When connected to a digital card, if desired, one of two alarms (or both simultaneously) can be
activated through Modbus registers. There are four possible actions for the alarms:
“None” will not use any of the alarm features (i.e. no alarms are used).
“AL1” will activate the first set of Modbus registers associated with Alarm 1.
“AL2” will activate the second set of Modbus registers associated with Alarm 2.
“Both” will activate both sets of Modbus registers associated with the alarms.
Additionally, a red indicator light illuminates on the front of the enclosure when any alarm
condition is met. Contact SSi for additional information on the alarm feature for this product.
