Procedure
Place target at the desired sensing distance. Set sensitivity adjuster to the minimum scale position, and gradually increase sensitivity by turning the sensitivity 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 turning the sensitivity adjuster counterclockwise until the Light Incident indicator (red LED) turns OFF. Position B designates the point at which the LED has turned 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 target. If it is not lit, stable operation cannot be expected, in which case a different detection method should be applied.
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.
s 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. With Turbo Switch ON Normal Operating Condition

Self-Diagnostic Function
E3S-A
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.

s 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-ATu or the E3S-ARu with the NPN output feature. For the E3S-ARu with the PNP output feature, short-circuit the gray (pink) and the red (brown) cords.

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).

s 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. When the reflector is removed, the light beam strikes the receiver.

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).
