MOUNTING THE SENSOR
WayCon Positionsmesstechnik GmbH would like to thank you for the trust you have placed in us and our
products. This manual will make you familiar with the installation and operation of our ultrasonic sensors.
Please read this manual carefully before initial operation!
Unpacking and checking:
Carefully lift the device out of the box by grabbing the housing. After unpacking the device, check it for
any visible damage as a result of rough handling during the shipment. Check the delivery for
completeness. If necessary consult the transportation company, or contact WayCon directly.
ELECTRICAL CONNECTION
The sensor can be mounted with the two M12 nuts (HEX 17) which are included in the delivery.
Ultrasonic sensors may be installed in any position, as long as depositions like dust, spray mist, or
condensing humidity are avoided on the sound active membrane.
In case several ultrasonic sensors are used in one application, it is important to leave sufficient distance
between them. Otherwise the sensors may interact which leads to false measurement values.
By using a sound deflection angle the sound beam can be redirected, at the expense of the sensor's
maximum measurement range. A plain and hard surface should be used for the defection of the sound
beam. Redirecting the sound beam with multiple sound deflection angles should be avoided.

SOUND CONE GEOMETRY
The exact geometry of the sound cone depends on the air-pressure, temperature, humidity and the size
of the target.
Smooth surfaces can be detected up to an inclination angle of 10°. However rough and structured
(granular) surfaces can be detected up to higher angles.

ANALOG OUTPUT
UFA...CU / CI
The two measuring limits are set by connecting the teach wire with either the power supply -UB (0 V) or
+UB (+24 VDC). The voltage must be active for at least 1 s on the teach wire. During teaching the LED
shows if the sensor has detected the object. With -UB the lower measuring limit (0 V or 4 mA) and with
+UB the upper measuring limit (10 V or 20 mA) is taught. Thus it is possible to teach a rising or a falling
ramp.
● Place the object to the lower measuring limit (where 0 V or 4 mA is expected)
● Teach lower measuring limit with -UB
● Place the object to the upper measuring limit (where 10 v or 20 mA is expected)
● Teach upper measuring limit with +UB
Upper and lower measuring limits can be reprogrammed at any time.
Attention: The teach wire must not be connected during normal operation. The sensor can therefore be
operated after teaching with a 3 wire cable.

NOTES
Warning
These devices are not designed for critical safety or emergency shut-down purposes. Therefore they
should never be used in an application, where a malfunction of the device could cause personal injury.
Environmental Influences
Ultrasonic sensors are made for the use in atmospheric air. Environmental Influences like rain, snow, dust
or smoke have no influence on the accuracy of the measurement. However, measurements under
pressure (higher that the atmospheric pressure) are not possible with ultrasound sensors.
Strong wind or air turbulences may lead to instability in measurement values. A flow speed up to a few
m/s is unproblematic and will have no influence on the sensor's accuracy.
Target Influences
Liquids
are excellently detectable with ultra sound. A classic application for ultrasonic sensors is level
measurement. The sound beam axis however must have a maximum deviation of 3° vertically to the
liquid level (no strong waves), otherwise the reflected sound will miss the sensor.
Hot Targets
with high temperatures cause a thermal convection in the surrounding air. For this reason the sound
beam may be strongly diverted vertically to it's axis, so that the echo is weakened, or can no longer be
received at all.
For convex (cylindrical and spherical) surfaces,
every area element has a different angle to the sound cone’s axis. The reflected cone thus diverges and
the portion of the sound energy reflected to the receiver is reduced correspondingly. The maximum range
decreases with the decreasing size of the cylinder (ball).
The roughness and surface structures of the object
to be detected also determine the scanning capacities of the ultrasonic sensors. Surface structures that
are larger than the ultrasound wavelength, as well as coarse-grained bulk materials, reflect ultrasound in
a scattered manner, and are not detected optimally by the sensor under these conditions.
Hard material
reflects almost all of the impulse energy from ultrasound applications in a way that makes them very easy
to detect with ultrasound.
Soft material,
on the other hand, absorbs almost all of the impulse energy. It is thus harder to detect with ultrasound.
These materials include felt, cotton, coarse meshes, foam, etc.
Thin-walled foils
behave like soft materials. To be able to use ultrasound, the foil thickness should be at least 0.01 mm.
