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.
## I **TIMER AND TURBO SWITCH**
E3S Sensors equipped with the self-diagnostic feature incorporates 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.
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 OFFdelay time adjuster) was pressed.
2. Press the OFF-delay time adjuster to switch ON the turbo 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.)
The turbo function is effective with the turbo switch pressed, and the function is reset automatically when released.

## **Self-Diagnostic Function**
With this function, the E3S-A sensor 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.

## I **EXTERNAL DIAGNOSTIC INPUT FUNCTION**
To switch the emission off, short-circuit the gray (pink) and the black (blue) cords of the emitter of the E3S-AT❑ or the E3S-AR❑ with the NPN output feature. For the E3S-AR❑ with the PNP output feature, short-circuit the gray (pink) and the red (brown) cords.
NOTE: IEC colors are shown in parentheses.

## I **SLITS FOR THROUGH-BEAM SENSORS**
## **E39-S46 Slit Set**
Using slits allows smaller objects to be detected and reduces the sensing distance.

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.

## I **OPTICAL AXIS CONFIRMATION REFLECTOR E39-R5**
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 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.

## I **E39-E6 MUTUAL INTERFERENCE FILTER**
A set of 4 filters are sold together for two through-beam models (for 2 each of emitters and receivers).
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).
