Pin 1/2: Provides an analog signal between 4 and 20 mA for the TOC measured value
between 0 and the limit (to be configured in the Settings menu, Options 1 tab).
Pin 3/4: Provides an analog signal between 4 and 20 mA for the Δ conductivity value
between 0 and the limit in μS/cm (to be configured in the Settings menu, Service 1 tab).
Pin 5/6: Acts as an NO contact if the configured TOC or conductivity limit value is
exceeded in the "analog output" option, or as an NC contact in the option with a group error
message in the event of a power failure, a reaction of the leak, lamp or pressure sensor
and if one of the two conductivity sensors is over range.
The measured value is updated every minute. During a calibration or the SST, the last value
is displayed until a new measurement is started.
