Introducing the XM-122 gSE Vibration Module

The XM-122 gSE Vibration module is an intelligent 2-channel special-purpose

vibration monitor. It is part of the Allen-Bradley™ XM DIN rail mounted condition monitoring and protection modules that operate both in stand-alone applications or integrate with Programmable Logic Controllers (PLCs) and control system networks.

The XM-122 module includes special circuitry and firmware that enables it to measure both conventional vibration (similar to the XM-120) and g’s Spike Energy™ (gSE). This makes the module ideal for monitoring machines with rolling element bearings.

gSE is an Entek developed signal processing technique that provides an accurate measure of the energy generated by transient or mechanical impacts. The gSE measurement provides early detection of surface flaws in rolling-element bearings, metal-to-metal contacts, insufficient bearing lubrication, and process-related problems, such as dry running, cavitation, flow change, and internal re-circulation.

The XM-122 alternates collection of conventional vibration measurements and gSE overall and gSE spectra measurements. The time the module spends updating each set of measurements during a monitoring-time is dependant on the configuration. The module continuously monitors transducer bias and speed as well.

Series, a family of

The XM-122 can power and accept input from standard eddy current probe systems and Integrated Electronics Piezo Electric (IEPE) accelerometers. It can also accept signals from most standard voltage output measurement devices such as a velocity or pressure transducer. In addition to vibration inputs, the XM-122 accepts one tachometer input to provide speed measurement and order analysis functions.

The XM-122 also includes a single on-board relay, expandable to five, an integral tachometer, two 4-20 mA outputs, and a buffer output for each input. The module can collect data under steady-state and startup/coast-down conditions, capture trend and spectra or waveform data on event, and monitor up to 16 alarms making the module a complete monitoring system.

The module can operate stand-alone, or it can be deployed on a standard or dedicated DeviceNet network where it can provide real-time data and status information to other XM modules, PLCs, DCS and Condition Monitoring Systems.

The XM-122 can be configured remotely via the DeviceNet network, or locally using a serial connection to a PC or laptop. Refer to Chapter 3 for a list of the configuration parameters.

XM-122 Module Components

The XM-122 consists of a terminal base unit and an instrument module. The XM-122 gSE Vibration Module and the XM-940 Terminal Base are shown below.

Introduction 3

IMPORTANT

• XM-122 gSE Vibration Module - The module mounts on the XM-940

terminal base via a keyswitch and a 96-pin connector. The module contains the measurement electronics, processors, relay, and serial interface port for local configuration.

The XM-441 Expansion Relay module may be connected to the XM-122 module via the XM-940 terminal base.

When connected to the module, the Expansion Relay module simply “expands” the capability of the XM-122 by adding four additional epoxy-sealed relays. The XM-122 controls the Expansion Relay module by extending to it the same logic and functional controls as the on-board relay.

IMPORTANT

See Application Technique "XM Power Supply Solutions", publication ICM-AP005A-EN-E, for guidance in architecting power supplies for XM systems.

Grounding Requirements

Use these grounding requirements to ensure safe electrical operating circumstances, and to help avoid potential emi and ground noise that can cause unfavorable operating conditions for your XM system.

DIN Rail Grounding

The XM modules make a chassis ground connection through the DIN rail. The DIN rail must be connected to a ground bus or grounding electrode conductor using 8 AWG or 1 inch copper braid. See Figure 2.2.

Use zinc-plated, yellow-chromated steel DIN rail (Allen-Bradley part no. 199-DR1 or 199-DR4) or equivalent to assure proper grounding. Using other DIN rail materials (e.g. aluminum, plastic, etc.), which can corrode, oxidize, or are poor conductors can result in improper or intermittent platform grounding.

IMPORTANT

24 V Common Grounding

24 V power to the XM modules must be grounded. When two or more power supplies power the XM system, ground the 24 V Commons at a single point, such as the ground bus bar.

If it is not possible or practical to ground the -24Vdc supply, then it is possible for the system to be installed and operate ungrounded. However, if installed ungrounded then the system must not be connected to a ground through any other circuit unless that circuit is isolated externally. Connecting a floating system to a non-isolated ground could result in damage to the XM module(s) and/or any connected device. Also, operating the system without a ground may result in the system not performing to the published specifications regards measurement accuracy and communications speed, distance or reliability.

The 24 V Common and Signal Common terminals are internally connected. They are isolated from the Chassis terminals unless they are connected to ground as described in this section. See Terminal Block Assignments on page 18 for more information.

Transducer Grounding

Make certain the transducers are electrically isolated from earth ground. Cable shields must be grounded at one end of the cable, and the other end left floating or not connected. It is recommended that where possible, the cable shield be grounded at the XM terminal base (Chassis terminal) and not at the transducer.

DeviceNet Grounding

The DeviceNet network is functionally isolated and must be referenced to earth ground at a single point. XM modules do not require an external DeviceNet power supply. Connect DeviceNet V- to earth ground at one of the XM modules, as shown in Figure 2.6.

ATTENTION

Figure 2.6 Grounded DeviceNet V- at XM Module

Use of a separate DeviceNet power supply is not permitted. See Application Technique "XM Power Supply Solutions", publication ICM-AP005A-EN-E, for guidance in using XM with other DeviceNet products.

Mounting the Terminal Base Unit

For more information on the DeviceNet installation, refer to the ODVA Planning and Installation Manual - DeviceNet Cable System, which is available on the ODVA web site (http://www.odva.org).

Switch Input Grounding

The Switch Input circuits are functionally isolated from other circuits. It is recommended that the Switch RTN signal be grounded at a single point. Connect the Switch RTN signal to the XM terminal base (Chassis terminal) or directly to the DIN rail, or ground the signal at the switch or other equipment that is wired to the switch.

The XM family includes several different terminal base units to serve all of the XM modules. The XM-940 terminal base, Cat. No. 1440-TB-A, is the only terminal base unit used with the XM-122 module.

22 Installing the XM-122 gSE Vibration Module

IMPORTANT

TIP

IMPORTANT

Connecting the Relays

The XM-122 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 module. Refer to Relay Parameters on page 78 for details.

Table shows the on-board relay connections for the module.

All XM relays are double pole. This means that each relay has two contacts in which each contact operates independently but identically. The following information and illustrations show wiring solutions for both contacts; although, in many applications it may be necessary to wire only one contact.

The Expansion Relay module may be connected to the module to provide additional relays. Refer the XM-441 Expansion Relay Module User Guide for wiring details.

The NC/NO terminal descriptions on page 20 correspond to a de-energized (unpowered) relay.

When the relay is configured for non-failsafe operation, the relay is normally de-energized.

When the relay is configured for failsafe operation, the relay is normally energized, and the behavior of the NC and NO terminals is inverted.

Connecting the Tachometer Signal

The XM-122 provides a single tachometer input signal. The signal processing performed on the tachometer signal depends on the configuration of the module. See page 71 for a description of the tachometer parameters.

If you are not using the tachometer input, set the Pulses per Revolution parameter to zero (0). This will disable the tachometer measurement and prevent the module from indicating a tachometer fault (TACH indicator flashing yellow). A tachometer fault occurs when no signal pulses are received on the tachometer input signal for a relatively long period.

TIP

ATTENTION

Connecting the Remote Relay Reset Signal

If you set the module relay to latching and the relay activates, the relay stays activated even when the condition that caused the alarm has ended. The remote relay reset signal enables you to reset your module relay remotely after you have corrected the alarm condition. This includes latched relays in the Expansion Relay module when it is attached to the XM-122.

If you set a module relay to latching, make sure that any linked relays, such as relays in an XM-440 Master Relay Module, are not configured as latching. When both relays are set to latching, the relay in each module will have to be independently reset when necessary.

You can discretely reset a relay using the serial or remote configuration tool.

Wire the Remote Relay Reset Signal to the terminal base unit as shown in Figure 2.30.

Figure 2.30 Remote Relay Reset Signal Connection

The Switch Input circuits are functionally isolated from other circuits. It is recommended that the Switch RTN signal be grounded at a signal point. Connect the Switch RTN signal to the XM terminal base (Chassis terminal) or directly to the DIN rail, or ground the signal at the switch or other equipment that is wired to the switch.

Figure 2.34 Mini Connector

A special cable (Cat. No. 1440-SCDB9FXM2) is required for this connection. The connector that inserts into the PC is a DB-9 female connector, and the connector that inserts into the module is a USB Mini-B male connector.

If you connect or disconnect the serial cable with power applied to the module or the serial device on the other end of the cable, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

If 24 V Common is not referenced to earth ground, we recommend you use an RS-232 isolator, such as Phoenix PSM-ME-RS232/RS232-P (Cat. No. 1440-ISO-232-24), to protect both the XM module and the computer.

DeviceNet Connection

The XM-122 includes a DeviceNet™ connection that allows the module to communicate with a Programmable Logic Controller (PLC), Distributed Control System (DCS), or another XM module.

DeviceNet is an open, global, industry-standard communications network designed to provide an interface through a single cable from a programmable controller to a smart device such as the XM-122. As multiple XM modules are interconnected, DeviceNet also serves as the communication bus and protocol that efficiently transfers data between the XM modules.

The DeviceNet power circuit through the XM module interconnect, which is rated at only 300 mA, is not intended or designed to power DeviceNet loads. Doing so could damage the module or terminal base.

To preclude this possibility, even unintentionally, it is recommended that DeviceNet V+ be left unconnected.

You must ground the DeviceNet shield at only one location. Connecting the DeviceNet shield to terminal 10 will ground the DeviceNet shield at the XM module. If you intend to terminate the shield elsewhere, do not connect the shield to terminal 10.

The DeviceNet network must also be referenced to earth at only one location. Connect DNet V- to earth or chassis at one of the XM modules.

The DNet V+ and DNet V- terminals are inputs to the XM module. Do not attempt to pass DeviceNet power through the XM terminal base to other non-XM equipment by connecting to these terminals. Failure to comply may result in damage to the XM terminal base and/or other equipment.

Terminate the DeviceNet network and adhere to the requirements and instructions in the ODVA Planning and Installation Manual - DeviceNet Cable System, which is available on the ODVA web site (http://www.odva.org).

Mounting the Module

The XM-122 mounts on the XM-940 terminal base unit, Cat. No. 1440-TB-A. We recommend that you mount the module after you have connected the wiring on the terminal base unit.

The XM-122 module is compatible only with the XM-940 terminal base unit. The keyswitch on the terminal base unit should be at position 1 for the module.

Do not attempt to install XM-122 modules on other terminal base units.

Do not change the position of the keyswitch after wiring the terminal base.

This module is designed so you can remove and insert it under power. However, when you remove or insert the

module with power applied, I/O attached to the module can change states due to its input/output signal changing conditions. Take special care when using this feature.

When you insert or remove the module while power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

TIP

XM-122 Measurement Modes

The XM-122 alternates between two measurement modes while it is actively measuring the channel inputs: conventional mode and gSE mode.

The XM-122 operates in conventional vibration mode for a period of time based on the configuration (table 3.A). During conventional mode, the module measures the overall, spectrum, waveform, conventional bands, vectors, Not 1X, and sum harmonics values.

The module then reconfigures itself and transitions to gSE mode for a time period based on the configuration (table 3.B). In gSE mode, the module calculates gSE overall, gSE spectrum and gSE bands. The module then returns to conventional mode, and the cycle repeats.

The most recent measured values are available via the 4-20mA outputs, the XM Serial Configuration Utility, or the network configuration software. During conventional and gSE mode, the module measures speed and transducer bias.

If there is a tachometer fault and the conventional spectrum is configured to be "synchronous," the conventional measurement will timeout and the gSE measurement will take place. When the conventional mode is entered again, the synchronous channel will re-attempt the spectrum/waveform collection.

The XM-122 can produce gSE measurements only with an accelerometer. The gSE measurements are only available for the channel when Eng. Units is set to "g."

Only when both Eng. Units are not set to "g" will the XM-122 remain in conventional mode.

Overall Measurement Parameters

There are two instances of the overall measurement parameters, one for each channel. Use these parameters to configure the measurement type and the filtering performed for each overall measurement.

Overall Measurement Parameters

Parameter Name Description Values/Comments Signal Detection The measurement (or calculation) performed on the

input signal to produce the Overall Value. See Data Parameters on page 89.

• RMS - The Overall Value is the root mean squared

(RMS) signal level of the input signal.

• Calculated Peak - The Overall Value is the

measured RMS value multiplied by the square root of two (1.4142).

• Calculated Peak-to-Peak - The Overall Value is

the measured RMS value multiplied by two times the square root of two (2.8284).

• True Peak - The Overall Value is the output of a

peak detector applied to the input signal.

• True Peak-to-Peak - The Overall Value is the

output of a peak-to-peak detector applied to the input signal.

Options: RMS

Important: When changing the signal detection, make certain to check the Overall Time Constant value.

Calculated Peak Calculated Peak-to-Peak True Peak True Peak-to-Peak

Overall Time Constant For RMS measurements, the Overall Time Constant

parameter sets the 3-DB bandwidth for the digital filtering used to calculate the Overall Value. The 3-dB bandwidth is roughly equal to 1 / (2 Time Constant). The greater the Overall Time Constant, the slower the response of the measured Overall Value to change in the input signal.

For example, an Overall Time Constant of 0.1 seconds may be appropriate for monitoring the Overall Value of an input signal with a fundamental frequency of 10 Hz and above. Although, the response to a step change in input will take approximately 2.2 times the Overall Time Constant to settle. Therefore, for an Overall Time Constant of 0.1 seconds, the settling time will be approximately 0.22 seconds.

For True Peak measurements, the Overall Time Constant sets the decay rate of the peak detection meter. The greater the Overall Time Constant, the slower the Peak is decayed.

π x Overall

Enter a value greater than 0 (zero).

Recommended Value: The recommended values are appropriate for a typical 50/60 Hz machine, and may need to be adjusted depending on the application.

• For True Peak or True

the Overall Time Constant to 1.5.

An Overall Value for a measurement with a damping factor near 1.0 (critical damping) will slowly rise or fall for the full settling time specified by the Overall Time Constant before reaching the final value. An Overall Value for a measurement with a damping factor near 0.707 will rise or fall quickly and may "overshoot" (measure a value greater or less than the final value) before reaching the final value for a given input signal.

Overall Filter The filter to be applied to the overall measurement

For bands specified in Hz or CPM on an orders-based spectrum, the Band Measurement value will be zero when the Band Minimum Frequency and Maximum Frequency fall completely outside of the frequencies represented in the spectrum. If any of the band falls within the spectrum, only that portion will contribute to the Band value.

The following table shows the actual Band Minimum and Maximum Frequencies given different input speeds for this example. Note that when the speed is 10 Hz, the Band Minimum and Maximum Frequencies fall outside the range of the FMAX, so the Band value will be zero. When the speed is 20 Hz, the band will be calculated from 150 to 200 Hz.

Note: The multiplication may have the opposite of the intended effect under certain circumstances.

The Relay parameters control the operation of the on-board relay, as well as the relays on the Expansion Relay (XM-441) module. Use these parameters to configure which alarm(s) the relay is associated with, as well as the behavior of the relay.

A relay can be defined, regardless of whether or not it is physically present. A non-physical relay is a virtual relay. When a relay (physical or virtual) activates, the module sends a Change of State (COS) message to its master, which acts on the condition as necessary. An XM-440 Master Relay Module can activate its own relays in response to a relay (physical or virtual) activation at any of its slaves.

Relay Parameters

Parameter Name Description Options/Comments

Determines whether the relay is failsafe or non-failsafe.

Failsafe operation 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.

The following are true of a relay in failsafe operation:

• The relay is energized when power is applied to

the module.

• The relay in a nonalarmed condition has power

applied to the coil.

• In alarm condition, power is removed from the

relay coil, causing the relay to change state.

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.

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.

Measured values between Min Range and Max Range are scaled into the range from 4.0 to 20.0 to produce the output value. The Min Range value does not have to be less than the Max Range value. If the Min Range value is greater than the Max Range value, then the output signal is effectively inverted from the input signal.

Publication GMSI10-UM013D-EN-P - May 2010

Configuration Parameters 83

IMPORTANT

The 4-20 mA outputs are either on or off. When they are on, the 4-20 mA output overshoots the 4 and 20mA limits by 10% when the measurement exceeds the minimum and maximum range. This means the minimum current produced is 3.6 mA and the maximum current produced is 22 mA.

When the 4-20 mA outputs are off, the 4-20 mA output produces a current approximately 2.9 mA. The 4-20 mA outputs are off under the following conditions:

• The 4-20 mA outputs are set to "Disable" (see Enable above).

• The module is in Program mode.

• A transducer fault or tachometer fault occurs that affects

the corresponding measurement.

Triggered Trend Parameters

The XM-122 module can collect a triggered trend. A triggered trend is a time-based trend that is collected when a relay on the XM module is activated, or the module receives a trigger event.

Once the triggered trend is configured, the XM-122 continuously monitors the trended measurements. When a trigger occurs, the XM module collects additional data as specified by the Post Trigger parameter. The XM-122 can also store the spectrum or waveform at the time of the trigger.

The XM-122 can only store one triggered trend. Unless the triggered trend is latched, the trend data is overwritten with new data when the next trigger occurs.

The triggered trend parameters define the trend data that is collected by the module. Use these parameters to select the measurements included in the

SU/CD Trend Parameters

The XM-122 module can collect startup or coast-down trend data when the machine speed passes into a defined speed range. A tachometer input is required to collect the startup/coast-down trend.

The XM-122 collects a startup trend when the machine speed rises through the Minimum Speed + 8 RPM, and stops when the machine speed crosses either the Minimum Speed or the Maximum Speed. The module collects data only when machine speed is increasing. It does not collect data if the machine speed is constant or decreasing.

86 Configuration Parameters

IMPORTANT

The XM-122 collects a coast-down trend when the machine speed falls through the Maximum Speed - 8 RPM, and stops when the machine speed crosses either the Minimum Speed or the Maximum Speed. The module collects data when the machine speed is decreasing or increasing during the coast-down trend (for example, a coast-down restart).

The XM-122 can only store one startup/coast-down trend. Unless the startup/coast-down trend is latched, the trend data is overwritten with new data when the next trigger occurs.

The SU/CD trend parameters define the trend data that is collected by the module during the startup or coast-down of a machine. Use these parameters to configure the measurements included in the startup and coast-down trend records, the interval between trend records, and the minimum and maximum speed limits at which record collection starts and stops.
