## 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

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.

A-242
## 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.)
## **With Turbo Switch ON**
The turbo function is effective with the turbo switch pressed, and the function is reset automatically when released.

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.

Tightening Plug
(B) (C) (A) 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

## 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.

**----- Start of picture text -----**<br>
Emitter<br>!<br>Receiver<br>Be aware of the direction of<br>. polarization.<br>**----- End of picture text -----**<br>
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).

## 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.

Attach the reflector to the receiver (refer to the figure). Look at the reflector from right behind the emitter. The reflector 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.
