Of course all of the errors point to door control.
*Can you see on the door controller or on the main controller the door inputs for open limit and close limits?
*That last “fault cause” - that the close limit seems to be on/valid all the time, is it on regardless of door position?
*Are the DOL/DCL limits magnetic type?
*And you’ve checked each wire for the door control on the door controller and on the main controller to be sure they’re tight and secure?
