8.4 Exchanging the electronics module

In case of a defect, the electronics module can be exchanged by the
user against an identical type. If no electronics module is available on
side, the module can be ordered for the VEGA agency serving you.
Ordering and exchange are possible with or without sensor serial
number. The electronics module with serial number includes order-
specific data such as factory setting, seal material etc. These are not
included in the electronics module without serial number.
The serial number is stated on the type label of VEGABAR 66 or on the
delivery note.
