How to replace a Bubendorff roller shutter motor with a Somfy

1. Access to the first apron attachment or automatic lock (also serving as a limit switch)

2. Access to the second apron attachment or automatic lock (also serving as a limit switch)

3. Fastener unhooked, the pin is released

4. Same for the other fasteners

5. Unclipping the axle support on the side opposite the engine (tandem side)

6. Following the unclipping of the axle support on the side opposite the engine (tandem side)

7. Removal of the axle support, non-engine side (tandem side)

8. Unclipping the axle support, motor side

9. Following unclipping of the axle support, engine side

10. Removal of the side panel clipped onto the slide (motor side)

11. Unclip the centering tab to release the side panel (motor side)

12.

13. Cheek removal

14. Removal of the power cable from the old Bubendorff motor. It is advisable to carefully disassemble the white clip at the bottom left to reuse it

15. Panel ready for adaptation of the new Somfy roller shutter motor

16. Bubendorff motor to be removed from the axle

17. To free the axle, remove it or the rivets, using an HSS Ø5 bit

18. Once the rivet(s) are removed, you can take out the Bubendorff engine

19. For this step, the materials needed are:

• SOMFY IO motor , with the motor torque adapted to your roller shutters.
• If necessary, LT50 wheel and crown for SOMFY motor adaptation on octagonal shaft Ø 60 mm from Bubendorff.
  It is provided when you buy a new engine

20. Materials also needed:

• Tradi Titan ID2 radio axis support , to install a SOMFY motor on a Bubendorff flange

21. The same support, seen from the side (available on https://lacentrale-eco.com/fr/ accessoires/axe-fr/support-daxe/support-daxe-tradi-titan-id2-radio-somfy-la- pair-bubendorff.html )

22. The same axis support

23. Prepare the SOMFY motor by positioning the cable on the side, in the notch provided.

Then cut the piece of yellow plastic to the right of the cable

24. Here is the cable when it is pre-positioned, with the plastic cut correctly

25. Position the outer holes of the ace support opposite the 2 corresponding reservations of the engine

26. Assembly of the engine on the ace support using 2 sheet metal screws 4.8x12, pan head PZ2.

Note that it may be necessary to shorten the length of the screw

27. Passage of the cable in the recesses provided for this purpose at the rear of the axle support

28. Motor and axis support ready to be assembled on the existing axis

29. Motor and axis support ready to be assembled on the existing axis

30. Motor and axis support ready to be assembled on the existing axis

31.Motor and axis support ready to be assembled on the existing axis

32. In this photo, you can clearly see the axis adaptation crown. It was slipped into the body of the Somfy motor

33. Assembling the SOMFY motor the SOMFY radio block N/R drawer. Find the drawer on Lacentrale-eco

34. Assembly of the SOMFY motor on the SOMFY radio N/R block drawer

35. Assembly of the SOMFY motor on the SOMFY radio N/R block drawer

36. To determine where to drill to assemble the new motor and the existing shaft, placethe engine exactly as in the photo

38.

39. Here is the place to drill, according to the SOMFY instructions

40. Note: when the flaps are not very wide, be careful not to slip the motor in the axis as in the photo.

The adaptation wheel, thus positioned, will prevent the refitting of the apron fasteners (or automatic locks)

41. The adaptation wheels are designed to have different positions in the axis, to position it correctly.

42. Correct positioning of the wheel and the motor, test that it is possible to reposition the fastener of part 1) to be certain that everything is ok

43. Drilling the axle and the wheel with an HSS Ø5 or Ø4.8 drill bit

44. Installation of 1 or 2 rivets 4.8x12 (one in front of the other, on either side of the axis)

45. Laughveteran

46. Properly set rivets

47. New SOMFY motor block/shaft support and Bubendorff roller shutter shaft assembled

48.

49. Positioning of the assembly in the cheek previously prepared in step 15

50.

51.

52. Correct clipping

53. Positioning of the new motor cable and white clips repositioned on the cheek

54. Rest the new assembly on the flap, pass the cheek well in my centering tab of the engine side slider

55.

56. Once the plastic lug is properly clipped into the metal tab, refitting is correct

57.

58. Refitting with clipping of the axle support in the cheek on the tandem side, side opposite the engine (remained in place)

59. Refitting the apron fasteners or automatic locks (also serving as a limit switch)

60. Electrical connection of the new motor

61. Return circuit breaker to service. Then make the adjustments necessary for the proper functioning of the new motor, according to the SOMFY instructions
