Making Sensitivity Settings

■ 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 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 type, and with a
workpiece in the case of the through-beam or retro-reflective type.

Press the SET button for three seconds in the state as shown in the above figure.
(Release the button when SET flashes.)

When setting the sensitivity, set the value slightly higher than the received light intensity.

■ 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.

• 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.

Percentage (%) Calibration

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 4, 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.

* With FS-V31C(P)/32C(P), by periodically performing external calibration from

PLC or other devices, stable detection can be performed even with a small
sensitivity difference.

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 4, 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.

* 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.

Edge Detection Mode

This mode detects the change in the received light intensity during a given period
of time.

■ 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.

*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.

■ Operation When Switching Outputs

When extension display (page 5, No.8) is set for the number of digits to be
displayed for the received light intensity

1

Press the manual button quickly once, and check that the setting value flashes.

2

While the setting value is flashing, change the setting value with the Manual button.

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 4, No.4).

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.

■ 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 alter nately 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 5, No. 6), select the

display scaling function, and set the target value.

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.)

The reference light intensity can be set in the following range in reference with the
currently received light intensity:

• No value can be set when the Edge detection mode is selected.

• The value is stored in memory even after the power is turned off.

• The value is not reflected to the analog output of the FS-V31M.

• When using FS-V31C(P)/32C(P), external inputs can be used.

Zero-shift Function

The Zero-shift function is used to forcibly set the current light intensity to zero.

1

At Display value correction function selection (page 5, No.6), select “Zero-shift function”.

2 When the SET button is pressed while the MODE button is pressed, the current

light intensity is forcibly set to zero.

• This function cannot be used when the Dynamic sensitivity correction (DSC) or

Edge detection mode is selected.

• The value is stored in memory even after the power is turned off.

• The value is not reflected to the analog output of the FS-V31M.

• When using FS-V31C(P)/32C(P), external inputs can be used.

External Input [Function only for FS-V31C(P)/V32C(P)]

1

Signals can be input externally by selecting an exter nal input function (page 4, No. 4-C).

2

The signal can be accepted by short-circuiting the pin (2) for 2 ms or more as
shown below for each model (20 ms for OFF).

* For FS-V31C/31CP 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 4, No. 4-C) and
display scaling. The following is the example when using the % calibration.

Display Selection

The factory default value is “1” only. Other items can be displayed only after being
selected at Display customization selection (page 5, No.8).

*1 When ULTRA/MEGA mode is selected, the current received light intensity can

be displayed up to 5 digits.
The setting value flashes when the

button is pressed once.

The setting can be changed by pressing the button while flashing.
*2 The excess gain is displayed in a 5% increment from 85 to 115%.
*3 The current light intensity for the setting value is displayed in percentage.
*4 Holds and displays the peak value and the bottom value.

How to reset the peak and bottom values (with the 5/6 display)

While pressing the MODE button, press the SET button for 3 seconds or longer to reset
the peak and bottom values. Turning the power off also resets the values.
With FS-V31C(P)/32C(P), the value can be reset externally by selecting Reset at
External input function selection (page 4, No.4-C).

■ User-friendly Functions (Direct Access Menu)

The hold display (5/6) can be set in detail by pressing the button for 2 seconds or longer.

The power mode and attenuation function for the power mode display (3) can be
set by pressing the button for 2 seconds or longer.

Key Lock Function

The key lock function disables the operation of all keys.

1

While pressing the MODE button, press the ( ) button for at least three seconds.

The same steps can be taken to deactivate key lock.
For more information on the key lock levels and the PIN number key lock function,
refer to page 6.

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.

About APC (Auto Power Control)

In normal cases, use the sensor with APC
disabled.
When APC is enabled, the light intensity is
monitored and corrected in order to maintain
regular light transmission. If the environment is
sufficiently clean, a highly accurate detection can
constantly be performed.
Note: Long-term use of APC imposes heavier

load on the LED than when disabled.

number of units to be connected.When connecting several units, be sure to mount the units on
the DIN rail (mounted on a metal plate), and keep the output current within 20mA.
When 1 to 2 units are connected : -10 to +55 °C,
When 3 to 10 units are connected : -10 to +50 °C,
When 11 to 16 units are connected : -10 to 45 °C

PIN Number Key Lock Function

The unit can be locked using a PIN number to ensure securer locking effect.

1 While pressing the MODE button, press the

( )

button 10 times.

2 Select a PIN number between 0 and 9999 using the button.
3 Press the MODE button to activate key lock.

Follow the same step to disable the key lock. Use the same PIN number used for
locking.

Note

Write down the PIN number in case it is forgotten.
The key lock cannot be disabled unless the correct PIN number is used.

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.

• If 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.
