value also delays the alarm off action if an alarm limit is no longer exceeded.
Default value = 0.
Alarm Maximum Limit
Type
Unsigned int
Maximum limit for Measure to activate the maximum alarm situation (after Alarm Delay Time). Range 0...32000 represents 0...
100% signal. Alarm Maximum Limit must be greater than Alarm Minimum Limit.
Default value: 0.
Alarm Minimum Limit
Type
Unsigned int
Minimum limit for Measure to activate the minimum alarm situation (after Alarm Delay Time). Range 0...32000 represents 0...
