5 Maintenance
No specific maintenance measures need to
be carried out.
To guarantee trouble-free operation of the
converter, make sure that the supply air is al-
ways clean (see section 9 on page 20 for
air quality).
Therefore, check the air filter and trap in-
stalled in the upstream air reducing station
regularly.

5.1 Cleaning the restriction

The restriction (see Fig. 11) is located inside
the enclosure. It can be accessed from the
back of the device. It can be taken out after
the screw plug (Ø10) has been removed.
When the output signal is too small or when
there is no output signal at all, the restriction
might be blocked. To remove blockages, take
the filter out of the restriction and clean or
replace it.

including filter
In addition, the pneumatic connections have
filters with plastic rims (order no. 0550-
0213) which can be removed for cleaning.

6 Servicing explosion-protected
devices
If a part of the device on which the explosion
protection is based needs to be serviced, the
device must not be put back into operation
until a qualified inspector has assessed it ac-
cording to explosion protection require-
ments, has issued an inspection certificate or
given the device a mark of conformity.
Inspection by a qualified inspector is not re-
quired if SAMSON performs a routine test
on the device before putting it back into op-
eration. Document the passing of the routine
test by attaching a mark of conformity to the
device.
Replace explosion-protected components on-
ly with original, routine-tested components
from the manufacturer.
Devices that have already been used outside
hazardous areas and are intended for future
use inside hazardous areas must comply
with the safety requirements placed on ser-
viced devices. Before being operated inside
hazardous areas, test the devices according
to the specifications for servicing explo-
sion-protected devices.
