Door Opener with Siedle HD 611-01

Hello everyone,

We have moved into a new apartment and now I want to connect the door opener to the Siedle HD 611-01.
Unfortunately the configuration doesn’t work.

I connected everything as described (picture attached).

Unfortunately the door cannot be opened using the opener - so I can’t get through the door opener’s setup configuration.
Does anyone have any idea what could be wrong?

Thanks for your help,

Arni
