NOTE: K value 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 devices with >40 mm resolution are used, the height of the top
beam has to be
≥ 900 mm (H2) from machine supporting base while
the height of the bottom beam has to be ≤ 300 mm (H1).
If the safety light curtain must be mounted in a horizontal position
(Fig.4), the distance between the dangerous area and the most
distant optical 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 AOPD 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
1,000 mm.
