Abstract (en)
[origin: WO2007090524A1] The invention relates to a safety switching apparatus (10) and to a method for safely turning on and off an electric consumer (22), in particular a system (16) operating in an automated manner. The apparatus (10) comprises a first port (32) for a first signalling element (18), a second port (34) for a second signalling element (20), and a first switching device (40) which is coupled to a first switching trip (36), and a second switching device (42) which is coupled to a second switching trip (38). A time-monitoring device (60) activates the first and second switching trips (36, 38) only when there is less than a predetermined maximum time duration (T<SUB>max</SUB>) between an actuation of the signalling elements (18, 20). The activation of the switching trips (36, 38) in turn causes the switching devices (40, 42) to be switched on, and hence the consumer (22) to be turned on. The activation of the switching trips (36, 38) requires the switching-on of first and second switching elements (48, 52) which are each arranged in series with the switching trips (36, 38). In one aspect of the invention, the time monitoring involves providing at least a first microcontroller (56) which is designed to detect actuations of the signalling elements (18, 20) and to switch on the switching elements (48, 52) if there is less than the maximum time duration (T<SUB>max</SUB>).
