E3V3 E3V3
Precautions
POWER SUPPLY
The permissible voltage imposed on the E3V3 must be 24 VDC +
10% maximum (i.e., 26.4 V). Make sure that thevoltage imposedon
the E3V3 is correct before turning the E3V3 on.
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, or otherwise the E3V3 may malfunction due to the
switching noise of the power supply.
OPERATION OF THE E3V3 WITH POWER
TURNED ON
The E3V3 is ready to detect objects within 100 ms after the E3V3 is
turned on. If the E3V3 and the load connectedto the E3V3 eachuse
an independent power supply, be sure to turn on the E3V3 first and
then the load.
CONNECTION
If the input/output lines of the photoelectric sensor are placed in the
same conduit orduct aspowerlinesorhigh-voltagelines, thephoto-
electric sensor could be induced to malfunction, or even be dam-
aged, by electrical noise. Either separate the wiring, oruseshielded
lines as input/output lines to the photoelectric sensor.
The cord connected to the E3V3 can be extended up to 100 m pro-
videdthatthediameterofeach wireof the cord is 0.3mm
2
minimum.
WATER RESISTANCE
Do not use the E3V3 in water, in the rain, or outdoors.
MOUNTING
Whenmounting the E3V3, do not hit the E3V3 with a hammer,or the
E3V3 will loose watertightness.
Use M3 screws to mount the E3V3.
Move the E3V3 up, down, left, and right to find the range where the
operatingindicator is lit orunlit. ThenlocatetheE3V3in thecenterof
the range, at which time make sure that the stability indicator is lit.
PRECAUTIONS WHEN USING THE E39-R3,
E39-RSA, OR E39-RSB REFLECTOR
Before applying adhesive tape to the reflector, make sure that the
reflector is free from oil or dust, or otherwise the adhesive tape will
not stick to the reflector properly.
Do not cut or scratch the reflector or the reflector will loose water-
tightness.
Do not press the reflector with a metal object or a nail, otherwise the
reflector will not function properly.
WARNING
The E3V3 is not a safety component for ensuring the safety of
people as defined in EC directive 91/368/EEC, or as covered
by separate European standards or by any other regulations
or standards.
