Safety Precautions
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 exceed the rated voltage.
Excess voltage may result in malfunction or
fire.
Do not use an AC power supply.
Using an AC power supply may result in
rupturing.
High-temperature environments may result in
burn injury.
The following precautions must be observed to ensure safety.
1. Do not use the product in locations where flammable or
explosive gas is present.
2. Do not use the product in locations subject to splashing
water, oil, or chemicals, or in locations subject to steam.
3. Do not attempt to disassemble, repair, or modify the
product.
4. Do not apply voltage or current in excess of the rated
ranges.
5. Do not use the product in atmospheres or environments
that exceed product ratings.
6. Do not wire the product incorrectly, such as using incorrect
power supply polarity.
7. Connect the load properly.
8. Do not short-circuit both ends of the load.
9. Do not use the product if the case is damaged.
10. When disposing of the product, dispose of it as industrial
waste.
11. Do not use the product in locations subject to direct
sunlight.
12. The surface temperature of the product may rise as a
result of the ambient temperature, power supply, or other
usage conditions. Use caution when performing
maintenance and washing. Failure to do so may result in
burn injury.
Do not use the product in atmospheres or environments that
exceed product ratings.
Fiber Amplifier Units
●Designing
Communications Hole
The hole on the side of the Amplifier Unit is a communications
hole for preventing mutual interference when Amplifier Units
are mounted side-by-side. The E3X-MC11 Mobile Console
(sold separately) cannot be used.
If an excessive amount of light is received via the Sensor, the
mutual interference prevention function may not work. In this
case, make the appropriate adjustments using the sensitivity
adjuster.
Mutual interference prevention is effective when E3X-SD/-
NA-series Amplifier Units are gang-mounted without other
E3X-series Amplifiers.
●Mounting
DIN Track Mounting/Removal
Mounting Fiber Amplifier Units
1. Mount the Amplifier Units one at a time onto the DIN track.
2. Slide the Amplifier Units together, line up the clips, and
press the Amplifier Units together until they click into place.
Removing Fiber Amplifier Units
Slide Amplifier Units away from each other, and remove from
the DIN track one at a time. (Do not attempt to remove
Amplifier Units from the DIN track without separating them
first.)
WARNING
Caution
Precautions for Safe Use
Precautions for Correct Use
Note 1. The specifications for ambient temperature will vary according to the
number of Amplifier Units used together. For details, refer to Ratings
and Specifications.
2. Always turn OFF the power supply before mounting or removing
Amplifier Units.

Fiber Unit Connection and Disconnection
The E3X Amplifier Unit has a lock lever. Connect or
disconnect the fiber units to or from the E3X Amplifier Unit
using the following procedures:
1. Connection
Open the Protective Cover, insert the fiber units according to
the fiber unit insertion marks on the side of the Amplifier Unit,
and lower the lock lever.
Note:
If one of the fibers from the Fiber Unit is labeled as the Emitter fiber, such as
with a Coaxial Sensor, insert that fiber into the Emitter section. Refer to
Dimensions for the Fiber Unit to see if there is an Emitter fiber label.
2. Disconnection
Remove the Protective Cover and raise the lock lever to pull
out the fiber unit.
Note:To maintain the fiber unit properties, confirm that the lock is
released before removing the fiber unit.
3. Precautions for Fiber Unit Connection/Disconnection
Be sure to lock or unlock the lock lever within an ambient
temperature range between −10°C and 40°C.
●Operating Environment
Ambient Conditions
If dust or dirt adhere to the hole for optical communications, it
may prevent normal communications. Be sure to remove any
dust or dirt before using the Units.
●Other
Protective Cover
Be sure to mount the Protective Cover before use.
Fiber Amplifier Unitts with Connectors
●Mounting
Mounting Connectors
1. Insert the Master or Slave Connector into the Amplifier Unit
until it clicks into place.
2. Join Amplifier Units together as required after all the Master
and Slave Connectors have been inserted.
3. Attach the stickers (provided as accessories) to the sides of
Master and Slave Connectors that are not connected to
other Connectors.
Note: Attach the stickers to the sides with grooves.
Removing Connectors
1. Slide the slave Amplifier Unit for which the Connector is to
be removed away from the rest of the group.
2. After the Amplifier Unit has been separated, press down on
the lever on the Connector and remove it. (Do not attempt
to remove Connectors without separating them from other
Amplifier Units first.)
Mounting End Plate (PFP-M)
Depending on how it is mounted, an Amplifier Unit may move
during operation. In this case, use an End Plate.
Before mounting an End Plate, remove the clip from the
master Amplifier Unit using a nipper or similar tool.
The clip can also be removed using the following mechanism,
which is incorporated in the construction of the section
underneath the clip.
1. Insert the clip to be removed into the slit underneath the clip
on another Amplifier Unitt.
2. Remove the clip by rotating the Amplifier Unit.

Nomenclature
Operating Procedure
E3X-SD
The sensitivity can be set with the UP and DOWN Keys similar
to using an adjuster knob. The sensitivity can also be easily
set by using the following two teaching functions.
Two points (one with the workpiece and the other without) are
detected, and the operating level is set to the midpoint.
Light level is also automatically set to the optimal value.
Changes within a time are detected, and the operating level is
set to the midpoint between the maximum and the minimum
values of the changes. This setting is optimal for when the
workpieces cannot be stopped. Execute automatic teaching
again if the incident light level is not automatically set to the
optimal value.
E3X-NA
A bar display (with four green and one red) showing excess
gain is provided in addition to the orange operation indicator.
Use these when adjusting the light axis and setting the
sensitivity at setup.
