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 5)
·
Aligning sender and receiver (chapter 6.2)
·
Checking the installation (chapter 6.3)
4.1
Determining the safety distance
The light curtain must be mounted with proper safety distance
·
from the point of danger
·
from reflecting surfaces
WARNING
No protective function without adequate safety distance!
The safe protective effect of the light curtain depends on the system being mounted with
the correct safety distance from the point of danger.
4.1.1
Safety distance from the hazardous area
A safety distance must be maintained between the light curtain and the point of danger.
This safety distance ensures that the point of danger can only be reached after the danger-
ous state of the machine has been removed.
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 deter-
mined 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 45)
·
Reach or approach speed
·
Resolution of the light curtain and/or beam distance
The safety distance as specified by OSHA § 1910.217 and ANSI/RIA R 15.06
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 deter-
mined 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 45)
·
Reach or approach speed
