Digital Fiber Amplifier
E3X-DA-N
Truly ultimate fiber amplifier
in pursuit of "user friendliness"
and "high performance"
UL991*
Features
Reducing power line wiring meaning
space is saved. New design for easier
maintenance.
The connector type that uses the wire-saving connector sup-
plies power to the single-conductor slave connectors via the
three-conductor master connector. Hence, the following three
has been made possible.
1. Wiring is much simpler.
2. Relay connectors are not required meaning that space is used
more efficiently and costs are reduced.
3. Simple inventory control because of no differentiation between
master and slave in the amplifier section.
Super digital display by use of the Auto
Power Control (APC) circuit
The incident level of LEDs used in sensors is prone to deteriorate
with time and as a result, detection becomes unstable.
Using the APC (auto power control) circuit for the first time as the
fiber sensor, the E3X-DA-N series has no digital value variations,
realizing severe detection.
This makes the E3X-DA-N ideal for applications where a high de-
gree of sensitivity is required, such as detecting crystal glass.

Power consumption reduced by 70%.
Power consumption has been
reduced up to about 70%
from 1800 mW to 600 mW. (If
the digital display is off)
The digital display can be changed to full-
OFF or Dark-ON during RUN.
Power consumption can be reduced by setting the display to Full-
OFF/Dark-ON in applications where the digital display is rarely
looked at during RUN.
(Can be set at the Mobile Console only)
Beeper-sized, new-generation Mobile Console

Remote setting/adjustment function
Incident level and threshold can be displayed simultaneously.
Simultaneous turning possible using group teaching.
Differences in incident light avoided by group zero-reset.
Sensor head flashing during Amplifier operation
Alternatively, the amplifier channel can be displayed.

Setting/teaching/fine adjustment can
be made at the fiber front-end.
The Mobile Console has enabled
setting and teaching at the fiber
front-end, which could only be
made at the amplifier. You can
perform major adjustments while
looking at the work position, etc.

While teaching had to be
performed for each Amplifier
separately, it can now be
performed for several Ampli-
fiers at once using the Mo-
bile Console.
The incident levels of sever-
al amplifiers can be batch-
reset to zero by the group
zero-reset. This feature is
useful for reducing differenc-
es between the amplifiers.
Group teaching
If the amplifier being operat-
ed is away from the sensor
head, the sensor head can be
flashed or the amplifier chan-
nel can be displayed.

@Area Sensing
Area sensing is possible using the threshold values
for channels 1 and 2.
· If channel 1 is set to L/ON, output turns ON when
the incident level is between the thresholds.
· If channel 1 is set to D/ON, output turns OFF
when the incident level is between the thresholds.
The result is output to control output 1.
(Control output 2 is always OFF.)

• The four types of teaching given below are available.
• Once setting is made, operation is performed in the preset status thereafter. When a teaching error occurs, the level indicators
flash in red. Restart setting from the beginning.
Maximum Sensitivity Setting
One-point without-object teaching
Note: If one-point teaching is not available because the difference in level is too
fine, try two-point teaching.
Operation Mode Selector
There is no operation mode selector for twin-output models.

Amplifier units
Design
Power ON
The sensor is ready to sense an object within 200 ms after turn-
ing the power ON. If the load and sensor are connected to differ-
ent power supplies, always turn on the sensor power first.
Mounting
Connection/removing of amplifier units
(Connection)
1. Install the units one by one to the DIN rail.
2. Slide one unit toward the other, match the clips at the front
ends, and then bring them together until they "click".
(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.)
Fitting of Mobile Console head
When fitting the Mobile Console head, a 20 mm or more clear-
ance is needed on the left side.
Use of Mobile Console
For the twin output type (E3X-DA##TW), up to 16 channels
(eight E3X-DA##TW units) can be set from the Mobile Con-
sole E3X-MC11. (Note that the operation mode and area de-
tection cannot be set.)
Adjustment
Mutual interference prevention function
The digital display value may vary due to the light from the
other sensor. In that case, low the sensitivity (raise the thresh-
old) to stabilize detection.
EEPROM Write Error
If a write error occurs (operation indicator starts flashing) due
to power-off, static electricity or other noise in the teaching
mode, perform teaching again.
Optical communication
When connecting the amplifier units, assemble them in close
contact. During operation, do not slide or dismantle the ampli-
fier units.
Hysteresis adjustment
The Mobile Console allows hysteresis adjustment, but note
that the unit may not operate properly if the hysteresis setting
is lower than the factory value.
Correct Use
Note:1 .When the amplifier units are connected to each other, the
operable ambient temperature changes depending on the
number of connected amplifier units. Check "Ratings/Per-
formance".
2 .Before connecting or removing the units, always switch
power off.

Amplifier Unit Connectors
Installation
Connector installation
1. Insert the Master or Slave Connector into the amplifier unit
until it clicks into place.
2. Link amplifier units to each other after the master and slave
Connectors have been inserted.
3. Apply the supplied seal to the non-connecting surface of the
master/slave connector.
Note: Apply seal to the grooved side.
Removing Connectors
1. Slide the slave amplifier unit (s) on which the connector
must be removed from the rest of the group.
2. After the amplifier unit (s) has been separated, press down
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, an amplifier unit may move dur-
ing operation. In this case, use an end plate.
Before installing an end plate, remove the clip from the master
amplifier unit using a nipper or similar tool.
The sensor bottom is also equipped with a 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.
When fitting the Mobile Console, set the end plate in the guide
as shown in the following figure.
Tensile stress for connectors (including cables)
E3X-CN11, E3X-CN21, E3X-CN22: 30 N max.
