5 Installation and mounting
This chapter describes the preparation and completion of the installation of the safety light
curtain C 4000. The installation and mounting requires two steps:
$ determining the necessary safety 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 (chapter 7.2)
$ checking the installation (chapter 7.3)
5.1 Determining the safety distance
The light curtain must be mounted with the correct safety distance
$ from the hazardous point
$ from reflective surfaces
No protection without correct safety distance!
The reliable protective effect of the light curtain depends on the system being mounted
with the correct safety distance from the hazardous point.
5.1.1 Safety distance from the hazardous point
A safety distance must be maintained between the 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 defined in EN 999 and EN 294 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. C 4000 consisting of host and guest
(response times, see chapter “Response time” on page 69)
$ 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 safety distance as specified by
ANSI B11.191990 E.4.2.3.3.5 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. C 4000 consisting of host and guest
(response times, see chapter “Response time” on page 69)
$ reach or approach speed
$ other parameters that are stipulated by the standard depending on the application
