• When beams are blocked within the range from [1 beam next to bottom beam] to [1 beam next to top beam]
When beams are blocked within the range from [1 beam next to bottom beam] to [1 beam next to top beam],
allowable beams are configured as follows.
The table below lists the number of allowable beams when a fixed blanking zone and allowable beams
are configured with the SD Manager 3.
Number of allowable beams available for fixed blanking beams
Refer to 3-7-1. Setting Fixed Blanking by Teach-in for more information on Teach-in with the DIP Switch.
Refer to 4-3-4-1. Fixed Blanking for more information on setting a fixed blanking zone with the SD Manager 3.
For detection capability on the border between the blanking zone and normal detection zone when
allowable beam is configured, see next table.
