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.
