SG2 EXTENDED
Instruction Manual

When devices with > 40 mm resolution are used, the height of the top beam has to be
≥
900 mm (H
2
)
from machine supporting base while the height of the bottom beam has to be
≤
300 mm (H
1
).
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 ESPE in seconds (see chapter 10 “Technical data”)
t
2
= Machine stopping time in seconds
H = Beam height from the ground; it should be less than 1000 mm
