Chapter 2 Installing the XM-441 Expansion Relay Module This chapter discusses how to install and wire the XM-441 Expansion Relay module. It also describes the module indicators and the basic operations of the module.
Installing the XM-441 Expansion Relay Module XM Installation Requirements This section describes wire, power and grounding requirements for an XM system. Wiring Requirements Use solid or stranded wire. All wiring should meet the following requirements: • 14 to 22 AWG copper conductors without pretreatment; 8 AWG required for grounding the DIN rail for electromagnetic interference (emi) purposes • Recommended strip length 8 millimeters (0.
Installing the XM-441 Expansion Relay Module IMPORTANT 13 Power connections are not made directly to the XM-441 module. Rather power is passed via the side connector from the Expansion Module's host module. Refer to that module's User Manual for further details on power requirements. 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.

Installing the XM-441 Expansion Relay Module 15 Figure 2.2 DIN Rail Grounding Block Panel/Wall Mount Grounding The XM modules can also be mounted to a conductive mounting plate that is grounded. See Figure 2.4. Use the grounding screw hole provided on the terminal base to connect the mounting plate the Chassis terminals. Figure 2.
Installing the XM-441 Expansion Relay Module Figure 2.4 Panel/Wall Mount Grounding 1 Power Supply 1 Power Supply 1 Mounting the Terminal Base Unit Use 14 AWG wire. The XM family includes several different terminal base units to serve all of the XM modules. The XM-943 terminal base, Cat. No. 1440-TB-D, is the only terminal base unit used with the XM-441.
Installing the XM-441 Expansion Relay Module 17 The terminal base can be DIN rail or wall/panel mounted. Refer to the specific method of mounting below. ATTENTION The XM modules make a chassis ground connection through the DIN rail. Use zinc plated, yellow chromated steel DIN rail 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.
Installing the XM-441 Expansion Relay Module 3. Slide the terminal base unit over tight against the neighboring terminal base. Make sure the hook on the terminal base slides under the edge of the adjacent base and the side connector is fully retracted. 4. Rotate the terminal base onto the DIN rail with the top of the rail hooked under the lip on the rear of the terminal base. 5. Press down on the terminal base unit to lock the terminal base on the DIN rail.
Installing the XM-441 Expansion Relay Module 19 1. Lay out the required points on the wall/panel as shown in the drilling dimension drawing below. Side Connector 2. Drill the necessary holes for the #6 self-tapping mounting screws. 3. Retract the side connector into the base unit. Make sure it is fully retracted. 4. Position the terminal base unit up tight against the neighboring terminal base. Make sure the hook on the terminal base slides under the edge of the terminal base unit. 5.

Installing the XM-441 Expansion Relay Module 23 There are four double pole double throw relays in the XM-441. All relay contacts (24 total) are available for wiring at the terminal base unit, as shown in Table 2.1 on the page 23. All XM relays are double pole. This means that each relay has two contacts in which each contact operates independently but identically.

Installing the XM-441 Expansion Relay Module 25 Figure 2.9 Relay Connection - Failsafe, Alarm Condition Non-failsafe, Alarm Condition Mounting the Module The XM-441 mounts on the XM-943 terminal base unit, Cat. No. 1440-TB-D. You should mount the module after you have connected the wiring on the terminal base unit. ATTENTION The XM-441 is compatible only with the XM-943 terminal base unit. The keyswitch on the terminal base unit should be at position 3 for the XM-441.
Installing the XM-441 Expansion Relay Module 1. Make certain the keyswitch (A) on the terminal base unit (C) is at position 3 as required for the XM-441. 2. Make certain the side connector (B) is pushed all the way to the left. You cannot install the module unless the connector is fully extended. 3. Make sure that the pins on the bottom of the module are straight so they will align properly with the connector in the terminal base unit. 4.

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 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 33 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. Each device on the network must have a unique node address between 0 and 63. Node address 63 is the default used by uncommissioned devices. Node address is sometimes called “MAC ID.” NVS (Non-Volatile Storage) NVS is the permanent memory of an XM module.
Glossary XM Serial Configuration Utility Software XM Serial Configuration Utility software is a tool for monitoring and configuring XM modules. It can be run on computers running Windows 2000 service pack 2, Windows NT service pack 6, or Windows XP operating systems.
