Making Sensitivity Settings
Two-point Calibration
In this mode, the setting value used will be the mean value of two sensing values
obtained with and without a workpiece.
1
Press the SET button without any workpiece placed in front of the fiber unit.
2
Place a workpiece placed in front of the fiber unit, and press the SET button.
If the sensitivity difference does not have enough room, “
” flashes for about two seconds
after the calibration is complete. The set value is stored in memory even in that case.
Maximum Sensitivity Setting
Set the sensitivity without a workpiece in the case of the reflective model, and with a
workpiece in the case of the through-beam or retro-reflective model.
Press the SET button for three seconds in the state as shown in the above figure.
(Release the button when SET flashes.) The setting value is set slightly higher than
the received light intensity at the time of setting the sensitivity.
Full Auto Calibration
In this mode, the setting value 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.
* FS-V33/V33P only.
* Setting using an external input is up to 1 million times.
* No inputs are accepted while setting each mode.

When external calibration is selected, the operation is the same as with the SET button.
Special Function
By performing the following operation, both sensitivity setting and scaling can be performed using external input.Select external calibration (page 5, No. 5) and display scaling
(page 6, No. 7).The following is the example when using the % calibration.
• After the setting is completed, the setting value is displayed on the digital monitor.
Positioning Calibration
1
Press the SET button without any workpiece placed in front of the fiber unit.
2 Place a workpiece on the position where you want to perform positioning.
Press the SET button for 3 seconds or longer until the display flashes.
Fine-adjusting Sensitivity
The setting value can be directly changed by pressing the manual button.

This is a calibration method that can set the setting value by percentage with reference to the received light intensity at the time of sensitivity setting.
For example, if the target value is set to -10P, the setting value is determined 10%
lower than the received light intensity when the SET button is pressed.
1 When selecting the sensitivity setting method (page 5, No. 2), select the %
calibration, and set the target value of calibration.
2 Taking the desired light intensity as a reference (normally without a
workpiece), press the SET button.
While the % calibration is in use, other calibrations (sensitivity setting) cannot be used.
*
Output Selection
Either light-ON mode or dark-ON mode is selectable.
Dynamic Sensitivity Correction (DSC) Function
DSC automatically corrects the setting value according to the changes in the
received light intensity when there is no workpiece (output OFF).
This function is effective when the light intensity difference is small when judging
whether or not there is a workpiece.
At Detection mode selection (page 5, No.4), select “Dynamic sensitivity correction
mode” beforehand.*
How to set the sensitivity is the same as in the normal mode.
The DSC indicator illuminates when the DSC function is set.

DSC

* When Light ON is selected, the upper limit of the correctable range is twice as
much as the initial setting value.
* The value is stored in memory even after the power is turned off.
* The DSC indicator flashes when the light intensity during output OFF greatly
fluctuates or the L/D ON selection is inappropriate. In such a case, check the
setting again.

Area Detection Mode
This mode is suited to detecting the received light intensity only of a certain range.
To set this mode, select the area detection mode at Detection mode selection (page 5, No.4).

HI: Upper limit setting value
LO: Lower limit setting value
Received light
intensity
Set the value so that the upper limit setting value is larger than the lower limit setting value. The unit does not respond when the upper limit setting value is less
than or equal to the lower limit setting value.
Even when the above condition is satisfied, the unit may not respond when the HI and LO values are close
to each other because of hysteresis. Be sure to operate the unit to check whether the values are valid.
How to Switch the Upper Limit Setting Value (HI) and the Lower
Limit Setting Value (LO)
When the button is pressed, HI or LO and the setting value alternately flash.
When the MODE button is pressed while the display alternately flashes, the HI or
LO display changes. How to configure the sensitivity setting is the same as when
in the normal detection mode.
Setting the Display Scaling
This is the function to adjust the current received light intensity to the ìscaling target value.
1 When selecting a display value correction function (page 6, No. 7), select the
display scaling function, and set the target value. (The explanation here deals
with the case where the target value is set to 2000.)
2
During the normal display, press the SET button while pressing the MODE button.
(Scaling is performed for the current light intensity at this time.)

Edge Detection Mode
This mode detects the change in the received light intensity during a given period
of time. (Set at page 5, No. 4)
Rising edge detection Detects the increase (rising edge) of the
Falling edge detection Detects the decrease (falling edge) of the
Filter Setting
Basically, leave this setting as its initial value. If the passage interval of workpieces
is too short for the unit to respond, strengthen the level and try again.
The selectable filter level differs depending on the power modes.
Filter level HSP* FINE
Default state589999
Setting range 1 to 5 4 to 8 5 to 9 6 to 9 8 to 9 9 only
*HSP: HIGH SPEED
As the number becomes smaller, the filter becomes stronger, which makes the unit difficult to
respond to gradual changes in light intensity.
Making Sensitivity Settings
The sensitivity is set to maximum when the SET button is pressed quickly once.
When the setting value is too low and the unit detects objects other than the workpiece, fine-adjust the setting value to a higher number.

sufficiently clean, a highly accurate detection can
constantly be performed.
Note: Long-ter m use of APC imposes heavier
load on the LED than when disabled.

Limit Setting
This function issues a prediction alarm when the light intensity difference is small
when judging whether or not there is a workpiece.
Two types of limit setting function are available:
Peak limit setting
Samples the peak values of setting value while the received light intensity is
higher than the output 1 setting value, and issues an alarm when the minimum
peak value is lower than the output 2 setting value.
Bottom limit setting
Samples the bottom values of setting value while the received light intensity is
lower than the output 1 setting value, and issues an alarm when the maximum bottom value is higher than the output 2 setting value.

mount the units on the DIN rail (mounted on a metal plate), and keep the output current
within 20 mA.

Hints On Correct Use
• Do not wire the amplifier line along with power lines or high-tension lines, 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.
•I
f 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.
WARRANTY
KEYENCE products are strictly factory-inspected. However, in the event of a failure,
contact your nearest KEYENCE office with details of the failure.
