallyrestarts with the updated configuration parameters.

3.1.14: Updating System Software (firmware)From time to time, VibroSystM will inform users on the availability of systemsoftware updates for the PCU-100 unit equipped with a PCMCIA slot. Before goingany further, it is important that users distinguish between minor and major updates.

• a minor update is a file whose version number matches your currentsoftware version except for the last digit. Such would be the case whenupdating from version 1.40 to 1.41. Minor updates are often referred toas "maintenance updates" because they provide bug fixes to minorproblems encountered by users during daily operation of their units;


• a major update is a file whose version differs from your currentsoftware version by more than one digit (ex.: updating version 1.40 to1.50). In most cases, major updates bring new features to the PCU-100environment. When performing a major software update, keep a copy ofyour configuration parameters on a PCMCIA card as this configurationmust be reloaded following the update. Review paragraphs 3.1.12 and3.1.13 before performing major system software upgrades.

This procedure is essentially the same as that of adding software to a PC computerfrom a floppy disk. Proceed as follows to update the system software:

1. Insert the PCMCIA card into a card slot and access the configuration menu forthis feature in the following sequence:Firmware →→→→ Updateand press Enter to begin the update process.

If no update file is detected on the card, you will be prompted as follows. Simplypress Enter to return to the configuration menu.

> File not found File not found File not found File not found


If update files are found, the display will read as follows:

PCU100R1.41PCU100R1.41PCU100R1.41PCU100R1.41

1999/03/30 1999/03/30 1999/03/30 1999/03/30

12:2312:2312:2312:23

System software update files are identified by their name, as well as by the dateand time of creation. If several software files are present on the card, use the up(U ) and down (V) arrow buttons to toggle between filename in order todetermine which file is right for your application.

You may now access the system software and review the configuration by followingthe description tables. As indicated earlier, the configuration process breaks down tothe following steps:

• General system parameters;• Vibration input modules;• Processing and analog output modules;• Digital input/output and 1/rev module;• Internal relay module;• External relay card;• Logic parameters;• Monitoring (bar graph) displays.

You may also consult Appendix C: The VibraWatch Software Menu Structure for acomprehensive listing of software elements.


3.2.1: General System ParametersThe general system parameters require setting the user language, the conditionalaccess code, time, and date. Furthermore, depending on the number and type of taskmodules installed and the extent of the monitoring, you may enable up to 8 front-panel LEDs for alarm event and OK status notification.

ALARM LEDs are used to report alarms triggered by excessive process values. Asexplained earlier in Chapter 2, processes involve calculations performed on selectedvibration input signals. OK LEDs are intended to notify the user of any faultoccurring on any or all of the vibration input channels during normal monitoring asfaulty input channels are sufficient cause to invalidate reported alarms. Note thatALARM and OK LEDs are usually matched.

As will be explained later in paragraph 3.2.6: Logic Parameters on page 3.62, any orall LEDs can be assigned to voting logic which greatly extends the scope of eventsthat can be reported by the PCU unit.

The table below takes a step-by-step look at configuration of the general parameters.The "Action" column lists the actual number of keystrokes required to access anyrequested menu. The “Comments” column describes and sets the requirements for theaction about to be taken. As well, it gives references to other topics throughout theconfiguration process considered relevant for the task The “Menu Contents” columnexpands beyond the two-line VFD screen by listing the entire menu being accessed.

3.2.2: Vibration Input ModulesFollowing configuration of the general parameters, you must customize yourmonitoring environment according to the number of vibration input modules and thetype of sensors found at the other end of the measuring chain. The vibration inputmodules are dual-channel input boards which acquire the raw sensor signals fromproximity probes (such as the PCS sensor), accelerometers and velocimeters. Theconditioned signals are then sent to the processing and analog output modules. Thisconfiguration involves enabling each sensor input channel and registering the type ofsensor connected to each input port. When reviewing this procedure, remember thatthe PCU-100 accepts up to eight sensors and four vibration input modules.

The next table takes a step-by-step look at configuration of the vibration inputmodule. The "Action" column lists the actual number of keystrokes required to accessany requested menu. The “Comments” column describes and sets the requirements forthe action about to be taken. As well, it identifies other topics in the configurationprocess considered relevant for the task The “Menu Contents” column expandsbeyond the two-line VFD screen by listing the entire menu being accessed.

3.2.3: Processing and Analog Output ModuleConfiguration of the processing and analog output module usually follows that of thevibration input module since its purpose is to further process sensor signals. Thismodule provides four input channels and four output signals. Each output, orprocessed signal can be viewed in real-time on the VFD screen or displayed on userequipment, such as an oscilloscope, connected to the rear panel output ports for thatmodule. Refer to Chapter 2 to understand the role of the processing and analog outputmodule in the system.

The following table takes a step-by-step look at configuration of the processing andanalog output module. The "Action" column lists the actual number of keystrokesrequired to access any requested menu. The “Comments” column describes and setsthe requirements for the action about to be taken. As well, it gives references to othertopics in the configuration process considered relevant for the task The “MenuContents” column expands beyond the two-line VFD screen by listing the entiremenu being accessed.

Some users may notice that the values used in this exercise do not match theirconfiguration. Remember that these pages rely on default settings which are suitablefor use with PCS-type sensors. VibroSystM supplies a configuration report whichaddresses the particulars of the customer’s requirements with each shipment.

3.2.6: Logic ParametersThis procedure is required to enable the addressable system features known as logicparameters. On one hand, some features, referred to as input logic parameters, can beprogrammed to react to a logic status change (0 or 1) initiated by compatible remoteinstrumentation. Such instrumentation delivers an 1/0 logic control pulse interpretedby the digital input/output and 1/rev module's digital inputs associated with logicparameters. See also page 3.55 for details on configuring the digital input and outputchannels.

On the other hand, a set of system features, referred to as output logic parameters, aredesigned to communicate system events. Output logic parameters can be assigned tothe "OK" LEDs found on the front panel, or to digital output channels of the digitalI/O and 1/rev module for notification by way of a remote instrumentation panel.

Output logic parameters includes the application of voting logic. This featuresignificantly extends the number and scope of events reported by the PCU. This isaccomplished by building logic functions by combining two or three elements in theform of input channels, alarm channels or other system events, with each elementseparated by a logic argument: “AND” or “OR” The result of each logic functioncalls for a logic change - a new system event. In turn, this event can be reported on anALARM or OK LED or directed to a digital output for activation of externalannunciators or safety devices.

The “AND” logic requires that all elements be active for the function to activate. Onthe other hand, the “OR” logic requires that only one event be active for the logicoutput to initiate a logic change.

In general you should build “AND” functions when the two elements representexactly the same measurement variable (such as sensor redundancy) and when it islikely that a sensor failure will trigger false alarms. The “OR” voting logic function isappropriate when the two elements do not represent exactly the same measurementvariable. When configured adequately, this feature ensures that no significant systemevent goes by unreported.

Here is an example of a logic function using the “AND” type argument.

element 1event tag

argument element 2event tag


function tag

VI1CH1OK AND VI1CH2OK AND LOGIC_1 AND_1

Notice the use of tags to represent each element. Both VI1CH1OK and VI1CH2OK,represent the status OK/not OK tags for vibration input channels. They must triggeran alarm (status not OK) for this logic function to become active. LOGIC_0 andLOGIC_1 are floating tags which are added to a function in order to complete theequation and make up for the unassigned channel or event tags.

Use LOGIC_1 in a “AND”-type function to emulate an active system event;Use LOGIC_0 in a “OR”-type function to emulate an inactive system event.

Here is an example of a logic function using the “OR” type argument.

element 1event tag



function tag

AO1CH1A1 OR AO1CH2A1 OR LOGIC_0 OR_1

The first two elements represent unrelated system events. As soon as one eventtriggers an alarm, the logic function becomes active.


The system provides eight “AND” voting logic functions and eight “OR” voting logicfunctions. Build as many functions as are required by your monitoring application.

You may already have performed configuration of the digital I/O and 1/rev taskmodule. As part of this procedure, you have selected a tag for each input and outputchannel included on the I/O module. For the most part, these tag choices wererepresentative of the logic parameters. You must now enable those logic parametersone by one.

The following table takes a step-by-step look at configuration of the logic parameters.The "Action" column lists the actual number of keystrokes required to access anyrequested menu.

APPENDIX A: Unit ConfigurationYour PCU-100 unit is shipped preprogrammed and ready to operate with a flick ofthe power switch. It takes into account the information provided by the customer byway of a site survey. Nonetheless, we are providing the following configurationcharts for reference purposes. They run down all the variables that make up the PCU-100 software and provide an insight as to the implication of customizing the softwareto the user's monitoring requirements.

Refer to the following configuration charts to review the default values which areautomatically set after system upgrade. It is good practice to duplicate the followingpages in order to write down the new variables before entering them into the system.Annotated copies of this Addendum may also accompany the unit to account for suchvariables as threshold settings.

For security reasons, we strongly recommend that to save your working configurationon a PCMCIA card for quick recovery in the unlikely event of a backup poweroutage or major system upgrade.

APPENDIX B: Process Overview

This section uses graphic symbols to represent the processes which occur atdifferent stages inside the PCU unit. First, it identifies the digital processesperformed on the raw input signal, that is, at the point of entry by the vibration inputmodule. Second, it illustrates each of the eight processes performed on the vibrationinput signal by the processing and output module. Each process is available forselection by way of the PCU-100 software interface described in Chapter 3.

The diagram below breaks down the digital processing performed on the raw sensorsignal. Notice that AC coupling is a selectable feature which enables or bypasses theHigh Pass Filter depending on your application.
