Configuration
Beam coding increases the availability of the protected machine. Beam coding also en-
hances the resistance to optical interference such as weld sparks.
Using different beam coding settings will allow one C4000 series sender/receiver pair
to be mounted in close proximity to another C4000 series sender/receiver pair without
optical interference.
Beam coding will increase the response time of the system. This will also change the
required safety distance. Instructions can be found in chapter 5.1 “Determining the
minimum safety distance” on page 29.
In order for the C4000 Select system to operate, both the sender and corresponding
receiver of each C4000 Select system must have the same beam code configuration.
After activating the system, the C4000 Select receiver will briefly display the coding.

Description
No beam coding
Beam code 1 active
Beam code 2 active
To prevent the possibility of optical interference from C4000 Select devices that have
been configured with the same beam codes (e.g. no coding, beam code 1 or beam code
2), a minimum distance between the two systems must be implemented. The following
figure provides information regarding the minimum distance “a” that must separate the
two C4000 Select systems based on the distance D between the sender of system 1 and
the receiver of system 2.
