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.
VEGAVIB 63 offers maximum reliability. Nevertheless, faults can oc-
cur 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. +49 1805 858550.
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.

Check operating voltage
Press the characteristic reversal switch. If the instru-
ment then changes the mode, the vibrating element
may be covered with buildup or mechanically damaged.
Should the switching function in the correct mode still
be faulty, return the instrument for repair.
Push the characteristic reversal switch. If the instrument
then does not change the mode, the electronics mod-
ule may be defective. Exchange the electronics module.
Mount the instrument at a location in the vessel where
no dead zones or air bubbles can form.
Check the vibrating element and the sensor for buildup
and remove the buildup if there is any.
Set the correct characteristics on the characteristics re-
versal switch (overflow protection, dry run protection).
Wiring should be carried out according to the idle cur-
rent principle.
