Pilot air ports
(plug-in connectors with collets or
threaded bushings)
Position indicator
Figure 7: Installing the switch spindle (1), integrated pilot air duct
→Unscrew the transparent cap from the actuator.
→Unscrew position indicator from spindle extension.
→For variant with hose connector: remove the collets (white sleeves) from the pilot air ports.
Spindle extension
Guide element
Actuator cover
Lip seal
Puck
Switch spindle
Max. 5 Nm
Max. 1 Nm
O-ring
Figure 8: Installing the switch spindle (2), integrated pilot air duct
NOTE
Lipsealcanbedamagedifincorrectlyinstalled.
The lip seal is pre-mounted in the guide element and must be "locked into position" in the undercut.
▶When installing the switch spindle, do not damage the lip seal.
→Slide switch spindle through the guide element.
NOTE
Contaminationofthelipsealduetoscrewlockingpaint.
▶Do not apply any screw locking paint to the switch spindle.
→To secure the switch spindle, apply some screw locking paint (e.g. Loctite 290) in the threading of the
spindle extension in the actuator.
→Check that the O-ring is in the correct position.
→Screwguideelementinactuatorcover(tighteningtorque:max.5Nm).
→Screw switch spindle onto the spindle extension. A slot is provided on the top side (tightening torque:
max.1Nm).
→Push puck onto the switch spindle and lock into position.

2. Attaching the form seal
→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.
Before installing the device, remove the collets in the pilot air ports.

3. Installing the device
NOTE
DamageorfunctionaloutageofthePCB
▶Ensurethatthepuckliesatintheguiderail.
→Align the puck and device so that:
1. The puck rests in the guide rail of the device (see Fig. below).
2. Find the connection pieces of the device into the pilot air ports of the actuator (see second Fig.
below).

Figure 10: Aligning the puck
→Push the device without turning it onto the actuator until no gap is visible on the form seal.
NOTE
Damageormalfunctionduetoingressofdirtormoisture.
To observe the degree of protection IP65 or IP67:
▶Tighten fastening screws only with a tightening torque of max. 1.5 Nm.
→Attach device to the actuator using the two side fastening screws. In doing so, tighten the screws only
