Approved use

The ultrasonic diffuse-reflection sensors are used as part of a higher-level overall system for the contactless detection of

objects.

Function

The ultrasonic diffuse-reflection sensors operate on the principle of time-of-flight measurement. The device sends a pulse

train, which is then reflected by an object. The device detects the reflected wave and measures the time that has elapsed

between the transmission and reception processes. From this time, the distance between sensor and object is determined.

The results correspond to the specified values, the switching output is set accordingly.

Mounting

The diffuse-reflection sensor can be mounted in any position; however, a vibration-free or vibration-dampening assembly

must be observed. Also protect the device against mechanical stresses such as shocks or impacts.

The transducer surface as well as the field of the detection beam must be kept free mandatorily. You need to pay attention

on having no disturbing objects between the sensor and the target object within the detection beam. It is otherwise possible

that the interfering object causes faulty switching. Also avoid positioning two or more ultrasonic sensors opposite each

other.

Temperature

The speed of sound in air depends on the temperature. Operation outside the specified ambient temperature is not

allowed. A temperature compensation can be switched on via IO-Link.

When temperature compensation is activated, the sensor requires about 15 minutes of warm-up time after a cold start;

only then are the measured values reproducible.

Transmission angle of the object in diffuse mode

Objects with a smooth surface are reliably detected up to a tilting angle

of approx. 10°. The max. allowed tilting angle increases on objects with

a rough or heavy structured (granular) surface.

Blind range in touch mode

The installed focusing nozzle completely covers the blind range of the ultrasonic sensor, so that the device can be used

between 0 and 150mm.

The focusing nozzle must not be removed under any circumstances!

Operation as a reflex barrier can be selected via IO-Link. To do this, set the value 1 to the desired distance from the reference

surface. The selected distance may vary by about 5mm. All objects that interrupt the sound between the sensor and the

reference surface are detected. The blind area may be disregarded in this case.

Cleaning

For cleaning a soft cloth moistened with soapy water is recommended.

Commissioning and setting

The switching points are taught in and the switching output is switched via the connection of the white wire (PIN 2) with

the operating voltage (PIN1).

After 20 seconds, the teach process is aborted (time out function).

Make sure that the object to be detected is always within the adjustable distance limits (20 ... 150mm). In normal operation,

connect the teach line to 0V to avoid interference.

1. Teach-in of a switching window

1. Position the object at the switching limit 1.

2. Connect the white wire to the operating voltage for between 0.1 and 2 seconds. The LED flashes with approx.

1Hz.

3. Position the object at the switching limit 2.

4. Connect the white wire to the operating voltage for between 0.1 and 2 seconds.

5. The switching output is active at a distance between switching limit 1 and switching limit 2.

2. Teaching an object with background suppression (2-point teach)

1. Position the object at the desired position.

2. Connect the white wire to the operating voltage for between 2 and 4 seconds. The LED is blinking with approx.

1Hz.

3. Remove the object from the detection lobe so that the sensor is positioned on the background.

4. Connect the white wire to the operating voltage for between 0.1 and 2 seconds.

5. The switching threshold lies centrally between the object and the background.

3. Automatic teach-in (Auto-Teach)

1. Position the sensor on the background.

2. Connect the white wire to the operating voltage for between 4 and 6 seconds. The LED is blinking with approx.

2Hz.

3. In the next 4 to 8 seconds, pass as many objects as possible past the sensor at the desired distance.

4. The switching threshold is between the object and the background.

4. Change switching function (no / nc)

1. Connect the white wire to the operating voltage for longer than 6 seconds.

2. The switching output now works with the inverted function.

5. LED display after each teach process

If the status LED is blinking twice, the teach process was successful and the sensor is working with the new values.

If the status LED is blinking four times, the teach process has been aborted or the time window of 20 seconds has

been exceeded. The sensor operates with maximum switching distance as a normally open contact.

On the following page, the descriptions are shown again graphically.
