5. Maintenance
The positioner is maintenance free.
The pneumatic connection 9/Supply con-
tains a filter with a mesh size of 100
µ
m. If
necessary, the filter can be unscrewed and
cleaned.
If applicable, observe the maintenance in-
structions for upstream pressure reducing
stations for supply air.
6. Servicing explosion-proof ver-
sions
If a part of the positioner on which the ex-
plosion protection is based must be ser-
viced, the positioner must not be put back
into operation until an expert has inspected
the device according to explosion protec-
tion requirements, has issued a certificate
stating this or given the device a mark of
conformity.
Inspection by an expert is not required if the
manufacturer performs a routine check on
the device prior to putting it back into oper-
ation. The passing of the routine check must
be documented by attaching a mark of con-
formity to the device.
