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.
Error Cause Removal
VEGAMIP 61 signals
"covered" when the vibra-
ting element is not sub-
merged (overfill protection)
or
VEGAMIP 61 signals
"uncovered" when the vib-
rating element is submer-
ged (dry run protection)
Operating voltage too low Check operating voltage
Buildup on the sensor Check if there is buildup on the two sensors, and if so,
remove it.
Wrong mode selected 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.
Unfavourable installation
location
Mount the sensor (emitter/receiver) in a position where
there is a lot of measured product between emitting and
receiving unit.
Electronics defective Press the mode switch. If the instrument then does not
change the mode, the electronics module is defective.
Exchange the electronics module.
Sensor defective 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.
Signal lamp lights red Operating voltage too low Check operating voltage
Electronics module has
detected an internal failure
Exchange the instrument or send it in for repair

layed
