Maintenance
If the device is used properly, no special maintenance is required in
normal operation.

Rectify faults

The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The device offers maximum reliability. Nevertheless, faults can occur
during operation. These may be caused by the following, e.g.:
Measured value from sensor not correct
Voltage supply
Interference in the cables
The first measures to be taken are to check the input and output
signal as well as to evaluate the error messages via the display. The
procedure is described below. Further comprehensive diagnostics
can be carried out on a PC with PACTware and the suitable DTM. In
many cases, the causes can be determined in this way and faults
rectified.
Depending on the reason for the fault and the measures taken, the
steps described in chapter " Setup" must be carried out again or must
be checked for plausibility and completeness.
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.

Diagnosis, fault messages

When the connected sensor is provided with a self-monitoring
according to NE 107, the probably occurring status messages are
passed on and output on the VEGAMET indication. Requirement is
that the HART input of the VEGAMET is activated. You can find further
information in the operating instructions manual of the sensor.
