3 Using this Manual This manual introduces you to the XM-361 and XM-362 Temperature modules. It is intended for anyone who installs, configures, or uses the XM-361 and XM-362 Temperature modules. Organization To help you navigate through this manual, it is organized in chapters based on these tasks and topics. Chapter 1 "Introduction" contains an overview of this manual and the XM-361 and XM-362 modules.
4 EXAMPLE Publication GMSI10-UM008D-EN-P - August 2010 This convention presents an example.
Chapter 2 Installing the XM-361/362 Temperature Modules This chapter discusses how to install and wire the XM-361 and XM-362 Temperature modules. It also describes the module indicators and the basic operations of the modules.
6 XM Installation Requirements This section describes requirements and considerations for an XM system. System Wiring Requirements Use solid or stranded wire. All wiring should meet the following specifications: • 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.
7 When using a 3-wire configuration, the XM-361 compensates for resistance error due to lead wire length. For example, in a 3-wire configuration, the XM-361 reads the resistance due to the length of the wires and assumes that the resistance of the other wire is equal. If the resistance of the individual lead wires is much different, an error may exist. The closer the resistance values are to each other, the greater the amount of error is eliminated.

9 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.

11 Figure 2.3 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 2.5. Use the grounding screw hole provided on the terminal base to connect the mounting plate the Chassis terminals. Figure 2.
12 Figure 2.5 Panel/Wall Mount Grounding 1 Power Supply 1 Power Supply 1 Publication GMSI10-UM008D-EN-P - August 2010 Use 14 AWG wire.
13 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. IMPORTANT IMPORTANT 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.
14 ATTENTION 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. 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).

24 Connecting a Remote Relay Reset Signal If you set the 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 the relay remotely after you have corrected the alarm condition. The Temperature modules do not have an on-board relay. The relays are added when an Expansion Relay (XM-441) module is connected to the Temperature modules.
25 Figure 2.11 Remote Relay Reset Signal Connection 1Ω, 1%, 1/4 or 1/2 W resistor ATTENTION The switch power supply is isolated, but shares common with Channel 4 and Channel 5 4-20 mA outputs. Care should be taken as to how these are grounded, if at all. A single switch contact can also be shared by multiple Temperature modules wired in series as shown in Figure 2.12.
26 Figure 2.12 Typical Multiple XM Modules Remote Relay Reset Signal Connection 1Ω resistor XM-361 Module Sensor Wiring The XM-361 accepts inputs from Thermocouples and 2-wire and 3-wire RTDs. Note that all six channels can be any mix of RTDs and thermocouple inputs. Connecting a Thermocouple Figure 2.13 shows the wiring of thermocouples to the terminal base unit of the XM-361 module.

38 XM-362 Module Sensor Wiring The XM-362 accepts inputs only from Thermocouples. All six input channels are electrically isolated from each other and from circuit power and ground. The isolation provided is up to 250 V. IMPORTANT With all the cable shields connected (six individual input cables and six output cables), there are not enough chassis terminals for each shield. Therefore, the cable shields should be paired as depicted in the following illustrations.
39 IMPORTANT IMPORTANT When using grounded and/or exposed thermocouples that are touching electrically conductive material, the ground potential between any two channels cannot exceed +250 Volts. Exceeding this voltage could cause permanent damage. Inside the XM-361 and XM-362 terminal bases are cold junction sensors used to determine the thermocouple measurements. These sensors have intelligent diagnostics that can determine cold junction out-of-range (OOR) conditions and hardware failures.
40 A special cable (Cat. No. 1440-SCDB9FXM2) is required for this serial 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. WARNING IMPORTANT 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.
41 IMPORTANT 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. ATTENTION ATTENTION ATTENTION IMPORTANT You must ground the DeviceNet shield at only one location.
42 Mounting the Module The XM-361 and XM-362 mount on the XM-944 terminal base unit, Cat. No. 1440-TB-E. You should mount the module after you have connected the wiring on the terminal base unit. ATTENTION The XM-361 and XM-362 are compatible only with the XM-944 terminal base unit. The keyswitch on the terminal base unit should be at position 5 for the modules. Do not attempt to install XM-361 and XM-362 modules on other terminal base units.
43 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. Position the module (D) with its alignment bar (E) aligned with the groove (F) on the terminal base. 5. Press firmly and evenly to seat the module in the terminal base unit.

46 Figure 2.35 Reset Switch Press the Reset Switch to reset the relays The switch can be used to reset all latched relays in the Expansion Relay module when it is connected to the XM-361 or XM-362. IMPORTANT Publication GMSI10-UM008D-EN-P - August 2010 The Reset switch resets the relays only if the input is no longer in alarm or the condition that caused the alarm is no longer present.
Chapter 3 Configuration Parameters This chapter provides a complete listing and description of the XM-361 and XM-362 parameters. The parameters can be viewed and edited using the XM Serial Configuration Utility software and a personal computer. If the module is installed on a DeviceNet network, configuring can also be performed using a network configuration tool such as RSNetWorx (Version 3.0 or later). Refer to your configuration tool documentation for instructions on configuring a device.
48 General Parameters Use the general parameters to configure the units of temperature that will be used by the XM-361 and XM-362 modules and to enable the relay reset switch terminals on theses modules. The general parameters in the EDS file also show the cold junction temperature and whether the cold junction temperature is over or underrange. General Parameters Parameter Name Description Values/Comments Temperature Units Sets the temperature units for the module.
49 Channel Parameters Parameter Name Description Values/Comments Channel Name (XM Serial Configuration Utility only) A descriptive name to help identify the channel in the XM Serial Configuration Utility Maximum 18 characters Sensor Type Sets the type of temperature sensor for the channel.
50 Channel Parameters Parameter Name Description Values/Comments Rate Time Constant The time constant used for smoothing (low-pass filtering) of the rate value. Seconds Note: The greater the rate time constant, the slower the response of the measured rate of change in the input signal (less sensitive to noise in the signal). Alarm Parameters The Alarm parameters control the operation of the alarms (alert and danger level) and provide alarm status. The XM-361 and XM-362 provide a total of 12 alarms.
51 Alarm Parameters Parameter Name Description Values/Comments Condition Controls when the alarm should trigger. Options: Greater Than Less Than Inside Range Outside Range • Greater than - Triggers the alarm when the measurement value is greater than or equal to the Alert and Danger Threshold values. The Danger Threshold value must be greater than or equal to the Alert Threshold value for the trigger to occur.
52 Alarm Parameters Parameter Name Description Values/Comments Alert Threshold (Low) The lesser threshold value for the alert (alarm) condition. Danger Threshold (Low) The lesser threshold value for the danger (shutdown) condition. Hysteresis The amount that the measured value must fall (below the threshold) before the alarm condition is cleared. For example, Alert Threshold = 120 and Hysteresis = 2.
53 Relay Parameters Parameter Name Description Options/Comments Number (XM Serial Configuration Utility only) Sets the relay to be configured in the XM Serial Configuration Utility. The relays are either relays on the Expansion Relay module when it is connected to the XM-361 or XM-362 or virtual relays. Virtual relays are non-physical relays. Use them when you want the effect of the relay (monitor alarms, delay, and change status) but do not need an actual contact closure.
54 Relay Parameters Parameter Name Description XM Configuration EDS File Utility Activation Logic Logic XM Configuration EDS File Utility Alarm A/B Alarm Identifier A/B Options/Comments Options: A only A or B A and B • A or B - Relay is activated when either Alarm A or Alarm B meets or exceeds the selected Alarm Status condition(s). • A and B - Relay is activated when both Alarm A and Alarm B meet or exceed the selected Alarm Status condition(s).
55 Relay Parameters Parameter Name Description Options/Comments Sets the alarm conditions that will cause the relay to Options: Normal Danger activate. You can select more than one. Sensor OOR Alert • Normal The current measurement is not within Alarm Levels Disarm excess of any alarm thresholds. Module Fault • Alert - The current measurement is in excess of the alert level threshold(s) but not in excess of the Check to enable. danger level threshold(s).
56 Relay Parameters Parameter Name Description XM Configuration EDS File Utility Failsafe Relay Failsafe Option 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.
57 4-20 mA Output Parameters The 4-20 mA output parameters define the characteristics of the 4-20 mA output signals. The XM-361 and XM-362 support a total of six 4-20 mA outputs. Each output is permanently associated with a corresponding channel. The parameters are the same for each output. IMPORTANT If the Enable Relay Reset Switch Terminals parameter is enabled, Channel 6 is not available for configuration, and the Channel 6 4-20 mA output is set to a fixed (12 mA) level.
58 IMPORTANT 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 above).
59 trend records, the interval between trend records, and which relay triggers (activates) the collection of the trend data. IMPORTANT The Triggered Trend parameters are not included in the EDS file and cannot be edited using generic configuration tools such as RSNetWorx for DeviceNet. Triggered Trend Parameters Parameter Name Description Values/Comments Enable Triggered Trend Measurements Enables/disables the triggered trend measurements. Select to configure the triggered trend measurements.
60 Triggered Trend Parameters Parameter Name Description Values/Comments Post Trigger The percentage of records to be collected once the trigger occurs. For example, if you set Post Trigger to 20%, then 80% of the records in the trend are before the trigger occurs, and 20% of the records in the trend are after the trigger occurs. 0 to 100 Percent This allows you to evaluate what happened after the trigger occurred. Status Shows the status of the trend data.
61 I/O Data Parameters The I/O data parameters are used to configure the content and size of the DeviceNet I/O Poll response message. IMPORTANT The XM-361 and XM-362 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 XM-361 or XM-362 will result in an error.
62 The Data parameters are used to view the measured values of the input channels and the 4–20 mA outputs, as well as to monitor the status of the channels, alarms, and relays. Data Parameters TIP To view all the data parameters in the XM Serial Configuration Utility, click the View Data tab. Channel Data Parameters Channel Data Parameters Parameter Name Description Values/Comments Channel Status States whether a fault exists on the associated channel.
63 Alarm and Relay Status Parameters Alarm and Relay Status Parameters Parameter Name Description Values/Comments Alarm Status States the current status of the measurement value and rate of change alarm. Possible status values: States the current status of the relay.
64 Device Mode Parameters The Device Mode parameters are used to control the functions and the behavior of the device. IMPORTANT The XM Serial Configuration Utility handles these parameters automatically and transparently to the user. Device Mode Parameters Parameter Name Description Values/Comments Device Mode Sets the current operation mode of the device. Refer to Changing Operation Modes on page 71 for more information.

78 XM Status Values The following tables describe the XM Status values that are included in the COS messages.
79 Figure B.1 Bit-Strobe Command The XM modules use the bit received in a Bit-Strobe connection as a trigger event. When the bit number corresponding to the XM module’s node address is set, the XM module will collect the triggered trend data. Note that the XM modules do not send data in the Bit-Strobe response. ADR for XM Modules Automatic Device Replacement (ADR) is a feature of an Allen-Bradley DeviceNet scanner.
80 • 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.
81 – All SU/CD Trend related parameters – Custom Assembly structure (see page 61) • 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.
