E3S-A/B
The E3S-A Sensor equipped with the self-diagnostic feature incor-
porates an OFF-delay timer that can be adjusted within a range of 0
to 100 ms.
The emitter of the through-beam sensor with the self-diagnostic fea-
ture incorporates a turbo switch. When this switch is on, the intensity
of the red LED light source can be increased to make a brighter spot.
The OFF-delay time adjustor of the retroreflective and the 20-cm dif-
fuse reflective sensor is used as a turbo switch. When the adjustor is
pressed, it functions as a turbo switch to automatically increase the
power of the light source to create a brighter light spot. Do not press
the adjustor when turning it.
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.

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.

Remove the sensing object and
gradually decrease sensitivity by
turning the sensitivity adjustor
counterclockwise from the maximum
scale position until the incident light
indicator (red LED) is OFF. Position B
is where the indicator has turned off.
Regard the minimum scale position as
Position B if the indicator does not
turned ON at minimum sensitivity.

The sensor is normal if the control output varies when the self-diag-
nostic external input is ON and OFF. The sensor is abnormal if the
control output does not vary when the self-diagnostic external input
is turned ON or 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
sensing object. If it is not lit, stable
operation cannot be expected, in
which case a different detection
method must be applied.
