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.

1. Ratings and Specifications

3. Basic Operating Information

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

1) 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.

2)

Do not extend the cable to more than 30 m, and use a wire size of 0.3 mm2 or larger for the extension cable.

3)

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.

Please turn on the power supply at the same time when you connecting use the Amplifier Units with cables.
Mutual interference prevention might not operate normally or mobile console might not be able to be used

when the difference between connected Amplifiers at the power supply turning or time is 30ms or more.

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

5)

When using a connector model, place a protective label (provided with the E3X-CN series connectors) on

the power supply connecting terminals that are not used, to prevent electric shock or short circuit.

6)

When using a communication unit connection model, place a protective cap

(provided with the E3X-ECT/CRT communication unit ) on the connecting
terminals that are not used, to prevent electric shock or short circuit.

7) When connecting or removing the communication unit connection
model, make sure that the connecting part is not slanted.

8)

Always turn OFF the power supply before connecting or disconnecting Sensor

Heads, joining or separating Amplifier Units, or adding Amplifier Units.

9)

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.

10) Using a Mobile Console(The communication unit connection
model cannot use a mobile console.)
Use the E3X-MC11-SV2 Mobile Console for the E2C-EDA-series Amplifier Units. Other Mobile
Consoles, such as the E3X-MC11,E3X-MC11-S, cannot be used.

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

12)

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

13) 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.

14) The Sensor Head of E3C-LDA cannot be used. It may damage, if it connects.

15)

When mutual interference prevention is confirmed, the execution time of fine positioning becomes long.

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

17)

A disconnection output may be rarely outputted under the large installation conditions of a detection level also except disconnection.

Refer to 5.Detailed Settings Detection Method

Operation/Storage: 35 to 85 %RH (with no condensation)

10 to 55 Hz, 1.5mm double amplitude 2 hours each in X, Y, and Z directions

The mode is set using the SET/RUN switch. Set this switch according to the operation to be performed.

Teaching is performed in the state where a workpiece is in an ON
point. A detection level is set up as a threshold value.

Teaching is performed in the state where there is no workpiece.
It sets up about +6% of a detection level as a threshold value. It is stabilized and a very small
difference can be detected.

If DIFF(differential operation) is set for the detection method, the threshold value will be set
to the minimum value above the detection level without a workpiece that will enable stable
detection.

Teaching can be performed twice, once with and once without a workpiece, and the value between
the two measured values is set as the threshold.

In the case of a 【Method 2】, please check that a setup of a "MODE key setting" function is
[2PNT](teaching with and without a workpiece) in advance. Refer to 5.Detailed Settings.

The operation keys are used to switch the displays and set detection conditions. The functions of the
keys depend on the current mode.

The information displayed on the main display and sub-display depends on the current mode. For the
default settings, the RUN mode displays will appear when the power supply is turned ON for the first time.

Select either normally-open or normally-close operation.

Fine positioning can be used to adjust the detection level that is currently being received to the fine
positioning target value (1,500). Before executes fine positioning, always secure the workpiece and
Sensor Head and be sure that the detection level is stable.

Confirm that the MODE key setting is FP(fine positioning) in advance.
The default is "PPT" (positioning teaching). Refer to 5. Detailed Settings.

Teaching cannot be performed when DIFF(differential operation) is set as the detection
method.

4. Basic Settings

The output will turn ON when the detection level is above the threshold.
If DIFF (differential operation) is set for the detection method, the output will turn
ON when an edge is detected.

Set as the operation mode in SET mode.
Refer to 5. Detailed Settings.

Set using the operation mode selector.

The output will turn ON when the detection level is below the threshold.
If DIFF (differential operation) is set for the detection method, the output will turn
OFF when an edge is detected.
