Detection Zone Parallel to Direction of Approach
Use K = 1,600 mm/s and C = (1200 - 0.4 x H) in
formula (1) for calculation. Note that C must not be
less than 850 mm.
S = 1,600 mm/s x (Tm + Ts) + 1200 - 0.4 x H
• S = Safety distance (mm)
• Tm = Machine's response time (s)
• Ts = Response time of the F3SG-SR/PG from
ON to OFF (s)
• H = Installation height (mm)
Note that H must satisfy:
1000
≥
H
≥
15 (d - 50 mm)
≥
0mm
Also, you must include a hazardous condition under which a person may go through under a detection
zone if H exceeds 300 mm (200 mm for other purpose than industrial use) into risk assessment.
[Calculation example]
When Tm = 0.05 s, Ts = 0.008 s, and d = 14 mm:
S = 1,600 mm/s x (0.05 s + 0.008 s) + 1200 - 0.4 x 500 mm
= 1092.8 mm
When a warning zone is configured as in the figure, you must calculate L, a distance from an end of
casing to a detection zone, using a formula below:
L = (Total number of F3SG-SR/PG beams - number of warning zone beams - 1) x P + 10
• P: Beam Gap (mm)
Refer to
1-6-1. List of Models and Response Times
for
total number of F3SG-SR/PG beams.
Refer to
1-5. Ratings and Specifications
for beam gap.
