Short-Circuit: The output is logical 1 if the UMC has detected a short-circuit at the PTC
inputs.
Open Wire: The output is logical 1 if the UMC has detected a cable break at the PTC inputs.
Temperature High: The output is logical 1 if the PTC resistance is above the hot threshold.
Resistance: Value measured from the PTC input in ohms.
The following parameter defines the behaviour of the function block. For more information about the single
