Procedure Locate the sensing object at the
detection distance of the E3V3 and
turn the sensitivity adjustor
clockwise to increase the sensitivity
of the E3V3 until the orange
operation indicator is lit. The moment
the orange operation indicator is lit,
stop turning the sensitivity adjustor,
the position of which is point A.
Remove the sensing object and turn the
sensitivity adjustor clockwise until the
E3V3 detects the background object and
the orange operation indicator is lit. The
moment the orange operation indicator is
lit, stop turning the sensitivity adjustor, the
position of which is point B. Turn the
sensitivity adjustor counterclockwise to
decrease the sensitivity of the E3V3 until
the orange operation indicator is off. The
moment the orange operation indicator is
off, stop turning the sensitivity adjustor, the
position of which is point C.
If there is no background object, point C is
where the sensitivity adjustor is set to
maximum.
Set the sensitivity adjustor midway
between points A and C, where the
best sensitivity of the E3V3 for the
sensing object is ensured, and make
sure that the green stability indicator
is lit with and without the sensing
object at that position of the
sensitivity adjustor. If the green
stability is not lit, try another sensing
method.
Note: The rotation range of the sensitivity adjustor is 240°. Do not try to turn the sensitivity adjustor clockwise or counterclockwise
excessively, otherwise the sensitivity adjustor will break.

Precautions
POWER SUPPLY
The permissible voltage imposed on the E3V3 must be 24 VDC +
10%maximum(i.e.,26.4V). Makesurethatthevoltageimposedon
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
turnedon.If theE3V3andtheloadconnectedtotheE3V3eachuse
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
sameconduitorductaspowerlinesorhigh-voltagelines,thephoto-
electric sensor could be induced to malfunction, or even be dam-
aged,byelectrical noise. Eitherseparatethewiring,or useshielded
lines as input/output lines to the photoelectric sensor.
The cord connected to the E3V3 can be extended up to 100 m pro-
videdthatthediameterofeachwireofthecordis0.3mm2minimum.
WATER RESISTANCE
Do not use the E3V3 in water, in the rain, or outdoors.
MOUNTING
WhenmountingtheE3V3,donothittheE3V3withahammer,orthe
E3V3 will loose watertightness.
Use M3 screws to mount the E3V3.
