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.
E3S-A
Installation
E3S Sensors equipped with the self-diagnostic feature incorpo-
rates an OFF-delay timer that can be adjusted within range of 0 to
100 ms.
The emitter of the through-beam sensor with the self-diagnostic
feature 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 adjuster of the retroreflective
and the 20-cm diffuse reflective sensor is used as a turbo switch.
When the adjuster 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 adjuster when turning it.
Turbo Function (Turbo Switch)
With the turbo function switched ON, the light spot is visible even
at a distance of 20 cm (7.87 in), making it easy to check the sensing
position and the angle of the optical axis.

that had been set, since the OFF-delay time could have
been changed when the turbo switch (which is on the OFF-
delay time adjuster) was pressed.
SENSITIVITY ADJUSTMENT
TIMER AND TURBO SWITCH
Place target at the desired
sensing distance. Set sensitivity
adjuster to the minimum scale
position, and gradually increase
sensitivity by turning the sensitiv-
ity 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

2. Press the OFF-delay time adjuster to switch ON the turbo
The turbo function is effective with the turbo switch pressed, and
the function is reset automatically when released.
With Turbo Switch ON
The OFF-delay
time adjuster is
used as a turbo
switch (black)
function with a maximum force of 1 kg and within a maximum
period of 3 minutes. (The photoelectric sensor, however, will
not malfunction even if the turbo function is switched on for
more than 3 minutes.)

Step 3
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.
