Mounting
6.3 Calculating the safety distance for a vertical
application
T
he safety light curtain must be mounted with sufficient safety distance:
from the hazardous point
from reflective surfaces
No protective function without sufficient safety distance!
The reliable protective effect of the safety light curtain depends on the system being
mounted with the correct safety distance from the hazardous point.
A safety distance must be maintained between the safety light curtain and the hazardous
point. This safety distance ensures that the hazardous point can only be reached after the
dangerous state of the machine has been completely stopped.
The safety distance as per 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
determined by taking a measurement.)
response time of the protective device (see section 12.2 “Response time” on page 99)
reach or approach speed
resolution of the safety light curtain and/or beam separation
other parameters that are stipulated by the standard depending on the application
Under the authority of OSHA and ANSI the safety distance as specified by
ANSI B11.19:2003L04, 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 entire protective device
(response times see chapter 12.2 “Response time” on page 99)
reach or approach speed
other parameters that are stipulated by the standard depending on the application
