Description of Sensor Function

The ultrasonic sensor works like a retroreflective sensor. It transmits ultrasonic packages in
quick succession and responds to their reflection off a reference object at a defined distance.
The distance T to the reference object can be taught in. The sensor has a switch output. This
output switches if the reference object is not detected, which happens when another object is
located between the sensor and the reference object. The limit of the switching range is de­rived as follows: T - 5 %.

Notes

- The distance T of the reference object must not be changed during operation. If the distance
T changes, it will have to be taught-in again.

- The reference object must not be removed during operation.

Teach-In the Distance to the Reference Object

Proceed as follows to teach in the distance T to the reference object:

1. Connect the sensor and turn on the operating voltage.

2. Place the reference object at the required distance.

3. Connect the teach-in input (ET) to -U

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

(*) 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.

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.
