10 Diagnostics and servicing
10.1 Maintenance
If the device is used properly, no special maintenance is required in
normal operation.
In some applications, buildup on the antenna system can influence
the measuring result. Depending on the sensor and application, take
measures to avoid heavy soiling of the antenna system. If necessary,
clean the antenna system in certain intervals.
The cleaning helps that the type label and markings on the instrument
are visible.
Take note of the following:
•
Use only cleaning agents which do not corrode the housings, type
label and seals
•
Use only cleaning methods corresponding to the housing protec-
tion rating
10.2 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.:
•
Sensor
•
Process
•
Voltage supply
•
Signal processing
The first measures are:
•
Evaluation of fault messages
•
Checking the output signal
•
Treatment of measurement errors
A smartphone/tablet with the adjustment app or a PC/notebook with
the software PACTware and the suitable DTM offer you further com-
prehensive diagnostic possibilities. In many cases, the causes can be
determined in this way and the faults eliminated.
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.

.
The hotline is also available outside normal working hours, seven
days a week around the clock.
