## Abstract

The invention relates to a safety system (1) for a separating protective device with a first monitoring device for monitoring whether the separating protective device is bolted with a bolting system and with a second monitoring device for registering the position of the separating protective device. The second monitoring device has a sensor that generates direction-dependent signals and that differs from the first monitoring device.

## Claims

### Claim 1

Safety system (1) for a separating protective device with a first monitoring device for monitoring whether the separating protective device is bolted via a bolt and with a second monitoring device for registering the position of the separating protective device, characterized in that the second monitoring device has a sensor differing from the first monitoring device that generates direction-dependent signals, in that the first monitoring device and the second monitoring device have diverse designs with respect to one another and do not reciprocally influence one another, in that the sensor is a 3-axis magnetometer (12), in that the 3-axis magnetometer (12) interacts with a magnet (13), and in that the 3-axis magnetometer (12) is arranged on an element that is fixed in place and that the magnet (13) is arranged on the separating protective device.

### Claim 2 (depends on 1)

Safety system according to claim 1, characterized in that movement directions can be registered in three spatial directions with the sensor.

### Claim 3 (depends on 1)

Safety system according to claim 1, characterized in that the sensor operates in a contact-free manner.

### Claim 4 (depends on 1)

Safety system according to claim 1, characterized in that the direction of movement of the separating protective device is registered via the sensor.

### Claim 5 (depends on 1)

Safety system according to claim 1, characterized in that the type of separating protective device is identified via the sensor.

### Claim 6 (depends on 1)

Safety system according to claim 1, characterized in that the movements of the door (4) registered by the sensor are input in a teach-in process.

### Claim 7 (depends on 1)

Safety system according to claim 1, characterized in that the separating protective device is adjusted or mounted in dependence upon signals generated with the sensor.

### Claim 8 (depends on 1)

Safety system according to claim 1, characterized in that the separating protective device is designed as a door (4).

### Claim 9 (depends on 8)

Safety system according to claim 8, characterized in that the door (4) is a sliding door or a swinging door.

### Claim 10 (depends on 1)

Safety system according to claim 1, characterized in that the first monitoring device is a transponder (10) for monitoring the bolting status of the bolt.

### Claim 11 (depends on 1)

Safety system according to claim 1, characterized in that it is a locking safety system, wherein the locking safety system has a locking unit monitored by a third monitoring device.

### Claim 12 (depends on 11)

Safety system according to claim 11, characterized in that the third monitoring device is a light barrier.
