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.:
•
Sensor
•
Process
•
Voltage supply
•
Signal processing
You can find information on fault rectification in the operating
instructions manual of the corresponding controller.
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.
7.3 Shortening the probe
The probe can be shortened by any amount.
Remove the insulation on a length of approx. 20 mm on the tip of the
probe. Hence the probe can detect the switching point in an optimum
way.
