Unlocking device, elevator system having an unlocking device, and method for actuating an unlocking device
An unlocking device with an actuator releases a safety cover of a maintenance opening for opening. The locking device has a safety circuit for actuating the actuator. The safety circuit includes at least one first switching contact and a second switching contact arranged in series, wherein the actuator in a closed state of the first and the second switching contacts is connected by the safety circuit with a power source, and the first switching contact can be switched by a control unit. One or more of the unlocking device can be used in an elevator system.
