Scanning range far limit (Sde)The far limit of the sensing range.
Sensing range (Sd)The area between the blind range far limit and the scanning range far limit.

1. Indicator modes* The orange LED could be out for any of the following reasons: There is no target. The target is out of range. The target is within the blind range. The ultrasonic reflection from the target is too weak.
2. Operating the Teach-In button
Set the scanning range as follows.
Press the button for 2 to 6 seconds unti l the indicator bl inks
alternately orange and red.
Release the button and the indicator will begin to blink red.
Place the target at the 0 Vdc or 4 mA output position and press the
button. The indicator begins to blink orange.
Place the target at the 10 Vdc or 20 mA output position and press
the button to complete setup. The interval between the two set
points is linearly interpolated.
2.1 Setting a scanning range
Use the Teach-In button for setup. Setup should be completed within five minutes after power-up. The settings are fixed after five minutes to
prevent them from being accidentally changed during regular operation. Even after the power is turned off, the settings are saved.

Do not allow water to enter.
The output will be unreliable if the target is outside of the
measurement range setting.
When two or more sensors are used in close proximity, mutual
interference may cause the sensors to malfunction. Maintain at
least the distances indicated in the figures below.
Parallel sensors facing each other (keep the same distances if the
sensors face in the same direction)
Sensors mounted back to back
Be sure to turn off the power before mounting the sensor.
Do not pull excessively on the sensor cable.
Do not use the sensor in a place exposed to water or oil, outdoors,
or in an atmosphere with chemicals (organic solvents, acids, and
alkalies).
To prevent malfunction and device failure, always use the sensor
within the rated temperature.
An airflow of more than 10 m/s within the sensing area may alter
the sensing area boundaries.
Avoid local differences in temperature and strong convection
phenomena, because abrupt changes in airflow in the sensing
area may cause the sensor to malfunction.
A jet of air from an air nozzle may cause the sensor to malfunction.
Do not use near an air nozzle or the like.
Due to fundamental principles, the output may be unreliable in an
environment where the pressure fluctuates. Check the output
under the actual operating conditions before using the sensor.
Because the sensor does not have a pressure-resistant structure,
it should be used at atmospheric pressure.
Water drops or dust on the sensing face may make the output
signals unstable.
Since the end of the cable is outside of the protective structure,
take care to prevent water from entering from the end.
Sound-absorbing materials, such as cotton and fine powder,
cannot be detected.
If there is an ultrasonic cleaner or other ultrasonic equipment in the
area, separate it sufficiently from the sensor and verify that it does
not cause ultrasonic interference.
The sensor may not detect a target whose surface is convex,
concave, or tilted toward the sensor.

Route the cable separately from power lines or though a separate
conduit. Otherwise, induction may cause incorrect operation or
damage.
If a switching regulator is used for the power supply, connect the
frame ground and ground terminal to ground. If the sensor is used
without grounding, faulty operation may occur due to switching
noise.
Although the sensor has a miswiring protection circuit, incorrect
wiring involving the input/output terminals may cause damage.
Diffuse reflection from surrounding objects because of ultrasonic
diffusion or sidelobes may cause incorrect detection. If measurement
is incorrect, consider the following countermeasures: keep the
sensor away from the surrounding objects, use sound-absorbing
materials like sponge, or install sound-insulating barriers.
When setting 0 Vdc or 4 mA output, place the target far from the sensor.

3. Handling precautions
4. Influence by diffuse reflection from surrounding objects
5. Wiring precautions
It is possible to revert the settings to the factory defaults by either of
the following methods:
1.
Press the button for more than 6 seconds until the indicator rapidly
blinks alternately orange and red.
Release the button, and the indicator will light orange and red at
the same time for 2 seconds. The sensor has been reset to the
factory defaults.
2.
Set a scanning range without a target. The indicator will rapidly
blink alternately orange and red for 2 seconds. The sensor has
been reset to the factory defaults.
2.2 Factory defaults
Before use, thoroughly read the Precautions for use and Precautions for handling in the Technical Guide on pages B-021 to B-024 as well as the instruction manual and product specification for this sensor.
