Introduction

This chapter provides an overview of the XM-120 Eccentricity module. It also discusses the components of the module.

For information about See page

Introducing the Eccentricity Module 1 Eccentricity Module Components 2 Using this Manual 3

This manual only describes how to install and use the XM-120 Eccentricity module. For information about the dynamic measurement and low frequency dynamic measurement modules, refer to the XM-120/121 Dynamic Measurement Module User Guide.

Introducing the Eccentricity Module

The XM-120 Eccentricity module is a 2-channel eccentricity monitor. It is a

member of the Allen-Bradley™ XM condition monitoring and protection modules that operate both in stand-alone applications or integrate with Programmable Logic Controllers (PLCs) and control system networks.

Eccentricity is the measure of the amount of bow in a rotor. The lower the eccentricity value the more straight the shaft. Rotor bow can be a fixed mechanical bow, or it can be a temporary bow caused by uneven thermal heating or simply by the weight of the rotor (gravity bow).

The Eccentricity module is suitable for virtually all types of rotating and reciprocating machinery where rotor bow must be measured prior to or during startup. It accepts input from non-contact eddy current probe systems to provide peak-to-peak eccentricity, maximum instantaneous DC voltage (max gap), minimum instantaneous DC voltage (min gap), and instantaneous DC voltage (gap) measurements. In addition to the transducer inputs, the module can accept one tachometer input to provide speed measurement, which can, if desired, be used to disable eccentricity alarms after startup.

The Eccentricity module includes a single on-board relay, expandable to five, making it a complete monitoring system. It 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, distributed control systems (DCS), and Condition Monitoring Systems.

The Eccentricity module 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.

Eccentricity Module Components

The Eccentricity module consists of a terminal base unit and an instrument module. The XM-120 Dynamic Measurement Module and the XM-940 Terminal Base are shown below.

Figure 1.1 Eccentricity Module Components

• XM-940 Dynamic Measurement Module Terminal Base - A DIN rail

mounted base unit that provides terminations for all field wiring required by XM Dynamic Measurement and Eccentricity modules.

Publication GMSI10-UM010C-EN-P - May 2010

• XM-120 Dynamic Measurement Module - The XM-120 mounts on the

XM-940 terminal base via a keyswitch and a 96-pin connector. The XM-120 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-120 module via the XM-940 terminal base.

When connected to the module, the Expansion Relay module simply “expands” the capability of the XM-120 by adding four additional epoxy-sealed relays. The module 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.

12 Installing the XM-120 Eccentricity Module

IMPORTANT

24V 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 Eccentricity module.

IMPORTANT

ATTENTION

Connecting the Power Supply

Power supplied to the module must be nominally 24 Vdc (±10%) and must be a Class 2 rated circuit.

Wire the DC-input power supply to the terminal base unit as shown in Figure

2.8.

Figure 2.8 DC Input Power Supply Connections

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.

The power connections are different for different XM modules. Refer to the installation instructions for your specific XM module for complete wiring information.

22 Installing the XM-120 Eccentricity Module

IMPORTANT

TIP

IMPORTANT

Connecting the Relays

The XM-120 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 52 for details.

Table 2.1 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 (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-120 provides a single tachometer input signal. The signal processing performed on the tachometer signal depends on the configuration of the

module. See page 47 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.

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-120.

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 2.19.

ATTENTION

Connecting the 4-20 mA Outputs

The module includes an isolated 4-20 mA per channel output into a maximum load of 300 ohms. The measurements that the 4-20 mA output tracks and the signal levels that correspond to the 4 mA and 20 mA are configurable. Refer to 4-20 mA Output Parameters on page 55 for details.

Wire the 4-20 mA outputs to the terminal base unit as shown in Figure 2.21.

Figure 2.21 4-20mA Output Connections

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.

Serial Port Connection

The XM-120 includes a serial port connection that allows you to connect a PC to it and configure the module’s parameters. There are two methods of connecting an external device to the module’s serial port.

• Ter mi na l Ba s e U n it - There are three terminals on the terminal base

unit you can use for the serial port connection. They are TxD, RxD, and RTN (terminals 7, 8, and 9, respectively). If these three terminals are wired to a DB-9 female connector, then a standard RS-232 serial cable with 9-pin (DB-9) connectors can be used to connect the module to a PC (no null modem is required).

• Mini Connector - The mini connector is located on the top of the

module, as shown below.

Figure 2.22 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.

IMPORTANT

ATTENTION

DeviceNet Connection

The XM-120 includes a DeviceNet™ connection that allows the module to communicate with a programmable controller, 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-120. As multiple XM modules are interconnected, DeviceNet also serves as the communication bus and protocol that efficiently transfers data between the XM modules.

Connect the DeviceNet cable to the terminal base unit as shown.

Connect To Terminal

Red Wire DNet V+ 26 (optional—see note) White Wire CAN High 23 Bare Wire Shield (Chassis) 10 Blue Wire CAN Low 24 Black Wire DNet V- 27

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.

ATTENTION

IMPORTANT

ATTENTION

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).

The devices are shipped from the factory with the network node address (MAC ID) set to 63. The network node address is software settable. You can use the XM Serial Configuration Utility or RSNetWorx™ for DeviceNet (Version 3.0 or later) to set the network node address. Refer to the appropriate documentation for details.

Mounting the Module

The baud rate for the XM-120 is set by way of “baud detection” (Autobaud) at power-up.

The XM-120 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-120 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 modules.

Do not attempt to install XM-120 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.

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.

4-20 mA Output Parameters

4-20 mA Parameters

Parameter Name Description Options/Comments Enable Enables/disables the 4-20 mA output.

Min Range The measured value associated with the 4 mA. Same measurement unit as the Max Range The measured value associated with the 20 mA.

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.

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.

Publication GMSI10-UM010C-EN-P - May 2010

56 Configuration Parameters

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. 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).

I/O Data Parameters

• The module is in Program mode.

• A transducer fault or tachometer fault occurs that affects

the corresponding measurement.

The I/O data parameters are used to configure the content and size of the DeviceNet I/O Poll response message.

The XM-120 must be free of Poll connections when configuring the Poll Output (Poll Response Assembly) and Poll Size. Any attempt to download the parameters while a master device has established the Poll connection with the Eccentricity module will result in an error.

To close an existing Poll connection with an XM-440, switch the XM-440 from Run mode to Program mode. Refer to Changing Operation Modes on page 67.

To close an existing Poll connection with other master devices, remove the module from the scan list or turn off the master device.

DeviceNet Information

IMPORTANT

Appendix

Electronic Data Sheets

Changing Operation Modes

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. The latest EDS files can also be obtained at http://www.ab.com/networks/eds/ or by contacting your local Rockwell Automation representative.

Refer to your DeviceNet documentation for instructions on registering the EDS files.

XM modules operate in two modes.

Mode Description

Run The XM measurement modules collect measurement data and

monitor each measurement device. The XM-440 establishes I/O connections with the XM measurement modules in its scan list and monitors their alarms, and controls its own relay outputs accordingly.

Program The XM module is idle.

The XM measurement modules stop the signal processing/measurement process, and the status of the alarms is set to the disarm state to prevent a false alert or danger status. The XM-440 closes the I/O connections with the XM measurement modules in its scan list and stops monitoring their alarms, relays are deactivated unless they are latched. Configuration parameters can be read, updated and downloaded to the XM module.

To change the operation mode of the module, use the Device Mode parameter in the EDS file. Note that the Stop and Start services described on page 69 can also be used to change the operation mode.

The XM Serial Configuration Utility software automatically puts XM modules in Program mode and Run mode without user interaction.

TIP

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.

The Module Status indicator flashes green when the module is in Program mode.

Refer to your DeviceNet documentation for specific instructions on editing EDS device parameters.

You can also use the Stop service described on page 69 to transition XM modules to Program mode.

Transition to Run Mode

In order to collect data and monitor measurement devices, XM modules must be in Run mode. To transition an XM module from Program mode to Run mode on a DeviceNet network, set the Device Mode parameter to "Run mode" and click Apply.

The Module Status indicator is solid green when the module is in Run mode.

Refer to your DeviceNet documentation for specific instructions on editing EDS device parameters.

Poll Message Format

The Eccentricity module Poll request message contains no data. The Poll response message can contain up to 31 REAL values for a total of 124 bytes.

The Eccentricity module provides four pre-defined (static) data formats of the Poll response, as defined in Assembly instance 101–104. It also provides a dynamic Assembly instance, instance 199, with which you can define a custom data format for the Poll response. The dynamic Assembly instance can contain any of the measurement parameters included in Assembly instance 101, as well as several of the alarm and relay configuration parameters.

The default Assembly instance is 101 and the default size is 36 bytes. You can change the Assembly instance and define the custom Assembly instance using the configuration software. Refer to I/O Data Parameters on page 56 for details.

Relay Status Value Description

0 Not Activated 1 Activated

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.

It is recommended that ADR not be used in safety related applications. If the failure of the ADR server, and a subsequent power cycle, would result in the loss of protection for a machine, then ADR should not be implemented.

ADR can be used with XM modules but keep the following in mind when setting up the XM modules.

Publication GMSI10-UM010C-EN-P - May 2010

DeviceNet Information 75

TIP

• 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.

To delete a saved configuration from non-volatile memory, use the Delete service in RSNetWorx for DeviceNet or perform the following steps in the XM Serial Configuration Utility.

1. Save the current configuration to a file. From the File menu, click Save As and enter a file name for

the configuration.

2. Reset the module to factory defaults. Click the Module tab and click the Reset button.

3. Reload the saved configuration. From the File menu, click Open and select the configuration file.

4. Make certain to disable auto save. From the Device

menu, clear the Auto Save Configuration check mark.

• An XM module will enter Run mode automatically after the ADR

scanner restores the module’s configuration only if the module is in Run mode at the time the configuration is saved to the scanner. If the module is in Program mode when the configuration is saved, then the module will remain in Program mode after the configuration is downloaded by the ADR scanner.

• 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.

– Channel Name

– Tachometer Name

– Alarm Name

– Relay Name

– All Triggered Trend related parameters

Publication GMSI10-UM010C-EN-P - May 2010

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.

• 2 = 500 kbps

The Baud Rate setting is used only when automatic baud rate detection is disabled (Autobaud Disable = 1). When Autobaud Disable is set to zero (0), the module ignores its Baud Rate setting and performs automatic baud
