Collective error
message
In the case of a Collective error message, the relay opens if one of the
following malfunctions occurs:

The sensor, which is properly registered to the DIQ/S 181, does not
provide a valid main measured value

The sensor, which is properly registered to the DIQ/S 181, does not
provide a valid secondary measured value
In any case, the relay remains open for 10 seconds and only closes
when the malfunction is no longer present.
In the following cases, the relay does not open despite an invalid
measured value:

The sensor is being calibrated

The sensor is in the maintenance condition

The sensor is being cleaned with the aid of a valve module
(compressed air operated cleaning system).
