*) If because of the safety distance this value cannot be achieved, other measures e.g.mechanical
barriers must provide this distance.
S = Safety distance in mm
If the result is less than 100 mm, a distance of at least 100 mm must still be
maintained.
K = Approach speed in mm/s
In the close range of 500 mm, 2000 mm/s is used for the calculation. If the dis-
tance greater than 500 mm is calculated, K = 1600 mm/s may be used.
However, in this case a minimum safety distance of 500 mm is applied.
T = Total time of the delay in seconds;
Total of:
the response time of the protective device t

the response time of the safety interface, if any t

b)
and the machine‘s stopping time t

C = 8 x (d-14) in mm

a = Safety distance (S)
b = Measures to prevent penetration from above
c = Measures to prevent penetration from the sides
d = Measures to prevent penetration from the rear
e = Measures to prevent penetration from below
f = 75 mm – Maximum distance to avoid walking
