Abstract: A car safety supervising unit (SSU) for an elevator having an elevator car displaceable within an elevator shaft includes at least one sensor for sensing car-related parameters and outputting corresponding car-related signals, an I/O interface for inputting input signals into the car SSU and for outputting output signals to external devices and a signal processing unit for processing at least one of the car-related signals and the input signals and for generating the output signals. In an installation operation mode, the signal processing unit processes exclusively the car-related signals and generates the output signals based exclusively on the car-related signals whereby the car SSU accomplishes basic safety functions for safely operating the elevator with a limited number of available sensors. In a normal operation mode, the signal processing unit processes both the car-related signals and the input signals and generates the output signals based on both.

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 safety circuit for an elevator system includes a first circuit having a plurality of switching contacts and a second circuit having a plurality of switching contacts. The switching contacts of the first circuit are connected in series, and the switching contacts of the second circuit are connected in parallel. Each switching contact of the first circuit is associated with a different switching contact of the second circuit. The switching contacts that are associated with each other are in opposite switching states.

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: An elevator safety supervising entity (SSE) includes a car safety supervising unit (SSU) controlling functions of car safety components and having at least one car sensor sensing car-related parameters, a head SSU controlling functions of shaft safety components and having at least one shaft sensor sensing shaft-related parameters, and a data linkage transmitting signal data between the SSUs. Both SSUs detect a failure in the other one of the SSUs and in the data linkage signal data transmission and in response switch from a normal operation mode to a failure operation mode. In the failure operation mode, the SSUs operate autonomously to keep the elevator operative at least temporarily with a sufficiently high safety even when functions of the elevator SSE are disturbed due to failures and e.g. passengers may be evacuated from the elevator car before completely stopping elevator operation.
