This provides useful tips for the feature being descr ibed.
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
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.

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.

Calibration Method

Detecting Even Small Differences

Two-point Calibration

z
Two-point calibration is the basic method of calibration. Press the [SET] button once without the workpiece, and then press it once again with the 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.

Handy Uses for the Preset Function
This function is most useful when performing simple detection using a thru­beam model fiber unit (e.g. completely blocked detection, such as when all
Tip
light axes of the fiber unit are interrupted by opaque workpieces).

Work-Preset Function

z
This function adjusts the current value to "". After executing the Preset function in a condition in which you would like "" to be dis­played, executing this function in a condition in which you would like "" to be displayed, will adjust any two points to "" and "".
The Work-Preset function can be used while the Preset function is in use (when Preset is enabled).
Pressing the [PRESET] button and the button at the same time will set the current value at that time to "". Values that have been set to "" with the Preset function cannot be changed.

Full Auto Preset Function

z
This function automatically differentiates between two conditions (presence/absence of workpiece) and adjusts the current values to "" and "". This is effective for cases when the workpiece is moving at high-speed. Press and hold the [PRESET] button with no workpiece in place. While "#WVQ" is flashing, pass a workpiece through. (Continue pressing the [PRESET] button while the workpiece passes through.)
"
Near-maximum values while the [PRESET] button is being pr essed and held are
adjusted to "" and near-minimum values are adjusted to "" .
The setting value is changed to ""
The green [PST] indicator will light up.
Note
Cannot be executed when the Preset function is already being used (when the [PST] indicator is flashing). Press and hold the [PRESET] button to dis­able the Preset function before executing this function.

Set Current Value to "0"

The Zero Shift Function

z
This function is primarily used with reflective models. Press the [PRESET] button and button at the same time.
When using this function with reflective models, "" will be displayed when there is a workpiece, and "" will be displayed when there is no workpiece, making it easy to know when the workpiece is present or absent. Additionally,
Tip
even when with a reflective model, the background has higher light intensity than the workpiece, if you set a condition with low light intensity to "" using the Preset function and then using the Work-Preset function, register a condi­tion with high light intensity as "", the background will display as "" and when the workpiece is present, it will be displayed as "".

Maximum Sensitivity Preset Function

z
This function sets conditions that will serve as reference, to "" and adjusts conditions with slightly high light intensity as "". This is useful when you would like to perform detection using the background as a reference with reflective models. In the following conditions, press and hold the [PRESET] button for 3 seconds or more then release your finger when "#WVQ" is flashed.
The maximum value for the light intensity while the [PRESET] button is being pressed is
set to ", and light-intensity that is slightly higher than the maximum value at that time will be adjusted to "".
The setting value is ""
The green [PST] indicator will light up.
Cannot be executed when the Preset function is already being used (when the [PST] indicator is flashing). Press and hold the [PRESET] button to dis­able the Preset function before executing this function.
The current value is set to "".
Green "PST" lights up
Note
The zero shift and preset function cannot be used together. To use the preset function, you must first disable the zero shift function.

Disable the Zero Shift Function

z
Press and hold the [PRESET] button to disable the zero shift function.
Handy Uses for the Zero Shift Function
This function is primarily used to set the current value to "0" on a reflective model fiber unit.
Tip
When a reflective model is first installed, the light intensity is sometimes not set to "0". If this happens, using the zero shift function to set the value to "0" when there is no workpiece allows for easier understanding of the difference in light intensity.
Adjusting the current intensity value when it is too large
(when saturated).

Use the Saturation Recovery Function

z
Press the [SET] button while pressing the [MODE] button.
After adjusting the light transmission level and light intensity sensitivity, the current values will be adjusted to within the ranges listed in the table that follows.
Power mode Light intensity setting range
HSP*, FINE, TURBO 2047 ± 350
SUPER 4095 ± 500
ULTRA, MEGA 5000 ± 600
*HIGH SPEED

Disable Saturation Recovery

z
When the saturation recovery function is enabled, press the [SET] button while pressing the [MODE] button to cancel it.
Handy Uses for the Saturation Recovery Function
This function is useful when the intensity value is saturated after installation. This function corrects the saturation via a simple operation, by automatically

Always insert fiber from the side with writing

Cautions for Using a Fiber Cutter

The fiber cutter comes with the fiber unit.
Failure to follow the cautions below could reduce the detection range.
When cutting a fiber unit to be attached to the FS-N10 Series, be sure to use a gray fiber cut-
ter (OP-87098)
Stopping the blade midway could cause a bad cut plane, reducing the detection range.
Do not use the same hole twice.
