Precautions for Correct Use

Precautions for Safe Use

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)Do not use the Amplifier Unit in atmospheres or environments that exceedproduct ratings.

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

7)Connect the load correctly.

8)Do not short both ends of the load.

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

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

11)Do not use the sensor in the place exposed to the direct sunlight.

1)Do not use the Amplifier Unit under the following conditions.

In the place exposed to the direct sunlight.

In the place where humidity is high and condensation may occur.

In the place where corrosive gas exists.

In the place where vibration or shock is directly transmitted to the product.

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)For extending wires,use a cable 0.3mm min., and 100m max. in length.

When using the cable as a Korea’s S-mark certified product, use the cable of less than 10m 

in length.

4)Do not extend the follwing force values applied the cable.Tensile:40 N max.,torque:0.1 Nm 

   max.,pressure:20 N max.,flexure:3 kg max.

5)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.

6)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 on 

    time is 30ms or more.

7) Depending on the application environment, time may be required for the light level to 

    stabilize after the power supply is turned ON.

8)Output pulses may occur when the power is interrupted, so turn OFF the ower to the load or 

   load line before turning OFF the power to the Sensor.

9)When you use the 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.

10)Always turn OFF the power supply before connecting, 

separating, or adding Amplifier Units.

11)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.

 12) Mobile console E3X-MC11-SV2 doesn't correspond to the new feature such as tough mode 

     and ON delay OFF delay timer now. E3X-MC11-S cannot be used.

 13)Optical communication are not possible with the E3X-DA-N. 

     Optical communication are possible with the E3X-DA-S or the E3X-MDA.

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

 15)Do not use thinners, benzine, acetone, or kerosene for cleaning the 

Amplifier Unit.

3. Insert the fiber unit all the way to the back of the 

connector insertion opening.

4. Return the lock button to its original position 

to secure the fiber unit.

 Mounting Units

Catch the hook on the Fiber Unit connector end of the 

Unit on the DIN Track and then press down on the 

other end of the Unit until it locks into place.

Always attach the Fiber Unit connector end first. 

If the incorrect end is attached first, the mounting

strength will be reduced.

Removing Units

Press the Unit in the direction indicated by "1" 

and then lift up on the Fiber Unit connector end 

of the Unit in the direction indicated by "2."

Joining Amplifier Units (for Units with Connectors)

Up to 16 Units can be joined.

1. Mount the Amplifier Units one at a time onto the 

    DIN Track.

2. Slide the Amplifier Units together and press the 

    Amplifier Units together until they click into place.

Secure the Units with an End Plate (PFP-M) if 

there is a possibility of the Amplifier Units moving, 

e.g., due to vibration.

Remove the Units in the reverse order.
