This value represents the time in seconds the alarm action will be delayed when an alarm limit has been exceeded. This value also
delays the alarm off action if an alarm limit is no longer exceeded. Default value = '0'.
Alarm Maximum Limit
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned int RW 0…32000 116 97/1 0x0C21/3106
Maximum limit for the ‘ 8 Measured Value’ to trigger the maximum alarm situation (after ‘ 182 Alarm Delay Time’). Range 0…32000
represents 0…100% signal. The ‘ 116 Alarm Maximum Limit’ value must be greater than the ‘ 117 Alarm Minimum Limit’ value. Default
value = '0'.
Alarm Minimum Limit
Type Access Range FlowDDE FLOW-BUS Modbus
Unsigned int RW 0…32000 117 97/2 0x0X22/3107
Minimum limit for the ‘ 8 Measured Value’ to trigger the minimum alarm situation (after ‘ 182 Alarm Delay Time’). Range 0…32000
represents 0…100% signal. The ‘ 117 Alarm Minimum Limit’ value must be smaller than the ‘ 118 Alarm Maximum Limit’ value. Default
value = '0'.
