4.8 General course when calibrating, cleaning, servicing or
repairing an IQ sensor
When an IQ sensor is calibrated, cleaned, serviced or repaired, the mainte-
nance condition for the IQ sensor should always be switched on.
In the maintenance condition
 the system does not react to the current measured value or the condition of
the selected IQ sensor
 linked outputs are frozen
 IQ sensor errors do not prompt changes in the conditions of linked outputs.
The maintenance condition for IQ sensors is automatically activated
 during calibration. After calibration the IQ sensor remains in the maintenance
condition until the maintenance condition is switched off manually (see
section 4.8.3)
 during a compressed air cleaning cycle.
Therefore, keep to the following course when you calibrate, clean, service or
repair an IQ sensor.
