What can be done by the setting tool
2. Non-Sequential Beam Mode
1. Sequential Beam Mode
If a size of an interrupting object is specified size or smaller, safety output is not turned OFF.
But if interrupting object(s) enter more than one zone of detection zone, safety output is turned OFF.
Under this mode, floating blanking monitoring can be configured. (It cannot be if number of floating
beams is 1)
For minimum detection capability, see “Detection Capability”.
For a size of an object which should not be detected, see “Floating Beam”.
- Floating Blanking Function p.70
- Detection Capability p.76
- Floating Beam p.71
Setting Example: F3SJ-A  N20 series
If number of floating beams is 3, minimum detection capability is 65mm.(Figure 1)
If number of floating beams is 3, and if diameter of an interrupting object is 40mm or smaller, safety
output is not turned OFF. (Figure 2)
If monitoring function is enabled and number of allowable beams is 2, the F3SJ locks out if an
interrupting object is removed or its diameter gets smaller than 20mm. (Figure 3)
Safety output can be turned OFF when more than one zone is interrupted by object(s) that should not
turn the safety output OFF. (Figure 4)
2. Non-Sequential Beam Mode
When total number of interrupted beams in an zone reaches the designated number or more, it is
evaluated as interruption.
