6.1 Exchange of adjustment
modules
The modular construction of VEGABAR allows
retrofitting, interchange or removal of the
adjustment and display modules. Data previ-
ously saved (e.g. adjustment values) are not
stored in the adjustment module but in an
EEPROM of the sensor electronics and there-
fore readjustment is not necessary. The con-
nection of the modules is made via a 4-pole
plug connection.

Removal of the adjustment module
• Separate VEGABAR from the power
suppy.

nection of the display module.

module.

justment module into the plug-in socket of

essary cable from the display module.
