Chapter 1 Introduction This chapter provides an overview of the XM Electronic Overspeed Detection System. It also discusses the components of the Electronic Overspeed Detection System.
Introduction The XM EODS is comprised of the following components: • Two Allen-Bradley™ 1606-XLP30E Power Supplies - The two power supply modules (85 - 264 VAC input, +24V DC output) provide redundant power to the EODS. Each power supply is independently capable of supplying power for the entire system. If one of the power supply modules fails, the system will continue to operate properly.
Introduction 9 The XM EODS can operate stand-alone, or it can be deployed on a standard or dedicated DeviceNet network where it can provide real-time data and system information to other XM modules, Programmable Logic Controllers (PLCs), distributed control systems (DCS), and Condition Monitoring Systems. XM Module Components The XM modules in the XM EODS consist of a terminal base and an instrument module. The instrument module and terminal base for the XM-220 and XM-442 is shown below.

Installing the XM Electronic Overspeed Detection System Figure 2.5 Panel/Wall Mount Grounding 1 Power Supply 1 Power Supply 1 Publication GMSI10-UM015B-EN-E - June 2011 Use 14 AWG wire. If it is desired to isolate the power supply because of possible ground loops, do not connect 24V Common to earth as illustrated in Figure 2.2. When the 24V supply is isolated from earth, it is recommended to use an isolator on the RS-232 lines. Refer to the XM-220 Dual Speed Module User Guide.
Installing the XM Electronic Overspeed Detection System 19 24V Common Grounding It is recommended that all 24V power to the XM modules is 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. For applications where redundant power supplies are used, only one power supply needs to be grounded. The XM module ties the two 24V Common lines together. IMPORTANT The 24V Common and Signal Common terminals are internally connected.
Installing the XM Electronic Overspeed Detection System Mounting the Terminal Base Units 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-220 module. • The XM-946 terminal base, Cat. No. 1440-TB-G, is the only terminal base unit used with the XM-442 module. The terminal base can be DIN rail or wall/panel mounted.

Installing the XM Electronic Overspeed Detection System 29 Typical XM EODS Wiring Diagram Figure 2.7 shows the typical XM Electronic Overspeed Device System wiring configuration. See the following topics for specific wiring information. Figure 2.
Installing the XM Electronic Overspeed Detection System Connecting the Primary Power Supply The primary 24V dc needs to be wired to terminal 0 (24V In 1) on the XM-442 terminal base to provide power to the XM-442 and the other XM-220 modules. Wire the primary power supply to the XM-442 terminal base unit as shown in Figure 2.8. Then place a jumper between terminals 0 and 16 so that the XM-442 can monitor the EODS primary power supply module. Figure 2.
Installing the XM Electronic Overspeed Detection System 31 Connecting the Secondary Power Supply The secondary (redundant) power supply needs to be wired to all of the XM modules in the XM EODS. Wire the secondary power supply to the XM modules as shown in Figure 2.9. Then place a jumper between terminals 3 and 34 on the XM-442 terminal base to enable the XM-442 to monitor the EODS secondary power supply. ATTENTION The power connections are different for the XM-220 and XM-442 modules. Figure 2.
Installing the XM Electronic Overspeed Detection System Connecting the Overspeed/Circuit Fault Signals The XM-442 module accepts one discrete digital input signal from each of the three XM-220 modules. If the XM-220 detects an overspeed condition or a circuit fault condition (failure of a sensor connected to, or logic device in, the XM-220), it will activate this signal. The 1-out-of-3 or 2-out-of-3 voting logic is determined by the number of active overspeed/circuit fault signals.
Installing the XM Electronic Overspeed Detection System 33 Wiring the XM-442 Relays There are four normally energized (failsafe) relays in the XM-442 module. Three relays serve as the shutdown relays. The fourth relay is the alarm relay. The shutdown relays will be activated by any of the following conditions: • Overspeed condition on any two (or all three) of the three XM-220 channels.
Installing the XM Electronic Overspeed Detection System Figure 2.11 Relay Connection - Failsafe, Nonalarm Condition Figure 2.12 Relay Connection - Failsafe, Alarm Condition Alternate Relay Wiring Figures 2.13 and 2.14 show how to wire both ends of a single external indicator to the XM terminal base for either failsafe, nonalarm condition or failsafe, alarm condition. Figure 2.
Installing the XM Electronic Overspeed Detection System 35 Figure 2.14 Relay Connection - Failsafe, Alarm Condition Wiring the XM-220 Relays The on-board relay in each of the XM-220 modules will serve as the circuit fault relay for the overspeed channel (channel 1 of XM-220). The alarms associated with the XM-220 relay and whether the XM-220 relay is normally de-energized (non-failsafe) or normally energized (failsafe) depends on the configuration of the XM-220 module.
Installing the XM Electronic Overspeed Detection System Connecting the Remote Relay Reset Signal The XM-442 relays are latching relays. This means the relays stay activated even when the condition that caused the alarm has ended. The remote relay reset signal enables you to reset the XM EODS relays remotely after you have corrected the alarm condition. Wire the Remote Relay Reset Signal to the XM-442 terminal base unit as shown in Figure 2.15. Figure 2.
Installing the XM Electronic Overspeed Detection System 37 Connecting the Transducers The XM-220 modules can accept input signals from either a proximity probe transducer or magnetic pickup. The three individual transducers are connected to Channel 1 (terminals 0 and 16) of each of the XM-220 modules. For wiring connections pertaining to Channel 2, refer to the XM-220 Dual Speed Module User Guide.
Installing the XM Electronic Overspeed Detection System Connecting a Magnetic Pickup Sensor The figure below shows the wiring of a passive magnetic pickup sensor to Channel 1 of the XM-220 module. 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.
Installing the XM Electronic Overspeed Detection System 39 Other XM-220 Connections The XM-220 module includes two 4-20mA outputs, a buffered output for each input channel, and a DeviceNet™ connection that allows it to communicate with a Programmable Logic Controller (PLC), Distributed Control System (DCS) or another XM module. It can be connected to a Startup switch as well. For more information about XM-220 module, refer to the XM-220 Dual Speed Module User Guide.
