Excuse me, why are there so many control panels in the elevator? One on the top of the cabin, one on the wall of the machine room, and one on the cabinet inside the machine room
There are multiple control panels in the elevator to ensure its safety and proper operation. The control box located on top of the elevator car is typically used to control the operation of the car and the opening and closing of the doors ； The control box on the wall of the machine room is used to receive and process external signals, such as floor button signals and emergency call signals ； The cabinets in the machine room are responsible for the main control system of the elevator, including devices such as drives and controllers. These control boxes connect the various components through cables and wiring to ensure the safe and reliable operation of the elevator. .
