EOS4 SAFETY LIGHT CURTAIN

English
Vertical positioning of the light curtain
Models with 14, 20mm resolution
 These models are suitable for fingers detection.
Models with 30, 40mm resolution
 These models are suitable for hand detection.
The minimum safety distance is calculated according
to the following formula:
S = 2000 (t
1
+ t
2
) + 8(D-14)
(D=resolution)
This formula is valid for distances between 100 and
500 mm. If, according to the calculation, exceeds
500 mm, the distance can be reduced down to a
minimum of 500 mm using the following formula:
S = 1600 (t
1
+ t
2
) + 8(D-14)
If, in view of the particular configuration of the
machine, the dangerous zone can be reached from
above, the highest beam of the light curtain must be at
a height (from resting surface ) whose value is
determined by using the ISO 13855 Standard.

Vertical positioning
14mm, 20mm, 30mm, 40mm
Models with 50, 90mm resolution
 These models are suitable for detecting the arm
or the leg and must not be used to detect
fingers or hands.
The minimum safety distance is determined
according to the following formula:
S = 1600 (t
1
+ t
2
) + 850

In every case the height of the highest beam
from resting surface must not be smaller
than 900 mm, while the height of the lowest
beam must not be bigger than 300 mm (ISO
13855 Standard).
