The safety distance for an access protection system may be calculated, based on EN 999
by means of the following formula:
S = K × T + C
Please also have regard, in this connection, to the diagrams given in this chapter.

reference boundary
Fig. 5.5-1:
Access protection by passage monitoring with system check of a
reference boundary
S = Safety distance, in mm
K = Approach velocity, in mm/s
Here = 1,600mm/s
T = Overall time of delay, in s,
a total consisting of:
Response time of the laser scanner
Here = 80ms
Overtravel time of the machine including the
controls
Based on measurement of
overtravel time
C = Added margin on account of the possibility
of manual intrusion
Here = 850mm
