Explanation of the safety distance in a vertical arrangement of the protective
field
Where K = 2000 mm/s and C = 0 mm, e.g., for SLCT14...
or C = 128 mm, e.g., for SLCT30...
the calculation formula for a distance S of 105 mm up to and including 500 mm is:
S = 2000 mm/s * (t
1
+ t
2
) + C
S = 1600 mm/s * (t
1
+ t
2
) + C
S must be at least 500 mm. Lower results must be corrected to a minimum
distance of 500 mm.
Example: vertical arrangement
t
1
= 50 ms
t
2
= 300 ms
Hand protection C = 128 mm
S = 2000 mm/s * (350 * 10
-3
s) + 128 mm
S = 700 mm + 128 mm =
828 mm
As S is > 500 mm, a smaller value can also be determined:
S = 1600 mm/s * (350 * 10
-3
s) + 128 mm = 688 mm
The minimum distance between protection field and danger zone must therefore
be
688 mm.

Note!
If S is greater than 500 mm, then K = 1600 mm/s must be used for calculations:
