What I saw for this error is this

Err 55

Fault description:
Stop at another landing floor

Fault cause:
• Check F5-25 door open/close signal NO/NC
• Check the cable of door open/close signal
• Check the door close signal always valid

Disposal way:
Subcode 101- Check the door open limit signal at the present floor.

I checked all the fault cause but it does not align

I don't know if the unit has lost the ability to dispatch on automatic mode and to note the hall buttons works perfectly.
