36 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.

ATTENTION
The Switch Input circuits are electrically isolated from
other circuits. It is recommended 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.
IMPORTANT
The on-board relay in each of the XM-220 modules must
be set to latching as well. To set the XM-220 relay to
latching, select the Latching parameter using either the
XM Serial Configuration Utility or a network configuration
tool such as RSNetWorx. Refer to Relay Parameters on
page 53.
