Section 9-2
9-2 Safety distance for safeguarding danger areas
!WARNING
Additional countermeasures may be necessary to prevent access to the dan-
gerous area from above, below, the sides or the rear of the machine.
The height of the protective field "H" above the reference plane and the reso-
lution "d" of the MS4800 system have the following relationship:
H
min
= 15 x (d -50) or d = (H
min
/ 15) + 50
H
min
= Height of the protective field above the reference plane,
maximum height = 1000 mm.
It is considered that if height is equal or less than 300 mm,
adults can not crawl under.
d = resolution of the MS4800 system
S = (K x T) + C
For K and T please refer to the previous chapter
C = (1200 mm - 0,4 x H) but not less than 850 mm
(arm length)
H = Height of protective field above the floor
S = (1600 mm x T) + (1200 - 0,4 x H)
H
S

approach
50 mm - maximum distance
