If this value cannot be achieved because of the safety distance, other measures, e.g. mechanical
barriers, must guarantee the required maximum distance of 75 mm.
Warning!
If AOPDs with additional control functions are used, the resolution must be
≤
30 mm and the
minimum distance must be S
≥
150 mm.
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 area of 500 mm, 2,000 mm/s is used for the calculation. If the distance is great-
er than 500 mm, K = 1,600 mm/s can be used for the calculation. In this case, however, a
minimum of 500 mm applies for the safety distance.
