ᐅ Smart home Somfy J4 io – Z-louvers blocked at the control sensor.

Dear Forum,

I hope I’m in the right place and that you can help me.

I have installed 11 external blinds with Z-shaped slats on my house, each equipped with a "Somfy J4 protect" motor and connected. Unfortunately, I made a mistake during the programming of one blind in the kitchen. I forgot to turn off the fuse for this kitchen blind, and during the programming of another blind in the basement, the slats accidentally pressed against the limit switch. According to the instructions, this should especially be avoided with Z-shaped slats.

Since then, the Z-shaped slats are tightly pressed against the bottom of the motor. When performing a double power interruption and using the programming button, followed by pairing the remote control either by pressing the "Down and Up" buttons simultaneously or by pressing the programming button alone, I can still hear the motor’s rocking movement, but the blind no longer releases from the sensor. That means I can program or teach in the remote (confirmation by the rocking is audible but not visible), but I can no longer adjust the lower end position. When I manually touch the limit switch, it is pressed very firmly against the topmost Z-slats.

I have only found the option for a reset or double power interruption in the lower end position, and according to the manual, this should only be done at a minimum distance of 30cm (12 inches) or more away from the limit switch.

My questions:
Is there a double power interruption option at the upper end position?
Can I manually operate the sensor so that the blind moves downwards?
Do you have any ideas on how I can release the blind from the limit switch again?

Thank you very much for any tips and help.

Kind regards,
Konrad

Hello,

this is how it worked for me:
1. One person pulls the blades on the sensor firmly downward so that they no longer touch the sensor. The blades must not touch the sensor anymore! Pull down with force!
2. At the same time, another person performs a double power interruption.

Result:
The blades return to their initial position and are no longer pressed against the sensor.

I hope this explanation helps.
Best regards
