Hello,

We had to replace siemens at25 door kit for siemens at40 kit. Kit includes door motor, controller and power supply. We have installed new parts and made the learning run for the doors in the controller, but the elevator is not moving. Service tool shows DDO when it is connected in LCB_2 (attachment). I've never done this door controller replacement with siemens parts so this is little bit new for me.

Can you guys help me with this? Elevator is Otis MCS 220
