Methods and tools for servicing an elevator system

Abstract

Apparatus and methods for servicing an elevator system having a plurality of elevator cars under the supervision of a supervisory system processor. The system processor makes assignments to the cars according to a predetermined strategy. The servicing tool is connectable to the elevator system such that the positions of the cars in the building, the assignments to the cars by the system processor, and the status of the elevator cars, are displayed on a panel position and motion indicator or display. The servicing tool also includes pushbuttons for entering car and hall calls, and a mode select switch. The mode select switch includes an operating mode in which the system processor is maintained operational, and the controls of the cars are maintained operational, except the cars are inhibited from moving. The servicing method includes inhibiting the cars from moving while predetermined calls are entered into the system. The assignments to the cars, the change in assignments, and the change in the status of the cars as each call is entered, are noted by viewing the display. The display image, after each call is entered, may be compared with the correct image or response of the system processor and cars, to quickly check the system processor and car controllers to determine if they are operating properly.
