<Calculation Example>
● Calculation Example 1: For use in Europe
(OFF response time: 14ms or less, minimum sensing object diameter: 14mm)
First, calculate with K = 2,000.
S = K × T + C
= K × (T
= 2,000 × (T
= 2,000 × T
= 2,000 × T
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
3) In case S > 500 (mm)
S = K' × (T
= 1,600 × (T
= 1,600 × T
= 1,600 × T
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
In case this device is installed in a system with a maximum halting time of 0.1 (sec.)
S = 2,000 × T
= 2,000 × 0.1 + 28
= 228
Since this value matches with Case 2) above, S is 228 (mm).
In case this device is installed in a system with a maximum halting time of 0.4 (sec.)
S = 2,000 × T
= 2,000 × 0.4 + 28
= 828
Since this value matches with Case 3) above,
S = 1,600 × T
= 1,600 × 0.4 + 22.4
= 662.4
Since this value matches with Case 5) above, S is 662.4 (mm).
