Remote controll input and answer-back output share the same signal line. [. . . ] · If teaching is unsuccessfull, all the red threshold level indicator flash. Green detection level indicators are ON. Sensor One-point Teaching 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. Mark Sensor Base Mark Push Teaching is OK Base Push All the red threshold level indicators will flash if there is no difference in incident. Red threshold indicators are ON. Teaching is NG 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. A-138 Standard Photoelectric Sensors Auto-teaching 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. 1 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. (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. · · Auto-teaching Teaching starts Teaching completes and detection starts Remote control input/ Answer-back output Auto-teaching Answer-back Time Incident Mark (shorter passing time): Output ON Optimal threshold level set Base: Output OFF Dummy sampling (1st mark) Sampling (5th mark) Time Threshold Level Adjustments Example of Connection to Programmable Controller Sensor Programmable Controller I/O Unit 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 (Bank Selection, Mark Registration, and Threshold Adjustments) on page A-140 . 1 Set the mode selector to ADJUST Select the upper or lower 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. The threshold level increases. Upper threshold limit Remote control I/O Output Input Note: Be sure to connect the E3M-V to the Programmable Controller as shown above. Precautions when Using Automatic Teaching Incorrect discrimination may be caused by automatic teaching in the following cases. Use one-point or two-point teaching in such cases. [. . . ] Do not use any tool, such as pliers, otherwise the metal connector may be damaged. If the metal connector is not tightened securely, the metal connector may be disconnected by vibration and the proper degree of protection of the E3M-V may not be maintained. 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 E3MV will be more likely to output a single pulse when the control power supply is turned OFF. Therefore, supply power to the timer or counter from the same power supply for the E3M-V. Power Supply Type No full-wave or half-wave rectified power supplies can be connected to the E3M-V. 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, otherwise the E3MV may malfunction due to the switching noise of the switching regulator. Wiring Cable The cable can be extended up to 100 m provided that the thickness of the cable is 0. 3 mm2 minimum. Repeated Cable Bending The cable must not be bent repeatedly. [. . . ]
