3. Amplifier Expansion
Up to 16 expansion units can be connected
to each main unit.
1) Remove the expansion protective cover
from the main unit.
2) Mount each amplifier to the DIN rail.
3) Press the two claws of each expansion
unit to the grooves on the main unit
until the claws snap.
4) Mount the end units to the left- and
right-hand sides of the whole amplifi-
ers in the method shown in the figure
at step 2.
5) Check that the amplifiers are securely sand-
wiched by the end units. Use a Phillips screw-
driver and securely tighten the screws on the
end units (i.e., two screws on each end unit).
4. Connecting Fiber Unit
Fiber insertion sign
1) Open the dust cover in the direction
shown by arrow ➀.
2) Move down the fiber lock lever in the
direction shown by arrow ➁.
3) Insert a fiber unit into the fiber inser-
tion holes to a length of the fiber in-
sertion sign (i.e., approximately 14
mm).
4) Move up and return the fiber lock lever
in the direction shown by arrow ➃.
Note:If a thin fiber unit is used, an adapter provided with the thin fiber unit
will be required.
Unless the right adapter is connected, the thin fiber unit will not
detect targets correctly.

• To connect the coaxial reflective type fiber unit to the amplifier, connect
the single-core fiber to the transmitter side, and connect the multiple-
core fiber to the receiver side.

• To remove the amplifiers added, take the steps opposite to the mount-
ing procedure.
• Put the provided sticker close to the sensor.
Note • The FS-V22/22G/22R(P)/20R/22X incorporates a mutual
interference prevention function, thus allowing the close mounting
of a number of fiber units in the following modes.
