4.4.2 Maintenance condition
When an IQ sensor is calibrated, cleaned, serviced or repaired, the
maintenance condition for the relevant IQ sensor should always be
switched on.
In the maintenance condition
 apart from the measured value display, the system does not react to
the current measured value or the condition of the selected
IQ sensor
 IQ sensor errors do not prompt changes in the conditions of linked
outputs.
The following diagram gives you an overview of when an IQ sensor is
in the maintenance condition.
