Abstract
A method for performing a correction run by an elevator system having an elevator car following a loss of an elevator car position information includes: detecting a terminal landing magnet in response to the loss of the elevator position information; moving the elevator car away from a predetermined terminal landing until the terminal landing magnet is not detected; running the elevator car toward the predetermined terminal landing in response to not detecting the terminal landing magnet in said moving step; detecting two magnets simultaneously in response to running the elevator car toward the predetermined landing terminal; stopping the elevator car in response to simultaneously detecting the two magnets; and resetting the elevator position information in response to said stopping step.
