Replacing the Electronics Module
Explosion hazard!
For detectors used in the Ex-area, the electronics module must be
replaced solely by the BERTHOLD TECHNOLOGIES service or by
persons authorized by BERTHOLD TECHNOLOGIES. If this is not
possible, you must replace the entire detector or return it to the
manufacturer for repair.
IMPORTANT
Removal and installation of parts of the SENSseries detector should
be carried out in a clean workshop environment.
The electronics module has to be dismantled if one of the following
parts has to be exchanged:
• Electronics module (see page 2-231 )
• Crystal-multiplier combination for CrystalSENS (see page 2-
234 )
The electronics in the CrystalSENS is dismantled together with the
crystal-multiplier assembly. In the SuperSENS the electronics is dis-
mantled together with the multiplier.
4.3.1 Dismantling the Electronics Module
IMPORTANT
Since all detector parameters are stored on the electronics module,
you have to enter all the parameters again after you have
exchanged the electronics. If you still have access to the detector
parameters before the exchange, write them down so you can then
enter them into the new electronics. Otherwise, you have to re-
configure and re-calibrate the detector again. Please see the appro-
priate volume for instructions.
To replace the electronics module, you have to dismantle the hous-
ing overtube from the connection head.
You may carry out the activities described below only if the detector
is not used in an Ex-area.

Write down all software parameters of the installed detector.

Disconnect the detector from the power and switch off the
detector and any connected peripherals.
