Configuration Parameters 59
Relay Parameters The Relay parameters control the operation of the on-board relay, as well as
the relays on the Expansion Relay (XM-441) module. Use these parameters to
configure which alarm(s) the relay is associated with, as well as the behavior of
the relay.
IMPORTANT
A relay can be defined, regardless of whether or not it is
physically present. A non-physical relay is a virtual relay.
When a relay (physical or virtual) activates, the module
sends a Change of State (COS) message to its master,
which acts on the condition as necessary. An XM-440
Master Relay Module can activate its own relays in response
to a relay (physical or virtual) activation at any of its slaves.
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. Relay Number 1 is the on-board relay.
Numbers 2 through 5 are either relays
on the Expansion Relay module when
it’s connected to the module 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. For example, a
PLC or controller monitoring the relay
status.
Note: The Relay Installed parameter
indicates whether a relay is a virtual
relay or a physical relay on a module.
Name (XM Serial Configuration
Utility only) A descriptive name to help identify the relay in the
XM Serial Configuration Utility. Maximum 18 characters
Enable Enable/disable the selected relay.
Note: The Relay Current Status is set to "Not
Activated" when the relay is disabled. See page 69.
