Abstract (en)
[origin: ES8608439A1] An elevator control receives car calls for certain floors which are subject to a restriction of operation, but does not prevent the storage of these car calls. The car calls subject to the restriction of operation are only served during the trip in the opposite direction, if a load increase has been detected by a load measurement device during the change in the direction of travel. The restriction of operation is only cancelled during a predetermined time interval dependent on the movement of the car door and simultaneous occurrence of a load change caused by added travelers. Two storage cells are connected to the car call circuits for the car calls subject to the restriction of operation where an entered call, during a cancelled restriction of operation, is stored in the first storage cell and, during the restriction of operation, is stored in the second storage cell. A call stored in the first storage cell is transferred to the travel control of the elevator prior to the change of direction of travel and a call stored in the second storage cell is only transferred after the change of direction of the elevator.
