6. Making Sensitivity Settings

G 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.

3 s min.

The display will

flash when the

settings are

completed.

• When the setting is finished, the digital monitor will display the PV

in green.

G 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 for a moment without the workpiece in the sens-

ing area (i.e., in front of the fiber unit).

The display will be lit

when the workpiece

is detected.

2) Locate the workpiece in the sensing area (i.e., in front of the fiber unit).

Then press the set button for a moment.

The PV will appear when

the settings are completed.

* If there is extremely little difference in sensitivity between the sens-

ing values, the display

will flash on completion of tuning.

G Maximum Sensitivity Setting

If the sensing performance of the sensor drops due to dust or dirt, set

the sensitivity of the sensor to maximum.

1) Press the set button without a workpiece if the fiber unit is a reflec-

tive model. Press the set button with a workpiece if the fiber unit is a

through-beam model. In both cases, press the set button for a mini-

mum of three seconds.

3 s min.

The display will flash

for a moment when

the setting is finished.

Then the PV will be

displayed.

“Reflective model”

“Through-beam model”

* If the sensing distance is insufficient, make sensitivity settings in the

sensor in two-point tuning mode.

G Manual Calibration

In this mode, make manual PV settings.

PV

The PV value decreases by pressing

this side of the manual button.

The PV value increases

by pressing this side of

the manual button.

G Positioning Calibration

In this mode, a workpiece will be detected when the front edge of the

workpiece has reached a preset position.

1) Press the set button for a moment without the workpiece in the sens-

ing area (i.e., in front of the fiber unit).

The display will be lit

when the workpiece

is detected.

2) Locate the front edge of the workpiece in the sensing area. Then

press the set button for a minimum of three seconds.

3 s min.

The display will flash

for a moment when

the setting is

finished. Then the

PV will be displayed.

7. Selecting Output

Either light-ON mode or dark-ON mode is selectable.

Press the output selector.

The display indicates that

the sensor is in dark-ON

mode. The CV will be

displayed if no buttons are

operated for approximately

five seconds.

Press the manual button
