DISPLAY AND SPECIAL FUNCTION SETTINGS
Display Setting
The E3X-DA offers three display modes, which are Digital Incident Level display, Digital Percent display and Analog display.
•Digital Incident Level Display: the incident level is digitally displayed.
•Digital Percent Display: the threshold-based excess gain is displayed in percentage.
•Analog Display: threshold and excess gain is displayed by two-color (red and green) bar graph.
Special Function Setting
The E3X-DA series has various functions that give users more flexibility in meeting a variety of application requirements.
•Sensing Function: Enables users to choose either standard sensing distance mode (400 mm), long sensing distance mode
(500 mm) or high speed mode (response time = 250 s)
•Timer Function: Enables users to select various OFF-delay timer settings from (0 to 200 ms). OFF-delay timer lengthens the dura-
tion of a short, high-speed signal so that it can be recognized as input to Programmable Controllers during a scan cycle.
•Flashing Function: Flashing red LED allows easier optical axis adjustment.
•Display Hold Setting: This function provides easy data reading during optical axis adjustment and high-speed detection by holding
the displayed value for a period of time. Displayed data gets updated every 2 seconds. Within the 2-second timeframe, the maximum
or minimum value is displayed (data will be flashing).
•Display Orientation Setting: Reversible digital display provides easy data reading from any mounting orientation.

SPECIAL FUNCTION SETTING
E3X-DA series has various functions that give users more
flexibility in solving a variety of application requirements such as
the following:
•Long sensing distance (Sensing Function)
•Faster response time (Sensing Function)
•Off-delay timer (Timer Function)
•Optical axis alignment (Flashing Function)
•Digital data display hold setting (Display Hold Setting)
•Data display orientation (Display Orientation Setting)
Sensing Function
1. Set the mode selector to “SET”.
Mode

2. Press the “MODE” button until “fs t” is displayed. The “Stan-
dard” sensing function (fs t) is the default setting. The
“Standard” sensing function provides the standard detecting
distance (400 mm). Response time is 1 ms.
3. Press the “TEACH” button to obtain the “Long Distance”
sensing function. “F Ld” should appear on the display. The
“Long Distance” function provides a sensing distance that is
about 1.3 times that of the “Standard” detecting distance
(diffuse fiber in use). The “Long Distance” setting has a re-
sponse time of 4 ms.
4. Press the “TEACH” button to obtain the “High Speed” sens-
ing function. “F HS” Should appear on the display. The “High
Speed” function provides a detection distance that is about
one-third of the standard distance (diffuse fiber in use). Re-
sponse time is 0.25 ms.

Fiber Connection and Disconnection
The E3X amplifier has a lock button. Connect or disconnect the
fibers to or from the E3X amplifier using the following procedures:
1. Connection
Remove the protective cover, insert the fiber into the amplifier,
and lower the lock button until a click is heard.
Lock button
Fiber
Fiber insertion mark
After cutting the fiber using the E39-F4 Fiber Cutter, put an
insertion mark on the fiber as a guide for correct insertion into the
amplifier, and then insert the fiber up to this mark.
2. Disconnection
Remove the protective cover and raise the lock button to pull out
the fiber.
Protective cover

Note: Remove the protective cover and raise the lock lever to
pull out the fiber. (Before removing the fiber, be sure to
confirm that the lock is released so as to maintain the fiber
properties.)

Be sure to lock or unlock the lock button within an ambient
temperature range between –10°C and 40°C.

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.)
12.6 mm Insertion mark
2.2-mm dia.
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.

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 mm2.
•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.
