Title: Elevator system

Abstract: A method of reinitializing an elevator system upon the return to service of an elevator car following the occurrence of an event which could result in the car stopping in the hatch without regard to floor level. The method includes the steps of determining if the elevator car is within a predetermined small distance from any floor, and if it is, the advanced car position is set to that floor. If the elevator car is not within this predetermined distance from a floor, the advanced car position is set to the closest floor in a predetermined travel direction, such as the travel direction of the car at the time of the event which terminated normal operation. The car is then moved to a predetermined floor, which is the floor of the advanced car position when there are no registered hall calls, and the floor of a predetermined car call, or hall call, where there is a registered call.
