For a mapping of previously defined beam areas to, e.g., four switching outputs (Q1 to Q4), see
chapter 11.2.
NOTICE
Increased number of logical beams for the diagonal- or crossed-beam function!
 Take into account the (increased) number of beams if the "diagonal"- or "crossed-beam" mode is acti-
vated (see chapter 4.1.2 or see chapter 4.1.3).

4.10.4 Teach height area

With the "Teach height area" function, it is possible to teach in up to four height areas, e.g. for height moni-
toring or sorting packets. In many cases, this saves time for programming.
• A maximum of four height areas are available.
• A height area is automatically defined using an object.
When teaching a height area, all free beams above or below the object are combined into one height
area. Therefore, the object cannot be located in the center of the measurement field length; the first
or last beam must be interrupted.
