The elevator should run in the direction of the call signal from the farthest floor. When the driver is operating, when the elevator has not started running, the driver should be given the possibility of forcibly changing the running direction of the elevator. In the maintenance state, only when the maintenance personnel directly and continuously press the direction button in the car or on the control box at the top of the car can the direction control of the elevator run, but when the direction button is released, the elevator will stop.

Floor display circuit: there must be a floor display in the passenger elevator car, and the floor display on the landing is determined by the elevator manufacturer according to the situation;

There used to be monitors on every floor of the elevator. With the improvement of elevator speed and group control dispatching system, many elevators cancel the floor display of landing or only keep the floor display of base station. When the elevator arrived at the call station, the acousto-optic forecast board was used. If the elevator is about to arrive at the station, the station bell rings, the direction light flashes or indicates the running direction of the elevator, and some people announce the station by voice in the carriage to remind passengers.
