10 Figure 2.3 DIN Rail Grounding Block Panel/Wall Mount Grounding The XM modules can also be mounted to a conductive mounting plate that is grounded. See Figure 2.5. Use the grounding screw hole provided on the terminal base to connect the mounting plate the Chassis terminals. Figure 2.
11 Figure 2.5 Panel/Wall Mount Grounding 1 Power Supply 1 Power Supply 1 Use 14 AWG wire.
12 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. IMPORTANT IMPORTANT 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.
13 Figure 2.6 Grounded DeviceNet V- at XM Module To Ground Bus ATTENTION 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. 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).
14 The terminal base can be DIN rail or wall/panel mounted. Refer to the specific method of mounting below. ATTENTION The XM modules make a chassis ground connection through the DIN rail. Use zinc plated, yellow chromated steel DIN rail 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. You can also mount the terminal base to a grounded mounting plate.
15 3. Rotate the terminal base onto the DIN rail with the top of the rail hooked under the lip on the rear of the terminal base. 4. Press down on the terminal base unit to lock the terminal base on the DIN rail. If the terminal base does not lock into place, use a screwdriver or similar device to open the locking tab, press down on the terminal base until flush with the DIN rail and release the locking tab to lock the base in place.
16 5. Gently push the side connector into the side of the neighboring terminal base to complete the backplane connection. Panel/Wall Mounting Installation on a wall or panel consists of: • laying out the drilling points on the wall or panel • drilling the pilot holes for the mounting screws • installing the terminal base units and securing them to the wall or panel Use the following steps to install the terminal base on a wall or panel.
17 1. Lay out the required points on the wall/panel as shown in the drilling dimension drawing below. Side Connector 2. Drill the necessary holes for the #6 self-tapping mounting screws. 3. Secure the terminal base unit using two #6 self-tapping screws. 4. To install another terminal base unit, retract the side connector into the base unit. Make sure it is fully retracted. 5. Position the terminal base unit up tight against the neighboring terminal base.

21 Figure 2.8 DC Input Power Supply Connections 24V dc Power Supply IMPORTANT IMPORTANT ATTENTION + - - A Class 2 circuit can be provided by use of an NEC Class 2 rated power supply, or by using a SELV or PELV rated power supply with a 5 Amp current limiting fuse installed before the XM module(s). 24Vdc needs to be wired to terminal 44 (+24 V In) to provide power to the device and other XM modules linked to the wired terminal base via the side connector.
22 Table 2.1 shows the on-board relay connections for the XM-123. IMPORTANT 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.
23 Figure 2.9 Relay Connection - Failsafe, Nonalarm Condition Non-failsafe, Alarm Condition Figure 2.10 Relay Connection - Failsafe, Alarm Condition Non-failsafe, Nonalarm Condition Alternate Relay Wiring Figures 2.11 and 2.12 illustrate how to wire both ends of a single external indicator to the XM terminal base for failsafe, nonalarm or alarm condition or non-failsafe, nonalarm or alarm condition.
24 Figure 2.11 Relay Connections for De-energized Relay Circuit Figure 2.12 Relay Connection - Failsafe, Alarm Condition Non-failsafe, Nonalarm Condition Connecting the Tachometer Signal The XM-123 provides a single tachometer input signal. The signal processing performed on the tachometer signal depends on the configuration of the module. See page 57 for a description of the tachometer parameters.
25 Connecting a Magnetic Pickup Tachometer Figure 2.13 shows the wiring of a magnetic pickup tachometer to the terminal base unit. Figure 2.13 Magnetic Pickup Tachometer Signal Connection Connecting a Hall Effect Tachometer Sensor Figure 2.14 shows the wiring of a Hall Effect Tachometer Sensor, Cat. No. EK-44395, to the terminal base unit. Figure 2.
26 Connecting a Non-Contact Sensor to the Tachometer Signal Figure 2.15 shows the wiring of a non-contact sensor to the tachometer input signal. Figure 2.15 Non-Contact Sensor to Tachometer Signal Connection 4 18 Signal Common 20 21 31 Tach Input Signal -24V DC -24 SIG COM S hi e ld F lo a t i n g S h i el d Isolated Sensor Driver Connecting the Buffered Outputs The XM-123 provides buffered outputs of all transducer input signals.
27 Figure 2.16 Buffered Output Connections IMPORTANT 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) to either terminal 6 (Positive Buffer Bias) or terminal 21 (Buffer -), depending on the transducer. See Table 2.2. The buffered output operating range is configured independently per channel. Table 2.
28 Connecting an IEPE Accelerometer The following figures show the wiring of an IEPE accelerometer to the terminal base unit. ATTENTION IMPORTANT IMPORTANT You may ground the cable shield at either end of the cable. Do not ground the shield at both ends. Recommended practice is to ground the cable shield at the terminal base and not at the transducer. Any convenient Chassis terminal may be used (see Terminal Block Assignments on page 18).

31 Connecting a Passive Transducer The figures below show the wiring of a passive transducer, such as a velocity sensor, to the terminal base unit. ATTENTION IMPORTANT You may ground the cable shield at either end of the cable. Do not ground the shield at both ends. Recommended practice is to ground the cable shield at the terminal base and not at the transducer. Any convenient Chassis terminal may be used (see Terminal Block Assignments on page 18). The module does not power the sensor.

33 ATTENTION Figures 2.23 and 2.24 show the wiring of a Model 580 Vibration Pickup, which is a +24V transducer. The +24V sensors powered from pin 25 do not utilize the redundant power connection to the XM-123. So if primary 24V power is lost, the +24V sensor will lose power regardless of whether the XM-123 remains powered through the redundant power terminals. If redundant power is required then use a redundant power supply (Allen-Bradley 1606-series is recommended). Figure 2.

35 IMPORTANT A jumper from terminal 5 to terminal 6 is required for channel 1 buffered output. A jumper from terminal 22 to terminal 21 is required for channel 2 buffered output. Refer to Configuring Buffered Output Input Range on page 27. Figure 2.
36 IMPORTANT IMPORTANT IMPORTANT Make certain the IEPE Power parameter is enabled for both channel 1 and channel 2 so power is provided to the accelerometers. Refer to Channel Transducer Parameters on page 50. Transducer DC bias is monitored on all signals. A jumper from terminal 5 to terminal 6 is required for channel 1 buffered output. A jumper from terminal 22 to terminal 6 is required for channel 2 buffered output. Refer to Configuring Buffered Output Input Range on page 27. Figure 2.
37 Connecting a Velocity Sensor and Two Non-Contact Sensors Figure 2.27 shows the wiring of a velocity sensor and two non-contact sensors to the terminal base unit of the XM-123. The velocity sensor is wired to channel 1. The first non-contact sensor is wired to channel 2, and the other non-contact sensor is wired to the tachometer input signal. ATTENTION IMPORTANT IMPORTANT You may ground the cable shield at either end of the cable. Do not ground the shield at both ends.
38 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-123.
39 A single switch contact can also be shared by multiple XM modules wired in parallel as shown in Figure 2.29. ATTENTION The relay reset connections may be different for different XM modules. Figure 2.29 applies only to the XM-123 module. Refer to the installation instructions for the module for its terminal assignments. Figure 2.
40 Figure 2.30 Setpoint Multiplication Connection ATTENTION 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.
41 Figure 2.31 4-20 mA Output Connections - ATTENTION The 4-20 mA outputs are functionally isolated from other circuits. It is recommended that the outputs be grounded at a single point. Connect the 4-20 mA (-) to the XM terminal base (Chassis terminal) or directly to the DIN rail, or ground the signal at the other equipment in the 4-20 mA loop. PC Serial Port Connection The XM-123 includes a serial port connection that allows you to connect a PC to it and configure the module’s parameters.
42 • Mini-Connector - The mini-connector is located on the top of the module, as shown below. Figure 2.32 Mini-Connector 1440-VAD02-01RA AERODERIVATIVE mini-connector A special cable (Cat.

Very High HPF Frequency (EDS File only) Shows the corner frequency for the Very High high pass filter option.
54 Overall Measurement Parameters Parameter Name Description Values/Comments 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 / (2π x Overall Time Constant). The greater the Overall Time Constant, the slower the response of the measured Overall Value to change in the input signal. Enter a value greater than 0 (zero).
55 Aeroderivative Measurement Parameter The aeroderivative measurement parameter determines which filter measurement (tracking or bandpass) is performed by the channel. There are two instances of the aeroderivative measurement parameters, one for each channel. Aeroderivative Measurement Parameter Parameter Name Description Values/Comments Tracking Filter The tracking filter adjusts the high and low pass filters to form a band pass filter centered at the machine speed.

Hz Constant Q The ratio of the bandwidth to the center frequency (machine speed) remains the same. Q Enter the Q value for the Constant Q filter. Q is the measure of the sharpness of a filter Note: This value is used or enabled only when Constant Bandwidth is selected as the tracking filter type.
57 Speed Measurement Parameter Use the speed measurement parameter to configure the filtering performed on the speed measurement. Speed Measurement Parameter Parameter Name Description Values/Comments Exponential Averaging Time Constant Sets the 3-dB bandwidth for the digital filter used to calculate the Speed Value. The 3-dB bandwidth is roughly equal to 1 / (2π x Exponential Averaging Time Constant).
58 Tachometer Transducer Parameters Parameter Name Description Values/Comments Fault Low The minimum, or most negative, expected DC voltage from the transducer. Volts Note: A voltage reading outside this range constitutes a transducer fault. Fault High The maximum expected DC voltage from the transducer. DC Bias Time Constant The time constant used for exponential averaging Seconds (low pass filtering) of the transducer DC bias measurement.
59 Tachometer Signal Processing Parameters IMPORTANT The tachometer is required for the tracking measurement and the speed measurement. If you are not using the tachometer channel, set the Pulses Per Revolution to zero. This will disable the tachometer measurement, and prevent the module from indicating a tachometer fault.
60 Tachometer Signal Processing Parameters Parameter Name Description Values/Comments Trigger Threshold The signal level to be used as the trigger value when in Manual Trigger mode. Enter a value from +16 to -16 volts dc. Note: This value is not used in Auto Trigger mode. Trigger Slope The input signal slope to be used as the trigger value when in Manual Trigger mode. Options: Positive Negative Note: This value is not used in Auto Trigger mode.
61 Alarm Parameters Parameter Name Description Values/Comments Measurement The type of measurement and the channel that is associated with the alarm. Options: Ch1 / Ch2 Overall Ch1 / Ch2 Tracking Magnitude * Ch1 / Ch2 Band * Speed Ch1 / Ch2 DC Bias Important: The tracking and band measurement selections depend on which filter measurement (Bandpass Filter or Tracking Filter) is selected. See Aeroderivative Measurement Parameter on page 55.
62 Alarm Parameters Parameter Name Description Alert Threshold (High) The threshold value for the alert (alarm) condition. Values/Comments Note: This parameter is the greater threshold value when Condition is set to "Inside Range" or "Outside Range." Danger Threshold (High) The threshold value for the danger (shutdown) condition. Note: This parameter is the greater threshold value when Condition is set to "Inside Range" or "Outside Range.
63 Alarm Parameters Parameter Name Description Values/Comments Threshold Multiplier The action to take when the setpoint multiplier switch is closed (push button engaged or toggle switch flipped to on) and during the startup period once the switch is reopened. The module applies the multiplier to the alarm thresholds during this time to avoid false alarms at resonance frequencies. Enter a floating point value in the range of 0 to 10. Enter 0 (zero) to disabled the alarm during the startup period.
64 Alarm Parameters Parameter Name Description Values/Comments Speed Range Low The lesser threshold of the machine speed range. This value must be less than the Speed Range High value. RPM The greater threshold of the machine speed range. This value must be greater than the Speed Range Low value. RPM Speed Range High Relay Parameters Note: This parameter is not used when Speed Range Enabled is disabled. Note: This parameter is not used when Speed Range Enabled is disabled.
65 Relay Parameters Parameter Name Description Enable Enable/disable the selected relay. Options/Comments Note: The Relay Current Status is set to "Not Activated" when the relay is disabled. See page 78.
66 Relay Parameters Parameter Name XM Configuration EDS File Utility Alarm Status to Activate On Description Options/Comments Sets the alarm conditions that will cause the relay to activate. You can select more than one. Options: Normal Danger Xdcr Fault Tacho Fault Alert Disarm Module Fault Alarm Levels • Normal - The current measurement is not within excess of any alarm thresholds.
67 Relay Parameters Parameter Name Description XM Configuration EDS File Utility Failsafe Relay Failsafe Option 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.
68 4-20 mA Output Parameters The 4-20 mA output parameters define the characteristics of the two 4-20 mA output signals. The parameters are the same for each output. 4-20 mA Parameters Parameter Name Description Enable Enables/disables the 4-20 mA output. Measurement Options/Comments Sets the type of measurement and the channel that the 4-20 mA output signal will track.
69 IMPORTANT The 4-20 mA outputs are either on or off. When they are on, the 4-20 mA outputs overshoot the 4 and 20 mA 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, they produce 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 on the previous page).
70 Triggered Trend Parameters Parameter Name Description Values/Comments Enable Triggered Trend Measurements Enables/disables the triggered trend measurements. Select to configure the triggered trend measurements. Check to enable. Clear to disable. Select Measurements Sets the measurements to be collected and stored in the module. More than one measurement can be selected. Important: Make certain to check your filter selection (Tracking Filter or Bandpass Filter).
71 Triggered Trend Parameters Parameter Name Description Values/Comments Record Interval The amount of time between consecutive trend records. 1 to 3600 seconds Note: If you enter a Record Interval, the Trend Span is automatically updated. Trend Span Seconds The total amount of time that can be covered by the trend data (Number of Records x Record Interval). Note: If you edit the Trend Span, the Record Interval is automatically updated.
72 The XM module 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 a coast-down trend (for example, a coast-down restart). The XM-123 can only store one startup/coast-down trend.
73 SU/CD Trend Parameters Parameter Name Description Values/Comments Latch Enable Determines whether the startup/coast-down trend is Check means latched Clear means unlatched latched or unlatched. Latched means that subsequent startup/coast-down trends are ignored after the initial startup/coast-down.

Appendix B DeviceNet Information Electronic Data Sheets Electronic Data Sheet (EDS) files are simple text files used by network configuration tools such as RSNetWorx (Version 3.0 or later) to help you identify products and easily commission them on a network. The EDS files describe a product’s device type, product revision, and configurable parameters on a DeviceNet network. The EDS files for the XM modules are installed on your computer with the XM configuration software.
90 Transition to Program Mode Parameter values can only be downloaded to an XM module while the module is in Program mode. Any attempt to download a parameter value while the module is in Run mode will result in a Device State Conflict error. To transition an XM module from Run mode to Program mode on a DeviceNet network, set the Device Mode parameter to "Program mode" and click Apply. Note that you cannot change any other parameter until you have downloaded the Program mode parameter.
91 The table below defines the services supported by the XM modules. The table includes the service codes, classes, instances, and attributes by their appropriate hexadecimal codes. Use the Class Instance Editor in RSNetWorx to execute these services, as illustrated in the example below.
92 Example To save the configuration parameters to the non-volatile memory (EEPROM), fill in the Class Instance Editor as shown below. Clear Send the attribute ID and then enter the Class (320 hex) and Instance (1) Select the Save service code Click Execute to initiate the action Invalid Configuration Errors A Start or Save service request to an XM module may return an Invalid Device Configuration error when there is a conflict amongst the configuration settings.
93 Additional Error Codes returned with the Invalid Device Configuration Error (0xD0) XM-123 I/O Message Format Error Code (Hex) Description 0A Too many alarms associated with a single measurement. 0B Invalid node address in the alarm list. 0C Too many alarms in the alarm list. Or, no alarms in the alarm list. 0D Alarm levels cannot be zero for alarms that are enabled. 0E Too many slaves in the scanner’s input data table.
94 The Poll response data can also be requested explicitly through Assembly Object (Class ID 0x4), Instance 101 (0x65), Data Attribute (3). The following tables show the static data format of Assembly instance 101 and 102.
95 COS Message Format The XM-123 COS message contains six bytes of data as defined in the table below. The COS data can also be requested explicitly through Assembly Object (Class ID 0x4), Instance 100 (0x64), Data Attribute (3).
96 Relay Status Descriptions Relay Status Value Description 0 Not Activated 1 Activated Bit-Strobe Message Format The Bit-Strobe command sends one bit of output data to each XM slave whose node address appears in the master’s scanlist. The Bit-Strobe command message contains a bit string of 64 bits (8 bytes) of output data, one output bit per node address on the network. One bit is assigned to each node address supported on the network (0...63) as shown in Figure B.1. Figure B.
97 ADR for XM Modules Automatic Device Replacement (ADR) is a feature of an Allen-Bradley DeviceNet scanner. It provides a means for replacing a failed device with a new unit, and having the device configuration data set automatically. Upon replacing a failed device with a new unit, the ADR scanner automatically downloads the configuration data and sets the node address. IMPORTANT It is recommended that ADR not be used in safety related applications.
98 • The ADR scanner saves and restores only the configuration parameters contained in the module’s EDS file. Some XM parameters are not included in the EDS file because they are not supported by either the EDS specification or the tools that read the EDS files, for example RSNetWorx for DeviceNet. These configuration parameters will not be restored with ADR. Below is a list of the configuration parameters that are not included in the EDS file and can not be saved or restored with ADR.

Appendix D Guidelines for Setting the Full Scale Value Appendix D provides tables to help you determine the optimal value to use for the Full Scale setting in the XM-123 module. The signal conditioning circuitry in the modules adjusts its dynamic range based upon the value entered in this setting. The full scale value is a voltage level that is dependent upon your monitoring application and other XM configuration settings.
144 Use the following tables to help you determine the optimal Full Scale value for the XM-123 module. Refer to the table that corresponds to the units of vibration that will be used for monitoring. XM-123 Full Scale Tables Table D.1 XM-123 Measuring Acceleration with Accelerometer (100 mV/g) Max Vibration Level Full Scale Setting g’s peak 1Hz HPF 5Hz HPF 10Hz HPF 1 0.1 5 0.75 10 1 30 3 40 4 50 5 40Hz HPF 1000Hz HPF Table D.
