Calculating the supplement C
R
O
►
If you have sufficient free space in front of your machine, use value 1,200mm as
the supplement C
RO
.
►
If you want to keep the minimum distance as low as possible, use the following
formula to calculate C
RO
:
C
R
O
= 1,200mm – (0.4 × H
D
)
where:

D
= hei
ght of the protective field above the floor in millimeters (mm).
✓
If the result is C
RO
≥850mm, then use the calculated value as supplement C
RO
.
✓
If the result is C
RO
<850mm, then use C
RO
= 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 29, 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 30, page 39).
