Never use the product with an AC power supply. Otherwise, explosion may result.|

PRECAUTIONS FOR SAFE USE

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-LDAN are not usable. If other models are connected, there is a risk of damage.

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-LDAN. For other models, the product results in mutual interference.

• Optical communication cannot be performed with a model other than E3C-LDAN. 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.

Input / Output Circuit Diagram

Mounting the Amplifier Unit

Mounting on DIN Track

1. Let the hook on the Amplifier Unit’s Sensor Head connection side catch the track.
2. Push the unit until the hook clicks into place.
   DIN track (PFP-N) is sold separately.

Removing from DIN Track

1. Push the unit in the direction 1.
2. Lift the unit in the direction of arrow 2 while performing step (1).

Joining Amplifier Units

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)
   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.

Mounting the sensor head

1. Open the protection cover.
2. Insert the sensor head, with the lock lever on its connector area facing upward, all the way into the connector port.
   To remove it, press and hold the lock lever then pull the sensor head out.

• 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.

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.

Returning Received Light Intensity Display to “0”
Zero Reset Function

The zero reset is cancelled when smart tuning is executed. Do not enable the DPC function in the zero reset state.

The threshold also changes accordingly.
The lower threshold limit is -1999.

For Stable Detection Regardless of Received Light Intensity Changed due to Dust or Dirt
DPC Function
Use of the DPC function with regressive reflection model is recommended.

Refer to ” Settings”.
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.
