Maintenance and Repair
The replacing of fuses and the cleaning of the EVU are described in the mainte-
nance chapter.
IMPORTANT
The applicable national regulations of the respective country of use have
to be observed!
Repair and servicing on the EVU may only be carried out by experts (see chapter
2.3). In case of doubt, the complete EVU is to be sent to Berthold.
NOTICE
Repair on electronic circuits on the circuit boards of a field device may only
be carried out in the manufacturer's factory.
When working at electronic components, the relevant safety regulations must
always be observed. Particularly observe the safety instructions in the chapter “2
Safety”.
De-energize the detector and potentially connected relay contacts as well as
all inputs and outputs.
IMPORTANT
To achieve optimum measuring accuracy, we recommend recalibrating the
measuring system after a repair (not after changing the housing).
