Problem Urmet 1133/15

I can’t get nuki to work on my Urmet 1133/15 intercom which I replaced with an old Urmet 1130 / 3D (bridge between 6 and 10). I tried to configure it several times but it doesn’t seem to give any impulse for opening the door.

How did you connect the Opener to the intercom system, please share a photo.
Best regards
