position precisely, set the display of sensor amplifier approximate [5000]. The display
changes as follows according to the workpiece position.

Adjusting the Sensitivity

In this manual, the value at which the sensor amplifier's ON/OFF output switches is
expressed as the "setting value". The process of adjusting the setting value is expressed
as "adjusting the sensitivity". This section explains the method of adjusting the sensitivity.

List of Sensitivity Adjustment Methods

The methods of adjusting the LV-N10 series sensitivity is largely classified into 2 types.

(1) Preset
At the same time as adjusting the sensitivity, the received light intensity can be
calibrated to "100.0" or ".0" using simple operations.
This method can decrease the variation of the received light intensity depending on
the contents of the detection and the workpiece, and is useful for predictive
maintenance.
However, this is not suitable for when difference in received light intensity varies little
with or without a workpiece, such as when detecting a transparent workpiece.

(2) Calibration
The sensitivity can be adjusted with simple operations. The received light intensity is
not compensated.
This method is used to adjust without calibrating the received light intensity, or when
highly accurate detection is required.
Calibration can be performed in the preset state.

Percentage calibration

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

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

Basic Operation

Zero shift calibration

This sensitivity setting performs the zero shift function and basic calibration (two-point
calibration / maximum sensitivity calibration / full auto calibration) simultaneously.
The lower of the received light intensity values specified at the time of sensitivity
setting will automatically be set to 0.

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

Percentage calibration and zero shift calibration cannot be set with
channel 2 of the 2-output type models.

Setting the Current Received Light Intensity to 0 (Zero Shift)

Zero Shift Function

This function adjusts the current received light intensity display to "0". It is primarily
used with reflective sensor heads. If the received light intensity cannot be set to "0"
when a reflective model is installed, this function can be used to set the received light
intensity to "0" with no workpiece present. This makes the difference in received light
intensity easier to distinguish.

Enabling the zero shift function

the [PRESET] button and button
simultaneously.

The PST indicator lights in green, and the
received light intensity changes to "0".

Description

To detect a falling workpiece.
The falling edge of the received light intensity is
detected, and output as one-shot.
The received light intensity hold value can be con­firmed by pressing the [MODE] button twice on the
output 1 screen.

To use the external input and periodically compen­sate for the reduction in received light intensity due
to contamination on sensor head face.
A decrease in the light-ON mode's received light
intensity can be detected and output to an external
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 μ10% 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.

DATUM1 mode

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

In DATUM1 mode, the light intensity received
without a workpiece is always corrected to
"100.0". The setting value is also corrected
according to the correction amount, so that the
ratio of setting value and received light intensity
is kept constant, with the result of stable
detection. The display of the setting value does
not change.

The DATUM mode is effective in environments where received light intensity varies
gradually, for example where the sensor head is prone to contamination or large
temperature changes.

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 sensor head.

• To turn the output ON when the received light intensity drops:
Select "~L_d" (Falling edge detection mode)

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

The saturation level can be set in the range of 100P (100%) to 200P (200%) when the
preset saturation function is ON.
For example, if this function is set to 150P, the received light intensity will be corrected
to "150.0" when the preset function is enabled, and the digital display will display
"100.0".
The saturation level can be set to a higher value for stable detection even in
environments which are prone to some contamination, such as dust.
Turn off this function if you want to display values above "100.0" in applications where
the preset function or the DATUM1 mode is used.

Display Function

Fixes the display to "100.0" (displays no value higher than "100.0")

on (ON)

oFF (OFF)

Point

when the actual received light intensity is above 100.0. (Default:
110P)

Displays the actual received light intensity as is, even when it is
above "100.0".

Setting too high of a saturation level (specifying too large a value)
decreases the detectability for small differences in light intensity or
transparent workpieces.

Settings for Advanced Functions

*1 When the detection mode is set to DATUM1, the preset saturation function ON/

OFF state can be selected, but the saturation level will be fixed to 101P (101%),
and the setting screen will not appear.

*2 When the detection mode is set to DATUM2, the preset saturation function set-

ting screen will not appear.

*3 If the preset display mode is set to ArEA when the LV-NH100/NH110/NH300 is

connected, the saturation level is fixed to oFF, and the preset saturation function
setting screen will not appear.

Operating principles of the preset function

(Current received light intensity is 3300 in this example.)

Preset input is used to register the
light intensity as "100.0".

The actual received light intensity (3300)
is set to "110%" and all actual received
light intensities exceeding "100%" are
displayed as "100.0".

When light intensity falls below 100%, a
value lower than "100.0" is displayed.
(The percentage value 110% (i.e., the
saturation level) at the time of registration
can be any value between 100 and

Settings for Advanced Functions

200%.)

If light intensity is not displayed as "100.0"
after preset input, the sensor amplifier is not
in stable detection condition.

Reference

Even when the maximum sensitivity preset function or full auto preset func­tion is used, the preset saturation level setting function operates based on

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)

Point

Reference

• 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 does not work if the eco function is set to
"FuLL"(Full).

• If the number of interference prevention units is set to Std, the number of

units that do not interfere when the LV-N10 Series main unit and expan­sion units connected will be as follows. If set to dobL, the number of units
that do not interfere will be doubled.
When unit other than LV-S31 is connected: 0 units for HIGH SPEED, 2
units for FINE/TURBO/SUPER, and 4 units for ULTRA/MEGA.
When LV-S31 is connected: 2 units for FINE, and 4 units for TURBO/
SUPER/ULTRA/MEGA.

• Consult with KEYENCE for the interference prevention when using the

LV-N10 Series together with other series.

The interference prevention doubles over the Standard
state.

Limit setting output mode

Refer to page 4-3 "2-Output Settings ( )" for setting methods.

Setting output 2 to "LiMt" (limit setting output mode) enables detection of reductions in
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.

again is above the limit setting
value, so output 2 turns OFF if
Auto (Auto) is selected. If USEr

Output
operation

The received light intensity at which
the output turns ON and turn s OFF
is slightly different.

It may be affected by vibration, ther­mal characteristics caused by ther­mal changes, or the state of the
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 con­tamination. When using the thru­beam model or retro-reflective
model, the beam axis may be devi­ated, etc.

The workpiece is either too close or
too far from the sensor.

Eco (ALL) mode is selected.

The power is cut off or the power
cable is disconnected.

Eco (FuLL) mode is selected.

The sleep mode is enabled by the
external input.

The output timer is set.

• When using 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 detec­tion 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 4-30)

• Check that the workpiece is installed within the
adjustment range (50 to 200 mm).

• Place the workpiece at the position to be set as
the detection center, and adjust it so that the
JUST indicator lights in green (or the received
light intensity value is near 5000). (Refer to page
2-7)

• Disable the Eco function.

"Power Save" (page 4-29)

• Disable the Eco function.

• Disable the Eco function.

• Turn the external input OFF, or select a mode
other than sleep mode transition input with the
external input function.

"Sleep mode transition input" (page 4-19)

• Check the output timer setting.

"Output Timer" (page 4-7)

• A slight hysteresis is set to prevent chattering 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.
