8 Maintenance and fault rectification
8 .1 Maintenance
When used as directed in normal operation, VEGAFLEX 66 is
completely maintenance free.
8 .2 Rectify malfunctions
The operator of the system is responsible for taking suitable measures
to remove interferences.
VEGAFLEX 66 offers maximum reliability. Nevertheless, faults can
occur during operation. These may be caused by the following, e.g.:
l 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.
However, should these measures not be successful, call the VEGA
service hotline in urgent cases 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
