SIPART PS2 PA Manual
A5E00127926--05
The positioner is largely maintenance--free. The positioners are fitted
with filters in the pneumatic connections as protection against coarse
particles of dirt. This dirt will be deposited under pressure on to the filter
and the filters may clog and impair the function of the positioner. In this
case the filters can be cleaned as follows.
Positioner in metal housing and explosion--proof version
1. Switch off the pneumatic power supply and remove the pipes.
2. Remove the metal filters carefully from the holes and clean (e.g.
with compressed air).
3. Insert the filters.
4. Re--connect the pipes and supply pneumatic energy.
