Assembling the position sensor
NOTE!
Improper assembly may damage the lip seal in the guide
element.
The lip seal is pre-mounted in the guide element and must be
"locked into position" in the undercut.

seal.
→ Slide switch spindle through guide element.
→ To secure the switch spindle, apply a little screw locking paint
(Loctite 290) to the thread of the switch spindle.
→ Screw guide element into the actuator cover. Ensure that the
O-ring is positioned in the actuator cover.
→ Tighten guide element to 5 Nm.
→ Tighten switch spindle using a flat-tip screwdriver, maximum
torque 1 Nm.
2. Install sealing rings
→ Pull the form seal onto the actuator cover (smaller diameter
points upwards).
→ Check that the O-rings are correctly positioned in the pilot air
ports.
When the remote sensor is being installed, the collets of
the pilot air ports must not be fitted to the actuator.
