Abstract

A group control for an elevator system in which a call firmly assigned to a car, but not serviceable at a stop at the respective floor due to an expected overload, can be serviced subsequently by the same car. For this purpose first and second circuits, assigned to the floors, are provided. A selector scanning the floor and car call memories activates at every position the assigned first and second circuits, where the first circuit causes the car to pass the respective floor if an overload would be generated at a stop. The second circuits assigned to the upward and downward directions are linked to each other in such a manner that, on establishment of an overload, the scanning by the selector of the floor and car call memories assigned in each case to the calls of opposite direction is prevented. After passage of the non-serviceable floor and reaching of the point of return of the direction of travel, the car travels without interruption back to the earlier disregarded floor, whereby the blocking of the scanning of the floor and car call memories of the calls in the opposite direction is cancelled.
