7 Maintenance and fault rectification
7.1 Maintenance
If the device 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.
VEGASWING 63 offers maximum reliability. Nevertheless, faults can
occur during operation. These may be caused by the following, e.g.:
•
Sensor
•
Process
•
Voltage supply
•
Signal processing
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.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no.

The hotline is manned 7 days a week round-the-clock. Since we offer
this service worldwide, the support is only available in the English
language. The service is free, only standard call charges are incurred.

Press the mode switch on the signal conditioning in-
strument. If the instrument then changes the mode, the
vibrating element may be covered with buildup or me-
chanically damaged. Should the switching function in
the correct mode still be faulty, return the instrument
for repair.
Press the mode switch on the signal conditioning in-
strument. If the instrument then does not change the
mode, the electronics module is defective. Exchange
the electronics module.
Unfavourable installation
location
Mount the instrument at a location in the vessel where
no dead zones or air bubbles can form.
Buildup on the vibrating el-
ement
Check the vibrating element and the sensor for buildup
and remove the buildup if there is any.
Wrong mode selected
Set the correct mode on the signal conditioning instru-
ment (overflow protection, dry run protection). Wiring
should be carried out according to the idle current prin-
ciple.
