    Abstract: An elevator system includes a control unit, a bus, a plurality of bus-nodes connected via the bus with the control unit, and a plurality of safety-state detection devices connected with the control unit via the bus-nodes. A method of commissioning the elevator system includes the steps: A) verification by the control unit of the safety-state detection means that are connected to the bus; B) checking of the functional capability of the safety-state detection means that are connected; C) checking by the control unit of the safety functions of the elevator system based on a change in state of a safety-state detection means; and D) release of the elevator system for a normal operation only after positive execution by the control unit of the steps A) to C), wherein the release is accompanied by a change in state of the control unit from an unsecured state into a secured state.

    Abstract: A method for operating a safety system including a control unit, a bus, a plurality of bus nodes connected to the control unit via the bus, and a plurality of participants connected to the control unit via the bus nodes, wherein at least one participant is designed as a temporary participant. The method includes the step of enabling the safety system for operation by the control unit when either a first temporary participant or a second temporary participant is connected to the bus. An elevator system can be provided with a safety system for carrying out the method.

    Abstract: A method for operating a safety system having a control unit, a bus, a plurality of bus nodes connected to the control unit via the bus, and a plurality of participants connected to the control unit via the bus nodes, wherein at least one participant is designated as a temporary participant. The method includes the step of logging the temporary participant out of the safety system by giving notice of a disconnection of the temporary participant from the safety system by a manipulation and disconnecting the temporary participant from the safety system. The safety system can be used with an elevator system for carrying out the method.

    Abstract: An elevator system drive unit moves an elevator car in an elevator shaft to at least two shaft access doors under control of a control unit. The car does not move or moves only to a limited extent if an individual is in the shaft. A monitoring unit and sensor (switching contact) detect changes in state in at least one of the doors using a sequence of pulses monitoring signal. The monitoring unit has a battery and can be switched to an autonomous mode when the elevator system is entirely or partially disabled. The monitoring unit, in the autonomous mode, records state data from the sensor and is connected to a safeguard unit that reads and evaluates the recorded state data, and prevents the elevator system from being put into the normal mode of operation if a change in the state of one of the monitored doors has been detected.

    Abstract: A method for operating a safety system having a control unit, a bus, a plurality of bus nodes connected to the control unit via the bus and a plurality of participants connected to the control unit via the bus nodes, wherein at least one participant is designed as a temporary participant. The method involves the steps that the temporary participant is notified in the safety system by the temporary participant being connected at a bus node to the safety system via the bus, the temporary participants is recognized by the control unit, the temporary participant is integrated into the safety system by the control unit and the temporary participant is activated at least once. A further aspect of the invention relates to a safety system for an elevator system for carrying out the method and to an elevator system having the safety system.
