General notes

Intended use

Frame light barriers are sensors with an integrated transmitter and receiver. These sensors are used for the contact-free detection of objects.

Assembly

The frame light barrier should be installed so that theobject to be detected can freely pass through the detection range.

• Device-specific information on connection and operation must be observed.
• Mount the sensor at the mounting holes, maximum torque of M4 mounting screws: 1.4 Nm.
• The sensor may be mounted in any installation position, as long as mounting is performed free of vibration.
• The sensor must be protected from mechanical loads such as shocks and impacts.

Ambient light

If several frame light barriers are used in close proximity, this can lead to mutual influencing. Make sure that the frame light barrier transmitter (connector side) does not radiate into the receiver (side of – button) of a neighboring frame light barrier.

Assembly options

• Arrange neighboring frame light barriers offset by 180°
• Mechanically shadow neighboring frame light barriers

Detection range

• The objects to be detected must be located within the detection range.
• The resolution can be reduced slightly on the edge regions of the detection range.

Temperature range

• Operation outside of the specified temperature range is not allowed.

Front panel

• There may be no dirt on the front panels. The front panel should be cleaned with a soft, dust-free cloth.

Keypad operation

Sensitivity adjustment

Auto-teach

• Falling objects can be taught using auto-teach, larger objects are detected
• Press the + button for 2-4 sec. for the teach process. The teach process starts. Allow as many objects as possible to fall through the detection range of the sensor at different positions.
• Pressing the + button again will end the teach process. Alternatively, the sensor will end the process automatically after 60 sec.

LED displays

• Rapid blinking LED3 (yellow): Teach process has started Flashes 2x LED3 (yellow): Switching point determined, teach  process ended successfullyFlashes 4x LED3 (yellow): No suitable switching point determined, teach process ended
• Note : If no object was run through the sensor during the teach process, then the switching point will be set to the highest sensitivity. LED3 (yellow) flashes 4 times.

Manual adjustment of sensitivity

• Briefly pressing the + and – buttons will adjust the switching point of switching output 1 in small increments. Each press of the button will increase/decrease the switching point by10.
• Increasing the sensitivity for detecting smaller objects : Briefly press – to increase sensor sensitivity.
• Reducing the sensitivity to increase the functional reserve : Briefly press + to decrease sensor sensitivity.

LED displays :

• Flashes 1x LED3 (yellow): Switching point has been shifted
• Flashes 4x LED3 (yellow): Switching point has been reached

Changing the sensor mode to static/dynamic

LED display

LED2 (white) on : Dynamic sensor mode active

Changing to NO/NC

• Pressing the + button for > 6 sec. will switch the switching output between NO/NC

Setting a reference value

• Using this function, the sensor is calibrated to the measurement value 0 in the individual installation situation.

• No objects may be in the detection range during the calibration.
• Press the – button for > 6 sec., the calibration will start and end automatically.

LED displays

Setting a reference value C

• Activate Pin 2 for 4 to 6 sec, the calibration process starts and then ends automatically.
• Notes and LED display, see reference value keypad operation.

Changing to NO/NC D

• Activate Pin 2 for >6 sec, the switching output switches between NO/NC.

Status notifications E

• LED2 (yellow) flashes 2x teach / change successful
• LED2 (yellow) flashes 2x teach unsuccessful

Applications in detail

• Frame light barriers detect objects in the detection range of the sensor independent of the position of the object. Using the IO-Link configuration, frame light barriers can be used for many applications.

Detecting and counting falling objects

• Frame light barriers can be used for detecting and counting rapidly falling objects within the detection range of the sensor. The frame light barrier factory default setting is designedfor this application (static sensor mode).

Static and dynamic sensor mode

Static : The sensor detects moving and static objects in the detection range.
Dynamic : The sensor only detects moving objects in the detection range. Objects that are continually in the detection range (e.g. transparent tubes, feed rails or soiling) are suppressed.

Verifying falling objects

• Using IO-Link, frame light barriers can be configured to verify an object based on the shadowing. Larger and smaller objects are not detected as the taught object

Differentiating between falling objects

• Using IO-Link, frame light barriers can be configured to distinguish between two different objects. The distinction is made due to the different shadowing.

Determining the zone of falling objects

• Using IO-Link, frame light barriers can detect in which zone (area) an object has fallen through the detection range. OGWTI series frame light barriers have 3 zones. Ideally, the object should fall through the center of the zone.

Checking objects without a falling motion

Using IO-Link, frame light barriers can be configured to check objects without a falling motion, e.g. for a:

1. Presence check
2. Position check
3. Feature check of objects in the detection range.

Description of sensor modes

Static

• The sensor detects moving and static objects within the detection range.

Dynamic

• The sensor only detects moving objects in the detection range. Objects that are continually in the detection range (e.g. transparent tubes, feed rails or soiling) are suppressed.

Shadowing (only with IO-Link)

• Used for presence, position and feature checks. The process value steadily increases with an increasing beam shadowing from the immersed objects.

Peak value (only with IO-Link)

• Used to distinguish between and verify falling objects based on size. The evaluation takes place after a time period, which depends on the object distance parameter.

IO-Link Interface

• IO-Link version: IOL V1.1.3, COM2 (38.4k baud) Profile smart sensors 2nd Edition V1.1 SSP 4.1.1
• Recommended: IOL-Master with software version: V5.1 or higher or IOL-Portable

IO-Link process data

1. Measured value: Shadowing in detection range*
2. Zone**
3. Stability SSC2***
4. Stability SSC1***
5. Switching state SSC2
6. Switching state SSC1

no shadowing: Value 0, small objects: small values, larger objects: larger values

• ** region of falling object
• *** evaluation of stability: IO-Link display (NOK) for switching channel 1 and 2 if object detection is impaired, e.g. by soiling. After cleaning and with sufficient functional reliability, NOK is reset. The reset requires that a switching operation is generated after cleaning.
