9-3 Safety distance and beam heights in access guarding
!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.
According to EN999 and EN294:
The height of the protective field "H" above the reference plane and the reso-
lution "d" of the MS4800 system have the following relationship:
S = (K x T) + C
For K and T please refer to the previous chapter
C = 8 x (d - 14)
d = resolution of the MS4800 system
S = (2000 mm x T) + 8 x (d - 14)
