APPARATUS FOR CONTROLLING THE OPERATION OF A MACHINE, LOCKING INSERT FOR SUCH AN APPARATUS, AND ASSOCIATED METHOD OF OPERATION
First Claim
1. An apparatus (1) for controlling the operation of a machine (3) having a device for monitoring the status of a safety device (2) for the machine (3), in particular a safety switch for monitoring the closed status of the safety gate or the like of the safety device (2), wherein, when the safety device (2) is in a closed state, the apparatus (1) can provide an enabling signal for the operation of the machine (3), characterized in that the apparatus (1) has a detection device (10) for detecting a locking insert (14), which locking insert can be operatively connected to the detection device (10), is portable, and can be removed from the detection device (10) without the use of tools, and that even when the safety device (2) is in a closed state, the apparatus (1) only provides the enabling signal when the locking insert (14) is operatively connected to the detection device (10).

Abstract
The invention relates to an apparatus (1) for controlling the operation of a machine (3), comprising a device for monitoring the status of a safety device (2) for the machine (3), in particular a safety switch for monitoring the closed status of a safety gate or similar of the safety device (2), wherein when the safety device (2) is in the closed state, the apparatus (1) can provide an enabling signal for operation of the machine (3), characterized in that the apparatus (1) has a detection device (10) for detecting a locking insert (14), which 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, and in that even 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). The invention further relates to a locking insert (14) for such an apparatus (1) and to an associated method of operation.
