Sick C4000 Palletizer Advanced safety light curtain

The C4000 Palletizer Advanced safety light curtain meets the demands of Performance Level ‘e’ according to EN ISO 13849 and SIL3 in line with IEC 61508. The C4000 Palletizer Advanced provides the possibility of human-material differentiation without supplementary muting components, and tolerance of object detection in a variety of detection situations, such as differing pallet loads, and strapping bands or foil projecting into the monitored field.

Typical light curtains detect objects when they interrupt one or more light beams. The C4000 Palletizer Advanced also uses the positions and number of interrupted beams for pattern detection by means of its self-learning, dynamic blanking function. This allows detection and monitoring of shapes and sizes by means of the safety-oriented querying of individual light beams. With horizontal installation it is possible, for example, to detect the width and shape of a pallet. This permits reliable differentiation between a person and an anticipated pallet for processing.

In horizontal use, the C4000 Palletizer Advanced offers savings potentials in the implementation of material flow locks entering or leaving hazardous areas. The system requires no supplementary muting sensors, indicator lamps, fences or doors for muting the safety function.

With the help of the Multiscan process and reduced resolution algorithm, the safe light curtain is designed to keep the taught-in pallet pattern, even with defective pallets with projecting wood splinters or strapping bands, or foil hanging down. Such interfering factors no longer lead to uncontrolled responses by the safety equipment and unnecessary interruption of the automatic transport.
