What occurs to the elevator doors in an automatic system when the car is called to a different floor?

In an automatic elevator system, when the car is called to a different floor, the doors on the elevator typically remain closed until the car arrives at the designated floor. Once the elevator reaches the requested level, the system activates the door mechanism to automatically open the doors. The purpose of this design is to enhance safety and efficiency, as it ensures that the doors do not open until it is appropriate to do so.

The automatic closing process occurs after the doors have opened for passengers to enter or exit the elevator. This automated mechanism is intended to streamline operations and improve the overall experience for users by eliminating the need for manual interaction with the doors during normal operation.
