[Calculation example]
Tm = 0.29s, Ts = 0.02s, d= 14mm:
S= 2,000mm/s×(0.29s+0.02s) +8 × (14mm -14mm)
= 620mm . . . Formula (2)
If the result < 100mm, use S = 100mm.
If the result exceeds 500mm, use the following expression where K = 1,600mm/s.
S= 1,600mm/s × (Tm + Ts) + 8×(d -14mm) . . . Formula (3)
So S= 496mm
If the result of this formula (3) < 500mm, use S = 500mm.
(2) A system with larger detection capability than 40mm
Calculate by using Equation (1) with K = 1,600mm/s and C = 850mm:
S = 1,600mm/s × (Tm + Ts) + 850 . . . Formula (4)
• S = Safety distance(mm)
• Tm = Response time of the machine(s)
• Ts = KS06's response time from ON to OFF (s)
[Example]
Tm = 0.29s,Ts = 0.02s:
S = 1,600mm/s × (0.29s + 0.02s) + 850mm
= 1346mm
Calculate the safety distance according to American standard ANSI B11.19 (reference)
If a person approaches the detection zone of the F3SJ perpendicularly, calculate the safety distance as
shown below.
S = K × (Ts + Tc + Tr + Tbm) +Dpf
•S: Safety distance
•K: Approach speed to the detection zone(the value recommended by OSHA standard is 1,600mm/s)
Approach speed K is not specified in the ANSI B.11.19 standard. To determine the value of K to apply,
consider all factors, including the operator's physical ability.
•Ts = Machine's stopping time (s)
•Tr = Response time of KS06 from ON to OFF (s)
•Tc =Machine control circuit's maximum response time required to activate its brake (s)
•Tbm = Additional time (s)
If a machine has a brake monitor, "Tbm= Brake monitor setting time - (Ts + Tc)". If it has no brake
monitor, we recommend using 20% or more of (Ts + Tc) as additional time.
•Dpf = Additional distance
According to ANSI's formula, Dpf is calculated as shown below:
Dpf = 3.4 × (d - 7.0): Where d is the detection capability of KS06(unit: mm)
[Calculation example]]
K = 1,600mm/s, Ts + Tc = 0.07s, brake monitor setting time = 0.1s,
Tr = 0.02s, d = 14mm:
Tbm = 0.1 - 0.07 = 0.03s
Dpf = 3.4 × (14 - 7.0) = 23.8mm
S = 1,600 × (0.07 + 0.02 + 0.03) + 23.8 = 215.8mm
