Introduction

This chapter provides an overview of the XM-720 Machine Monitor. It also discusses the components of the monitor.

The XM-720 Machine Monitor is referred to as XM-720 or monitor throughout this manual.

Introducing the XM-720 Machine Monitor

The XM-720 monitor is a 2-channel machine monitor designed for monitoring the condition of fans, pumps, motors, turbines, gear drives, and other machines. The XM-720 is designed to be used with accelerometers, velocity and non-contact sensors. It samples inputs, compares them to threshold values, performs self-test routines, and provides outputs to bargraph displays, relays, and LED indicator lights.

There are three variations of the XM-720 Machine Monitor:

6 Introduction

Figure 1.1 XM-720 Front and Side View

Each monitor offers:

• two vibration transducer connections (eddy current probes, accelerometers, velocity sensors, AC voltage output or DC voltage output measurement devices)

• one tachometer input signal connection• remote relay reset connection• three relays available for module or transducer fault, warning and trip• isolated 4-20mA per channel into a maximum load of 250 ohm• three buffered output signals on the front panel BNC connectors• two front panel digital meters • four front panel LED indicators (module, transducer, warning, and trip

status)

System Description The concept of machine monitoring is quite simple. During normal operation, the machine’s "vital signs" remain within relatively narrow ranges. If a mechanical problem develops, it will be reflected as a change in one or more of these vital signs. This change will be detected by the XM-720 and cause an alarm.

The monitoring system consists of a number of transducers connected to the XM-720. The transducers installed on the machine convert the "vital signs" to electrical signals that are transmitted to the XM-720 monitor.

The XM-720 accepts the signals from the transducers, processes and measures the signals, and closes electrical relay contacts if one of the signals increases too much. The relays can be connected to annunciators or to automatic machine controls.

Hazardous Locations

Due to the proximity of some control rooms to process machinery, the control room interior may be designated as a hazardous area within the definition of Article 500 of the (U.S.) National Electrical Code, or similar codes in other countries.

If the control room is classified as a Division 2 area (N.E.C.), present interpretation of the code usually permits the operation of electrical equipment if two conditions are met during normal operation:

1. Arcing or sparking contacts must not be exposed, and

2. No surface temperature may exceed 80% of the ignition temperature (in °C) of the hazardous gas or vapor.

The XM-720 monitor meets the first requirement since all relay contacts are hermetically sealed. The second requirement is met if ignition temperature of the hazardous gas or vapor is above 200°C (392°F).

Wiring

Use solid or stranded wire. All wiring should meet the following specifications:

• 12 to 28 AWG (0.08 to 2.5 mm2)

• Recommended strip length 8 to 9 millimeters (0.33 inches)

Mounting the XM-720 Monitor

The XM-720 monitor is designed for installation in a wall, panel cutout, or custom enclosure.

Connecting the Power Supply

The XM-720 monitor accepts inputs from 100-240V ac (47 to 63 Hz). The internal power supply has internal (not accessible) input fuse. No other protection is required. In order to meet local requirements, please consult local codes and regulations for proper installation. Maximum rating of an overcurrent protective device shall not exceed 15A.

Wire the AC power connections to the back panel as shown in Figure 2.4.

Figure 2.4 Power Supply Connection

Connecting the Relays

The XM-720 monitor has both Normally Open (NO) and Normally Closed (NC) relay contacts. Normally Open relay contacts close when the control output is energized. Normally Closed relay contacts open when the control output is energized.

The alarms associated with the relay and whether the relay is normally de-energized (non-failsafe) or normally energized (failsafe) depends on the configuration of the monitor.



The XM-720 back panel terminal block is equipped with three single-pole, double-throw relays. Figures 2.5 to 2.7 show the connection for the three relays.

Module/Transducer Fault Relay

In the provided configuration files, the Fault relay is configured to be a failsafe relay and is set up to activate if any one of the conditions occurs:

• There is a hardware or firmware failure.• A transducer fault is detected on the associated transducer.

You can change the alarms associated with this relay as well as the behavior of the relay using the XM Serial Configuration Utility. Refer to Editing the XM-720 Parameters on page 44 for more information.

Figure 2.5 shows the on-board relay connection for the Fault relay.

Figure 2.5 Wiring Connection for Fault Relay (Failsafe)

Warning Relay

In the provided configuration files, the Warning relay is configured to activate when the overall measurement in either channel exceeds the alert threshold levels (same conditions that activate the Warning LED). This relay is configured as a non-failsafe relay. Figure 2.6 shows the on-board relay connection for the Warning relay.

The alert threshold levels and the behavior of the relay can be changed using the XM Serial Configuration Utility. Refer to Editing the XM-720 Parameters on page 44.

Trip Relay

In the provided configuration files, the Trip relay is configured to activate when the overall measurement in either channel exceeds the danger threshold level (same conditions that activate the Trip LED). This relay is also configured as a non-failsafe relay. Figure 2.7 shows the on-board relay connection for the Trip relay.

The danger threshold level and the behavior of the relay can be changed using the XM Serial Configuration Utility. Refer to Editing the XM-720 Parameters on page 44.

Figure 2.7 Wiring Connection for Trip Relay (Non-failsafe)



Connecting the Remote Relay Reset Signal

In the provided configuration files, the XM-720 relays are configured to be latching relays. This means the relays stay activated even when the condition that caused the alarm has ended. The remote relay reset signal enables you to reset the XM-720 relays remotely after you have corrected the alarm condition.

Wire the Remote Relay Reset Signal to the XM-720 back panel as shown in Figure 2.8.

Figure 2.8 Remote Relay Reset Signal Connection

Connecting the Transducers

The XM-720 monitor can accept input from any Entek non-contact eddy current probe, a standard IEPE acclerometer, velocity transducer, AC voltage output or a DC voltage output measurement device.

ATTENTION The switch input power supply must be grounded at a single point. Connect the Switch Return signal to chassis or earth ground at either the XM-720 system, the switch, or other equipment that is wired to this switch. If grounding at the XM-720 system, connect a jumper between the Switch RTN terminal and any available Chassis GND terminal.



The sensitivity, operating range, and power requirements have been predefined in the provided configuration files. The characteristics of the transducer and the signal processing performed on the input signals can be changed using the XM Serial Configuration Utility. Refer to Transducer Parameters on page 44.

Setting the Buffer Range for the Transducer

The XM-720 provides buffered outputs of all transducer input signals through the BNC connectors on the front panel.

The voltage operating range of the buffered outputs must be configured to coincide with the corresponding transducer bias range. This operating range is configured by placing a jumper from terminal 5 (channel 1) and terminal 22 (channel 2) to terminal 6 (Positive Buffer Bias) or terminal 21 (Buffer -) on the XM-120/121/122 module, depending on the transducer. The buffered output operating range is configured independently per channel.

Table 2.3 Configuring Buffered Output Operating Range

IMPORTANT The 1440-PK02-05M2 (gSE) monitor can measure both "standard" vibration, similarly to the 1440-PK02-05M0, and g’s Spike Energy™ (gSE). It can produce the gSE measurement only with an IEPE accelerometer or externally powered sensor.

IMPORTANT By default, both buffered outputs have been wired for a positive bias transducer (accelerometer and powered sensor). This means that orange jumper wires have been supplied on the XM-120/121/122 terminal block between terminals 5, 6, and 22 (see Figure 2.9).

Figure 2.9 Jumpers for buffer input wiring

If the transducer is not a positive bias transducer, follow these guidelines:

• For a non-contact sensor, remove the orange jumper between terminals 5 and 6 (terminals 22 and 6 for channel 2) and install it between terminals 5 and 21 (terminals 22 and 21 for channel 2).

• For a non-bias sensor, such as a velocity sensor, remove the orange jumper between terminals 5 and 6 (terminals 22 and 6 for channel 2).

Refer to Table 2.3 for details. Refer to the XM Users Guide for more information about the XM-120/121/122 module.

Bargraph Meters

The XM-720 front panel has two vertical-scale meters, one for each input channel. Each meter consists of 31 solid-state lamps (light emitting diodes) arranged one above the other. Scale markings on the window appear at 3% increments, thus there is one scale mark for each of the thirty lamps.

In the provided configuration files, each meter is configured to continuously display the overall vibration level. The amplitude of the signal appears as a continuous bright light next to the one of the thirty scale marks. This simplified display makes it easy for you to recognize potential problems as the measured signal amplitude approaches one of the setpoints.

The measurement displayed in the meter, the full scale, and the alarm and trip (danger) thresholds are configurable using the XM Serial Configuration Utility. Refer to Chapter 3 for more information about the XM Serial Configuration Utility.

The XM-720 is shipped with clear self-adhesive caption sheet for customizing the meter scale. The caption stickers contain the most popular measured units and ranges. The caption sheet also contains orange and red arrows for labeling the alert and danger (trip) threshold levels.

Follow these instructions to customize the scaled face plate.

1. Remove the front bezel. To do this, insert a blade-type screwdriver between the plastic bezel frame and front panel and lift the bezel off.

2. Remove the scaled faceplate. Be careful not to scratch the clear lens.

3. Peel the desired measured units and the orange and red arrows from the caption sheet and place on the scaled faceplate. Refer to To determine placement for Alert and Danger Threshold Arrows on page 33 for an example.

4. Replace the faceplate, lens and bezel.

Glossary

alarm

An alarm alerts you to a change in a measurement. For example, an alarm can notify you when the measured vibration level for a machine exceeds a pre-defined value.

band

A frequency range, such as the frequency range between 1,800 and 3,200Hz.

bus off

A bus off condition occurs when an abnormal rate of errors is detected on the Control Area Network (CAN) bus in a device. The bus-off device cannot receive or transmit messages on the network. This condition is often caused by corruption of the network data signals due to noise or baud rate mismatch.

current configuration

The current configuration is the most recently loaded set of configuration parameters in the XM module’s memory. When power is cycled, the current configuration is loaded with either the saved configuration (in EEPROM) or the factory defaults (if there is no saved configuration). In addition, the current configuration contains any configuration changes that have been downloaded to the module since power was applied.

disarm state

See Program mode.

EEPROM

See NVS (Non-Volatile Storage).

Electronic Data Sheet (EDS) Files

EDS files are simple text files that are used by network configuration tools such as RSNetWorx for DeviceNet to describe products so that you can easily commission them on a network. EDS files describe a product device type, revision, and configurable parameters.

failsafe

Failsafe means that when in alarm, the relay contacts are in their "normal," de-energized, or "shelf-state" positions. In other words, normally closed relays are closed in alarm, and normally open relays are open in alarm. With failsafe operation, a power failure equals an alarm.


Glossary 60

For failsafe operation, the following are true:

• Under nonalarm (with power applied to the unit) conditions, the relay closes the circuit between the common and the N.O. terminals

• Under alarm or loss-of-power conditions, the relay changes state to close the circuit between the common and the N.C. terminals.

gSE measurement

A special type of signal processing. gSE, or Spike Energy, is useful for detecting low amplitude, high frequency signals characteristic of bearing and gearbox defects.

gSE spectrum

A special type of spectrum measurement using gSE signal processing. gSE, or Spike Energy, is useful for detecting low amplitude, high frequency signals characteristic of bearing and gearbox defects.

Help window

A window that contains help topics that describe the operation of a program. These topics may include:

• An explanation of a command.• A description of the controls in a dialog box or property page.• Instructions for a task.• Definition of a term.

high pass filter

A filter that excludes all frequencies below a defined frequency. It allows, or passes, frequencies above the defined frequency. It is useful for removing low frequency signal components that would dominate the signal.

low pass filter

A low pass filter excludes frequencies above a defined frequency. It allows, or passes, frequencies below the defined frequency. It is useful as an anti-aliasing filter.

non-failsafe

Non-failsafe means that when in non-alarm, the relay contacts are in their "normal," de-energized, or "shelf-state" positions. In other words, the relay is normally not energized and energizes (pulls in) upon alarm condition.


Glossary 61

For non-failsafe operation, the following are true:

• Under nonalarm conditions, the relay closes the circuit between the common and the N.C. (normally closed) terminals.

• Under alarm conditions, the relay changes state to close the circuit between the common and the N.O. (normally open) terminals.

NVS (Non-Volatile Storage)

NVS is the permanent memory of an XM module. Modules store parameters and other information in NVS so that they are not lost when the module loses power (unless Auto Save is disabled). NVS is sometimes called “EEPROM.”

online help

Online help allows you to get help for your program on the computer screen by pressing F1. The help that appears in the Help window is context sensitive, which means that the help is related to what you are currently doing in the program.

orders

Multiples of the operating speed of a piece of equipment. The first order is the operating speed. The second order is two times the operating speed, and so on.

Program mode

The XM module is idle. Typically this occurs when the module configuration settings are being updated with the XM Configuration program. In Program mode, the signal processing/measurement process is stopped. The status of the alarms is set to the disarm state to prevent a false alert or danger status.

Run mode

In Run mode, the module collects measurement data and monitors each measurement device.

settling time

The amount of time it takes a measurement to reach 90% of the final value given a step change in the input signal.

signal detection

Defines the method of conditioning or measuring a dynamic input signal. Peak (0 to the peak voltage), Peak-Peak (minimum peak to maximum peak), and RMS (square root of the mean of the square of the values) are the most common methods of signal detection.


Glossary 62

startup/coast-down trend

A speed-base trend that is collected in an XM module during the startup or coast-down of a machine when the measured machine speed crosses into a defined speed range.

transducer

A transducer is a device for making measurements. These include accelerometers, velocity pickups, displacement probes, and temperature sensors.

virtual relay

A virtual relay is a non-physical relay. It has the same capabilities (monitor alarms, activation delay, change status) as a physical relay only without any physical or electrical output. The virtual relay provides additional relay status inputs to a controller or PLC.

XM configuration

XM configuration is a collection of user-defined parameters for XM modules.

XM Serial Configuration Utility software

XM Serial Configuration Utility software is a tool for monitoring and configur-ing XM modules. It can be run on computers running Windows 2000 service pack 2, Windows NT 4.0 service pack 6, or Windows XP operating systems.
