5.1. Installation of the electrical cable feed-through in the SRU rotary actuator
You require these instructions only if you would like to retrofit an EDF on an existing SRU unit.
SRU units can already be ordered equipped with EDF ex-works.
1. Feed the cable through the hole in the flat seal and position it in the recess in the distributor
plate.
2. Screw the thread reducer (item 7) into the pinion in the thread below the flat recess and
secure with Weicon 302-22. (Not for EDF for SRU20/25)
3. In order to position the distributor plate, place the two corresponding guide sleeves in the flat
recesses.
4. Pull the cable through the center bore of the SRU rotary actuator until the distributor plate is
just in front of the pinion.
5. Place the O-rings in the recesses of the air feed-throughs in the pinion.
6. Pull the cable through fully and position the distributor plate correctly on the pinion.
IMPORTANT
Damage to the cable connection of the adapter plate is possible
!
– Do not pull on the cable too strongly!
7. Now fasten the distributor plate on the pinion with the two screws (item 28).
8. Check the tightness of the air feed-throughs.
9. Turn the rotary actuator and place it on the distributor plate.
10. Swivel the SRU counter-clockwise up to the stop.
11. Knock the clamping pins into the bores on the pinion.
12. Pull the cable end through the bore in the flange.
13. Solder the cable onto the flange connector (item 22) in accordance with specifications
(see chapter 5.2).
14. Align the cable spiral and shape into original form. Spiral diameter approx. 27 mm.
15. Using a paint brush, grease the flange (inside) and the cable spiral with milk fat.
16. Place the cable in the clamping groove in the flange.
17. Fit the O-ring (item 47) at the connector flange.
18. Screw the connector onto the cover plate.
19. Screw the cover plate onto the flange with the oval head screws.
20. Fasten the flange on the SRU with two screws and secure with Weicon 302-22
21. Place the O-ring (item 43) in the MDF media feed-through flange.
22. Fasten the cover plate (item 6) on the flange with 2 countersunk screws.
Disassembly is carried out in reverse order.
