FIBER INSERTION
Make sure that the fiber is fully inserted in the amplifier. The
sensing distance may decrease if the fiber is not fully inserted.

CUTTING FIBER
Insert a fiber into the Fiber Cutter and determine the length of the
fiber to be cut.
Press down the Fiber Cutter in a single stroke to cut the fiber.
An insertion mark can be placed on the fiber to serve as a
reference when inserting the fiber into the amplifier. Use the
following procedure.
Confirm through the cutter hole that the fiber is inserted beyond
the insertion mark hole so that the insertion mark is properly
indicated, and then press firmly down on the cutter.

(1)
Insert the fiber into the amplifier up to the insertion mark. Proper
fiber performance will not be achieved unless the fiber is inserted
all the way to the insertion mark. (This method is applicable to
standard, 2.2-mm-dia. fibers only.)

The cutting holes cannot be used twice. If the same hole is used
twice, the cutting face of the fiber will be rough and the sensing
distance will be reduced. Always use a new hole.
Use either one of the two holes on the right (refer to the following
figure) to cut a thin fiber as follows:
1. An attachment is temporarily fitted to a thin fiber before ship-
ment.

2. Secure the attachment after adjusting the position of the thin
fiber in the direction indicated by the arrow.
3. Insert the fiber to be cut into the E39-F4.

Connection
Do not pull or press the fiber units. The fiber units have a
withstand force of 9.8 N or 29.4 N (pay utmost attention because
the fibers are thin).
Do not bend the fiber unit beyond the permissible bending radius.
Do not bend the edge of the fiber units (excluding the E32-TR
and E32-DR).

Excessive vibration can break the fiber head. Use the following
method to prevent fiber head breakage.
A one-turn loop can
absorb vibrations.

Bending Radius
E39-F11 Sleeve Bender
The bending radius of the stainless steel tube should be as large
as possible. The smaller the bending radius becomes, the shorter
the sensing distance will be.
Insert the tip of the stainless steel tube to the Sleeve Bender and
bend the stainless steel tube slowly along the curve of the Sleeve
Bender (refer to the figure).

E39-F32 Protective Spiral Tubes
Insert a fiber to the protective spiral tube from the head connector
side (screwed) of the tube.

tube
Push the fiber into the protective spiral tube. The tube should be
straight so that the fiber is not twisted when inserted. Then turn
the end cap of the spiral tube.

Use the attached saddle to secure the end cap of the protective
spiral tube. To secure the protective spiral tube at a position other
than the end cap, apply tape to the tube so that the portion
becomes thicker in diameter.

Each fiber unit should be as close as possible before they are
connected.
Sensing distance will be reduced by approximately 25% when
fibers are connected.
Only 2.2-mm-dia. fibers can be connected.
Precautions
AVOID DAMAGE TO THE E3X-DA
• Voltage must not exceed the rated voltage of the E3X-DA.
• When supplying power to the E3X-DA, make sure that the
polarity of the power is correct.
• Do not short-circuit the load connected to the E3X-DA.
• Do not impose 100 VAC or more on models that operate
with DC.
• Do not use the E3X-DA in environments where flammable or
explosive gas exists.
• Do not disassemble, repair or modify the E3X-DA.
• The E3X-DA has an enclosure rating of IP50; do not immerse
in water.
• Load must be connected to the E3X-DA.
INSTALLATION
Power Reset Time
• The E3X-DA is ready to sense objects 100 ms after the unit
is turned on.
• If power is supplied to the E3X-DA and the load
independently, make sure to turn ON the E3X-DA first.
• When the E3X-DA is turned ON or OFF, the operation indica-
tor will be illuminated for an instant, but no control output will
be turned ON.
Power Supply
• Do not connect the E3X-DA to a full-wave or half-wave
rectified power supply.
• When a standard switching power supply is used, the frame
ground (FG) and the ground (G) terminal must be grounded.
Otherwise, the E3X-DA may experience noise problem.
WIRING
Cable
• The cable can be extended up to 100 m provided the wire
thickness is at least 0.3 mm
2
.
• Do not pull cables with pulling force exceeding 50N.
Avoid Damage or Malfunction Due to Induction Noise
• Never run the E3X-DA cables in the same conduit with power
lines or high tension cables.
Mutual Interference Protection Function
• Perform two-point teaching if two or three fiber units are
closely mounted. Only apply power to the unit that is in
teaching operation or block the emitters of the fiber units that
are not in teaching mode.
FURTHER INFORMATION
Correcting an EEPROM Error
• An EEPROM error may result if power failure or static noise
occurs. In this case, repeat the whole teaching procedure.
