8 Diagnosis, asset management and service
VEGABAR 87 • Modbus and Levelmaster protocol
46297-EN-220624
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.
+49 1805 858550
.
The hotline is also available outside normal working hours, seven
days a week around the clock.
Since we offer this service worldwide, the support is provided in
English. The service itself is free of charge, the only costs involved are
the normal call charges.
