Example: 288 beams in parallel-beam scanning become 575 logical individual beams in diagonal-beam
scanning, which must be taken into account during evaluation functions. With a beam spacing of 5 mm,
this spacing is reduced to 2.5 mm in the center area.
The "diagonal" beam mode (diagonal-beam scanning) can be activated via the interface (see
chapter 9) or via the
NOTICE
Minimum distance for diagonal-beam scanning!
For diagonal-beam scanning, the minimum distance that must be maintained between transmitter and
receiver changes, whereby the values vary depending on beam spacing (see chapter 15).
NOTICE
Teach after changing the beam mode!
Changing the beam mode changes the number of beams used for the evaluation. Perform a teach
after changing the beam mode (see chapter 8.2).

Crossed-beam
The "crossed-beam" mode (crossed-beam scanning) is available for increasing the resolution for an area
of the measurement field. In "crossed-beam" mode, the light beam of each transmitter LED is detected in
succession both by the directly opposing receiver LED as well as by the two adjacent receiver LEDs (i+1,
i-1).
