15 Installation SENSITIVITY ADJUSTMENT Steps Step Step Step 3 Function Determine Position A Determine Position B Adjust to optimum setting Sensing Condition Photoelectric sensor Photoelectric sensor Photoelectric sensor Sensing object Sensing object Sensing object Sensitivity adjuster A B A B Min Max Min Max Min Max Indicators OFF ON OFF OFF ON OFF STABILITY (green) LIGHT (red) STABILITY (green) LIGHT (red) STABILITY (green) LIGHT (red) 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. 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 0 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 -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 cm (.8 in), making it easy to check the sensing position and the angle of the optical axis.. 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.. Press the OFF-delay time adjuster to switch ON the turbo function with a maximum force of 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 Sensitivity adjuster The OFF-delay time adjuster is used as a turbo switch (black) Visible spot PUSH Normal Operating Condition

16 Self-Diagnostic Function With this function, the 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 signal.

EXTERNAL DIAGNOSTIC INPUT FUNCTION To switch the emission off, short- the gray (pink) and the black (blue) cords of the emitter of the T or the R with the NPN feature. For the R with the PNP feature, short- the gray (pink) and the red (brown) cords. NOTE: IEC colors are shown in parentheses.

17 SLITS FOR THROUGH-BEAM SENSORS E39-S6 Slit Set Using slits allows smaller objects to be detected and reduces the sensing distance. Slit width Sensing distance Min. object size 0. mm 0. m (.6 ft) 0. mm (0.0 in) mm. m (3.6 ft) mm (0.0 in) mm. m (8. ft) mm (0.08 in) Use the rubber attachment with the metal cover if a slit width of mm is required. Insert the 0.- or -mm slit between the metal cover and rubber attachment if a slit width of 0. or mm is desired. These slits fit into the rubber attachment. mm Notches to hold cover Metal cover Slit (0. mm or mm) Rubber attachment Arrow indicating position of optical axis 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 CONFIRMATION REFLECTOR E39-R 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. Eye Emitter E39-R Receiver confirmation reflector ADJUSTER CAP AND OPTIONAL E39-G SENSITIVITY ADJUSTER KNOB Adjuster Cap (Supplied with each sensor) In order to prevent the sensitivity or OFF-delay time that has been set from changing accidentally, cover the adjusters with the adjuster cap (enclosed). Aduster cap E39-G Adjuster Knob To temporarily use the knob to adjust the sensitivity of the photoelectric sensor, insert side A into the shaft of the sensitivity adjuster. To snap the adjuster onto the sensor, push side B onto the sensitivity knob. (A) Press the adjuster cap until this face touches the name plate on the sensor. Aduster (B) E39-E6 MUTUAL INTERFERENCE FILTER A set of filters are sold together for two through-beam models (for 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). Receiver Emitter Be aware of the direction of polarization.
