Primary protective device
Vertical protective field
The primary protective device uses vertical light beams to continuously check whether
persons enter the hazardous area.
The area covered by the light beams is referred to as the protective field of the primary
protective device.
Horizontal protective field
During operation, the safety laser scanner uses its horizontal laser beams to continu‐
ously check whether people are present in a hazardous area.
The protective field of the safety laser scanner must be designed so that the entire haz‐
ardous area is reliably monitored. In conjunction with this safety system, the safety
laser scanner is referred to as a secondary protective device.
