Abstract
An apparatus (1) for controlling the operation of a machine (3) includes a device for monitoring the status of a safety device (2), in particular a safety switch for monitoring the closed status of a safety gate or similar of the safety device (2). When the safety device (2) is in the closed state, the apparatus (1) can provide an enabling signal for operation of the machine (3) and has a detection device (10) for detecting a locking insert (14). The insert can be effectively connected to the detection device (10), is portable, and can be removed from the detection device (10) without the use of a tool. When the safety device (2) is in the closed state, the apparatus (1) will provide the enabling signal only if the locking insert (14) is effectively connected to the detection device (10).
