7 Diagnostics and servicing
7.1 Maintenance
If the device is used properly, no special maintenance is required in
normal operation.
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
7.2 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.:
•
Measured value from sensor not correct
•
Voltage supply
•
Interference in the cables
The first measure to be taken is to check the input and output signals.
The procedure is described as follows. In many cases the causes can
be determined this way and faults can be easily 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.
7.3 Diagnosis, fault messages
The controller and the connected sensors are permanently monitored
during operation. If irregularities occur, a fault signal is triggered. In
the event of a failure, the fault indication lights up and the relays are
de-energized (safe state).
