Parameter Description
Upper mA input signal range to detect whether detector is inhibited or
not.
Lower mA input signal range to detect whether detector is inhibited or
not.
Upper allowable limit for the input signal from the sensor/detector. If the
signal is out of this limit, the I/O board will generate an input signal fault.
Lower allowable limit for the input signal from the sensor/detector. If the
signal is out of this limit, the I/O board will generate an input signal fault.
Upper mA input signal range to detect remote warning from the detector
Lower mA input signal range to detect remote warning from the
detector.
Target span gas concentration. Normally it is 50 %FSD.
STEL period in minutes. The catalogue is using index instead.
TWA period in hours. The catalogue is using index instead.
Upper deadband range. The gas concentration within the deadband
limit will be suppressed to default base concentration. In other words if
the gas concentration is between (default base concentration - lower
deadband) and (default base concentration + upper deadband), then
the reading will be default base concentration.
Zero gas concentration. It is normally zero.
