Enabling and Disabling All Faults

When warning and alarm faults are enabled for a PRx module, the warning and alarm icons appear in the fault bar on the module faceplate.

CAUTION: If faults are disabled, the Alarm output and the PRx module LEDs will not give any indication of a warning or alarm condition if one occurs. On the OI, the warning and alarm icons will not appear in the controller faceplate fault bar and the bar will not change color if a warning or alarm occurs.

Touch the On/Off buttons to enable or disable Alarms and Warnings for the PRx module.

Setting Fault Output Failsafe Mode

The default failsafe mode for the PRx alarm output is ON. In this mode, the output is turned off when an alarm occurs. The optional mode is OFF, where the output will be turned on when an alarm occurs.

NOTE: In the default mode, the output will indicate an alarm if PRx module power is turned off or lost.

Touch the On/Off button to toggle the Failsafe mode on or off as desired.
