By default the Fault relay is fixed as Energized and Non-latching and cannot be changed. The default
setting for the Alarm relay is De-energized and Non-latching. The current loop jumper pins at J6 are not
jumpered by default.
If 4–20 mA is not being used close the loop by placing the current loop jumper over pins (short J6). To
reset latched alarm, connect Reset (Terminal 1) to ground, recycle power or activate Reset magnetic
