Service and Maintenance

SIPART PS2 Zusatzbeschreibung
A5E00245544-03
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.
Position controller in plastic housing
Removal
1. Switch off the pneumatic power supply and remove the lines.
2. Unscrew the cover.
3. Remove the three screws of the pneumatic connecting strip.
4. Remove the sieves and O-rings behind the connecting strip.
5. Clean the sieves (e.g. with compressed air).
Installation
6. First insert the filters in the recesses in the plastic housing and then
place the O-rings on the filters.
7. Align the pneumatic connector strip on the two lugs and screw tight
with the three self-tapping screws.
Important:
Make sure that the same thread is used. To do this turn the screws
counterclockwise until they snap into the thread audibly. Only then
should you tighten the screws.
8. Replace the cover and screw it tight.
9. Re-connect the pipes and supply pneumatic energy.
