| 摘要 |
The invention relates to a device (1) for releasably locking and signaling a specifiable state of a protective apparatus (2) of a machine (4) or the like, in particular a safety switch, the device (1) having an actuator receptacle (10) for accommodating an actuator (12), which actuator can be fastened to the protective apparatus (2), and the actuator receptacle (10) having a first signaling means (20), which is wirelessly operatively connected to a second signaling means (22) of the actuator (12) in the locked state of the apparatus (2), such that the locked state can be detected and signaled by the device (1), characterized in that the device (1) has a driving means (24), by means of which the actuator (12) can be moved in relation to the actuator receptacle (10) while the locked state of the protective device (2) is maintained, and that the device (1) determines whether a change, corresponding to the relative motion, of the signal representing the operative connection between the first signaling means (20) of the actuator receptacle (10) and the second signaling means (22) of the actuator (12) can be detected. |
