The quick-connection sub cable does not have +V (brown) and 0V (blue).
The power is supplied from the connector of the main cable.
50mA max., if five, or more, amplifiers are connected in cascade.

When Jog switch is pressed, the setting is confirmed.
When MODE key is pressed for 2 sec., or more, the sensor returns to the 'RUN' mode.
Cancellation is possible by pressing MODE key during setting.
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.

The incident light intensity appears in the digital display and the setting is complete.
The threshold value is displayed.
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: '

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 '
PRO MODE / PRO1 mode setting

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.
