Operation
J SENSITIVITY ADJUSTMENT
Unlike conventional photoelectric sensors, the variation in the sensitivity of E3S photoelectric sensors is minimal. This means the
sensitivity can be adjusted on only a single photoelectric sensor, and then the adjusters on the other photoelectric sensors can be set to
the same scale position. There is no need to adjust the sensitivity of each photoelectric sensor individually.

Step 1
Determine Position A
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) is 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). The
photoelectric sensor will then work
normally if the stability indicator
(green) is lit with and without the
target. If it is not lit, stable operation
cannot be expected, in which case a
different detection method should be
applied.
