Precaution on Safety
●Meanings of Signal Words
Indicates a potentially hazardous situation which, if not avoided,
CAUTION
May result in minor or moderate injury or in property damage.
●Alert statements in this Manual
CAUTION
Do not use it exceeding the rated voltage.
There is a possibility of failure and fire.
Do not connect sensor to AC power supply.
Risk of explosion.
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.
Precautions for Correct Use
1)Do not use the Amplifier Unit under the following conditions.
①In the place exposed to the direct sunlight.
②In the place where humidity is high and condensation may occur.
③In the place where corrosive gas exists.
④In 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,
Protector seal
separating, or adding Amplifier Units.

11)Do not pull or apply excessive pressure or force
connector
(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.

5. Installing the Amplifier 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.
6. Connecting the Fiber Unit
1. Open the protective cover
2. Press up the lock button.
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.
The output will turn ON when the incident light 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.
The output will turn ON when the incident light 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.

Tuning completed and previous display returns.
The power tuning target value can be changed. Refer to 8. Detailed Settings.
The light level might change when the detection method is changed.
In that case, execute the power tuning again after changing the detection method.
If SHS is set for the detection method, the power tuning target value will be not have effect
and the power will be set to the minimum value.

Power tuning Errors
An error has occurred if one of the following displays appears after the progress bar is displayed.
Over Error
Flashes twice
The incident light level is too low for the power tuning target value.
The power can be increased up to approximately 5 times the incident
light level without power tuning.
PTUN OVER
Flashes twice Bottom Error
The incident light level is too high for the power tuning target value.
The power can be decreased down to approximately 1/20th the incident light
level without power tuning.
