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

Introducing the Absolute Shaft Module

The XM-121 Absolute Shaft module is an XM-121 Low Frequency Dynamic module with alternative, XM-121A, firmware loaded onto it. The XM-121 is

part 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.

Shaft Absolute is the measure of the shaft’s motion relative to free space – its absolute motion. In the Absolute Shaft module, the Shaft Absolute measurement is calculated by summing signals of both an eddy current probe, measuring the motion of the shaft relative to the case, and an Allen-Bradley 9000 series sensor (accelerometer or velocity) measuring the absolute motion of the case.

In addition to vibration inputs, the Absolute Shaft module accepts one tachometer input to provide speed measurement and order analysis functions. It also includes a single on-board relay (expandable to five with an XM-441 module), two 4-20 mA outputs, and a buffered output for each input. The module can collect data under steady-state and startup/coast-down conditions, and monitor up to nine alarms making it a complete monitoring system.

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 Absolute Shaft Module

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.

To Ground Bus

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 Absolute Shaft module.

24V dc Power Supply

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.

Connecting the Relays

The XM-121 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.

Publication GMSI10-UM014D-EN-P - May 2010

22 Installing the Absolute Shaft Module

IMPORTANT

TIP

IMPORTANT

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 59 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 table 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’s 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.
