Description of Sensor Function
The ultrasonic sensor transmits ultrasonic packets in quick succession and responds to their
reflection off the detected object. The sensor has a switch output. The switching point is pro-
gammable (Teach-In). Objects beyond the taught-in switching point are not detected (back-
ground suppression).
Teach-In of Switching Point SP
To teach in a switching point, proceed as follows:
1. Connect the sensor and turn on the operating voltage.
2. Place the object to be detected at the required distance.
3. Connect the teach-in input (ET) to -U
B
. This can be done usingthepushbutton or the con-
troller.
The LED will start flashing after 3 seconds to indicate that the sensor is ready to start the
teach-in process

.
4. Disconnect the teach-in input (ET) with -U
B
. The switching point SP has now been taught
in

.
(*) If no object is detected within the sensing range of the sensor, the sensor will start flash-
ing at a faster rate. The switching point remains unchanged.
