Figure 4.6: Beam states
Up to four adjacent beam areas can be suppressed.
The beams can be activated or suppressed via the respective fieldbus interface (see chapter 9
et seq.), via the
ational controls on the receiver.
The behavior of each blanking area can be adapted to the requirements of the application:
Logical value of a blanking area
No beams are blanked
Logical value 0 for blanked beams
Logical value 1 for blanked beams
Logical value is the same as the adjacent
beam with lower beam number
Logical value is the same as the adjacent
beam with higher beam number
For an example configuration, see chapter 11.4.
NOTICE
Teach after changing the blanking configuration!
 Perform a teach after changing the blanking configuration (see chapter 8.2).
Auto blanking during teaching
If there are obstacles present in the measurement field at the installation site and at least one blanking
area is activated, interrupted beams can be mapped to the blanking area(s) during teaching. Existing
settings for the blanking areas are then overwritten (see chapter 8.2).
If no beams are interrupted during teaching, no blanking areas are configured.

Meaning in the application
All beams of the device are included in the evaluation.
All beams of the blanking area are taken into account
as interrupted beams (logical value 0) in the evalua-
tion.
All beams of the blanking area are taken into account
as free beams (logical value 1) in the evaluation.
All beams of the blanking area behave in the evalua-
tion like the previous beam.
All beams of the blanking area behave in the evalua-
tion like the subsequent beam.
