7 Maintenance and fault rectification

7.1 Maintenance

When the device is used correctly, no maintenance is required in
normal operation.

7.2 Rectify malfunctions

The operator of the system is responsible for taking suitable measures
to remove interferences.
The first measure to be taken is to check the output signal. In many
cases, the causes can be determined this way and the faults rectified.
Cause
Operating voltage too low
Buildup on the sensor
Wrong mode selected
Unfavourable installation
location
Electronics defective
Sensor defective
Operating voltage too low
Electronics module has
detected an internal failure
Check switching delay
Removal
Check operating voltage
Check if there is buildup on the two sensors, and if so,
remove it.
Set the correct mode on the mode switch (max.:
overflow protection, min.: dry run protection). Wiring
should be carried out according to the quiescent current
principle.
Mount the sensor (emitter/receiver) in a position where
there is a lot of measured product between emitting and
receiving unit.
Press the mode switch. If the instrument then does not
change the mode, the electronics module is defective.
Exchange the electronics module.
Push the mode switch (min./max.). If the instrument
switches over, the sensor can be covered or mechani-
cally damaged.
Should the switching function on the correct mode be
wrong again, the you should return the instrument for
repair.
Check operating voltage
Exchange the instrument or send it in for repair
Adjust switching delay correctly
