If any 1 set of series-connected F3SJ is blocked, both of the safety outputs turn OFF. The indication LED for
each F3SJ turns ON separately.
• Number of connections: Up to 4 sets
• Total number of beams: Up to 400 beams
• Connection cable length between 2 F3SJ in series connection: 15m max.

The terms used in this document to describe each F3SJ in a series connection are shown below.
When attaching a cable or cap, tightly fasten the screws (M2, in 4 places, recommended torque: 0.15N  m). Failure to do so may
