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.
MOUNTING THE SENSOR
• 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.
• It is important to avoid structure-borne sound bridges between the sensor and its holder.
• In case several ultrasonic sensors are used in one application, it is important to leave sucient
distance between them. Otherwise the sensors may interact which leads to false measurement
values.
• By using a sound deection 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 deection angles should be avoided.

TEACHING THE ANALOG OUTPUT
Every sensor is delivered with the factory set-up (max. measurement range). The teach-in feature is
designed to choose a smaller range within the nominal measuring range for optimizing the resolution
and linearity. Output current, or output voltage adapt to the new range and get new characteristic
curves. The two positions P1 and P2 must be taught.
Characteristics
P1 and P2 dene the analog output slope.
P1 determines the 0 V / 4 mA position and P2 the 10 V / 20 mA position.
P1 P2
4 mA / 0 V
20 mA / 10 V
Positive slope: P1 < P2
P2 P1

Negative slope: P2 < P1
Teach-In of P1 (SP1 position)
Connect Teach-In line with GND until P1 and Echo LEDs start blinking with a 2 Hz frequency (UFP-200
just yellow). Release the contact. The sensor is now in the Teach-In mode for P1: P1 LED will now blink
with 1 Hz frequency (UFP-200 with ½ Hz) and the Echo LED will go back to normal function (alignment
LED). There is a time window of 30 seconds to do the programming of P1. Place the target at the new
position P1. Connect and release Teach-In line with GND: P1 is now programmed. Sensor returns to
normal function with the new value for P1.

TEACHING THE ANALOG OUTPUT
Teach-In of P2 (SP2 position)
Connect the Teach-In line with GND until the P2 and Echo LEDs start blinking with a 2 Hz frequency
(UFP-200 just yellow, 1 Hz). First P1 and Echo LEDs will be blinking, but it is important to wait to reach
P2. The sensor is now in the Teach-In mode for P2: P2 LED blinks with 1 Hz frequency now (UFP-200
just yellow, ½ Hz). The Echo LED returns to normal function (alignment LED). There is a time window
of 30 seconds to do the programming of P2. Place target at the new position P2. Contact and release
the Teach-In line with GND: P2 is now programmed. Sensor returns to normal function with the new
value for P2.
TEACHING THE SWITCHING OUTPUT
The teaching procedure is used to set the operation mode of the switching output and the 2 switching
points.
Three dierent modes of switching outputs can be selected:
• Normal switching function
• Window function
• Adjustable hysteresis
All these functions will be taught with the Teach-In line present in the connector. Each mode has a
dierent sequence using the Echo, P1 and P2 LEDs. The diagram displays the timing.
Window function mode:
SP1 is switching when object is
between P1 and P2. SP2 is switching
when the object is NOT between P1
and P2.
Selection of hysteresis mode:
Hysteresis adjustment of SP1 at
P1. Distance between P1 and P2
determines the hysteresis of the
switching outputs. SP1 has NO
(opener) and SP2 has NC (closer)
characteristics.
Teach-In of switching output

The switching output can

Normal Switching Function
Teach-In of P1 (SP1 position):
Connect Teach-In line with GND until P1 and Echo LEDs start blinking with a 2 Hz frequency and
then release the contact. The sensor is now in Teach-In mode for P1: P1 LED will now blink with 1 Hz
frequency and the Echo LED will go back to normal function (alignment LED). There is a time window
of 30 s to do the programming of P1. Place the target at the new position P1. Contact and release
Teach-In line with GND: P1 is now programmed. Sensor returns into normal function with new value
for P1.

TEACHING THE SWITCHING OUTPUT
Teach-In of P2 (SP2 position):
Connect the Teach-In line with GND until the P2 and Echo LEDs start blinking with a 2 Hz frequency.
First P1 and Echo LEDs will be blinking but it is important to wait to reach P2. The sensor is now in
Teach-In mode for P2: P1 LED blinks with 1 Hz frequency now. The Echo LED returns to normal function
(alignment LED). There is a time window of 30 s to do the programming of P2. Place target to the new
position P2. Contact and release the Teach-In line with GND: P2 is now programmed. Sensor returns
into normal function with new value for P2.
Switching output characteristics:
The output characteristics can be selected during Teach-In of the set points P1 and P2. For each set
point and during the teaching procedure, when the LED is ON when contacting and releasing the
Teach-In line to GND, the switching output will have NO characteristics, when doing this when the LED
is it OFF, the switching output will have NC characteristics.

Window function / Hysteresis adjustment
Connect the Teach-In line with GND until P1, P2 and Echo LEDs start blinking with a 2 Hz frequency.
Before reaching the hysteresis Teach-In mode, the sensor will go through the P1 and P2 teaching
sequence. Keep the Teach-In line connected to the GND until reaching the point when all LEDs are
blinking with a 2 Hz frequency. Release the Teach-In line contact. The sensor is now in Teach-In mode
for window function/ hysteresis adjustment: P1+P2 LEDs are blinking with a 1 Hz frequency. The Echo
LED returns to its normal function (alignment LED). There is a time window of 30 s to complete the
programming. Contact and release the Teach-In line with GND.
Pay attention to P1 and P2:
If P1+P2 LEDs are OFF during the contact
with the Teach-In line, the sensor will operate
the in window function: If there is an object
between P1 and P2, SP1 will switch ON and
SP2 will switch OFF. If there is no object
between P1 and P2, SP1 will switch OFF and
SP2 will switch ON.
If P1+P2 LEDs are ON during contact, the
sensor will operate in hysteresis mode: The
switching output SP1 will be (NO) at P1 with
hysteresis P1-P2 and switching output SP2
will be (NC), also at P1 with hysteresis P1-P2.

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.
