7 Maintenance and fault rectification
7.1 Maintenance
If the device is used properly, no special maintenance is required in
normal operation.
The cleaning helps that the type label and markings on the instrument
are visible.
Take note of the following:
•
Use only cleaning agents which do not corrode the housings, type
label and seals
•
Use only cleaning methods corresponding to the housing protec-
tion rating
7.2 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The first measure to take is to check the output signal. In many cases,
the causes can be determined this way and the faults quickly rectified.

Buildup on the sensor
Check if there is buildup on the two sensors, and if so,
remove it.
Note the instructions in chapter "
Mounting
" if there is
buildup in the socket.
Wrong mode selected
Set the correct mode on the mode switch (max.: over-
flow protection, min.: dry run protection). Wiring should
be carried out according to the idle current principle.
Unfavourable installation
location
Mount the sensor (emitter/receiver) at a location where
there is a large quantity of measured product between
the emitting and receiving units.
Mount the sensor (emitter/receiver) at a location where
there are no interfering installations or moving parts.
Electronics defective
Press the mode switch. If the instrument then does not
change the mode, the electronics module may be de-
fective. Exchange the electronics module.
Sensor defective
Operate the mode switch (min./max.). If the instrument
then switches mode, the sensor may be covered with
buildup or mechanically damaged.
If the switching function in the correct mode is faulty, re-
turn the instrument for repair.
