6. Mounting and Beam Alignment

6-1. Mutual Interference Prevention

When two or more F3SG-SR/PG systems are mounted in close proximity to each other, precautions should
be taken to avoid one system interfering with another, such as by beam alignment, back-to-back configura-
tion, physical barrier, Scan Code Selection, Operating Range Selection or adjusting the distances from adja-
cent safety light curtains.
In the Wired Synchronization, mutual interference is prevented in up to 3 sets, using interference light avoid-
ance algorithm.
In the Optical Synchronization, the scan code feature allows for placement of up to 2 sets of the F3SG-SR/
PG in close proximity and in line with each other. The distinctive coding of the beams provide for unique oper-
ation of a system while in view of another system with a different scan code. Two unique codes are available.
The emitter and receiver units must be set to the same scan code for the receiver to enter the MACHINE
RUN state. The scan code is selectable by the End Caps on the emitter and receiver units.
The F3SG-SR-K does not support the Scan Code Selection.
