8 Maintenance and fault rectification

8.1 Maintenance

If the instrument is used properly, no special maintenance is required

in normal operation.

8.2 Rectify faults

The operator of the system is responsible for taking suitable meas-

ures to rectify faults.

VEGACAL 62 offers maximum reliability. Nevertheless, faults can oc-

cur during operation. These may be caused by the following, e.g.:

•

Sensor

•

Process

•

Voltage supply

•

Signal processing

The first measures to be taken are to check the output signals as well

as to evaluate the error messages via the display and adjustment

module. The procedure is described below. Further comprehensive

diagnostics can be carried out on a PC with the software PACTware

and the suitable DTM. In many cases, the causes can be determined

and the faults rectified this way.

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.

The following table describes possible errors and helps to remove

them:
