3. Amplifier Expansion
Up to 16 sub 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 sub unit to the grooves on the main unit until
the claws snap. 
4) Mount the end units to the leftand 
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 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
1) |
Open the dust cover in the direction |
|
shown by arrow . |
2) |
Move down the fiber lock lever in the |
|
direction shown by arrow . |
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). |

Move up and return the fiber lock lever |
|
in the direction shown by arrow . |
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 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)/22X incorporates a mutual interference prevention function, thus allowing the close mounting of a number of fiber units in the following modes.

6.Making Sensitivity Settings
●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.
Workpiece
The display will 3 s min. flash when the
settings are completed.
•When the setting is finished, the digital monitor will display the PV in green.
PV (green) |
CV (red) |
●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).
Workpiece
The display will be lit when the workpiece is detected.
2)Locate the workpiece in the sensing area (i.e., in front of the fiber unit). Then press the set button for a moment.
Workpiece 
The PV will appear when
the settings are completed.
* If there is extremely little difference in sensitivity between the sensing 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 reflective 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.

“Through-beam model”
3 s min.
The display will flash for a moment when the setting is finished. Then the PV will be displayed.
* If the sensing distance is insufficient, make sensitivity settings in the sensor in two-point tuning mode.
●Manua| Calibration
In this mode, make manual PV settings.
PV 
The PV value decreases by pressing this side of the manual button.
● Positioning Calibration
The PV value increases by pressing this side of the manual button.
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).
Workpiece
The display will be lit when the workpiece is detected.
2) Locate the front edge of the workpiece in the sensing area. Then press the set button for a minimum of three seconds.
