Procedure
Step 1
Determine position A
Photoelectric sensor
Place target at the desired sensing
distance. Set sensitivity adjuster to the
minimum scale position, and gradually
increase sensitivity by turning the
sensitivity adjuster clockwise until the
Light Incident indicator (red LED)
turns ON. Position A designates the
point at which the LED has turned ON.

Step 2
Determine position B
Remove the target. Starting from the
maximum scale position, gradually
decrease sensitivity by turning the
sensitivity adjuster counterclockwise
until the Light Incident indicator (red
LED) turns OFF. Position B
designates the point at which the LED
has turned OFF.

Step 3
Adjust to optimum setting
Set the sensitivity indicator to the
position between Positions A and B (in
some cases, Positions A and B are
opposite of the above example). To
insure stable sensor operation, the
green stability indicator should be fully
“on” in both the sensing and
non-sensing conditions.
