Hi I have a 3 stop hydro with an Otis 211 controller. Found the car shut down at the second landing with the PI flashing the proper floor. I saw the 2 dto fault and I think it means "door timer open" fault or something. No paperwork on job and no hand tool. I can get one but I don't have one handy. The car and hatch doors seem very nice mechanically and the door operation in service looks good too. Tape guides look good. Contacts in the door operator read good as well. Anything else that could trigger this fault?
