FUZZY LOGIC MUTUAL INTERFERENCE PREVENTION FUNCTION
(FOR E3S-CR

AND E3S-CD

ONLY)
Ifphotoelectricsensorsareinstalledsidebyside, eachSensormay
be influenced (or malfunction) by the light emitted from the other
sensors. This is known as mutual interference.
The fuzzy logic mutual interference prevention function of the
E3S-C enables the E3S-C to monitor light interference over a cer-
tainperiodoftime.BeforetheE3S-Cstartsemittinglight,theE3S-C
retrieves the intensity and frequency of surrounding light interfer-
enceasdata.Usingthisdata,theE3S-Ccalculates,withfuzzyinfer-
ence,theriskoftheE3S-Cmalfunctioningandcontrolsthetimingof
the E3S-C’s light emission.
When the risk is low, the E3S-C waits until there is no light interfer-
ence and emits light.

Procedure 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) turns 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 guaranteed,in which case a
different detection method should be
applied.
Unlike conventional photoelectric sensors, the variation in the sensitivity among several E3S-C photoelectric sensors is minimal. This
means the sensitivity can be adjusted on only a single photoelectric sensor, and then the adjusters on the other E3S-C photoelectric sen-
sors can be set to the same scale position. There should be no need to adjust the sensitivity of each photoelectric sensor individually.
