maximum performance.
Keep this manual in a safe place after reading it so that it can be
used at any time.
1. Safety Precautions
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 amplifiers in the method shown in the figure
at step 2.
5) Check that the amplifiers are securely sandwiched by the end units. Use a Phillips screwdriver and securely tighten the screws on the
end units (i.e., two screws on each end unit).
4. Connecting Fiber Unit

2. Part Names
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 insertion holes to a length of the fiber insertion 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 multiplecore fiber to the receiver side.
•To remove the amplifiers added, take the steps opposite to the mounting 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.
* The operation indicator of the FS-V22X (infrared model) will not be lit.

● Full Auto Calibration
In this mode, the PV will be set to the mean value of the maximum and
minimum incident values obtained within a certain period.
Use this mode to detect moving workpieces.
1) Press the set button for a minimum of three seconds while the target
workpiece is passing the sensing area of the fiber unit.
• While the set button is pressed, the sensitivity of the sensor will
be set according to the incident values.
• When the setting is finished, the digital monitor will display the PV
in green.
● Two-point Calibration
In this mode, the PV used will be the mean value of two sensing values
obtained with and without a workpiece.
1) Press the set button for a moment without the workpiece in the sensing area (i.e., in front of the fiber unit).
● Manual Calibration
In this mode, make manual PV settings.
● Positioning Calibration
In this mode, a workpiece will be detected when the front edge of the
workpiece has reached a preset position.
1) Press the set button for a moment without the workpiece in the sensing area (i.e., in front of the fiber unit).
2) Locate the front edge of the workpiece in the sensing area. Then
press the set button for a minimum of three seconds.
2) Locate the workpiece in the sensing area (i.e., in front of the fiber unit).
Then press the set button for a moment.
* If there is extremely little difference in sensitivity between the sens-
ing values, the display will flash on completion of tuning.
● Maximum Sensitivity Setting
If the sensing performance of the sensor drops due to dust or dirt, set
the sensitivity of the sensor to maximum.
1) Press the set button without a workpiece if the fiber unit is a reflec-
tive model. Press the set button with a workpiece if the fiber unit is a
through-beam model. In both cases, press the set button for a minimum of three seconds.
7. Selecting Output
Either light-ON mode or dark-ON mode is selectable.
•Take the same steps to set the sensor to light-ON mode again.
8. User-friendly Functions
● Access Mode Selection
Two modes are available to the display of values and menu items.
* If the sensing distance is insufficient, make sensitivity settings in the
sensor in two-point tuning mode.

The following factory settings are made before shipping.
* Returning to factory settings: Press the button for a minimum of
five seconds while pressing the button.
11. Hints On Correct Use
•To extend the cable length, use a cable with at least a 0.3 mm2 crosssection area. Limit the length of cable extension to no more than 100 m.
(To connect several units, contact Keyence for further information.)
• Do not wire the amplifier line along with power lines or high-tension
lines, or otherwise the sensor may malfunction or receive damage 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 surface directly.
• Due to the individual dispersion of characteristics and the difference in
fiber unit model, the maximum sensing distance or displayed value of
all the units are not the same.
• If the sensor is used in S-APC mode for a long time, the LED indicators
will be imposed with a heavy load. In that case, the sensor will be automatically set to ACC mode where the current consumption of the sensor for light emission will be constant, and “END APC” will be displayed.
The sensor can be continuously used in this case. Replace the sensor,
however, if highly precise detection is required.
