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

• Remove the screws on the upper side of

the housing and remove the cover or the

display module

• Disconnect connection cables from the

terminals, and if applicable, pull out the

plug connection of the display module

• Remove the two screws of the adjustment

module

• Remove adjustment module and pull out

plug connection

Insertion of an adjustment module

justment module into the plug-in socket of

the electronics module

• Fasten the new adjustment module

• Reconnect the connection cables, and if

applicable, also the cable from the

display module

of VEGABAR
