OPERATION PROCEDURE
When the power supply is switched on, MODE indicator /
RUN (green) lights up and the digital display shows the
incident light intensity.
MODE key
Press
Press
*1:
When Jog switch is pressed, the setting is confirmed.
*2:
When MODE key is pressed for 2 sec., or more, the sensor returns to the 'RUN' mode.
*3:
Cancellation is possible by pressing MODE key during setting.
*4:
When Jog switch is turned in the 'RUN' mode, the current threshold value is displayed.
And then, the current incident light intensity display appears again automatically.

TEACHING MODE
In case of 2-level teaching
This is the method of setting the threshold value by teaching two levels, corre-
sponding to the object present and object absent conditions. Normally, setting is
done by this method.

In case of limit teaching
This is the method of setting the threshold value by teaching only the object
absent condition (stable incident light condition). This is used for detection in the
presence of a background body or for detection of small objects.
Step
Display
To PRO mode
Note:
The approx. 15% amount of shift is the initial value. The amount of shift can be changed in the
PRO mode from approx. 0 to 80% (5% step). Refer to '
for the setting method.

Press MODE key to light up MODE indicator /
TEACH (yellow).
Press Jog switch in the object present condition.
If the teaching is accepted, the read incident light intensity
blinks in the digital display.
The MODE indicator / TEACH (yellow) blinks.
Press Jog switch in the object absent condition.
If the teaching is accepted, the read incident light intensity blinks in the digi-
tal display and the threshold value is set at the mid-value between the inci-
dent light intensities in the object present and the object absent conditions.
After this, the judgment on the stability of sensing is displayed.
In case stable sensing is possible: '
In case stable sensing is not possible: '
The threshold value is displayed.
The incident light intensity appears in the digital display and the setting is complete.
