Maintenance mode Maintenance mode Maintenance mode Maintenance mode
The function of the maintenance mode is to set the device to maintenance mode in order to
enable easy cleaning of sensor, cable and meter. For this purpose a NO switch has to be
connected to CI 3 (Note the switch is not part of the scope of delivery. You have to buy this switch
with another manufacturer). In case CI 3 is activated the sampling cycle will be interrupted and
the sensor is moving back to the home position as soon as the external contact is closed. After
that, the current outputs are frozen and the sensor can be moved by the simple push of the
arrow buttons on the keypad.
