See "FS-N10 Series User's Manual" for details on the features of the FS-N10 Series and
detailed instructions for configuration.
Hints on Correct Use
Warning
• Do not wire the amplifier line along with power lines or high-tension lines, as the sensor may
malfunction or be damaged due to noise.
• When using a commercially available switching regulator, ground the frame ground terminal
and ground terminal.
• Do not use the FS Series outdoors, or in a place where extraneous light can enter the light-
receiving element directly.
• Due to individual dispersion characteristics and the difference in fiber unit models, the maxi-
mum sensing distance or displayed value may not be the same on all units.
• If the sensor is used for a long time with the APC function enabled and the LED is imposed
with a heavy load, the current consumption of the sensor for light emission will become constant and 'END APC' will be displayed. The sensor can still be used in this case. However,
replace the sensor if even small changes in received light intensity should be detected for
precise detection.

Mounting on a DIN Rail
1 Align the claw at the bottom of the main body with
the DIN rail, as shown in figure1.
While pushing the main body in the direction of
the arrow 1, push down in the direction of arrow 2.
2 To dismount the sensor, raise the main body in
the direction of the arrow 3 while pushing the
main body in the direction of arrow 1.
Installation on a Wall (Main Unit Only)
1 Attach the unit to the optional mounting bracket (OP-
73880), and secure with two M3 screws as shown in
figure2.

• If a thin fiber unit is used, an adapter provided with the thin fiber unit will be
required.
Unless the correct adapter is connected, the thin fiber unit will be loose and
not detect targets correctly (the adapter is supplied with the fiber unit).
• 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.

including the FS-N10 Series, and the network unit NU Series, consult your
nearest KEYENCE dealer.
2 Install the amplifiers on the DIN rail one at a time.
3 Slide the main unit and expansion unit(s) together.
Engage the two claws of the expansion unit with
the recesses on the main unit side until you hear/
feel a click.
4 Attach the end units (option: OP-26751) to the DIN
rail in the same way as step (2).
5 Secure the amplifiers between the end units.
Tighten the screws at the top (two screws x two
units) with a Phillips screwdriver to fix the end
units.

workpiece.
1 Press the [SET] button with no workpiece.
[SET] will be displayed on the sub-menu (green display).
2 Press the [SET] button with workpiece.
The values will be set and the submenu (green display) will flash. The values will be set to
the mid-point between the light intensity when there is no workpiece, and the light intensity
when there is a workpiece.
If "----" flashes for two seconds on the main screen, the light intensity is too small between
conditions when the workpiece is absent and when it is present. These values will be set,
but there is the possibility that detection may become unstable.

Simple, User Friendly Functions
Setting the Current Value to 100.0
With the FS-N10 Series, you can set the current value to 100.0 using simple operations.
Standardizing the current value makes it possible for the sensor amplifiers to instantly differentiate reductions in light intensity and is useful in predicting the need for maintenance.
Note
• The various Preset functions listed below cannot be used when the ZeroShift function is enabled. Disable the Zero-Shift function before executing
the following functions.
• The Preset functions are not suited for transparent workpieces and other
cases of detection with low light intensity differences.
You can disable various Preset functions by pressing and holding the [PRESET]
button.
