Note: The value of K is:
2000 mm/s if the calculated value of S is
≤
500 mm
1600 mm/s if the calculated value of S is > 500 mm
When the dangerous area can be reached through the upper and
lower sides of the machine, where devices with >40 mm resolution are
used, the height of the uppermost beam shall be
≥
900 mm (H2) and
the height of the lowest beam shall be
≤
300 mm (H1).
If the safety light curtain must be mounted in a horizontal position
(Fig.7), the distance between the dangerous area and the most distant
optic beam must be equal to the value calculated using the following
formula:
S = 1600 mm/s (t
1
+ t
2
) + 1200 – 0.4 H
where
:
S
= Minimum safety distance in mm
t
1
= Response time of the ESPE in seconds (
see section 9
“Technical
data”
)
t
2
= Machine stopping time in seconds
H
=
Beam height from ground.
This height must always be less than 1000 mm.
