<Calculation example>
Calculation example 1 For use in Europe
(OFF response time: 11ms or less, minimum sensing object diameter: 30 (mm)
First, calculate with K = 2,000.
S = K × T + C
= K × (T
m
+ T
SF4
) + 8 × (d - 14)
= 2,000 × (T
m
+ 0.011) + 8 × (30 - 14)
=
2,000
×
T
m
+ 2,000 × 0.011 + 8 × 16
=
2,000
×
T
m
+ 150
If the result is:
1) In case S < 100 (mm)
Safety distance S is taken as 100 (mm)
2) In case 100
≤
S
≤
500 (mm)
Safety distance S is taken as 2,000 × T
m
+ 150 (mm)
3) In case S > 500 (mm)
S = K’ × (T
m
+ T
SF4
) + 8 × (d - 14)
= 1,600 × (T
m
+ 0.011) + 8 × (30 - 14)
= 1,600 × T
m
+ 1,600 × 0.011 + 8 × 16
≈
1,600 × T
m
+ 146
then, calculate again.
If the result is:
4) In case S
≤
500 (mm)
Safety distance S is taken as 500 (mm)
5) In case S > 500 (mm)
Safety distance S is taken as 1,600 × T
m
+ 146 (mm)
In case this device is installed in a system with a maximum halting time of 0.1 (s)
S = 2,000 × T
m
+ 150
= 2,000 × 0.1 + 150
=
350
Since this value matches with Case 2) above, S is 350 (mm).
In case this device is installed in a system with a maximum halting time of 0.3 (s)
S = 2,000 × T
m
+ 150
= 2,000 × 0.3 + 150
=
750
Since this value matches with Case 3) above,
S = 1,600 × T
m
+ 146
= 1,600 × 0.3 + 146
=
626
Since this value matches with Case 5) above, S is 626 (mm).
