Abstract (en)
[origin: EP2671836A1] In an elevator safety controlling apparatus, a plurality of landing door switches are divided into a plurality of systems. A safety controlling portion can recognize opening of landing doors independently for each of the systems of the landing door switches. The safety controlling portion detects movement of maintenance workers into a hoistway if the landing door switches of any of the systems indicate an open door state when the car gate switch indicates a closed door state, and if the landing door switches in two or more of the systems indicate an open door state when the car gate switch indicates an open door state.
