2. If the result S is ≤500mm, then use the determined value as the minimum
dis
tance.
3. If the result S is >500mm, then recalculate S with an approach speed of 1,600
mm/s as follows:
S=1,600mm/s×T+8× (d–14mm)
4. If the new value S is >500mm, then use the newly determined value as the
minimum distance.
5. If the new value S is ≤500mm, then use 500mm.

Depending on the application and distance, persons must be prevented from standing

Example calculation
Mac
hine stopping time = 290ms
Response time after interruption of the light path = 30ms
Resolution of the safety light curtain = 30mm
T = 290ms +30ms = 320ms = 0.32s
S = 2,000mm/s × 0.32s +8 × (30mm –14mm) = 768mm
S >500mm, therefore:
S = 1,600mm/s × 0.32s +8 × (30mm –14mm) = 640mm
4.3.2.2 Taking reach over into account
In accordance with ISO 13855, it must not be possible to defeat the ESPE. If access to
t
he hazardous area by reaching over a protective field cannot be prevented, the height
of the protective field and minimum distance of the ESPE must be determined. This is
done by comparing the calculated values based on the possible detection of limbs or
body parts with the values resulting from reaching over the protective field. The greater
value resulting from this comparison must be used.
