7 Maintenance and fault rectification
7.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
7.2 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
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.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.
The hotline is available to you 7 days a week round-the-clock. Since
we offer this service world-wide, the support is only available in the
English language. The service is free of charge, only the standard
telephone costs will be charged.
Error Cause Rectification

Wrong mode se-
lected
Set the correct mode on the mode
switch (A - overflow protection, B - dry
run protection). Wiring should be car-
ried out according to the quiescent
current principle.
Operating voltage
too low
Check operating voltage
Shortcircuit in the
probe, e.g. be-
cause of moisture
in the housing
Remove the electronics module.
Check the resistance between the
marked plug connections. See the fol-
lowing instructions.
Electronics de-
fective
Press the mode switch (A/B). If the in-
strument then changes the mode, the
instrument may be mechanically dam-
aged. Should the switching function in
the correct mode still be faulty, return
the probe for repair.
Push the mode switch. If the probe
then does not change the mode, the
electronics module may be defective.
Exchange the electronics module.
Remove the electronics module. Check the resistance between the
two plug connections.
There must no longer be a connection (high impedance). If there is
still a connection - exchange the instrument or return it for repair
