Configurable functions
Beam coding increases the availability of the protected machine. Beam coding also en-
hances the resistance to optical interference such as weld sparks or similar.
In a cascaded system the host and guest always have the same beam coding. There is
no mutual interference.
Beam coding will increase the response time of the system. This will also change the
required minimum distance. Instructions can be found in chapter 5.1 “Determining the
minimum distance” on page 40.
After activating the system, sender and receiver will briefly display the coding.
Beam coding is only possible on systems with a maximum total of 405 beams.

4.7 Scanning range
Match the scanning range with the protective field width!
The scanning range of the system (host, guest 1 and guest 2) must be adapted to the the
protective field width. If the scanning range is too great, the safety light curtain may mal-
function. This would mean that the operator is at risk.
The available settings depend on the physical resolution of the system:

If the scanning range is set too low, the safety light curtain may not switch to green.
Tab. 7 shows the guaranteed scanning ranges for the system. You can also use the
C4000 in applications that require a larger scanning range if the orange LED is not
illuminated at the required scanning range.
If you are using the additional front screen (see page 110) available as an accessory,
the overall scanning range will be reduced by 8% for each additional front screen.
The deflector mirrors available as accessories (see page 110f.) reduce the overall
scanning range as a function of the number of deflector mirrors in the light path (see
Tab. 8). When using deflector mirrors, you must configure the safety light curtain for a
long scanning range.
Do not use deflector mirrors if the formation of droplets or heavy contamination of the
deflector mirrors is to be expected!
The formation of droplets of heavy contamination can be detrimental to the reflection
behaviour. The protective function of the system will be affected and the system will thus
become unsafe. This would mean that the operator is at risk.
