The signal converter electronics slide out easily once they have become detached from the
backplane PCB.

• To insert the new electronics, slide them back into the housing, retighten the two screws and

attach the display.

The measuring system recognises the hardware replacement when the power supply is
switched on. Following replacement of the sensor electronics (SE), or the entire sensor
including electronics or the signal converter electronics (BE), the device indicates a "fatal" error
status. In this case, the menu features various options depending on the status detected.

DANGER!
Work on the signal converter electronics may only be performed when disconnected from the
power supply.
