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 progammable (Teach-In). Objects beyond the taught-in switching point are not detected (background
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
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
(*) If no object is detected within the sensing range of the sensor, the sensor will start flashing at a faster rate. The switching point remains
unchanged.
. This can be done usingthepushbutton or the controller.

Mounting instruction
If the sensor is operated at temperatures below 0 °C, use the supplied distance plate. Only use the two rearmost mounting holes (located opposite
to the transducer) for mounting the sensor.
Safety Note
The use of this device in applications, where the safety of persons depends from the devices function, is not allowed!
