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.

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.

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.

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.
