Pilz safe radar system

The Pilz safe radar system comprises the LBK System safe radar system from Inxpect and the Pilz PNOZmulti 2 configurable small controller.

Up to six radar sensors are supported. In the event of a fault or when the protection zone is violated, PNOZmulti ensures that the reaction that is triggered is safe. The safe radar system solution can be used up to SIL 2, PL d, Category 2.

The safety-related functions covered by the system solution include the detection function, ie, when a machine is switched to a safe state as soon as a danger zone is violated, plus the restart interlock, which prevents the machine from starting automatically if there is anyone in the danger zone.

The layout of the protection zone can be flexible. The protection zone can be set up as wide or narrow, depending on the size of the area to be monitored. A wide protection zone covers a horizontal opening angle of 110° and a vertical opening angle of 30°. A narrow protection zone has an opening angle of 50° horizontal and 15° vertical. The actual protection zone of the sensor depends on the height at which the sensor is installed and the inclination (horizontal/vertical) of the sensor. A maximum depth of 4 m can be set.

The overall area of the application can be increased if six sensors are connected in series and arranged at a maximum distance of 2.5 m apart, allowing up to 15 m to be monitored.
