5 Installation and mounting
This chapter describes the preparation and completion of the installation of the safety light
curtain C4000. The installation and mounting requires two steps:
determining the necessary minimum distance
installation with swivel mount or side brackets
The following steps are necessary after mounting and installation:
making the electrical connections (chapter 6)
aligning sender and receiver unit (chapter 7.2)
checking the installation (chapter 7.3)
5.1 Determining the minimum distance
The safety light curtain must be mounted with the correct minimum distance
from the hazardous point
from reflective surfaces
No protection without correct minimum distance!
The reliable protective effect of the light curtain depends on the system being mounted
with the correct minimum distance from the hazardous point.
5.1.1 Minimum distance from the hazardous point
A minimum distance must be maintained between the safety light curtain and the
hazardous point. This minimum distance ensures that the hazardous point can only be
reached after the dangerous state of the machine has been completely stopped.
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
determined by taking a measurement.)
response time of the entire protective device, e.g. C4000 consisting of host and guest
(response times, see chapter “Response time” on page 79)
reach or approach speed
resolution of the 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 minimum distance as specified by
ANSI B11.19:2003@04, 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, e.g. C4000 consisting of host and guest
(response times, see chapter “Response time” on page 79)
reach or approach speed
other parameters that are stipulated by the standard depending on the application
