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

B

. This can be done usingthepushbutton or the controller.

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 flashing at a faster rate. The switching point remains

unchanged.
