Be sure to follow the safety precautions below for added
safety.
(1) Do not use the sensor under the environment with
explo-sive or ignition gas.
(2) Never disassemble, repair nor tamper with the product.
(3) Keep the supply voltage within the specified range.
(4) Do not use the sensor over the rated values.
(5) Do not short-circuit the load. The sensor type has a
load short-circuit protective function, but avoid
keeping it short-circuited for a long time.
(6) Do not use the sensor in the water.
(7) Be careful not to confuse the terminal polarities.
(1) Do not use the product under the following conditions.
In the place exposed to the direct sunlight.
In the place where humidity is high and condensa-
tion may occur.
In the place where corrosive gas exists.
In the place where vibration or shock is directly
transmitted to the product.
(2) Connections
Before turning on the power, make sure the supply
voltage is below the maximum voltage level.
Routing the wires of the photoelectric switch with
high potential power lines may cause malfunction or
damage to it because of the inductive effects.
Be sure to route the switch wires separated from the
power lines or though an exclusive conduit.
For extending wires, use a cable of 0.3mm
2
min. and
100m max. in length.
(3)Cleaning
Do not use thinner such as alcohol and benzine because it
may damage a product.
(4)Power supply
When using a commercially available switching regula-
tor, be sure to ground the FG (Frame Ground) and G
(Ground) terminals.If this is not done, failure in opera-
tion may happen by switching noise of the regulator.
(5)Function of this sensor will be stable 100ms after turning
on the power supply.
(6)Water-proof
Do not use in the water, rain or outdoor.
(7)Control cover
Tighten the cover screws at the torque of 0.2 to 0.3
N
・
m to keep water-proof.
(1) Position the photoelectric switch so that direct sunlight,
flourescent light, incandescent light and any other
strong rays do not come within the response angle.
(2) Sensors that are installed facing each other may cause
mutual interference. Set them up with their optical axes
not facing each other.
(3) Use 3M screws to secure the unit.
(4) Tighten the casing screws to 0.54 N-m or lower.
(5) Before connecting and disconnecting the connectors,
be sure to turn off the power.
(6) In connecting and disconnecting the connectors, be
sure to hold the connector covers.
(9) If there is something mirror-surfaced below the
photo-electric switch, the switch performance may be
adversely affected. Tilt the switch or keep it away
enough from the mirror surface.
(8) When detecting a glossy object, however, place the
photoelectric switch tilted 5–10
°
to the glossy object. See
the figure bellow or select Zone one-point teaching.
In placing the photoelectric switch, pay attention to the
moving direction of a detectable object. See the figure
below.
3 . Set the MODE selector to the RUN position.
4 . Using the RUN MODE selector, select L-ON or D-ON.
L-ON: Output is given by the background.
D-ON: Output is interrupted by the background.
2. Direct the sensor toward the background and hold
down the SET button. All the THRESHOLD indicators
(red) light up. Then release the SET button.
・
When the teaching is acceptable, all the DISTANCE
indicators (green) light up.
・
If the teaching is rejectable, all the THRESHOLD
in-dicators (red) start flashing. Re-arrange the sensor.
Repeat steps 2 to 3 again.
1. Set the NORMAL/ZONE selector to the ZONE posi-
tion.
Set the Mode Selector to TEACH.
Set the selector to RUN to complete the distance setting.
The following settings can also be made.
To set the sensor's distance differential to the maximum
distance, see "Maximum distance setting".
To set it to the minimum distance, see "Minimum distance
setting".
Note 1: Background distance.
In case of Normal one-point teaching and Zone
one-point teaching, the distance between the
sensor and background is more than Xmm.
Note 2: In case the setting distance is more than
150mm, the maximum detecting distance
de-pend on color of the object. Before using,
make sure if it works. (Type E3G-L3
□
)
Be also careful when a detectable object has quite
different colors or is made of different materials.
(7) Be sure to place the photoelectric switch so that
its sensing face be parallel with (not tilted against) a
detect-able object.

DISTANCE SETTING (TEACHING)
●
Zone one-point teaching
●
Normal one-point teaching
1 . Set the NORMAL/ZONE selector to the NORMAL
position.
2. Direct the sensor toward the background and hold down
the SET button.
・
All the THRESHOLD indicators (red) light up.
・
If the teaching is rejectable, all the THRESH
indicators (red) start flashing.
3 . zSet the MODE selector to the RUN position.
4 . Using the RUN MODE selector, select L-ON or D-ON.
L-ON: Output is given between the background and
the sensor.
D-ON: Output is interrupted between the background
and the sensor.
●
Minimum distance setting
1. Set the NORMAL/ZONE selector to the NORMAL
position.
2. Set the UP/DOWN selector to the DOWN (
▼
) position.
3. Hold down the SET button for 3 seconds or longer.
・
All the THRESHOLD indigators (red) light up.
To set the sensor's distance differential to the minimum
distance, take the following steps.
To set the sensor's distance to the maximum distance,
take the following steps.
4. Wait until all the DISTANCE indicators light up. Set
the MODE selector to the RUN position.
5. Using the RUN MODE selector, select L-ON or D-ON.
(Refer back to the normal one-point teaching.)
4. Wait until all the DISTANCE indicators (green) light
up. Set the MODE selector to the RUN position.
5. Using the RUN MODE selector, select L-ON or D-ON.
(Refer back to the normal one-point teaching.)
●
Normal two-point teaching
1.Set the NORMAL/ZONE selector to the NORMAL
position.
2.Direct the sensor toward a work and hold down the
SET button.
・
All the THRESHOLD indicators (red) light up.
3. Move the work. Direct the sensor toward the back-
ground and hold down the SET button.
・
When the teaching is acceptable, all the DISTANCE
indicators (green) light up.
・
If the teaching is rejectable, all the THRESHOLD
in-dicators (red) start flashing.
4. When the teaching is accepted, set the MODE selector
to the RUN position. If it is rejected, change the work
position and distance. Repeat the above steps 3 and 4.
5. Using the RUN MODE selector, select L-ON or D-ON.
After teaching, the threshold can be finely adjusted.
If detection is unstable by difference of color, adjust
threshould to make detection stable.
1. Set the MODE selector to the ADJ position.
2. In the ADJ mode, specify the adjustment direction
with the UP/DOWN selector. Each time the SET but-
ton is pressed, the threshold moves up or down. Up to
13 levels can be preset (at Normal one-point, two-point
teaching and Zone one-point teaching).
THRESHOLD indicator light-up in adjusting the sensitivity
Up to 13 levels are adjustable for the normal teaching.
(Up to 5 levels are adjustable for the zone teaching.)
3 . Finally set the MODE selector to the RUN position.
●
THRESHOLD and DISTANCE indicator light-up
・
Light-up in the case of distance setting in normal teaching.
The DISTANCE indicators tell the distances that are
re-lative to the thresholds.
Using the UP/DOWN selector and the SET button, the
threshold can be shifted. The distance differential is fixed,
however.
・
Light-up in the case of distance setting in zone teaching.
The DISTANCE indicators tell the current distance range
that is relative to the threshold.
Using the UP/DOWN selector and the SET button, the
output ON range can be shifted. The distance differential
is fixed, however.
