VERTICAL POSITION OF THE LIGHT CURTAIN
30 mm and 40 mm resolution models.
These models are suitable for the protection of
hands.
The minimum safety distance
S
is calculated
according to the following formula:
S = 2000(t
1
+ t
2
) + 8(D-14)
D=resolution (mm)
This formula is valid for distances
S
between 100
and 500 mm. If this formula results in
S
being
greater than 500 mm, the distance can be reduced
to a minimum of 500 mm by means of the following
formula:
S = 1600(t
1
+ t
2
) + 8(D-14)
If, due to the specific configuration of the machine,
the dangerous area can be accessed from above,
the highest beam of the light curtain must be at a
height
H
of at least 1800 mm from the base
G
of the
machine.

2, 3, 4 beams 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

The recommended height
H
from the base
(G) must be the following:
