Teaching Optical Fiber Photoelectric Sensor E3X-NV/NVG
AWater-resistant Sensor with aGreen
Light Source Ideal for the Food and
Packaging Industries
The E3X-NVG uses agreen light source to detect
colors that cannot be detected using optical fiber
photoelectric sensors with red light sources. (The
E3X-NV incorporates ared light source.)
Teaching without aworkpiece is possible, greatly
reducing sensor adjustment effort with no interrup-
tion of mark detection.
Resists water.
Remote teaching function for easy remote teaching
from the controller.

With/Without-object Teaching, No-object Teaching, Maximum Sensitivity Setting
Refer to the following table to select the most suitable sensitivity setting method.
Sensitivity setting method Maximum sensitivity setting No-object teaching With/Without-object teaching
Typical application Detection of the existence of
objects that interrupt light
perfectly
Detection of objects with no
background objects
If teaching is impossible by
stopping the movement of
sensing objects
Todetect bright or dark objects
by teaching only with background
objects
Detection of aslight difference in
reflection
Color discrimination
Background objects with
unstable reflection
Detection of object surface
irregularities
Elimination of background object influence
Note: 1. If the set distance is very short (i.e., 0to 12 mm for the E32-TC200 and 0 to 4mm for the E32-DC200), no-object teaching is not
possible due to excessive light, in which case, perform with/without-object teaching.
2. When closely connecting two to three Fiber Units to more than one E3X-NV/NVG, perform with/without-object teaching, in which
case teaching must be performed on a single E3X-NV/NVG at atime. Therefore, turn on only the E3X-NV/NVG on which teaching is
performed. If all the E3X-NV/NVGs are turned on, interrupt the emitters of the Fiber Units on which teaching is not performed.

ing object and the light without sensing object.
Resetting
Operating level
Light
Note: 1. After no-object teaching, when the E3X-NVjis turned offand on, the operation level will be set to the +10% of the initial light level
(refer to the above (1)) in reflective operation and 10% of the initial light level in through-beam operation and stand by.
2. After performing no-object teaching and changing to RUN mode, until the first sensing object is in the sensing area, the control
output will be prohibited (OFF). The control output will be determined when the first sensing object is detected.
3. The initial operating level compensation function will operate after teaching and/or after the E3X-NVjis turned on.
4. During no-object teaching, after the E3X-NVjis in RUN mode, the E3X-NVjrequires approximately 60 ms to determine the oper-
ating level from the time the first sensing object is in the sensing area. After the operating level is determined, the E3X-NVjwill
operate with anormal response speed of 500 ms.
Remote Teaching Function
Remote Teaching Function
In principle, the remote teaching function of the E3X-NVjshould be used for initial teaching. Basically,the method of remote teaching is the
same as that of sensitivity setting. In remote teaching, instead of pressing the teaching button, teaching is performed with aremote teaching
input signal.
1. Set the mode selector to RUN.
2. The following signal conditions must be given as remote teaching input conditions.
1. If remote teaching is not performed, cut the pink wire at the base
or connect the pink wire to the +V terminal.
2. After remote teaching input setting is finished, the E3X-NVjwill
be ready to detect objects in approximately one second.

Optical Axis Adjustment (Super-flashing Function)
Set the mode selector of the E3X-NVjto TEACH. The super flashing function of E3X-NVjwill be activated. When the optical axes of the fiber
heads are divergent and the light value decreases by approximately 10% of the maximum value, the tip of the emitting fiber will start flashing and
the built-in buzzer will beep. At this time, if the optical axes are divergent, adjust the axes. The peak light value will be memorized by the E3X-
NVj.Do not press the teaching button before or while adjusting the optical axes, otherwise, the super-flashing function will not operate.

Precautions
WARNING
The voltage supplied to the E3X-NV/NVG must be within the rated
voltage range. If avoltage exceeding the rated upper limit is im-
posed on the E3X-NV/NVG, the E3X-NV/NVG may explode or
burn.
Connect each power line of the E3X-NV/NVG correctly,otherwise
the E3X-NV/NVG may explode or burn.
Do not short-circuit the load connected to the E3X-NV/NVG, other-
wise the E3X-NV/NVG may explode or burn.
Caution
Fiber Unit
Fiber Connection and Disconnection
The E3X-NVjAmplifier has apush lock. Connect or disconnect the
fibers to or from the E3X-NVjAmplifier using the following proce-
dures:
1. Connection
Locked Unlocked
After inserting the fiber into the Unit, push down the lock lever to se-
cure the fiber.
After cutting the fibers with the Fiber Cutter (E39-F4), place an in-
sertion mark on the fiber so that it can be properly inserted into the
Amplifier.Insert the fiber into the Amplifier up to this insertion mark.
2. Disconnection
Push up the lock lever so that the fiber can be pulled out. In order not
to damage the fiber,make sure that the fiber is unlocked before pull-
ing out the fiber.
3. The fiber must be locked or released in atemperature range of
10°° to 40°°C.

Mounting
1. Mount the front part on the mounting bracket (sold together)
or aDIN track.
2. Press the back part onto the mounting bracket or the DIN
track.
Note: Do not mount the back part onto the mounting bracket or
the DIN track first and then mount the front part on the
mounting bracket or the DIN track, or the mounting strength
of the Amplifier Unit may decrease.

In the case of side mounting, attach the mounting bracket on the
Amplifier first, and secure the Amplifier with M3 screws and wash-
ers. The diameter of the washers should be 6 mm max.
Washers
(6 dia. max.)
Pull back the gray rail on the rear bottom with aflat-blade screwdriv-
er so that the Amplifier can be dismounted with ease.
Turning Power On
After the E3X-NVjis turned on, the E3X-NVjwill be ready to oper-
ate in 100 ms maximum. If power is supplied to the E3X-NVjand
the load is connected to the E3X-NVjindependently,be sure to
turn on the power supply connected to the E3X-NVjfirst.
When the E3X-NVjis turned on or off, no control output will be ON,
even though the operation indicator of the E3X-NVjwill be lit for an
instant.
Mutual Interference Protection Function
When closely connecting two to three Fiber Units to more than one
E3X-NVj,perform with/without-object teaching, in which case
teaching must be performed on a single E3X-NVjat atime. There-
fore, turn on only the E3X-NVjon which teaching is performed. If
all the E3X-NVjare turned on, interrupt the emitters of the Fiber
Units on which teaching is not performed.
Power interruptions or noise caused by static electricity or other
causes can result in write errors during any part of the teaching pro-
cess from teaching initial operating levels without aworkpiece to fi-
nal compensations. These errors include buzzers, lighting of teach-
ing indicators, simultaneous flashing of red/green indicators, light-
ing of operation indicators, and lighting or flashing of stability indica-
tors. If any of these occur,re-input teaching using the teaching but-
ton on the Amplifier.
Unlike the case with teaching errors, if any memory error occurs,
red/green teaching indicators will flash simultaneously,and opera-
tion indicators and stability indicators will also flash.
Others
When power is off:
The moment power is turned off, the E3X-NVjcould output apulse
signal which could affect the operation of the devices connected to
it. This will happen more often if power is supplied to the E3X-NVj
from an external power supply,thus affecting the connected timer
and counter.Use abuilt-in power supply as much as possible to
avoid this.
In the case of the cord is extended, use awire with 0.3 mm2min. The
total length of the cord should be 100 mmax.
Power supply:
If astandard switching regulator is used as apower supply,the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, or otherwise the E3X-NVjcan malfunction, influenced
by the switching noise of the power supply.
The supplied voltage must be within the rated voltage range. Unreg-
ulated full- or half-wave rectifiers must not be used as power sup-
plies.
Do not lay wiring to the Optical Sensor together with power lines in
the same piping or ducts. Doing so will cause induction between the
lines, possibly resulting in faulty operation or destruction. Always
lay wiring to the Optical Sensor in separate or dedicated piping.
