EOS4 SAFETY LIGHT CURTAIN

English
Vertical positioning of the light curtain
Models with 30, 40mm resolution
 These models are suitable for hand detection.
The minimum safety distance S is calculated according
to the following formula:
S = 2000 (t
1
+ t
2
) + 8(D-14)
(D=resolution)
This formula is valid for distances S between 100 and
500 mm. If, according to the calculation, S 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 H (from resting surface G) whose value is
determined by using the ISO 13855 Standard.

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 S is determined
according to the following formula:
S = 1600 (t
1
+ t
2
) + 850
Î
In every case the height H of the highest beam
from resting surface G must not be smaller
than 900 mm, while the height of the lowest
beam P must not be bigger than 300 mm (ISO
13855 Standard).
