Introducing the XM-320 Position Module

The XM-320 Position module is a 2-channel general purpose 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.

The XM-320 supports the following measurements:

• Axial Position (Thrust) - Axial position (thrust) is a measurement of

the relative position of the thrust collar to the thrust bearing. It is a measurement that may be made in both the active and inactive thrust directions. The primary purpose of this measurement is to monitor thrust bearing wear and to insure against axial rubs. It is recommended that at least two separate transducers monitor axial position so that the redundancy will give added protection.

Most steam turbine rotors operate within the total clearance between thrust shoes (float). Normally this clearance is anywhere from 0.010 to

0.024 inches. The axial measurements are obtained by mounting a non-contact probe axially, looking at the thrust collar or shaft. The sensor provides a continuous measurement of the rotor position with respect to the thrust bearing. In most applications, the thrust detector is located in close proximity to the thrust bearing, normally located in the turbine front standard.

2 Introduction

• Cam (Valve) Position - Valve position is a measurement of the main

steam inlet valve stem position. The valve position measurement provides the operator with the current load on the machine.

The amount of the steam valve opening, speed, governor, and relay valve position indication assists the operator in controlling the unit during startup and emergencies. When used in conjunction with data from other related Turbine Supervisory Instrumentation (TSI) indicators, load, or steam flow related machinery conditions can be diagnosed.

• Shell (Case) Expansion - Shell (Case) expansion is a measurement of

the thermal growth of the case from its fixed point outward. Steam temperature swings widely between startup, shutdown, and various operating conditions. The high pressure turbine end must move axially as expansion and contraction occurs. Continuous indication of shell thermal growth enables the operator to accelerate or change turbine load without excessive distortion of the machine shell.

• Differential Expansion - Differential expansion (DE) is a

measurement of the differences between the thermal growth of the rotor compared to the case.

Differential expansion monitoring provides the machine operator with continuous indication of the critical clearances between the expanding rotor and blades with respect to the expanding shell or casing. Proper coordination of machine parameters enables safe machine acceleration and operation during load changes and emergencies. To prevent axial rubs it is important that the rotor and case grow at the same rate.

Differential expansion is most important during a turbine “cold” startup. The rotor is fixed axially by the thrust bearing. The thrust bearing moves as the case expands – thus the need to monitor the difference in thermal expansion. Ideally, differential expansion should indicate zero change in the gap relationship between the two surfaces. When the shell growth leads or lags the rotor growth, or conversely the rotor expansion leads or lags the shell growth, an expansion differential occurs.

The XM-320 accepts input from linear variable differential transformers (LVDT), non-contact eddy current probes, rotary cam (valve) potentiometers, or any voltage output position measurement device.

4 Introduction

IMPORTANT

• XM-320 Position Module - Mounts on the XM-941 terminal base unit

via a keyswitch and a 96-connector. The XM-320 contains the measurement electronics, processor, relay, and serial interface port for local configuration.

The XM-441 Expansion Relay module may be connected to the XM-320 module via the XM-941 terminal base unit.

When connected to the XM-320, the Expansion Relay module simply “expands” the capability of the XM-320 by adding four additional epoxy-sealed relays. The XM-320 controls the Expansion Relay module by extending to it the same logic and functional controls as the XM-320 module’s 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

24V Common Grounding

24V power to the XM modules must be grounded. When two or more power supplies power the XM system, ground the 24V 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 24V 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 20 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 measurement modules. The XM-941 terminal base, Cat. No. 1440-TB-B, is the only terminal base unit used with the XM-320.
