Installation
Prevention of Mutual Interference
For series connection
Refer to the “Precautions for Correct Use” for individual models for
information on preventing mutual interference of linkable Safety Light
Curtains.
For no series connection
When installing two or more pairs of light curtains independently from
each other due to inconvenience of wiring or other reason, take
proper measures to prevent mutual interference. If mutual
interference occurs, a lockout condition will result for the Safety Light
Curtain.
(1)Install so that the two light curtains emit in the opposite directions

Operating range
Chattering may occur in the output when the distance between the
emitter and the receiver is less than 0.2 m. Use only in the rated
operating range.
(4)Use a spatter protection slit cover. (F3SN and F3SH)
(5)Shorten the detection distance by setting with a setting tool. (F3SJ)
