8.4 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The first measures are:
•
Evaluation of fault messages, for example via the display and
adjustment module
•
Checking the output signal
•
Treatment of measurement errors
Further comprehensive diagnostics options are available with a PC
with PACTware and the suitable DTM. In many cases, the reasons 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 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.
