7.9.2 Behavior in non-operative condition
An output is non-operative when no function is activated for the output.
An output becomes non-operative in case of
 Power failure
(As soon as the supply voltage is sufficient again, the non-operative condition
of the outputs ends. The outputs function as specified by the user again.)
 Erasing a link to a sensor
 Changing the Measuring mode sensor setting for a linked sensor
 Changing the Measuring range sensor setting for a linked sensor

7.10 Maintenance condition of the sensors
The maintenance condition of the sensors is used for calibrating, cleaning, ser-
vicing and repairing (removing and exchanging) the 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 7.10.2)
 during the cleaning cycle (see section 7.6.7)
If you want to clean, service or repair (remove and exchange) a sensor, switch
on the maintenance condition manually (see section 7.10.1).
When you have finished cleaning, servicing or repairing the sensor, switch off
the maintenance condition manually (see section 7.10.2).
Before editing sensor settings a note appears on the display to
inform you that links will be erased when you change the
Measuring
mode or Measuring range sensor setting.
