8.3 Exchanging the electronics module

If the electronics module is defective, it can be replaced by the user.

In Ex applications only one instrument and one electronics module with
respective Ex approval may be used.

If there is no electronics module available on site, one can be ordered
from the VEGA agency serving you.

The settings of the sensor must be downloaded into the new
electronics module. This can be done:

l

At the factory by VEGA

l

Or on site by the user

In both cases, the sensor serial number is needed. The serial numbers
are stated on the type label of the instrument, inside the housing or on
the delivery note.
