Self-diagnostic Function
With this function, the E3S-A checks changes in environmental conditions (especially a change in the ambient temperature) and
self-diagnoses the resistance against the changes. The result is shown by the indicators or an output signal.
External Diagnostic Input Function
To switch the emission off, short-circuit the pink and the blue cords of the emitter of
the E3S-AT or the E3S-AR with the NPN output feature. For the E3S-AT or the E3SAR with the PNP output feature, short-circuit the pink and the brown cords. With this
function, the operating status can be checked before operation.

The sensor is normal if the control output varies when the self-diagnostic 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.
Note:Before using the self-diagnostic external input function, the incident light beam to the sensor must not be
blocked by an object.
Timer and Turbo Switch (Sensors with Self-diagnostic Output Function)
The E3S-A Sensor equipped with the self-diagnostic feature
incorporates 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 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 adjustor of the retroreflective and the 20-cm diffuse 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
Sensitivity Adjustment (Reflective Sensors)
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.

Indicators
Procedure 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.
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.

Turbo Function (Turbo Switch)
With the turbo function switched ON,
the light spot is visible even at a distance of 20 cm, making it easy to
check the sensing position and the
angle of the optical axis.
1. After using the turbo function, readjust the OFF-delay time that had
been set, since the OFF-delay time
could have been changed when
the turbo switch (which is on the
OFF-delay time adjustor) was
pressed.
2. Press the OFF-delay time adjustor
to switch ON the turbo function with
a maximum force of 1 kg and within
a maximum period of 3 mins. (The
photoelectric sensor, however, will
not malfunction even if the turbo
function is switched on for more
than 3 mins.)
Operating Mode Selection
As shown in the following illustration, the E3S-A has an operating mode selector on the panel where the Receiver connector is located. With this operating mode selector, the E3S-A is
in either dark-ON or light-ON mode.

Plug (for E3S-A with connector)
Internal Connection
External connection
Tightening Plug
Turn part B by hand (do not use a pliers or the plug will be
damaged) and tighten it with part C so that length A is nearly
zero. Part B must be tightened properly with part C, or otherwise part B could be loosen by vibration and the sensor will
not maintain the specified enclosure ratings.
Note: Use the spacer (sold together) to mount the photoelectric sensor with or
without the enclosed mounting bracket (refer to Dimensions (page A-
244)).
Precautions
The supplied voltage must be within the rated voltage range.
Unregulated full-or half-wave rectifiers must not be used as
power supplies.
If the input/output lines of the photoelectric sensor are placed
in the same conduit or duct as power lines or high-voltage
lines, the photoelectric sensor could be induced to malfunction, or even be damaged, by electrical noise. Either separate
the wiring, or use shielded lines as input/output lines to the
photoelectric sensor.
Do not use a hammer to hit the amplifier when mounting or the
amplifier will loose watertightness.
Note the following when using the E39-R3, E39-RSA, or E39RSB reflector (tape):
1. Before applying adhesive tape to the reflector, make sure
that the reflector is free from oil or dust, or otherwise the adhesive tape will not stick to the reflector properly.
2. Do not cut the reflector or the reflector will loose watertightness.
3. Do not press the reflector with a metal object or a nail, or
otherwise the reflector will not function properly.
Position of Optical Axis of Through-beam Model
Unlike conventional through-beam models, the E3S Throughbeam Photoelectric Sensor incorporates 2 lenses. But the
lens actually in use is the one marked with an arrow indicating
the position of the optical axis. When using a slit, attach it to
the lens marked with the arrow.

Adjustor Cap
In order to prevent the sensitivity or OFF-delay time that has
been set from changing accidentally enclosed, cover the adjustors with the adjustor cap (enclosed).
Mutual Interference Filter (E39-E6/-E8)
A set of 4 filters are sold together for two through-beam models (for 2 each of emitters and receivers).
For mounting, refer to the figure of the slit for the E3S-A Photoelectric Sensor.
The arrow printed on the cover indicates the direction of polarization. By attaching the filters opposite to each other in polarization to the emitters and the receivers (refer to the figure) in
rows, mutual interference can be prevented (in any case, the
filter attached to an emitter and to the corresponding receiver
must be the same in direction of polarization or the photoelectric sensor will not function).
Mounting Bracket
The direction of the optical axis coincides with the mounting
direction of the E3S when the mounting screw is inserted into
the lock hole of the mounting bracket. Unlike conventional
photoelectric sensors, if the sensing object (or the retroreflector in the case of a through-beam sensor) is in the mounting
direction of the photoelectric sensor, the object is detected
with the incident light without the time-consuming adjustment
of the optical axis (but if the mounting surface is not flat, the
adjustment of the optical axis may still be required).
Note: The maximum tightening torque applied to the screw is 5.5 kgf x cm
(0.53 N x m).
Installation of Accessories
Sensitivity Adjustor Knob (Attachment)
To temporarily use the knob to adjust the sensitivity of the
photoelectric sensor, insert side A into the shaft of the sensitivity adjustor.
To permanently use the knob to adjust the sensitivity of the
photoelectric sensor, insert side B into the shaft (the knob
cannot be removed if once side B is inserted into the shaft).
Slit (E39-S46 Order Separately) for E3S-A
Use the rubber attachment with the metal cover if a slit width
of 2 mm is required. Insert the 0.5- or 1-mm slit between the
metal cover and rubber attachment if a slit width of 0.5 or
1 mm is desired. These slits fit into the rubber attachment.
Note: Apply the slit to the lens of the photoelectric sensor marked with an arrow
indicating the position of the optical axis (apply it to the bottom lens of horizontal sensors and the top lens of vertical sensors).
Optical Axis Reflector (E39-R5 Order Separately)
Use this attachment when the set distance is long and adjustment is mechanically difficult with a sensing object.
Attach the reflector to the receiver (refer to the figure).
Look at the reflector from right behind the emitter. The reflec-
tor should be bright with red light when the optical beam
strikes the reflector. If the emitter has a turbo function, the reflector looks brighter with the function switched on.
When the reflector is removed, the light beam strikes the receiver.
