A: No.78 fault means when the elevator runs to the end station, the system does not detect the corresponding deceleration switch action

1. After shaft self-learning, the position of deceleration switch has been moved artificially, so it is suggested to conduct shaft self-learning again;
2. It's due to serious slipping of wire rope, suggest that the acceleration and deceleration parameters should be set a little lower to try the operation again, or the parameter P0.02 (maximum speed of the elevator) can also be set a little lower;
3. It can set F0.21 (leveling operation scheme) = 100, save parameters, and power on the all-in-one machine. Enable the scheme of end crawl leveling.
