7 Maintenance and fault rectification
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 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.
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.
Depending on the reason for the fault and the measures taken, the
steps described in chapter "
Set up
" may have to be carried out again.
