Chapter 1 Install the XM-124 Standard Dynamic Measurement Module
Connect the Remote Relay Reset Signal
If you set the module 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 your module relay remotely after you have
corrected the alarm condition. This includes latched relays in the Expansion
Relay module when it is attached to the XM-124 module.
Wire the Remote Relay Reset Signal to the terminal base unit as shown in
Figure 29 .
Figure 29 - Remote Relay Reset Signal Connection
A single switch contact can also be shared by multiple XM modules wired in
parallel as shown in
Figure 30 .
TIP If you set a module relay to latching, make sure that any linked relays, such
as relays in an XM-440 Master Relay Module, are not configured as
latching. When both relays are set to latching, the relay in each module has
to be independently reset when necessary.
TIP You can discretely reset a relay using the serial or remote configuration tool.
ATTENTION: The Switch Input circuits are functionally isolated from
other circuits. We recommend that the Switch RTN signal be grounded
at a signal 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.
ATTENTION: The relay reset connections may be different for different
XM modules.
Figure 30 applies only to the XM-124 module. Refer to the
installation instructions for the module for its terminal assignments.
