Operation 1
The Basics of Sensitivity Adjustment
1 Two-point Calibration
With this method, the FS -NEO Series detects two points (with and without a workpiece present) and sets the intermediate
point as the setting value.
OPERATING PROCEDURE
(1) Make sure that the display shows the setting value/current value.
(2) Press the [SET] button once with no workpiece present.
(3) Press the [SET] button once with a workpiece present.

2 Fully Automatic Calibration
With this method, the FS -NEO Series sets the intermediate value between the maximum and minimum received light
intensity within a certain period of time.
Do you have trouble adjusting the sensitivity for applications where a workpiece that is narrower than the optical axis
diameter continuously passes through the light beam? In such a case, fully automatic calibration will enable more stable
detection.
OPERATING PROCEDURE
(1) While holding down the [SET] button for 3 seconds or longer, let the workpiece(s) pass through the beam. The
sensitivity is set based on the maximum and minimum light intensity received while the [SET] button is pressed down.

3 seconds or longer
After the calibration is complete, the setting value is displayed in green on the digital monitor.

The Basics of Sensitivity Adjustment
3 Maximum Sensitivity Setting
[For thrubeam models] When a workpiece is larger than the fiber strand diameter (lens diameter), the light is
completely blocked. This method is used to set the sensitivity when the workpiece is large
enough to completely interrupt the light.
[For reflective models] This method is used to set the maximum sensitivit y while still ignoring the background.
OPERATING PROCEDURE
(1) Make sure that the display shows the setting value/current value.
(2) [For thrubeam models] Press and hold the [S ET] button for 3 seconds or longer with a workpiece present between
the transmitter and receiver fiber units.

4 Fine Adjustment
Set the sensitivity manually.
OPERATING PROCEDURE
(1) Make sure that the display shows the setting value/current value.
(2) While monitoring the current value display, press the manual buttons to perform fine adjustment of the setting value.

5 Positioning Calibration
With this method, the FS -NEO Series detects the workpiece exactly when its edge reaches the predetermined position.
OPERATING PROCEDURE
(1) Make sure that the display shows the setting value/current value.
(2) Briefly press the [SET] button with no workpiece present.

Simplified Sensitivity Adjustment
6 Preset Function
One simple click of the button will make all the displays uniform and set the sensitivity at the same time.
OPERATING PROCEDURE
After installing the sensor, briefly press the [PRESET] button with no workpiece present when using a thrubeam model
(or with a workpiece present when using a reflective model).
Pres s the [PRESET] but ton once with no
workpie ce present.

The received light intensity is adjusted to 100.0 and
the setting value is adjusted to 50.0.
The setting is complete with just one click.
The setting value is
displayed a s “50.0”.
The current value is
displayed as “100.0”.
7 Saturation Recovery Function
When setting a reflective model, this function automatically adjusts the light intensity from a level that is too intense,
which prevents light intensity differences from being detected, to a lower value that allows for proper, reliable detection.
OPERATING PROCEDURE
After installing the sensor, briefly press the [MODE] button and [SET] button at the same time.
Pres s the [MO DE] button an d [SE T] b utton
