hello everyone!
He have an otis elevator with MCS 220M / 0VF 20 control panel.
Recently we have a problem, the elevator stops at (any) floor with open doors and n calls are accepted.
The errorwe get is door stall, but the door and the open-close contacts, are working properly
We must do a reset for the elevator to work corectly again, but once a day this error occurs.
Any toughts what may be the problem?
