4.9 Maintenance condition of sensors
The maintenance condition of sensors serves to calibrate, clean,
service and repair (remove and replace) sensors.
In the maintenance condition
 the system does not react to the current measured value or the
condition of the selected sensor

linked outputs are frozen
 sensor errors do not prompt changes in the conditions of linked
outputs.
The maintenance condition is automatically activated
 during calibration. After calibration the sensor remains in the
maintenance condition until the maintenance condition is switched
off manually (see section 4.9.2)
 during the cleaning cycle (see section 4.5.7)
Switch on the maintenance condition manually when you want to clean,
service or repair (remove and replace) a sensor (see section 4.9.1).
When you have finished cleaning, servicing or repairing the sensor,
switch off the maintenance condition manually (see section 4.9.2).
Note
When a sensor is in the maintenance condition, the measured values
or status indications of the sensor in the measured value display flash.
