Relay Parameters
Use the Alarm, Relay and 4-20 mA Output tab in the XM-220 Speed Module
Configuration Tool to configure which alarms the relay is associated with, as
well as the behavior of the relay.
The on-board relay (Relay 1) serves as the circuit fault relay for the overspeed
channel (channel 1). It must be configured for failsafe operation (normally
energized) and latching.
To configure the relay parameters, follow these steps.
1. In the XM-220 Speed Module Configuration Tool, click the Alarm,
Relay and 4-20 mA tab. You will see a screen similar to this.
TIP
Press F1 to display the online help topic for the
current tab or dialog.
IMPORTANT
To ensure proper functioning of the XM EODS, Relay 1 in
each of the XM-220 modules must have the Failsafe relay,
Latching, and Module fault parameters enabled
(selected).
This checkbox must checked
in order to use the relay.
The activation logic must persist for this
length of time before the relay is activated.
The relay activation logic and what alarm
the relay is to monitor.
The alarm conditions that cause the relay
to activate. More than one can be
checked.
Check the checkbox if the relay is normally
energized. Uncheck the checkbox if the
relay is normally de-energized. This
checkbox must be checked for circuit fault
relay.
Check the checkbox if the relay is to be explicitly
reset (as required in the XM EODS). Uncheck the
checkbox if the relay is to reset itself. This
checkbox must be checked for circuit fault relay.
