
Disable the Zero Shift Function
Press and hold the [PRESET] button to disable the zero shift function.
Output Switch
Either light-ON (L-on) mode or dark-ON (D-on) mode can be selected.
1
While the current value is displayed,
press the [MODE] button once.
2
Use to switch the output (  /  ), then press the [MODE] button again.
The output change completes, and the display returns to the current value.
Display when the LV-S31 is Connected
When the LV-S31 is connected, the workpiece position is numerically displayed on the main
screen (red display) using the center position as [5000].
The display changes as follows according to the workpiece position.
Initializing the Settings

Initialization Method
1
Press and hold the [SET] and
[PRESET] buttons simultaneously
for more than three seconds.
2
Use the to select "  ", then press the [MODE] button.
3
Use the to select "  ", then press the [MODE] button.
After initialization is complete, the display returns to the current value.

Initial Settings
Key Lock
The key lock function disables button operation to prevent unauthorized use.

Activating Key Lock
1
Press and hold the [MODE] button
and
(or ) simultaneously for
three seconds or more.
2
The screen displays "  ", disabling
key operation.

Deactivating Key Lock
1
Press and hold the [MODE] button
and
(or ) simultaneously for
three seconds or more.
2
The screen displays "  ", enabling
key operation.

Connecting to External Devices

Cable Type
The light intensity may not be set to "  " when the reflective model sen-
sor head is first installed.
In this case, using the zero shift function to set the state with no target
present to "
 " will make it easier to see the difference in light intensi-
ties.
• When LV-S31 is connected  (side farther from the sensor is
ON) or  (side nearer the sensor is ON) can be selected.
• When using the 2-output type, output 1 and 2 can be set indi-
vidually.
Display Meaning
 Out of detection range
 The detector is nearer to the sensor side than numerical display range

Centering on 5000, the value increases as the workpiece distance
increases from the sensor

The workpiece is farther from the sensor than the numerical display
range
 Out of detection range


Overcurrent in the control out-
put.
• Check the load and return the cur-
rent within the rated range.
• Check that the output wire is not
contacting any other wire or frame.

Sensor head cable is broken or
is not connected.
• Check that the sensor head is
connected.
• Check sensor head cable for dam-
age.
• Check the sensor head cable con-
nector for damage or loose con-
nections.
After checking, turn the power
OFF and ON.
 Internal data write / load failed.
Turn the power OFF and ON. If the
data is not recovered, initialize the
settings.

Key lock function is enabled, or
if using M8 connector types or
monitor output types, the
power mode was fixed to
MEGA mode using the selec-
tor switch. • Release the key lock.
• Check that the sensor amplifier
selector switch is set to MEGA
mode.
The DTM indicator
flashes.
Correction error in DATUM1 or
DATUM 2 mode. See "LV-N10 Series User’s Manual"
for details.
