Calculating the supplement C
b
If y
ou have sufficient free space in front of your machine, use value 1200 mm as
the supplement C.
b
If you want to keep the minimum distance as low as possible, use the following
formula to calculate C:
C = 1200 mm – (0.4 × H
D
)
where:

H
D
= hei
ght of the protective field above the floor in millimeters (mm).
✓
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).
4.3.6.3 Height of the scan plane
Overview
If y
ou 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 (see figure 28, page 38). 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 (see figure 29, page 39).
