FIRST STEPS
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.
SAFETY NOTICES
• These products are neither allowed to be used as safety- or emergency shut-o devices, nor in other
applications, where a malfunction of this product may result in personal injury.
• Failure to follow this notice may result in serious or fatal injury.
MOUNTING NOTICES
• The sensor can be mounted with the two M12 nuts (UFA2/UFA-CP) or M30 nuts (UFA-6000) which
are included in the delivery.
• The sensor has to be protected against mechanical loads for example shocks and impacts.
• The sensor can be mounted in any position, however a vibration-free or vibration-dampening
assembly must be observed.
• The transducer surface as well as the eld of the detection beam must be kept free mandatorily. You
need to pay attention on having no disturbing objects between the sensor and the target object
within the detection beam. Otherwise the sensor will detect the disturbing object instead of the
target object required.
• The object reects a part of the ultrasonic in the
diuse mode - this reected sound will be evaluated
by the sensor. Objects with a smooth surface are
reliably detected up to a tilting angle of approx. 10°.
The max. allowed tilting angle increases on objects
with a rough or heavy structured (granular) surface.

TEACHING FUNCTION UFA2 AND UFA6000 ANALOG OUTPUT
Teaching the measurement range:
The measuring range is dened by two teach points. The output signal is scaled to the taught
measuring range.
Procedure:
1. Place the target on the position of the 1st teach point (i.e. where 0 V or 4 mA should be output).
2. Connect the teaching line (Pin 4) with +V (Pin 1) for 0.1...2 s. LED ashes slowly (1 Hz).
3. Within <20 s, place the target on the position for the 2nd teach point (i.e. where 10 V or 20 mA
should be output) and connect the teaching line with +V for 0.1...2 s.
4. LED ashes 2 times: teach procedure successful
LED ashes 4 times: teach procedure not successful
Changing the analog output signal:
The physical quantity (current/voltage) of the analog output is changed.
Procedure:
1. Connect the teaching line (Pin 4) with +V (Pin 1) for >6 s.
2. LED ashes 2 times: change successful
LED ashes 4 times: change not successful

TEACHING FUNCTION UFA2 AND UFA6000 SWITCHING OUTPUT
Teaching the window size:
The window size is dened by two switching limits.
Procedure:
1. Place the target on the position of near switching point.
2. Connect the teaching line (Pin 2) with +V (Pin 1) for 0.1...2 s. LED ashes slowly (1 Hz).
3. Within <20 s, place the target on the position of the far switching point and connect the teaching
line with +V for 0.1...2 s.
4. LED ashes 2 times: teach procedure successful
LED ashes 4 times: teach procedure not successful
2-step teaching:
Both conditions (background and object) can be taught successively. The switching point is placed
between the object and the background.
Procedure:
1. Place the target on the position of near switching point.
2. Connect the teaching line (Pin 2) with +V (Pin 1) for 2...4 s. LED ashes slowly (1 Hz).
3. Within <20 s, remove the target and connect the teaching line with +V for 2...4 s.
4. LED ashes 2 times: teach procedure successful
LED ashes 4 times: teach procedure not successful
Autoteach procedure:
Opens a teach window for 4...8 s and automatically teaches passing objects. The switching point is
placed between the object and the background.
Procedure:
1. Connect the teaching line (Pin 2) with +V (Pin 1) for 4...6 s. LED ashes fast (2 Hz).
2. Within the next 4...8 s, the autoteach procedure detects passing objects.
3. LED ashes 2 times: teach procedure successful
LED ashes 4 times: teach procedure not successful
Changing the switching function:
Changes between NO <=> NC. Causes a inversion of the switching output function (signal inversion on
objects within / outside the window).
Procedure:
1. Connect the teaching line (Pin 2) with +V (Pin 1) for >6 s.
2. LED ashes 2 times: change successful
LED ashes 4 times: change not successful

TEACHING FUNCTION UFA150CP ANALOG OUTPUT
Teaching the measurement range:
The two measuring limits are set by connecting the teaching line with either the power supply GND
(0V) or +V (+24 VDC). The voltage must be active for min. 1 s on the teaching line. During the teaching
procedure the LED shows if the sensor has detected the object. With GND the lower measuring limit
(0V or 4 mA) and with +V the upper measuring limit (10 V or 20 mA) is taught. Thus, it is possible to
teach a rising or a falling ramp.
Procedure:
1. Place the object on the lower measuring limit (i.e. where 0 V or 4 mA is desired).
2. Connect the teaching line with GND for >1 s.
3. Place the object on the upper measuring limit (i.e. where 10 V or 20 mA is desired).
4. Connect the teaching line with +V for >1 s.
Lower and upper measuring limits can also be programmed individually at a later time.
Attention: The teach wire must not be connected during normal operation. Those the sensor can be
operated after teaching with a 3 wire cable.
TEACHING FUNCTION UFA150CP SWITCHING OUTPUT
Setting of the switching points:

4. Teach with GND
Switching point opener NC:
1. Set target to switching point
2. Teach switching point with GND
3. Point sensor at space (>1.5 m)
4. Teach with +V

TEACHING FUNCTION UFA150CP SWITCHING OUTPUT
Retroective mode:
In window operation the sensor detects only targets which are within the window limits. The same
function can also be used to simulate a kind of retro-reective sensor. The reector is mounted in the
small window between Teach A and Teach B (see drawing below). In such setup the sensor detects also
targets which pass the sensor beam in a very at angle. The sensor would not detect such targets in
normal scan operation mode.

INFLUENCES ON THE MEASUREMENT
Environmental inuences:
Ultrasonic sensors are made for the use in atmospheric air. Environmental Inuences like rain, snow,
dust or smoke have no inuence 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 ow speed up to a few
m/s is unproblematic and will have no inuence on the sensor’s accuracy.
Target Inuences:
• Liquids are excellently detectable with ultrasound. 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 reected 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 its 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 dierent angle to the sound
cone’s axis. The reected cone thus diverges and the portion of the sound energy reected 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, reect ultrasound in a scattered manner, and
are not detected optimally by the sensor under these conditions.
• Hard material reects 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.
