Up to 30 Amplifier Units can be connected to
E3NW Series Communication Unit.
Under environments such as vibration, use an End Plate
even with a single 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.
■
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.
Slide the Amplifier Unit until the communication connector is
closely attached.(Arrow 3)
(2)
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)
(3)
Tighten the screw on the End Plates using a driver.(Arrow 5)
Open the protection cover.
Insert the sensor head, with the lock lever on
its connector area facing upward, all the way
into the connector port.
The color of the connector cover for E3NC-SH is white.
Make sure to avoid misconnection by confirming
the cover color in advance.
To remove it, press and hold the lock lever
then pull the sensor head out.
Fix the sensor head with M3 screws.
Apply tightening torque of 0.5N·m for fixing.

・
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.

PRECAUTIONS FOR SAFE USE
PRECAUTIONS FOR CORRECT 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.
· 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. Use caution when operating or cleaning the
product.
· 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 miswire such as the polarity of the power supply.
· Be sure to mount the unit to the DIN track until it clicks.
· To prevent electric shock or short circuit, put a protection cap on unused connection power supply
terminals.
· Do not apply excessive force (9.8N max.) 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 Mobile Console E3X-MC11, E3X-MC11-SV2 and E3X-MC11-S cannot be connected.
· The mutual interference prevention function does not work when in combination with E3C/E2C/E3X.
· 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.
· Sensor communication unit E3NW can be used. E3X-DRT21-S and E3X-CRT/ECT cannot be 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.
· Do not use thinner, benzine, acetone, and lamp oil for cleaning.
