Applications

Dependably Detects Marks on Laminated Sheets

The coaxial optical system ensures a long sensing distance and stable sensing characteristics over a wide angle range, even for objects that are distance-fluctuating or leaning at an angle, or for laminated objects with marks, which conventional models have difficulty in detecting

Auto-Teaching

An auto-teaching function automatically sets the threshold value upon a Remote Control input while the workpiece is moving.

There is no need to position the mark at the optical spot.

Adjustments

Adjustment Steps

1. Install, wire, and turn ON the Photomicrosensor.
2. Perform teaching (mark registration). Refer to Mark Registration (Teaching).

Mark Registration (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-point 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.

Refer to the following for each teaching method. Remote one- or two-point teaching is possible. Refer to Remote Control Function.

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.

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.

1. Make fine adjustments of the threshold level if necessary. Refer to Threshold Level Adjustments on page A-139.
2. Check that the mode selector is set to RUN.

Two-point Teaching

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.

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 indicator flash.

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.

Auto-teaching

1. Check that the mode selector is set to either RUN or ADJUST.
2. Input a 0.9-s pulse signal into the remote control I/O terminal. ^1
3. 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.

Example of Connection to Programmable Controller

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.

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 (Bank Selection, Mark Registration, and Threshold Adjustments) on page A-140.

Detection Level Indicator

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.

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.

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

Note: If Signals are sent continuously, make sure that there is an interval of 2.5 s between signal inputs as shown above.

Precautions

Observe the following precautions to ensure safety.

• 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.

Correct Use

Installation

Power Reset Time

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.

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. 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 100m provided that the thickness of the cable is 0.3mm2 minimum.

Repeated Cable Bending

The cable must not be bent repeatedly.

High-tension Lines

The power supply lines of the Sensor must not be wired alongside power lines or high-tension lines in the same conduit, otherwise the Sensor may become damaged or malfunction due to induction noise that may be generated from the power lines or high-tension lines.

Route the lines separately or in a single conduit.

Cable Pulling Force

Do not pull cables with pulling forces exceeding 50N.

Mounting

Screw Tightening

Make sure that the casing is tightened to a maximum torque of 1.2 N o m.

Mounting Direction

When Sensors are mounted to face each other, make sure to adjust the optical axes so that the Sensors will not be mutually interfered.

Others

EEPROM Write Error

An EEPROM error may result if power supply to the Sensor fails or the Sensor is influenced by static noise, in which case the threshold level indicators will flash. Perform the teaching and threshold level setting of the E3M-V again.

M12 Metal Connector

Make sure to connect or disconnect the metal connector after turning off the E3M-V.

Make sure to hold the connector cover when connecting or disconnecting the metal connector.

Tighten the metal connector securely by hand. 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.
