Make sure that detection may become unstable if less margin is applied in the use

In case of 2-point teaching
● This is the method of setting the threshold value by teaching two points, corre-
sponding to object present and object absent conditions. Normally, setting is done
by this method.
● The output operation setting of Light-ON or Dark-ON is reflected automatically.

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.
● When selecting "Auto" (displayed with " ") in the emission amount setting mode, proper light
intensity can be automatically set. For the setting method, refer to "
