E3X-NA
A-373E3X-NA
Super Manual Fiber Amplifier
E3X-NA
Adjuster type standard that is the culmina-
tion of true ease and simplicity
Features
Instinctive LED bar displays of light levels
The previous manual type used the stability and incident level
indicators to display the light level change, which was difficult
to understand at a glance. The E3X-NA uses the LED bars to
display the light level, ensuring the light level change at a
glance.
Same "Wire-saving" Connector as
E3X-DA-N
OMRON's original wiring-saving connector, which was inher-
ited from the digital fiber amplifier E3X-DA-N, allows connec-
tion of up to 16 units.
* The vertical movement
of the LED light level
and operation display
shows the light level
at a glance.

Operation
Indicator status
In addition to the operation indicator (orange), E3X-NA has in-
dicators that denote the incident level (4 green and 1 red indi-
cators). Use them for optical axis adjustment and mainte-
nance.
Note: The rightmost indicator is turned ON at the "0 incident level".
Precautions
Amplifier Units
Design
Communications Hole
The window provided in the side face of the unit is a commu-
nication window for prevention of mutual interference when it
is connected with the other unit. Note that the optional Mobile
Console E3X-MC11 cannot be used. When the incident level
of the sensor is excessive, mutual interference prevention
may not be activated. At that time, make adjustment with the
sensitivity adjuster. When the unit is used with the E3X-DA-N
series, mutual interference prevention is not activated.
Mounting
Connection/removing of amplifier units
(Connection)
1. Install 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)
Slide one unit away from the other and remove them one by
one. (Do not remove the connected units together from the
DIN rail.)
Operating Environment
Ambient Conditions
Always remove dust, dirt, etc. from the optical communication
window, which may disable communication.

Correct Use
Note: 1 .When the amplifier units are interconnected, the operating ambient
temperature changes depending on the number of connected am-
plifier units. Check "Ratings/Performance".
2 .Before connecting or removing the units, always switch power off.

Installation
Installation 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. Apply the supplied seal to the non-connection surface of the
master/slave connector.
Note: Apply the seal to the grooved side.
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 the installation type, an Amplifier Unit may
move during operation. In this case, use an End Plate.
Before installing an End Plate, remove the clip from the mas-
ter Amplifier Unit using a nipper or similar tool.
The sensor bottom is also equipped with the clip removing
mechanism.
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.
