Hints on Correct Use

• Do not use this product in saf ety circuits for human pr otection.

• This product is not ex plosion-proof. Do not use the product in
places with flammable gas, liquid, or dust.

• This product uses DC power. Do not apply AC power. The
product may explode or burn if an AC voltage is applied.

•Do not wire the amplifier line along with power lines or high-tension lines, as the
sensor may malfunction or be damaged due to noi se.

• When using a commercially a vailable 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 maximum 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 use
received light intensity should be detected for precise detection.

Adjusting Sensitivity

This manual refers to the values that select ON/OFF output of the sensor amplifiers as
"Set values." In addition, the manual refers to the adjustment of set values as "Adjusting
Sensitivity." This section describes the sensitivity adjusting method.

List of Sensitivity Adjusting Methods

Sensitivity adjusting method for the FS-N10 Series is broadly divided into two categories:

① Preset
Simple operation allows sensitivity adjustment concurrently with correction of the
received light intensity to "100.0" or "0.0"
This function helps preventive maintenance by eliminating dispersion of the received
light intensity due to the contents of detection or individual workpieces.
However, this is not suitable for detection of transparent workpiece because there is a
small difference in the received light intensity between presence and absenc e of a
workpiece.

② Calibration
Sensitivity can be adjusted by a simple operation. This function does not correct t he
received light intensity.
This function is applied for using the received light intensity without correction or for
high-precision detection.
Calibration is also available in a preset state.

Percentage calibration

A setting value is established with a percentage in respect to the current received light
intensity. When a sensor amplifier equipped with an external input is used,
percentage tuning can be performed from an external device, such as PLC, allowing
highly accurate detection of transparent workpieces and small workpieces, etc.

Refer to "Sensitivity Setting" (page 4-4) for details.

Zero shift calibration

This sensitivity setting performs the zero shift function and basic calibration (two-point

When a fiber unit having strong power (longer detection range) is used at a close
range, the received light intensity may remain unchanged from the maximum value in
the display-enable d range (saturated) regardless of whether a workpiece is present or
not. (Example: Numerical value does not change from 9999)
In such a case, the light emission and the received light intensity can be automatically
corrected to optimal state by using the saturation Canceling function.

source by using the 2-output type's output 2.

To use the external input and "0" the light intensity
received without a workpiece present.
The background received light intensity is set as 0
even when calibrating with the buttons on the display.
(Zero Shift calibration)

To 0 the lower of level received light intensity values
in order to display higher values of received light
intensity.
The display can be extended up to 5 digits by press­ing the [MODE] button twice on the output 1 screen.

This is recommended when outputting within a spe­cific received light intensity range. When the [SET]
button is pressed once at the reference received light
intensity, the upper/lower setting value limits will be
set at ±10% from the reference received light inten­sity.

This is recommended when detecting a transparent

workpiece. The received light intensity at the state
with no workpiece is set as ".0", and the displayed
value is increased as the amount of light blocked by

the workpiece increases.
When the [SET] button is pressed or when calibrated
with external inputs, the received light intensity -5%
at that point is set as the setting value.

Methods for setting upper and lower limits

The upper and lower limits can be set using one of the 2 methods:

● Setting sensitivity using the percentage calibration mode

See "Percentage calibration" (page 4-5).

●Sensitivity setting using other calibration modes

Sensitivity is set separately for Hi and Lo.

Press to display "Hi" or "Lo".

The "Hi" or "Lo" value, and the current set-
ting values are displayed alternately.
When the [MODE] button is pressed while
the display alternately flashes, the "Hi" or
"Lo" display changes.
If you do nothing for 3 seconds or more,
the received light intensity display is auto-
matically restored.

Press the [SET] button to perform sen-

Edge detection mode

Refer to page 4-2 "Detection Settings (Func)" for setting methods.

In the edge detection mode, the sensor amplifier detects changes of received light
intensity over a fixed period.
This mode is used to turn on the output only when a workpiece is moving into or out of
the detection range of the fiber unit.

• Turning the output ON when the received light intensity attenuates.
→ Select "~L_d" (Falling edge detect mode)

• To turn the output ON when the received light intensity increases:
→ Select "_|~d" (Rising edge detect mode)

Settings for Advanced Functions

Timing chart

When the falling edge detection mode is selected with a thrubeam model:

(1), (3):

The output is OFF because the
received light intensity is not
changing.

(2) :

The output is ON because the
received light intensity is decreasing.

(4) :

The output remains OFF because
the received light intensity is
changing but is increasing.

Combining the edge detection mode and any of the functions below
makes it more difficult to detect gradual changes in light intensity.

The amplifier is now configured to ignore
changes in received light intensity for the dura-
tion that the [SET] button is pressed.
Calibration is complete after the setting value
flashes momentarily , and then stops (lights up).

• When detecting workpieces run-

ning on a conveyor, the [SET] button can be pressed for a longer period
to ignore the fluctuations of recei ved light intensity due to con veyor vibra-
tion.

• If the setting value is so low that objects other than the workpiece of interest

are also detected, fine adjustments can be made with the button.

Once the sleep mode is entered, the following events occur.

• The display of received light intensity and
setting value goes out.

• Light transmission stops.

• The output is turned off (for both L-on and

Writing of External Input to EEPROM

Setting "no" to the "Writing of External Input to EEPROM" when any of "Set (External
Tuning Input)", "PrSt (Preset Input)" or "ShFt (Zero Shift Input)" is selected, the setting
modified by the external input will not be written to EEPROM.
This prevents frequent wr iting to the EEPROM when inputting external signals and
thus prevents the EEPROM from reaching the end of its service life (approx. 1 million

Adjusting Light Emission/Received Light Intensity (Attenuation)

Refer to page 4-2 "Detection Settings (Func)" f or setting methods .

When a fiber unit having strong power (longer detection range) is used at a close
range, the received light intensity may remain unchanged from the maximum value in
the display-enable d range (saturated) regardless of whether a workpiece is present or
not. (Example: Numerical value does not change from 9999)
In such a case, the light emission and the received light intensity can be manually
corrected to optimal state by using the attenuation function.

Interference Prevention

Refer to page 4-2 "System Settings (SYS)" for setting methods.

Malfunction may result from "interference", a phenomenon in which light transmission
occurs simultaneously with any other sensor amplifier.
However, when the number of sensor amplifiers increases, the light transmission
timing automatically shifts and prevents this interference.
Setting this function to "dobL" (Double) on all of the connected amplifier units doubles
the number units that do not mutually interfere.

Display Function

Std (Standard) Normal operation (Default)

dobL (Double)

• Selecting "dobL" also doubles response time over the "Std" state.

• When selecting "dobL", the main unit and its connected expansion
units must all be set to "dobL".

• This function cannot be set if the eco function is set to “FuLL
(Full)”.

 Maximu m number of interference prevention units

Number of units prevented from interference during the connection of the main and
expansion units of the FS-N10 Series is as follows.

Setting output 2 to "LiMt" (limit setting output mode) enables detection of reductions i n
received light intensity for output 1. Specifically, if the cumulative minimum of peak
value for output 1 falls below the limit setting value, it is recognized as a reduction in
received light intensity and therefore output 2 is turned on.

workpiece surface, etc.

This may be the result of a long
detection distance. When using the
reflective model, the intensity of the
light reflected from the workpiece
may be low, or there may be con-
tamination. When using t

"Preset Function" (page 3-6)

• When us ing the DATUM1/2 mode, the set value
and received light intensity are both calibrated to
maintain a set ratio.

"Detection Mode" (page 4-8)

•Review the installation environment and detec-
tion distance.

• The received light intensity value can be
increased by raising (delaying) the power mode.

"Power Modes" (page 4-4)

• The apparent received light intensity can be
increased 4-fold by using the light intensity
expansion setting.

"Display Gain" (page 4-32)

• Extend the detection range.

•Lower the light emission level and the received
light intensity.

• A slight hysteresis is set to prevent chatter ing in
the output. If this level of received light intensity
is notable during detection, the detection toler­ance may be low. Please review the detection
details.
