E3S-C
If reflective Photoelectric Sensors are installed side by side, each
reflective Photoelectric Sensor may be influenced by the light
emitted from the other Photoelectric Sensors.
The fuzzy mutual interference prevention function of the E3S-C en-
ables the E3S-C to monitor any light interference for a certain period
before the E3S-C starts emitting light so that the E3S-C can retrieve
the intensity and frequency of the light interference as data. Using
this data, the E3S-C estimates with fuzzy inference the risk of the
malfunctioning of the E3S-C and controls the timing of the E3S-C’s
light emission.
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 adjustors 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.

Item
Locate a sensing object at the
sensing distance, set the sensitivity
adjustor to the minimum scale
position, and gradually increase
sensitivity by turning the sensitivity
adjustor clockwise until the incident
light indicator (red LED) is ON.
Position A is where the indicator has
turned ON. Regard the maximum
scale position as Position A if the
indicator does not turned ON at full
sensitivity.

LIGHT
(red)
Remove the sensing object and turn
the sensitivity adjustor clockwise until
the E3S-C detects the background
object and the incident light indicator
(red LED) is lit. The moment the red
light indicator is lit, stop turning the
sensitivity adjustor, the position of
which is point B. Turn the sensitivity
adjustor counterclockwise to decrease
the sensitivity until the red light
indicator is OFF. The moment the red
light indicator is OFF, stop turning the
sensitivity adjustor, the position of
which is point C.
If there is no background object, point
C is where the sensitivity adjustor is
set to maximum.

Position B
When the risk is low:
The E3S-C waits until there is no light interference and emits light.
When the risk is high:
The E3S-C emits light between each light interference moment.

Set the sensitivity indicator to the
position between Positions A and C
(in some cases, Positions A and C are
opposite of the above example). The
photoelectric sensor will then work
normally if the stability indicator
(green) is lit with and without the
sensing object. If it is not lit, stable
operation cannot be expected, in
which case a different sensing
method must be applied.
