Abstract: A passenger transport system includes a bus system transferring data between a central control unit and a plurality of field devices. In a failure detection method, the field devices are configured in an unbranched chain configuration and the control unit transmits a test telegram to a first field device to start a monitoring cycle during which each field device receiving the test telegram forwards the test telegram to a next field device in the chain. During the monitoring cycle, the control unit monitors a communication between the field devices occurring via the bus system, in order to detect when a field device does not forward the test telegram. A data volume transmitted via the bus system during the failure detection method is significantly reduced in comparison to conventional failure tests such that failures can be recognized more quickly and/or simpler hardware and/or software can be used.

Abstract: A brake device for braking an elevator installation traveling body movable along a guide rail includes a holder mounting a brake element having a brake surface movable relative to the holder between a freewheel position and a braking position. In a deactivated configuration, a pretensioning element does not exert any force moving the brake element towards the braking position, and in an activated configuration exerts such force. In a retaining state, a release element retains the pretensioning element in the deactivated configuration, and when activated into a released state, the release element changes the pretensioning element into the activated configuration. In an unactuated state, a friction-generating element does not abut the guide rail and, in an actuated state generates friction by abutting the guide rail to exert a force on the brake element and force the brake element towards the freewheel position.
