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 65 or on the
delivery note.
8 .5 Software update
The software version of VEGABAR 65 can be determined as follows:
l via the type label of the electronics
l via the indicating and adjustment module
l via PACTware
You can view all software histories on our website www.vega.com.
Make use of this advantage and get registered for update information
via e-mail.
The following components are required to update the sensor software:
l Sensor
l Power supply
l VEGACONNECT
l PC with PACTware
