9 Maintenance and fault rectification
9.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
In some applications, product buildup on the separating diaphragms
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.
9.2 Fault rectification
The operator of the system is responsible for taking suitable measures
to remove interferences.
VEGADIF 65 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

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.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.
