Abstract (en)
[origin: WO2015090809A1] A safety circuit (1) for an elevator system preferably comprises a plurality of switch contacts (10.n, 11, 12.n), at least one first switch contact (10.n), and a control unit (30). The at least one first switch contact (10.n) can be switched electronically and can be bridged using a conductive bridging element (14.n), in particular for maintenance or testing purposes. Additionally, the control unit (30) is directly or indirectly connected to the safety circuit (1). The at least one first switch contact (10.n) can be switched on the basis of instructions of the control unit (30) in order to change the state of the safety circuit (1). In the process, the at least one control unit (30) is designed to detect the absence of the state change of the safety circuit (1), in particular when the at least one first switch contact (10.n) is being bridged by the bridging element (14.n).
