Abstract
The device for controlling movement of a plurality of elevator cars in a single hoistway includes a door monitor module () that facilitates controlling movement of elevator cars (). The door monitor module () is configured to determine when at least one door () along a hoistway () is open. The door monitor module () places a first relay () in a selected operative state if a first elevator car () is stopped at a landing corresponding to the at least one open door. The door monitor module () places a second relay () in a selected operative state if a second elevator car () is stopped at a landing corresponding to the at least one open door. The door monitor module () is also configured to place both relays () into the selected operative state if neither of the elevator cars () is stopped at a landing corresponding to an open door () along a hoistway ().
