EOS2 SAFETY LIGHT CURTAIN

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:
(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:
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.

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
according to the following formula:
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).
