Normal approach
S ≥ 2000 (t1+t2),
S
with S ≥ 100
if S ≥ 500, then use:
S ≥ 1600 (t1+t2),
with S ≥ 500
Parallel approach
S ≥ 1600 (t1+t2)+(1200 - 0.4H), with H ≤ 875
S
or
S ≥ 1600 (t1+t2)+850, with 875 ≤ H ≤ 1000
with H ≥ 15 (R-50) where R is the light curtain resolution
(with H ≥ 150 mm for the FF-SYA60 light curtain)
Angled approach
if α ≥ 30°, then use the normal approach formula,
S
with Hu ≥ 900 mm and Hl ≤ 300 mm for the FF-SYA60 light
curtain.
if α ≤ 30°, then use the parallel approach formula,
α
with Hu ≤ 1000 mm and Hl ≥ 15 (R-50) where R is the light
curtain resolution
(with Hl ≥ 150 mm for the FF-SYA60 light curtain)
With :
S minimum safety distance (in mm, 100 mm = 3.9 in.)
t1 light curtain response time (in sec.)
t2 machine stopping time (in sec.)
H height of the detection plane above the reference floor (in mm, 100 mm = 3.9 in.)
Hu height of the uppermost beam above the reference floor (in mm, 100 mm = 3.9
Hl in.)
height of the lowest beam above the reference floor (in mm, 100 mm = 3.9 in.)
For more information, refer to the pr EN 999 European standard or comply with the
requirements on safety distances given by the type C European standard if existing
for the considered machine.
