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 explo-
sive gas is present.
2. Do not use the product in locations subject to splashing water,
oil, or chemicals, or in locations subject to steam.

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

ditions. 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 ex-
ceed product ratings.
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 sep-
arately) cannot be used.
If an excessive amount of light is received via the Sensor, the mu-
tual 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-series
Amplifiers are gang-mounted without other E3X-series Amplifi-
ers.
Mounting
DIN Track Mounting/Removal
Mounting 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 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.)

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 Connection and Disconnection
The E3X Amplifier Unit has a lock lever. Connect or disconnect
the fibers to or from the E3X Amplifier Unit using the following pro-
cedures:
1. Connection
Open the Protective Cover, insert the fibers according to the fiber
insertion marks on the side of the Amplifier Unit, and lower the
lock lever.
2. Disconnection
Remove the Protective Cover and raise the lock lever to pull out
the fiber.
Note: To maintain the fiber properties, confirm that the lock is released
before removing the fiber.
3. Precautions for Fiber Connection/Disconnection
Be sure to lock or unlock the lock lever within an ambient temper-
ature range between 10C and 40C.
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.
Amplifier Units with Connectors
Mounting
Mounting Connectors
1. Insert the Master or Slave Connector into the Amplifier Unit un-
til 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 re-
move Connectors without separating them from other Amplifi-
er Units first.)
Mounting End Plate (PFP-M)
Depending on how it is mounted, an Amplifier Unit may move dur-
ing 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 under-
neath the clip.
1. Insert the clip to be removed into the slit underneath the clip on
another Amplifier Unit.
2. Remove the clip by rotating the Amplifier Unit.

Operating Procedure
Sensitivity Setting
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.
Teaching with/without a Workpiece
Two points (one with the workpiece and the other without) are de-
tected, and the operating level is set to the midpoint.
Light level is also automatically set to the optimal value.
Automatic Teaching
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 inci-
dent light level is not automatically set to the optimal value.
