6.1 Exchange of adjustment
modules
The modular construction of VEGABAR allows
retrofitting, interchange or removal of the
display module. Data previously saved (e.g.
adjustment values) are not stored in the ad-
justment module but in an EEPROM of the
electronics module and therefore
readjustment is not necessary. The
connection of the modules is made via a 4-
pole plug connection.
Exchange of the adjustment module
Removal of the adjustment module
• Separate VEGABAR from the power
supply

plug connection of the display module
