A passenger conveyor system has a controller and a safety device monitoring a safety-relevant system function. The safety device is in a “configured” state monitoring the safety-relevant function according to specifications when a target configuration parameter is stored. A system operating method includes: the controller receiving a first configuration parameter and a second configuration parameter created independently of the first parameter; transmitting the first and second parameters to the safety device; wherein the parameters relate to the same target configuration parameter; comparing the first and second parameters in the safety device and, when the parameters match within a prespecified tolerance, storing the corresponding target configuration parameter in the safety device and transmitting the target configuration parameter and/or a “configured” signal from the safety device to the controller. The controller controls the functionalities of the passenger conveyor system according to whether it received the target configuration parameter and/or the “configured” signal.

The present disclosure discloses a method and an apparatus for determining a leveling fault of an elevator. The method includes: acquiring a leveling signal and a target floor signal of an elevator, and determining whether the elevator is at a target floor according to the target floor signal; when yes, calculating a normal change sequence of signals of a leveling sensor of the elevator from a starting floor to the target floor; acquiring a real-time change sequence of the signals of the leveling sensor from the starting floor to the target floor; comparing whether the normal change sequence is the same as the real-time change sequence; and when the normal change sequence is the same as the real-time change sequence, determining that the elevator is normally leveled, and when the normal change sequence is different from the real-time change sequence, determining that the elevator has a leveling fault.

A method for controlling an elevator installation uses a computer-controlled mobile device. The elevator installation includes an elevator shaft having a plurality of shaft thresholds each assigned to one floor, an elevator car having a car threshold and is moveable along the elevator shaft, and a control unit for moving the elevator car. The mobile device has an evaluation unit that communicates with the control unit.
