Perform teaching (mark registration). Refer to Mark Registration (Teaching). Make fine adjustments of the threshold level if necessary. Refer to Threshold Level Adjustments. Check that the mode selector is set to RUN. Mark Registration (Teaching) Two-point Teaching Refer to the following for ideal teaching. Application The base has a color pattern. The mark and base are clearly different in color. The base has no color pattern. The mark and base are slightly different in color. The base has no color pattern. Remote teaching with no positioning is desired. One-point teaching Two-points teaching Auto-teaching The default level is set and the output is ON when the mark is detected. The threshold level is set between the color of the mark and base. The output is ON when the mark is detected. The threshold level is set between color of the mark and base. The output is ON when the mark (i.e., the color with shorter passing time) is detected. 1 Set the mode selector to TEACH. 2 Locate the mark to the sensing position and press the SET button. All the red threshold indicators will turn ON. Sensor Mark Base Red threshold indicators are ON. 3 If teaching is successful, move the mark and press the SET button at the base. * If teaching is successful, all the green detection level indicators are ON. * If teaching is unsuccessful, all the red threshold level indicators flash. Green detection level indicators are ON. Sensor Refer to the following for each teaching method. Remote one- or two-point teaching is possible. Refer to Remote Control Function. Mark One-point Teaching Base 1 Set the mode selector to TEACH. 2 Locate the mark to the sensing position and press the SET button. Then all the red threshold indicators are ON. Push Teaching is OK All the red threshold level indicators will flash if there is no difference in incident. Sensor Mark Base Push Teaching is NG Push Red threshold indicators are ON 3 Set the mode selector to RUN. The output will be ON whenever the set mark is detected. Note: By teaching on the base, reversed output as shown above (base: ON, mark: OFF) can be obtained. 4 If teaching is successful, set the mode selector to RUN to complete the teaching operation. If teaching is unsuccessful, restart from the above step 2. Note: Follow the above steps so that the output will be turned ON whenever the mark is detected. By taking the opposite steps, the output will be turned OFF whenever the mark is detected and turned ON whenever the base is detected. 8 E3M-V E3M-V J ADJUSTMENT STEPS Auto-teaching 1. 2. 3. * * Check that the mode selector is set to either RUN or ADJUST. Input a 0.9-s pulse signal into the remote control I/O terminal. (See Note.) Auto-teaching starts when the mark is moved. When the mark passes six times, auto-teaching completes. If teaching is successful, answer-back output from the remote control I/O terminal will turn ON for 0.3 s. If teaching is unsuccessful, no answer-back signal will be output. Readjust using two-point teaching. (Teaching will be unsuccessful if there is no difference in incident between the mark and base.) 4. If the answer-back signal is ON, the whole teaching operation will be completed. The output will be turned ON whenever the mark (i.e., the color with shorter passing time) is detected. Note: Make sure that the input tolerance of each pulse is within 0.1 s. Auto-teaching Illustration Remote control input/ Answer-back output Teaching completes and detection starts Teaching starts Auto-teaching Answer-back Time Mark (shorter passing time): Output ON Incident Optimal threshold level set Base: Output OFF Dummy sampling (1st mark) Example of Connection to Programmable Controller Programmable Controller Sensor Time Sampling (5th mark) 1 Set the mode selector to ADJUST. 2 Select the upper or lower threshold setting with the threshold selector. Whenever the SET button is pressed, the threshold level will move. Two indicators will be lit together when the threshold level is an even level. I/O Unit The threshold level increases. Remote control I/O Output Input Upper threshold limit Note: Be sure to connect the E3M-V to the Programmable Controller as shown above. Precautions when Using Automatic Teaching Press Incorrect discrimination may be caused by automatic teaching in the following cases. Use one-point or two-point teaching in such cases. * * * The threshold level decreases. Lower threshold limit Color patterns exist in the base. Sensing objects change their positions. Sensing objects have protrusions or surface level differences. Threshold Level Adjustments It is possible to make fine adjustments of the threshold level after teaching. Such fine adjustments can be made remotely as well. Refer to Remote Control Function. Threshold indicators Threshold level 3 9 After setting the level, set the mode selector to RUN. E3M-V E3M-V Detection Level Indicator The control output of the E3M-V will be turned ON if the detection level exceeds the threshold level. The indication of the detection level varies with the teaching method. One-point Teaching The upper and lower threshold values are set on the basis of the mark and the detection level indicators indicate the degree of color conformity to the mark's color. Detection level indicators Detection level Operation indicator Remote Control Function (Bank Selection, Mark Registration, and Threshold Adjustments) Under Run Mode or Adjust Mode The input of any of the signals listed in the following table into the remote control I/O terminal allows remote control of the E3M-V. When the signal is accepted, answer-back output will be turned ON for 0.3 s. Only in the case of one-point teaching, however, can the signal be manually input, provided that the input is ON for 1.5 s or more. Timing Chart Answer-back output: ON only when the process completes normally. Output OFF Threshold value 2.5 s min. Output ON Mark Remote control I/O Threshold value Output OFF Sensor operation Two-point or Auto-teaching A single threshold value is set between the mark (registered first) and the base (registered next). The detection level indicators indicate the tolerance between the mark and base.

Cable * * * * * * * * Do not use the Sensor in locations subject to flammable or explosive gases. Do not use the Sensor in water or conductive solution. Do not disassemble, repair, or modify the Sensor. Use the Sensor under proper power supply specifications such as the use of AC or DC power supply. Do not apply any voltage or current exceeding the rated level. Be careful with the power supply polarities and wire correctly. Connect the loads correctly. Do not short-circuit both ends of loads. * * * The cable can be extended up to 100 m provided that the thickness of the cable is 0.3 mm2 minimum. The cable must not be bent repeatedly. Do not pull cables with pulling forces exceeding 50N (11.24 lb). High-tension Lines To avoid damage and malfunctioning due to induction noise, wire sensor power lines in a separate conduit from any power lines or high tension lines. J MOUNTING J INSTALLATION AND USE Screw Tightening Power Reset Time Make sure that the casing is tightened to a maximum torque of 1.2 N S m. Since the E3M-V is ready to detect objects from 100 ms max. after the E3M-V is turned ON, operate the remaining devices 100 ms after the Sensor is turned ON. If power is supplied to the E3M-V and the load independently, be sure to turn on the E3M-V first. Mounting Direction When Sensors are mounted to face each other, make sure to adjust the optical axes to avoid mutual interference. J EEPROM WRITE ERROR Power OFF The E3M-V may output a single pulse when the control power supply is turned OFF. If the E3M-V is connected to a timer or counter to which power is supplied from an independent power supply, the E3M-V will be more likely to output a single pulse when the control power supply is turned OFF. For this reason, supply power to the timer or counter from the same power supply for the E3M-V. Power Supply Type An EEPROM error may result if power supply to the Sensor fails or the Sensor is influenced by static noise, and the threshold level indicators will flash. Perform the teaching and threshold level setting of the E3M-V again. J M12 METAL CONNECTOR * Supply voltage ripple must not exceed rated percentage. * Power Supply Connection Be sure to ground the FG (frame ground) and G (ground) terminals if a switching regulator is connected to the E3M-V to avoid malfunction due to the switching noise of the switching regulator. * * Turn off the E3M-V before connecting or disconnecting the metal connector. Make sure to hold the connector cover when connecting or disconnecting the metal connector. Tighten the metal connector securely by hand. To avoid damage, do not use any tool, such as pliers. If the metal connector is not tightened securely, it may be disconnected by vibration, and the proper degree of protection of the E3M-V may not be maintained.
