Installing the XM-220 Dual Speed Module 27
Figure 2.15 4-20mA Output Connections
Connecting 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-220.
Wire the Remote Relay Reset Signal to the terminal base unit as shown in
Figure 2.16.
ATTENTION
The 4-20mA outputs are functionally isolated from other
circuits. It is recommended that the outputs be grounded at
a single point. Connect the 4-20mA (-) to the XM terminal
base (Chassis terminal) or directly to the DIN rail, or
ground the signal at the other equipment in the 4-20mA
loop.
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 will have to be
independently reset when necessary.
TIP
You can discretely reset a relay using the serial or remote
configuration tool.
