7.1.1 Minimum distance to the hazardous area
A minimum distance must be maintained between the multiple light beam safety device
and the hazardous area. This ensures that the hazardous area can only be reached when
t
he dangerous state of the machine is completely at an end.
The minimum distance as defined in EN ISO 13855 and EN ISO 13857 depends on:
stopping/run-down time of the machine or system
(The stopping/run-down time is shown in the machine documentation or must be
d
etermined by taking a measurement.)
response time of the protective device (response times see chapter 13.1 “Data sheet”
on page 113)
reach or approach speed
resolution of the multiple light beam safety device or beam separation
other parameters that are stipulated by the standard depending on the application
Under the authority of OSHA and ANSI the minimum distance as specified by
ANSI B11.19:2003G04, Annex D and Code of Federal Regulations, Volume 29,
Part 1910.217 … (h) (9) (v) depends on:
stopping/run-down time of the machine or system
(The stopping/run-down time is shown in the machine documentation or must be
determined by taking a measurement.)
response time of the protective device (response times see chapter 13.1 “Data sheet”
on page 113)
reach or approach speed
other parameters that are stipulated by the standard depending on the application
