If the result is C ≥ 850 mm, then use the calculated value as supplement C.

If the result is C < 850 mm, then use C

850
mm (this value corresponds to an
arm's length and is valid as a minimum supplement to protect against reaching
over).

Height of the scan plane
Overview
If you choose a resolution of 70 mm for hazardous area protection, it is not possible to
detect a human leg under certain circumstances. This is because a beam does not hit
the leg. Rather, the beams pass by the sides of the ankle (
). If
you mount the safety laser scanner at a height of at least 300 mm (height of the scan
plane), the scan plane is at calf height and the leg is detected even at a resolution of
70 mm (
).
