System Operation and Functions
 Number of allowable beams
Number of beams in the floating blanking zone, that are not monitored by the Floating Blanking
Monitoring function.
When the Floating Blanking Monitoring function is enabled and the number of blocked beams becomes
less than "the number of Floating beams - the number of allowable beam(s)", the F3SG-SR enters the
LOCKOUT state.
Setting Example: the F3SG-RA with 14-mm detection capability
When the number of floating beams is configured as 4 beams, the safety outputs are turned OFF if 5 or
more beams are blocked. (Fig. 1)
If the number of floating beams is configured as 4 beams, the safety outputs are not turned OFF if 4 or
less beams are blocked. (Fig. 2)
If the monitoring function is being enabled and the number of allowable beams is configured as 1
beam, lockout occurs when a blocking object is lost or 2 or less beams are blocked. (Fig. 3)
When a blocking object of the size that does not turn off the safety outputs blocks multiple locations,
the safety outputs are not turned OFF. (Fig. 4)
