be determined by comparison of the calculated values in Detection Zone Orthogonal to Direction of
Approach. The greater value resulting from this comparison shall be applied.
S=(K × T) + Cro . . . Formula (4)
• S: Safety distance
• K: Approach speed to the detection zone
• T: Total response time of the machine and FSG-R
• Cro: Approach distance based on the distance which
personnel can move towards the hazardous zone of a
machine by reaching over the detection zone. The distance
is determined in the table below based on the height of the
hazardous zone, a, and the height of the upper edge of the
detection zone, b.
Note: Lower edge of the detection zone above 300 mm in
relation to the reference plane does not offer sufficient
protection against crawling below.
First, use K = 2,000 mm/s in formula (4) for the calculation. If the result of this calculation is less than
100 mm, use S = 100 mm.
If the result exceeds 500 mm, use K = 1,600 mm/s to recalculate it. If the result of the recalculation is
less than 500 mm, use S = 500 mm.
Note 1. Upper edge of the detection zone below 900 mm is not included since they do not offer
sufficient protection against circumventing or stepping over.
Note 2. When determining the values of this table, it shall not be interpolated. If the known values a, b
or Cro are between two values of this table, the greater safety distance shall be used.
