3 Basic Operation

① Preset Simple operation allows sensitivity adjustment concurrently with correction of the received light intensity to "100.0" or "0.0" This function helps preventive maintenance by eliminating dispersion of the received light intensity due to the contents of detection or individual workpieces. However, this is not suitable for detection of transparent workpiece because there is a small difference in the received light intensity between presence and absence of a workpiece.

Light emission/Received light intensity adjustment (Saturation Canceling)

When a fiber unit having strong power (longer detection range) is used at a close range, the received light intensity may remain unchanged from the maximum value in the display-enabled range (saturated) regardless of whether a workpiece is present or not. (Example: Numerical value does not change from 9999) In such a case, the light emission and the received light intensity can be automatically corrected to optimal state by using the saturation Canceling function.

(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 ±10% 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.

4-2 Basic Settings

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".

Reference

The light intensity received with a workpiece present will be applied with the same amount of correction as for that received with no workpiece.

The following basic calibrations can be set while in the zero shift calibration. • Two-point calibration • Maximum sensitivity calibration • Full auto calibration

DATUM1 mode Refer to page 4-2 "Detection Settings (Func)" for setting methods. In DATUM1 mode, the light intensity received Received light intensity without a workpiece is always corrected to "100.0". The setting value is also corrected "100.0" according to the correction amount, so that the ratio of setting value and received light intensity Fixed proportion is kept constant, with the result of stable detection. The display of the setting value does "5.0" (Initial value) not change.

Sensitivity setting in DATUM1 mode The sensitivity setting procedure below is an example of two-point 1 100.0 calibration (where the received Setting light intensity is "100.0" when a value 60.0 workpiece is absent and "20.0" when a workpiece is present) using the thrubeam/retro-reflective 20.0 model. 0

Reference

• Output-1 can be configured to be ON (N.O.) or OFF (N.C.) when the received light intensity is above the Lo and under the Hi settings. "Output Switch (L-on/D-on)" (page 3-4) • Area detection can be set just for output-1 scale. Output-2 scale operates according to the "Output 2 detection mode". "Detection Mode for Output2" (page 4-35)

Point

4-14

Always ensure that "upper limit setting value > lower limit setting value". If "upper limit setting value ≤ lower limit setting value", the received light intensity will always be output outside the Hi and Lo range.



Methods for setting upper and lower limits The upper and lower limits can be set using one of the 2 methods: ● Setting sensitivity using the percentage calibration mode See

"Percentage calibration" (page 4-5).

●Sensitivity setting using other calibration modes Sensitivity is set separately for Hi and Lo.

Adjusting Light Emission/Received Light Intensity (Attenuation) Refer to page 4-2 "Detection Settings (Func)" for setting methods. When a fiber unit having strong power (longer detection range) is used at a close range, the received light intensity may remain unchanged from the maximum value in the display-enabled range (saturated) regardless of whether a workpiece is present or not. (Example: Numerical value does not change from 9999) In such a case, the light emission and the received light intensity can be manually corrected to optimal state by using the attenuation function.

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

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. When the detection mode is set to DATUM2, the preset saturation function setting screen will not appear.

Function

• For the preset execution method, refer to "Preset Function" (page 3-6). • Refer to the next page for the detailed operating principle.



Operating principles of the preset function (Current received light intensity is 3300 in this example.) Preset input is used to 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 200%.)

Received light intensity All values in this range are 100.0.

4095 3300 3000 2700

110.0 100.0

90.0

0 (After preset input)

4

If the displayed light intensity falls below "100.0", the preset input can be performed again to restore stable detection. If light intensity is not displayed as "100.0" after preset input, the sensor amplifier is not in stable detection condition.

Received light intensity All values in this range are 100.0.

4095 3300 2970 2700

110.0 100.0

0 (After another preset input for correction)

Reference

Even when the maximum sensitivity preset function or full auto preset function is used, the preset saturation level setting function operates based on the "100.0" point.

System Settings (SYS)

APC function The APC (Auto Power Control) function automatically adjusts the light emission at a constant level. This function reduces variation in the received light intensity due to changes in ambient temperature.

Point

4

• The APC function monitors and adjusts the LED light emission. Therefore, variation in the received light intensity due to contamination or characteristic changes of fiber unit cannot be reduced. When high-precision detection is necessary, also apply the DATUM function and percentage calibration using external input.


DATUM function →

"Detection Mode" (page 4-8)

Percentage Calibration →

"Percentage calibration" (page 4-5)

• If the unit is used for an extend period with the APC function turned ON, heavier load is imposed on the light emitting LED than when the unit is used with the APC function turned OFF. Normally, use the unit with APC turned OFF.

Power Save Refer to page 4-2 "System Settings (SYS)" for setting methods. Power consumption can be reduced by turning off the digital display and output indicators. Function

oFF (OFF)

Disables the power save function. (Default) Enables the power save function. (A single segment pulses across the digital display.) Reduces power consumption. (The power save function is ON, and response time is 4 times longer.) Eco ALL (The digital display and output indicators are all off).

on (ON) FuLL (FULL)

ALL (ALL)

This item becomes selectable by pressing and holding while FuLL is lit. The power consumption in Eco ALL is the same as that in Eco ON.

Immediately after the ON or FULL option is selected, the option is enabled, and the power save display results. The normal display is restored after any key is operated (except for eco ALL). If no operation is made for the next 30 seconds, the power save display returns.

Point

When FuLL is selected, response time is 4 times as long as usual (i.e., as compared to when oFF or on is selected). When ALL is selected, response time is the same as usual.

Deactivating eco ALL

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. Function Normal operation (Default) The interference prevention doubles over the Standard state.

dobL (Double)

Point

• 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 cannot be set if the eco function is set to “FuLL (Full)”.

„ Maximum number of interference prevention units Number of units prevented from interference during the connection of the main and expansion units of the FS-N10 Series is as follows.

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. How can it be increased?

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.

"Preset Function" (page 3-6) • 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)

Received light intensity display

The received light intensity remains unchanged from 4095 or 9999 even if a workpiece is placed for detection. When used under extremely short conditions of the detection range, the received light intensity decreases.

6

• 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 4-32) • Extend the detection range. • Lower the light emission level and the received light intensity.

The received light intensity has become too large.

"Light emission/Received light intensity adjustment (Saturation Canceling)" (page 3-18) "Adjusting Light Emission/Received Light Intensity (Attenuation)" (page 4-20) • Disable the Eco function.

Eco (ALL) mode is selected.

Appendix

"Power Save" (page 4-31)

Nothing is displayed. The power is cut off or the power cable is disconnected.

• Disable the Eco function. • Disable the Eco function.

Screen display

The sleep mode is enabled by the external input.

• Turn the external input OFF, or select a mode other than sleep mode transition input with the external input function. "Sleep function" (page 4-19) • Check the output timer setting.

The output timer is set. "Output Timer" (page 4-7) Output operation

6-2

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

Hysteresis

• 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.


6-1 Troubleshooting

Category

Trouble

Cause The raw received light intensity is 50 or less. * (200 when using the received light intensity expansion setting.)

A value less than "100.0" is displayed even when the [PRESET] button is pressed.

Action • 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. • Preset the maximum intensity again after lowering the received light intensity.

The maximum intensity is preset with the received light intensity almost saturated.

"Light emission/Received light intensity adjustment (Saturation Canceling)" (page 3-18) "Adjusting Light Emission/Received Light Intensity (Attenuation)" (page 4-20) • Disable the zero shift function.

The zero shift function is enabled. "Zero Shift Function" (page 3-16) The zero shift calibration (0SEt) is selected as the sensitivity setting.

Preset related

• Select the sensitivity setting other than the zero shift calibration. "Sensitivity Setting" (page 4-4)

The rising / falling edge detection mode is selected.

• Select the detection method other than the rising / falling edge detection mode. "Detection Mode" (page 4-8)

When each preset function is executed, "---- ----" appears, and no change is seen.

Zero shift input is selected with the external input function.

• Select a mode other than zero shift input for the external input function. "External Input" (page 4-17)

The difference in received light intensity during preset function execution and workpiece preset function execution is small.

• Make sure that the received light intensity does not exceed the values listed in the "Display Gain" (page 4-32). • Cancel each preset function.

The preset function is enabled. "Preset Function" (page 3-6) "---- ----" appears even when using the zero shift function, and each preset function with no effect is being used. Zero shift related

Preset input is selected with the external input function.

• Select a mode other than preset input with the external input function. "External Input" (page 4-17)

The rising edge detection/falling edge detection mode is enabled.

• Set a detection mode other than rising edge detection/falling edge detection mode with the detection mode settings.

The DATUM1/DATUM2 mode is enabled.

• Set a detection mode other than DATUM1/ DATUM2 mode with the detection mode settings.


Nothing happens even when the zero shift function is used.


DATUM related

Sensitivity setting (calibration) related

The received light intensity is not calibrated to 100.0/.0 in the DATUM1/2 modes.

Pressing the [SET] button has no effect.

The raw received light intensity is 50 or less. * (200 when using the received light intensity expansion setting FuLL)

• 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.

The raw received light intensity is less than the warning output level.

• Check the installation environment and confirm that the beam axis has not deviated and that the workpiece surface is not contaminated. • To continue calibration, increase the warning output level value. Calibration will not stop as frequently.

The sensitivity setting (calibration) is restricted in specific detection modes.

• Change the detection mode or sensitivity setting referring to "Restrictions for Sensitivity Settings in Each Detection Mode" (page 6-9).
