3-3 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. (2) Calibration The sensitivity can be adjusted with simple operations.
3-3 Adjusting the Sensitivity Preset Function Enabling the preset function When the PST indicator is not lit, press the [PRESET] button 3 The PST indicator lights in green. The current value is set to "100.0" and the setting value is set to "50.0". Basic Operation Green PST lights up Workpiece Setting value is " . " Current value is " . " Disabling the preset function When the PST indicator is lit, press and hold the [PRESET] button.
3-3 Adjusting the Sensitivity Work-Preset Function This function calibrates the current value to ".0". After the preset function has been executed with "100.0" displayed, and then executing this function with ".0" displayed, 2 random set points can be calibrated to "100.0" and ".0". Enabling the work-preset function Impotant The work-preset function can be used with the preset function (when preset is enabled). The received light intensity at that point is set to ".0". The value set to "100.
3-3 Adjusting the Sensitivity Maximum Sensitivity Preset Function This function calibrates the reference state to ".0" and the state at which the received light intensity is slightly higher as "100.0". This function is useful with the reflective model to detect while using the background as a reference.
3-3 Adjusting the Sensitivity Full Auto Preset Function This function automatically judges 2 states (workpiece presence/absence, etc.), and calibrates the current value to "100.0" and ".0". This is useful when the detector is moving at high speed, etc. Enabling the full auto preset function When the PST indicator is OFF, continue pressing the [PRESET] button until "Auto" flashes while the workpiece passes through. 2 After the workpiece has completely passed through, release the [PRESET] button.
3-3 Adjusting the Sensitivity Disabling the full auto preset function When the PST indicator is lit, press and hold the [PRESET] button. • The PST indicator turns off, indicating that the full auto preset function has been disabled. Point 3 Each preset function cannot be used when the following functions are set. Disable the function or change the setting before executing the preset function.
3-3 Adjusting the Sensitivity Preset display mode (only when LV-N100/NH110/NH300 is connected) The "100.0" (default value) displayed when preset is executed can be changed to "1000" or "3000" * according to the area width. The preset display mode "ArEA" is convenient for displaying the amount of light blocked in the area, etc. * "1000" is displayed when LV-N100/NH110 is connected, and "3000" when LV-NH300 is connected.
3-3 Adjusting the Sensitivity Two-point Calibration Two-point calibration is the most basic method of sensitivity setting. The setting value can be established by simply pressing the [SET] button once each when a workpiece is present. and when it is absent. 1 Press the [SET] button once when no workpiece is present. 2 Press the [SET] button once when a workpiece is present. Calibration is complete after the setting value flashes momentarily, and then stops (lights up).
3-3 Adjusting the Sensitivity Maximum Sensitivity Calibration This sensitivity setting method is useful if the received light intensity is reduced by dust or dirt. The setting value is calibrated to be slightly than the light intensity received when it is determined. 1 When a workpiece is absent for the reflective model, or when a workpiece is present for the thrubeam model/ retro-reflective model, press and hold the [SET] button for 3 seconds or more. Release the button when "SEt" flashes.
3-3 Adjusting the Sensitivity Full Auto Calibration This method automatically sets sensitivity using a moving workpiece. Sensitivity can be easily set by passing a workpiece without shutting down operating equipment. 1 While the workpiece passes through, press and hold the [SET] button until "SEt" flashes. 2 After the workpiece has completely passed through, release the [SET] button. Calibration is complete after the setting value flashes momentarily, and then stops (lights up).
3-3 Adjusting the Sensitivity Positioning Calibration This method is used when you want to position a workpiece. 1 Press the [SET] button once when no workpiece is present. 3 Position a workpiece such that its edge aligns with the center of the projecting beam.

Press the button to adjust the setting value.
3-3 Adjusting the Sensitivity Other Calibration Methods 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. 3 Refer to "Sensitivity Setting" (page 4-4) for details.
3-4 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.
3-4 Setting the Current Received Light Intensity to 0 (Zero Shift) Point Reference The zero shift function cannot be used in combination with the preset function. To use the zero shift function, make sure that the preset function is disabled (the PST indicator is not lit). Zero shift of the expansion unit can be set from the main unit.

6-1 Troubleshooting Frequently Asked Questions Category Trouble Cause Action • Review the installation environment. • The received light intensity can be stably displayed at 100.0 by using the preset function. The received light intensity is inconsistent. How can it be stabilized? It may be affected by vibration, thermal characteristics caused by thermal changes, or the state of the workpiece surface, etc. The received light intensity is too low.
6-1 Troubleshooting Category Trouble A value less than "100.0" is displayed even when the [PRESET] button is pressed. Cause Action The raw received light intensity is 50 or less. * (200 when using the received light intensity expansion setting.) • Press and hold the [MODE] button and check the raw received light intensity level. Try adjusting the beam axis, removing contamination, or reviewing the installation environment. Take actions to raise the original received light intensity.
