Fixed Blanking Function
Summary
Disables specific F3SJ light beams.
When the fixed blanking function is used to disable detection in an
area, install blocking structures or shielding to prevent passage into
the entire hazardous area where detection has been disabled.
Failure to do so may prevent detection of people and result in serious
injury.
When an allowable range of light beams has been set for fixed
blanking, the size of the smallest detectable object will be larger in the
vicinity of interrupting objects. Calculate the safety distance to match
the settings.
After setting the fixed blanking function, you must verify that the F3SJ
detects a test rod at any position in the entire area where intrusion
must be detected. Failure to do so may prevent detection of people
and result in serious injury.
Example Application
In this example, there is always an object such as a conveyor belt in
the detection area, and we want to ignore the conveyor belt.
Description of Functions
Fixed Blanking Function
This function disables part of the F3SJ's detection area and maintains
the control output's ON status even if there is an object in the disabled
area.
The light beams set for fixed blanking must be one area of
consecutive light beams and up to five areas can be set (areas 1 to
5). Fixed blanking cannot be set for all of the light beams.
Setting the Fixed Blanking Area
Set the area that will be subject to fixed blanking.
An interrupting object can be placed in the detection area to perform
teaching and specify light beams for manual settings.
Note: 1. When the Setting Console is being used, only one area can

used, up to five areas can be set as fixed blanking areas.

Floating Blanking Function
Summary
Increases the diameter of the F3SJ's smallest detectable object and
turns OFF the control output when multiple objects are detected.
When the floating blanking function is used, it increases the diameter
of the F3SJ's smallest detectable object. Always use the larger
diameter when calculating the safety distance. If the incorrect
diameter is used in the calculation, the machinery may fail to stop
before an operator reaches the hazardous area, resulting in serious
injury.
After setting the floating blanking function, always verify that the F3SJ
system operates as expected. Serious injury may result if an
individual is not detected.
Example Application
When there is a moving object with a fixed width in the detection area
that we do not want to detect, the detection function can be disabled.
Description of Functions
Floating Blanking Function
This function increases the diameter of the smallest detectable object
to allow passage of objects of a certain size or allow interrupting
objects in multiple locations.
Setting the Floating Blanking Area
When the Setting Console is being used, all of the light beams are set
as the floating blanking area. When the SD Manager Setting Support
Software is being used, just one area can be set but the range of the
area can be specified. In the following example, the floating blanking
area is set from the 5th light beam to the 10th light beam (counting
from the bottom). An interrupting object can be placed in the detection
area to perform teaching and specify light beams for manual settings.
Floating Light Beams
The following charts show the relationship between the number of
floating light beams and the safety output operation (safety output not
going OFF). Measure the size of the interrupting object (maximum
diameter) and set the number of floating light beams so that the
object's size is less than the corresponding dimension shown in the
chart.
