Operation J CHOOSING THE RIGHT TEACHING METHOD Refer to the following table to select the most suitable sensitivity setting method. Teaching method Maximum sensitivity setting No-object teaching With/Without-object teaching Typical application Detection of the existence of objects that interrupt light perfectly If teaching is impossible by stopping the movement of sensing objects Detection of a slight difference in reflection Detection of objects with no background objects Color discrimination To detect bright or dark objects Background objects with by teaching only with background unstable reflection objects Detection of object surface irregularities Elimination of background object influence Note: 1. None of the four channels has any output when the E3X-NM (four channels) is in teaching mode (i.e., all the four channels will be in teaching mode). 2. If the set distance is very short (i.e., 0 to 12 mm for the E32-TC200 and 0 to 4 mm for the E32-DC200), no-object teaching is not possible due to excessive light, in which case, perform with/without-object teaching. 3. In principle, use the E3X-NM (four channels) for the close connection of a maximum of four Fiber Units. When closely connecting two to three Fiber Units to more than one E3X-NT (one channel), perform with/without-object teaching, in which case teaching must be performed on a single E3X-NT at a time. Therefore, turn on only the E3X-NT on which teaching is performed. If all the E3X-NTs are turned on, interrupt the emitters of the Fiber Units on which teaching is not performed. 5 E3X-N E3X-N J MAXIMUM SENSITIVITY SETTING Note: The sensitivity of the E3X-NT and E3X-NM are set to maximum before shipping. When resetting the sensitivity of the E3X-NT or E3X-NM to maximum after no-object teaching or with/without-object teaching, follow the steps described below. Procedure Operation 1 Locate the sensor head within the rated sensing range with the E3X-Nj. E3X-NT 2 Set the mode selector to TEACH. 3 The flashing function of the E3X-Nj will be activated. Therefore, adjust the optical axes so that the tip of the emitting fiber will be lit. If the optical axes are divergent, the tip of the emitting fiber will flash and the built-in buzzer of the E3X-Nj will beep. 4 Press the teaching button for three seconds minimum with or without a sensing object. In the case of the E3X-NM, select a channel with the channel selector, at which time the stability indicator for the selected channel will flash. E3X-NM TEACH RUN TEACH TIMER SET RUN --- TEACH TEACH The teaching indicator (red) turns green. The built-in buzzer beeps once when the color of the teaching indicator is red. The built-in buzzer beeps continuously when the color of the teaching indicator is green. Note: The built-in buzzer will stop beeping when the teaching button is no longer being pressed. 5 Set the mode selector to RUN to complete the sensitivity setting. TEACH The teaching indicator is OFF. Note: When the sensitivity is set to maximum, the sensitivity will be automatically adjusted regardless of the set distances of the fibers or light. 6 Select the logical output required with the operation mode selector.

Therefore, adjust the optical axes so that the tip of the emitting fiber will be lit. If the optical axes are divergent, the tip of the emitting fiber will flash and the built-in buzzer of the E3X-Nj will beep. 4 Locate a sensing target in the sensing area and press the teaching button once. In the case of the E3X-NM, select a channel with the channel selector and press the teaching button, at which time the stability indicator for the selected channel will flash. E3X-NM TEACH RUN Through-beam Model Reflective Model TEACH TIMER SET RUN --- TEACH TEACH Reflective Model Mark Light is interrupted. Base The teaching indicator (red) is lit. The built-in buzzer beeps once. 5 Move the object and press the teaching button. Through-beam Model Reflective Model Reflective Model TEACH TEACH Mark Light is received. Base If teaching is OK: The teaching indicator (red) turns green. If teaching is NG: The teaching indicator (red) starts flashing. The built-in buzzer beeps once. The operation indicator also starts flashing. (E3X-NM) The built-in buzzer beeps 3 times. Change the position of the object and the sensing distance that have been set and repeat from the beginning. 6 Set the mode selector to RUN to complete the sensitivity setting. TEACH The teaching indicator (green) is OFF. RUN 7 Select the logical output required with the operation mode selector. L ON D ON Note: 1. Even if the E3X-Nj is turned off, the E3X-Nj will retain the sensitivity set at the time of teaching. 2. Channels (E3X-NM) are selected in the following order. When all the channels are selected, it is possible to set the sensitivity of the E3X-NM on all channels. 1 CH 2 CH 3 CH 4 CH ALL 7 TEACH TIMER SET RUN CH 1 L ON D ON 2 3 4 E3X-N E3X-N J NO-OBJECT TEACHING Procedure Operation 1 Locate the sensor head within the rated sensing range with the E3X-Nj. E3X-NT 2 Set the mode selector to TEACH. 3 The flashing function of the E3X-Nj will be activated. Therefore, adjust the optical axes so that the tip of the emitting fiber will be lit. If the optical axes are divergent, the tip of the emitting fiber will flash and the built-in buzzer of the E3X-Nj will beep. 4 Press the teaching button for 0.5 to 2.5 seconds without a sensing object. In the case the E3X-NM, select a channel with the channel selector and press the teaching button, at which time the stability indicator for the selected channel will flash. E3X-NM TEACH RUN TEACH TIMER SET RUN --- TEACH TEACH The teaching indicator (red) is lit. The built-in buzzer beeps once. 5 6 Set the mode selector to RUN. No-object teaching will be set when the first sensing object passes through the sensing area. TEACH The teaching indicator (red) turns green (automatically turned off in one second). RUN Select the logical output required with the operation mode selector. L ON D ON TEACH TIMER SET RUN CH 1 L ON D ON 2 3 4 Note: 1. To detect dark objects in front of bright backgrounds, set the operation mode selector to D. ON. 2. If the set distance is very short (i.e., 0 to 12 mm for the E32-TC200 and 0 to 4 mm for the E32-DC200), no-object teaching is not possible due to excessive light, in which case, perform with/without-object teaching. 3. If the teaching button is pressed for more than three seconds, the sensitivity of the E3X-Nj will be set to maximum, at which time the green indicator will be lit. 4. The E3X-Nj will be ready to detect objects in approximately one second after the mode selector is set to RUN. J SENSITIVITY ADJUSTMENT Combination of the E3X-NT/E3X-NM and Fine Through-beam Fiber Units (E32-T22S/T24S/T84S) No-object Teaching Press the teaching button once with no object in the sensing area. Object Note: If detection is not stable after no-object teaching, perform with/without-object teaching. With/Without-object Teaching Press the teaching button once with no object in the sensing area. 8 E3X-N E3X-N NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.
