Correction run for an elevator system

摘要

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: determining if a terminal landing magnet is detected in response to the loss of the elevator position information; if it is, 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 or in response to not detecting said terminal landing magnet in said determining 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.
