Multibeam Models.
These models are suitable for the protection of
the entire body and must not be used to protect
arms or legs.
The minimum safety distance
S
is calculated
according to the following formula:
S = 1600 (t
1
+ t
2
) + 850
Î
The reccomended height
H
from the base
(G) must be the following:

HORIZONTAL POSITION OF THE BARRIER
When the object’s direction of approach is parallel to
the floor of the protected area, the barrier must be
installed so that the distance between the outer limit
of the dangerous area and the most external optical
beam is greater than or equal to the minimum safety
distance
S
calculated as follows:
S = 1600(t
1
+ t
2
) + 1200 – 0.4H
where
H
is the height of the protected surface from
the base of the machine;
H = 15(D-50)
(D=resolution)
In this case, H must always be less than 1 meter.
