2-8 Understanding Configurable FLEX Ex Thermocouple/RTD/mV Input Module Features
Underrange Alarm
The channel underrange alarm is set if the input is less than the
minimum temperature (thermocouple or RTD range dependent),
millivolt (-40mV) or resistance (0Ω) range value.
Range: 0 = normal, 1 = input overrange. Default = 0.
This alarm stays active at any value below 0% of range and is always
enabled by the module.
Range: 0 = normal, 1 = input overrange. Default = 0.
