Safety Instructions
Observe the legal provisions that apply in your country!
Repair and maintenance work on the detectors must be performed
by competent personnel, see
Volume 1 , chapter 3 , "Qualification of
Personnel", page 1-19 . If in doubt, return the entire detector for
repair to BERTHOLD TECHNOLOGIES.
Also note the following points:
• Repairs to electronic circuits on the board of your SENSseries
detector must be carried out exclusively by the manufacturer.
• Any time you are working on electrical components, you have
to observe the relevant safety regulations. Please refer to the
safety instructions at the beginning of this User’s Manual. Turn
off the detector and disconnect any relay contacts and all inputs
and outputs.
Danger due to radiation!
Radiometric measurement devices use radioactive materials.
The source emits radiation through the source exit channel. There
may be a danger arising from radioactivity when people are
exposed to this radiation.
Always keep the source exit channel of the shielding closed during
assembly work.
Any work in the direct vicinity of the shieldings containing the radio-
active source may be performed only following proper training and
under professional guidance, see
Volume 1 , chapter 3 , "Qualifica-
tion of Personnel" . Repairs performed by untrained persons may
result in the loss of explosion protection.
Corrosion protection
If non-alloyed steel comes into contact with a stainless steel sur-
face, the surface can corrode at this point. Make sure, therefore,
that neither during installation nor during operation other metal
parts made of non-alloyed steel come into contact with the housing
surface of the detector.
ESD protective measures
The electronics of this measuring system contains electro-
static highly sensitive components. We recommend that
you wear an ESD wrist strap during installation or repair
work. Connect this wrist strap to the ground conductor.
