E3NC
Amplifier Units
This Amplifier Unit 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 Amplifier Unit with voltage in excess
of the rated voltage.
Excess voltage may result in malfunction or fire.
Never use the Amplifier Unit with an AC power supply.
Otherwise, explosion may result.
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 Amplifier Unit 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 steam
• Locations subjected to strong magnetic field or electric field
2. Do not use the Amplifier Unit in environments subject to flammable
or explosive gases.
3. Do not use the Amplifier Unit in any atmosphere or environment
th
at exceeds the ratings.
4. To secure the safety of operation and maintenance,
do not install
th
e Amplifier Unit close to high-voltage devices or power devices.
5. High-voltage lines and power lines must be wired separately from
the Amplifier Unit. Wiring them together or placing them in the
same duct may cause
induction, resulting in ma
lfunction or
d
amage.
6. Do not apply any load exceeding the ratings. Otherwise, dama
ge
o
r fire may result.
7. Do not short the load. Otherwise, damage or fire may result.
8. Connect the load correctly.
9. Do not miswire such as the polarity of the power supply.
10.To use this device as connecting with each other,
be sure to
connect with the same po
wer supply and turn ON th
e power
simultaneously. Using a separate power supply will influence the
fu
nctions when connecting the devices to use them.
11.Do not use the Amplifier Unit if the case is damaged.
12.Burn injury may occur. Th
e Amplifier Unit surface temperature
rises depending on a
pplication conditions,
such as the ambient
temperature and the power supply voltage. Attention must be paid
during operation or cleaning.
13.When setting the sensor, be sure to check safety such as
by
stopping the
equipment.
14.Be sure to turn off the power supply before connecting
or
disconnecting wires.
15.Do not attempt to disassemble, repair, or modify the Amplifier Unit
in any way.
16.When disposing of the Amplifier Unit, treat it as industrial waste.
17.Do not use the Sensor in water, rainfall, or outdoors.
18.UL Standard Certification (Applicable Models: E3NC-LA21/LA51/
SA21/SA51 Only)
Only the sensors with Enhanced UL Certification Mark are certified
by UL. They are intended to be supplied by a "C
lass 2 circuit".
When
used in United States and
Canada, Please use the same
Class 2 source for input and output.The overcurrent protection
current rating
is 2A max. They were evaluated as Open type an
d
shall b
e installed within a enclosure.
1. Be sure to mount the unit to the DIN track until it clicks.
2. When using the Amplifier Units with Wire-saving
Connectors,
attach the protective stickers (provided with E3X-CN-series
Con
nectors) on the unused power pins to prevent electrical shock
and short circuiting
.
When using the Amplifier U
nits with Connectors
for
Commu
nications Units, attach the protective caps (provided wi
th
E3NW-series Sensor Communications Unit).
3. Use an extension cable with a minimum thickness of 0.3 mm
2
and
less than 10 m long.
4. 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
5. Do not apply excessive force (9.8 N
max.) such as tension,
compression or torsion to the connector of the Sensor Head that
is fixed to the Amplifier
Unit.
6. Always keep the protective cover in place when using the Amplifier
Unit. Not doing so may cause malfunction.
7. It may take time until the received light intensity
and measured
value become stable immediately after the power is turned on
depending on use enviro
nment.
8. T
he product is ready to operate 200 ms after the pow
er supply is
turned ON.
9. T
he Mobile Console E3X-MC11, E3X-MC11-SV2 and E3X-MC11-
S cannot be connected.
10.The mutual interference prevention function does not work whe
n
in combi
nation with E3C/E2C/E3X.
11.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.
12.Standard models (E3NC-@A21/51/7/9)
The Sensor Communications Unit E3X-DRT21-S, E3X-CRT, E3X-
ECT and E3NW cannot be connected.
Model for Sensor Communications Unit (E3NC-@A0)
The Sensor Communications Unit E3NW can be connected.
E3X-DRT21-S, E3X-CRT, E3X-ECT cannot be connected.
13.If you notice an abnormal condition such as a strange odor,
extreme heating of the unit, or smoke immediately stop using
the
product, turn of
f the power, and consult your dealer.
14.Do not use thinner, benzene, acetone, and lamp oil for cleaning.
