Omron E3X-MDA DATASHEET

Digital Fiber Sensor

E3X-MDA Series

Instruction Sheet

Thank you for selecting an OMRON product.This sheet primarily describes precautions required in installing and operating the product.

• The specialist who has the knowledge of electricity must treat.

• Please often read this manual, and use it correctly after it understands enough.

• Please keep this manual importantly to refer at any time.

Precautions for Safe Use

Please observe the following precautions for safe use of the product.

1)Do not use the Amplifier Unit in environments subject to flammable or explosive gases.

2)Do not use the Amplifier Unit in environments subject to exposure to water, oil, chemicals, etc.

3)Do not attempt to disassemble, repair, or modify the Amplifier Unit in any way.

4)Do not apply voltages or currents that exceed the rated ranges.

5)Wire the Amplifier Unit correctly, e.g., do not reverse the polarity of the power supply.

6)Connect the load correctly.

7)Do not short both ends of the load.

8)Do not use the Amplifier Unit if the case is damaged.

9)When disposing of the Amplifier Unit, treat it as industrial waste.

Precautions for Correct Use

Please observe the following precautions to prevent failure to operate, malfunction, or undesiable effects on product performance.

1)The optical fibers are made out of methacrylic resin. Do not use them in atmospheres where organic solvents are present.

2)Wire the Amplifier Unit separately from power supply or high-voltage lines. If the Amplifier Unit wiring is wired together with or placed in the same duct as high-power lines, inductive noise may cause operating errors or damage the Amplifier Unit.

3) Do not extend the cable to more than 100 m, and use a wire size of 0.3 mm

4)The Amplifier Unit is ready to operate 200 ms after the power supply is turned ON. If the Amplifier Unit and load are connected to power supplies separately, turn ON the power supply to the Amplifier Unit first.

5)Always keep the protective cover in place when using the Amplifier Unit.

6)Connector Short-circuit Protection (for Amplifier Units with Connectors)

To prevent electric shock or short-circuits, attach the protector seals provided

with E3X-CN-series Connectors to the sides of power supply connectors that are not being used.

7)Always turn OFF the power supply before connecting, separating, or adding Amplifier Units.

8)If the data is not written to the EEPROM correctly due to a power failure or static-electric noise, initialize the settings using the keys on the Amplifier Unit.

9) Using a Mobile Console

Use the E3X-MC11-SV2 Mobile Console for the E3X-DA-S series Amplifier

Units. However, there is a function which cannot be used in part. Other Mobile Consoles, such as the E3X-MC11, cannot be used.

10) Optical communications are not possible with an E3X-DA-N Amplifier Unit.

11) Depending on the application environment, time may be required for the incident light level to stabilize after the power supply is turned ON.

12) Do not use thinners, benzine, acetone, or kerosene for cleaning the Amplifier Unit.

13) Do not pull or apply excessive pressure or force (exceeding 9.8 N・m) on the Fiber Unit when it is mounted to

the Amplifier Unit.

14) Output pulses may occur when the power is interrupted and so turn OFF the power to the load or load line before turning OFF the power to the Sensor.

DON (dark-ON)

The output will turn ON when the incident light level is above the threshold.

The output will turn ON when the incident light level is below the threshold.

2. Adjusting the Power (as Required)

Power tuning can be used to adjust the incident light level that is currently being received to the power tuning target value (default: 2,000). Before tuning ON the power, always secure the detection object and Head and be sure that the incident light level is stable.

■ Setting Method

③Teaching for Through-beam Sensor Heads

Teaching for a Through-beam Sensor Head is performed without a workpiece. A value about 6% less than the incident light level with no workpiece is set as the threshold value. This method is ideal to stably detect very small differences in light level.

Setting

Switch to RUN mode.

Display

If the output setting is set to 1-2 (differential operation), the differential value when teaching is performed is used as the threshold setting for channel 2.

(Same as for Teaching for Reflective Sensor Heads.)

④ Teaching for Reflective Sensor Heads

Teaching for a Reflective Sensor Head is performed without a workpiece (i.e., for the background). A value about 6% greater than the incident light level is set as the threshold value. This method is ideal to stably detect very small differences in light level.

Setting

Switch to RUN mode.

Display

If the output setting is set to 1-2 (differential operation), the differential value when teaching is performed is used as the threshold setting for channel 2.
