The actuator is a Glideforce GF23-120504-3-65 High-Speed LD. I think I have to connect it throught the transformer but I am not sure. I would appreciate a wiring scheme, thank you.

Please note that the actuator requires a relatively high current (7 A). Since the relays of the LOGO! only have make contacts and no changeover contacts, you have to connect coupling relays afterwards.

The changeover contacts from this relays. K1 and not K2 is for backwards driving, K2 and not K1 is for forward driving.
