● Warning Indications
Indicates a potentially hazardous situation which, if not avoided,
will result in minor or moderate injury, or may result in serious injury
or death. Additionally there may be significant property damage.
PRECAUTIONS FOR SAFE USE
Checking the Package Content
The following precautions must be observed to ensure safe operation of the product. Doing so may cause
damage or fire.
· Do not install the product in the following locations.
(1) Locations subject to direct sunlight (2) Locations subject to condensation due to high humidity
(3) Locations subject to corrosive gas (4) Locations subject to vibration or mechanical shocks exceeding the rated values
(5) Locations subject to exposure to water, oil, chemicals (6) Locations subject to steam
(7) Locations subjected to strong magnetic field or electric field
· Do not use the product in environments subject to flammable or explosive gases.
· Do not use the product in any atmosphere or environment that exceeds the ratings.
·
To secure the safety of operation and maintenance, do not install the product close to high-voltage devices and power devices.
· High-Voltage lines and power lines must be wired separately from this product. Wiring them together or
placing them in the same duct may cause induction, resulting in malfunction or damage.
· Do not apply any load exceeding the ratings. Otherwise damage or fire may result.
· Do not short the load. Otherwise damage or fire may result.
· Connect the load correctly.
· Do not use the product if the case is damaged.
· Burn injury may occur. The product surface temperature rises depending on application conditions, such as the
ambient temperature and the power supply voltage. Attention must be paid during operation or cleaning.
· When setting the sensor, be sure to check safety such as by stopping the equipment.
· Be sure to turn off the power supply before connecting or disconnecting wires.
· Do not attempt to disassemble, repair, or modify the product in any way.
· When disposing of the product, treat it as industrial waste.
· Do not use the Sensor in water, rainfall, or outdoors.
· When joining the product, ensure to connect them to the same power supply and turn the power on at the same
time. The joined unit may not function fully if a separate power supply is used.
· If you notice an abnormal condition such as a strange odor, extreme heating of the unit, or smoke, immediately
stop using the product, turn off the power, and consult your dealer.
· Sensor heads other than E3C-LDA@@N are not usable. If other models are connected, there is a risk of damage.
INSTRUCTION SHEET
Thank you for selecting an OMRON product. This sheet
primarily describes precautions
required in installing and operating the product.
• A specialist who has the knowledge of electricity must
treat the product.
• Please read this manual carefully, and use it correctly
after thoroughly understanding the product.
• Please keep this manual properly for future reference
whenever it is necessary.
The following notice applies only to products that carry the CE mark:
NOTICE
In a residential environment, this product may cause radio interference,
in which case the user may be required to take adequate measures.
WARNING
WARNING
This product is not designed or rated for ensuring safety of persons
either directly or indirectly. Do not use it for such purpose.
Do not use the product with voltage in excess of the rated voltage.
Excess voltage may result in malfunction or fire.
Never use the product with an AC power supply. Otherwise,
explosion may result.
PRECAUTIONS FOR CORRECT USE
· Do not miswire such as the polarity of the power supply.
· Be sure to mount the unit to the DIN track until it clicks.
· When using a connector type product, place a protective label (provided with the
E3X-CN series) on the power supply connecting terminals that are not used, to
prevent electric shock or short circuit.
· The length for the cable extension must be 30 m or less.
Be sure to use a cable of at least 0.3 mm² for extension.
· Do not apply the forces on the cord exceeding the following limits:
Pull: 40 N; torque: 0.1 N·m; pressure: 20 N; bending: 29.4 N
· Do not apply excessive force such as tension, compression or torsion to the connector of the sensor head that is
fixed to the amplifier unit.
· Always keep the protective cover in place when using the product. Not doing so may cause malfunction.
· It may take time until the received light intensity and measured value become stable immediately after the
power is turned on depending on use environment.
· The product is ready to operate 300 ms after the power supply is turned ON.
· The Mobile Console E3X-MC11, E3X-MC11-SV2 and E3X-MC11-S cannot be connected.
· The mutual interference prevention function operates for E3C-LDA@@N. For other models, the product results
in mutual interference.
· Optical communication cannot be performed with a model other than E3C-LDA@@N. If other models are
connected and used, the product may malfunction.
· If the unit receives excessive sensor light, the mutual interference prevention function may not work properly,
resulting in malfunction of the unit. In such case, increase the threshold.
· The Communication Unit E3X-DRT21-S, E3X-CRT, E3X-ECT and E3NW cannot be connected.
· Do not use thinner, benzine, acetone, and lamp oil for cleaning.
· The amplifier unit uses EEPROM memory to save the configuration information. If the memory rewritable time
exceeds its limit (100,000 times), the memory error will be displayed and the amplifier unit needs to be
replaced. Memory data is rewritten, for each operation, three times when tuning, processing zero reset, and
changing the hysteresis width, and ten times when initializing the settings.
· If a crossed out wheelie bin symbol is labeled on the amplifier unit, dispose in accordance with
applicable regulations.

Up to 16 Amplifier Units can be joined. Under environments
such as vibration, use an End Plate even with a single amplifier
unit. If mounting the product without joining the amplifier unit,
seal the side optical communication part with lightproof tape.
• Do not touch the emitter and receiver areas of the
sensor head. A fingerprint may prevent proper
measurement.
If you accidentally touch it, use a soft cloth to wipe
it out.
• Fix the connector area so that it should not be
affected by oscillation and impact.
1. Mount the Amplifier Units one at a time onto the DIN track.
2. When using a wire-saving connector, mount the master
connector to A and slave connector to B.
3. Slide the Amplifier Unit until the Amplifier Unit is closely
attached.(Arrow 3) (For the wire-saving connector type, be sure
that a master connector and a slave connector, or a slave
connector and a slave connector are connected.)
4. Use End Plates (PFP-M: separately sold) at the both ends of the
grouped Amplifier Units to prevent them from separating due to
vibration or other cause.(Arrow 4)
5. Tighten the screw on the End Plates using a driver.(Arrow 5)
During or directly after the following operation, tuning cannot be executed.
Wait for a while before executing tuning.
Operation disabling tuning: tuning, setting initialization, emission OFF
For Output 2, light intensity is not adjusted during tuning. To adjust light intensity to the power tuning level, switch to Output 1. (Only the model with two-output type)

● Zero Reset Function
Returning Received Light Intensity Display to "0"
● DPC Function
For Stable Detection Regardless of Received Light Intensity Changed due to Dust or Dirt
When smart tuning is in error / output 1 is Area Detection Mode /
Detection Function is changed / power tuning adjustment
is turned OFF, the DPC function is disabled.
When the DPC function is disabled from the enabled state,
perform the tuning again or reset the threshold.
Use of the DPC function with regressive reflection model is recommended.
The zero reset is cancelled when smart tuning
is executed. Do not enable the DPC function
in the zero reset state.
● Area Detection Mode
For Output When Received Light Intensity is Within the Area
1. Select [Setting Mode] - [OUT1 Mode] -
[Area Detection Mode].
Pressing the [MODE] button for 3 seconds or longer
exits the [SET mode].
2. Press the [MODE] button in [Measurement Mode] to
display "OUT1 HIGH" and "OUT1 LOW".
Green digital indicator shows HIGH and LOW.
3. Provide Smart Tuning to each of HIGH/LOW
thresholds by pressing the [S.TUNE] button.
In tuning by percent, the thresholds are set as follows:
HIGH: Received light intensity in 3. + Received light intensity in 3. × Absolute value of percent tuning level
LOW: Received light intensity in 3. - Received light intensity in 3. × Absolute value of percent tuning level
Set HIGH/LOW thresholds HIGH > LOW.
The threshold also changes accordingly.
The lower threshold limit is -1999.
The DPC indicator turns ON
when the DPC function is effective.
