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
If the safety light curtain must be mounted in a horizontal position
(Fig.6), 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.
