摘要:
An elevator system including an elevator car mounted for movement in a structure to serve the floors therein, and a car position indicator for displaying the position of the car in the structure. The car position indicator displays the car position according to a first mode during normal system operation, and, in response to the car becoming disabled, it switches to a second display mode which more accurately indicates the position of the elevator car relative to the floors of the structure.
