8 Maintenance and fault rectification

8.1 Maintain

When the instrument is used properly, no special maintenance is
required in normal operation.
In some applications, product buildup on the diaphragm can influence
the measuring result. Depending on the sensor and application, take
precautions to ensure that heavy buildup, and especially a hardening
thereof, is avoided.
If necessary, clean the diaphragm. Make sure that the materials are
resistant to the cleaning process, see resistance list under "Services"
on "www.vega.com". The wide variety of applications of isolating
diaphragms makes special cleaning instructions necessary for each
application. Please ask the VEGA agency serving you.
Caution:
Never clean the separating diaphragm mechanical, for example with
tools when using instruments with isolating diaphragms! This can
damage the diaphragm and filling oil can penetrate.

8.2 Remove interferences

The operator of the system is responsible for taken suitable measures
to remove interferences.
VEGABAR 51 offers maximum reliability. Nevertheless, faults can
occur during operation. These may be caused by the following, e.g.:
Sensor
l
Process
l
Voltage supply
l
Signal processing
l
The first measures to be taken are to check the output signals as well
as to evaluate the error messages via the indicating and adjustment
module. The procedure is described below. Further comprehensive
diagnostics can be carried out on a PC with the software PACTware
and the suitable DTM. In many cases, the causes can be determined
this way and faults rectified.
However, should these measures not be successful, call the VEGA
service hotline in urgent cases under the phone no. +49 1805 858550.
