Chapter 3 Alarm and Excitation Option

The alarm option enables the user to set a high and a low alarm
limit. When an alarm occurs, a red alarm LED indicator will turn
on and a normally open relay contact will close. The LED will turn
off and the relay will automatically reset when the alarm limit is no
longer exceeded. Two alarms are provided and are designated
LOW and HIGH on the front panel. Alarm limits are set by
potentiometers located behind the front panel lens.
