If the module is installed on a DeviceNet network, configuring can also be performed using a network configuration tool such as RSNetWorx (Version 3.0 or later). Refer to your configuration tool documentation for instructions on configuring a device.
44 Configuration Parameters Channel Transducer Parameters The channel transducer parameters define the characteristics of the transducers you will be using with the module. Use the parameters to configure the transducer sensitivity, and operating range. There are two instances of the channel transducer parameters, one for each channel. TIP The Channel LED will flash red when a transducer fault condition exists on the channel even if you are not using the channel.
Configuration Parameters Measurement Parameters 45 Eccentricity Measurement Parameters Use these parameters to configure the engineering units and update rate for the eccentricity measurements. There are two instances of the eccentricity measurement parameters, one for each channel. TIP The Eccentricity Update Rate parameter is for installations where the tachometer signal is not available.
46 Configuration Parameters The Waveform Period and the Number of Points must be configured such that the sampling rate (Number of Points/Waveform Period) is from 0.32 Hz to 187.5 Hz. The module will automatically use 187.5 Hz when the sampling rate is above 93.75, resulting in waveforms collected with a different period than specified. TIP The table below shows examples.
Configuration Parameters 47 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).
48 Configuration Parameters Tachometer Signal Processing Parameters IMPORTANT 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. Tachometer Signal Processing Parameters Parameter Name Description Values/Comments Pulses Per Revolution The number of tachometer signal pulses per revolution of the shaft (number of gear teeth).
Configuration Parameters 49 Tachometer Signal Processing Parameters Parameter Name Description Values/Comments 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. Alarm Parameters The Alarm parameters control the operation of the alarms (alert and danger level) and provide alarm status. The Eccentricity module provides two alarms, one per eccentricity channel.
50 Configuration Parameters Alarm Parameters Parameter Name Description Values/Comments Condition Controls when the alarm should trigger. Options: Greater Than Less Than Inside Range Outside Range • Greater than - Triggers the alarm when the measurement value is greater than or equal to the Alert and Danger Threshold values. The Danger Threshold value must be greater than or equal to the Alert Threshold value for the trigger to occur.
Configuration Parameters 51 Alarm Parameters Parameter Name Description Values/Comments Alert Threshold (High) The threshold value for the alert (alarm) condition. Same measurement unit as the Eccentricity Unit selection for the specified channel. 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.
52 Configuration Parameters 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 This parameter is not used when Speed Range Enabled is disabled. Speed Range High The greater threshold of the machine speed range. This value must be greater than the Speed Range Low value. This parameter is not used when Speed Range Enabled is disabled.
Configuration Parameters 53 Relay Parameters Parameter Name Description Options/Comments Name (XM Serial Configuration Utility only) A descriptive name to help identify the relay in the XM Serial Configuration Utility. Maximum 18 characters Enable Enable/disable the selected relay. Note: The Relay Current Status is set to "Not Activated" when the relay is disabled. See page 57.
54 Configuration Parameters 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.
Configuration Parameters 55 Relay Parameters Parameter Name Description XM Configuration EDS File Utility Failsafe Relay Failsafe Option 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.
56 Configuration Parameters IMPORTANT IMPORTANT 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. The 4-20 mA outputs are either on or off.
Configuration Parameters 57 I/O Data Parameters Parameter Name Description Values/Comments COS Output (XM Serial Configuration Utility only) The Assembly instance used for the COS message. The COS message is used to produce the Alarm and Relay status for the module. The COS Output cannot be changed. Refer to COS Message Format on page 73 for more information. Poll Size Sets the size (number of bytes) of the Poll response The minimum size is 4 bytes and the message.
58 Configuration Parameters Monitor Data Parameters Monitor Data Parameters Parameter Name Description Values/Comments Channel Status (XM Serial Configuration Utility only) States whether a fault condition exists on the associated channel. If a fault exists, the eccentricity measurement may not be accurate.
Configuration Parameters 59 Alarm and Relay Status Parameters Alarm and Relay Status Parameters Parameter Name XM Configuration EDS File Utility Alarm Relay Status Description Values/Comments States the current status of the alarm. Possible status values: • Normal - The alarm is enabled, the device is in Run mode, there is no transducer fault, and the current measurement is not within the Alert or Danger Threshold value(s).
60 Configuration Parameters Device Mode Parameters The Device Mode parameters are used to control the functions and the behavior of the device. IMPORTANT The XM Serial Configuration Utility handles these parameters automatically and transparently to the user. Device Mode Parameters Parameter Name Description Values/Comments Device Mode Sets the current operation mode of the device. Refer to Changing Operation Modes on page 67 for more information.

74 DeviceNet Information XM Status Values The following tables describe the XM Status values that are included in the COS messages.
DeviceNet Information 75 • The ADR scanner can not download the configuration data to an XM module if the module has a saved configuration in its non-volatile memory. This happens because the saved configuration is restored and the module enters Run mode when the power is cycled. (Configuration parameters cannot be downloaded while an XM module is in Run mode.) XM modules must be in Program mode for the ADR configuration to be downloaded and this occurs only when there is no saved configuration.
76 DeviceNet Information – All SU/CD Trend related parameters – Custom Assembly structure (see page 56) • The ADR and trigger group functions cannot be used together. A module can have only one primary master so a module cannot be both configured for ADR and included in a trigger group. The ADR scanner must be the primary master for the modules configured for ADR. The XM-440 Master Relay module must be the primary master for modules included in a trigger group.

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. Automatic Device Replacement (ADR) A means for replacing a malfunctioning device with a new unit, and having the device configuration data set automatically. The ADR scanner uploads and stores a device’s configuration.
Glossary 116 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.
Glossary 117 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. MAC ID See node address. master device A device which controls one or more slave devices. The XM-440 Master Relay module is a master device. Node Address A DeviceNet network can have as many as 64 devices connected to it.
Glossary 118 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.
