Model selection
The UPS versions have different outputs.
UPS … TVPA 24 C
Ultrasonic sensor with a binary output with 2 teachable
switching points (NO, NC or window function).
UPS … TOR 24 CA
Ultrasonic sensor for distance measurement with an
analogue output 0...10V. The lower and upper limits are
teachable.
UPS … TOR 24 CI
Ultrasonic sensor for distance measurement with an
analogue output 4...20mA. The lower and upper limits are
teachable.
Blind range
The lower detection range is called blind range. It is typical
for ultrasonic sensors. In the blind range no distance
measurement is possible! However the pure function as
proximity switch (binary output) is possible in the blind range
with certain restrictions (only bigger objects).
Setting of the switching points (UPS … TVPA 24 C)
The switching points are set by connecting the teach wire
with either the power supply –U
B
(0V) or +U
B
(+24VDC). The
voltage must be active for min. 1s on the teach wire. The
LED shows during teaching if the sensor has detected the
object.
Window operation NO
 Place the object to the near switching point
 Teach switching point with –U
B
 Place the object to the far switching point
 Teach switching point with +U
B
Window operation NC
 Place the object to the near switching point
 Teach switching point with +U
B
 Place the object to the far switching point
 Teach switching point with -U
B
Switching point NO
 Place the object to the switching point
 Teach switching point with +U
B
 Cover the sensor diaphragm by hand or let the sensor
look into the void
 Teach with -U
B
Switching point NC
 Place the object to the switching point
 Teach switching point with –U
B
 Cover the sensor diaphragm by hand or let the sensor
look into the void
 Teach with +U
B
Application hint window operation
(UPS … TVPA 24 C)
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-reflective sensor. The
reflector 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
flat angle. The sensor would not detect such targets in
normal scan operation mode.
Setting the measuring limits (UPS … TOR 24 CA/I)
The two measuring limits are set by connecting the teach
wire with either the power supply –U
B
(0V) or +U
B
(+24VDC).
The voltage must be active for min. 1s on the teach wire. The
LED shows during teaching if the sensor has detected the
object. With -U
B
the lower measuring limit (0V or 4mA) and
with +U
B
the upper measuring limit (10V or 20mA) is taught.
Thus it is possible to teach a rising or a falling ramp.
