6 Alarm Outputs
Depending on the controller model, there can be up to two alarm outputs. Each alarm output can be configured for an alarm type
listed below. Alarm types are set in the initial setting mode. The alarm output is activated whenever the process temperature value
(PV) is getting higher or lower than the set point of alarm limit.
