System Operation and Functions
The muting is not enabled when the Temporalily Disable Monitoring by External Wiring is enabled.
 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-RA
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 output is 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 an interrupting object is lost or 2 or less beams are blocked. (Fig. 3)
When an interrupting object of the size that does not turn off the safety outputs interrupts multiple
locations, the safety outputs are not turned OFF. (Fig. 4)
5 or more beams are blocked
44-mm dia.
