E3C-LDA@N
Amplifier Units
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
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 Safe Use
The following precautions must be observed to ensure safe operation
of the Amplifier Unit. Doing so may cause damage or fire.
1. Do not install the product in the following locations.
• Locations subject to direct sunlight
• Locations subject to condensation due to high humidity
• Locations subject to corrosive gas
• Locations subject to vibration or mechanical shocks exceeding
the rated values
• Locations subject to exposure to water, oil, chemicals
• Locations subject to stream
• Locations subjected to strong magnetic field or electric field
2. Do not use the product in environments subject to flammable or
explosive gases.
3. Do not use the product in any atmosphere or environment that
exceeds the ratings.
4. To secure the safety of operation and maintenance, do not install
the product close to high-voltage devices and power devices.
5. High-voltage lines and power lines must be wired separately from
the product. Wiring them together or placing them in the same duct
may cause induction, resulting in malfunction or damage.
6. Do not apply any load exceeding the ratings. Otherwise, damage
or fire may result.
7. Do not short the load. Otherwise, damage or fire may result.
8. Connect the load correctly.
9. To use this device as connecting with each other, be sure to
connect with the same power supply and turn ON the power
simultaneously. Using a separate power supply will influence the
functions when connecting the devices to use them.
10.Do not use the product if the case is damaged.
11.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.
12.When setting the sensor, be sure to check safety such as by
stopping the equipment.
13.Be sure to turn off the power supply before connecting or
disconnecting wires.
14.Do not attempt to disassemble, repair, or modify the product in any
way.
15.When disposing of the product, treat it as industrial waste.
16.Do not use the Sensor in water, rainfall, or outdoors.
17.If you notice any abnormal condition, immediately stop using the
product, turn off the power and consult your dealer without doing
any operation such as initialization.
18.Sensor heads other than those for E3C-LDA@@N cannot be used.
It may be damaged if connected.

WARNING
Precautions for Correct Use
1. Do not miswire such as the polarity of the power supply.
2. Be sure to mount the unit to the DIN track until it clicks.
3. 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.

Power Supply Connecting Terminal
4. The length for the cable extension must be 30 m or less. Be sure
to use a cable of at least 0.3 mm
5. 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
6. 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.
7. Always keep the protective cover in place when using the product.
Not doing so may cause malfunction.
8. 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.
9. The product is ready to operate 300 ms after the power supply is
turned ON.
10.The Mobile Console E3X-MC11, E3X-MC11-SV2 and
E3X-MC11-S cannot be connected.
11.The mutual interference prevention function works when between
E3C-LDAN. The mutual interference will occur if other amplifier
units are used.
12.Sensor heads other than those for E3C-LDAN cannot be used. It
may be damaged if connected.
13.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.
14.The Communication Unit E3X-DRT21-S, E3X-CRT, E3X-ECT and
E3NW cannot be connected.
15.Do not use thinner, benzine, acetone, and lamp oil for cleaning.
16.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.
17.
If a crossed out wheelie bin symbol is labeled on the
amplifier unit, dispose in accordance with applicable
regulations.
