8-2
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 EN ISO 13855: 2010:
L =
the bottom opical beam must not have a height above the ref-
erence plane higher than 400 mm.
H =
the top optical beam must not be below 900 mm above the
reference plane.
The height of the protective field "H" above the reference plane and the reso-
lution "d" of the F3S-TGR-CL system have the following relationship:
S =
(K x T) + C
For K and T please refer to the previous chapter
C =
850 mm
S =
(1600 mm/s x T) + 850 mm
