Safety instructions
General safety notice
WARNING! Not a safety component pursuant to 2006/42/EG and EN 61496-1/-2! May not be used for personal protection! Non-compliance can lead to death or serious injuries! Only use as directed!
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 the object 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.
- Operation is also possible without a crossbar. The crossbar can be taken off by removing both front screws.
- The removal of the crossbar does not increase the detection range.
- The removal of the crossbar has no significant effect on the process value. It is recommended to run a calibration on the reference value via IO-Link.
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 sensitivity potentiometer) 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.
The removal of the crossbar does not increase 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.
Display element

Potentiometer operation
Sensitivity setting (Sens)
Potentiometer at left stop:
Highest sensitivity, for detecting very small objects.
Potentiometer at right stop:
Highest functional reserve, only very large objects can be detected.
NO/NC switching function
Left stop: NO (factory setting)
Right stop: NC
The switch should always be moved to the left or right stop.
Avoid intermediate positions.
Static or dynamic sensor mode (Stat / Dyn)
Left stop: Static (factory setting)
Right stop: Dynamic
The switch should always be moved to the left or right stop.
Avoid intermediate positions.
Switch-off delay (Time)
Potentiometer at left stop:
Switch-off delay 0 ms
Potentiometer at right stop:
Switch-off delay 150 ms
Applications
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 designed for 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. Frame light barriers have 3 or 4 zones depending on their sizes. 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:
- Presence check
- Position check
- Feature check of objects in the detection range.
Applications and configuration recommendation
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

- Zone**
- Stability SSC2***
- Stability SSC1***
- Switching state SSC2

** 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.

Commands: Teach
– Dynamic teach
All sensor modes
Description: Teaching falling objects, larger objects are detected

Allow as many objects as possible to fall through the detection range of the
sensor at different positions.
Command “Teach Stop”.
– Single value teach
only for “Shadowing” sensor mode
Description: The object is taught without a falling motion and a switching
point is set. Once the switching point is reached, the object is detected.

Allow as many type B objects as possible to fall through the detection range
of the sensor at different positions.
Command “Teach Stop”:
If the teach process is successful, falling type A objects are detected with
SSC1 and falling type B objects with SSC2.
A successful teach process is indicated in the teach status.

Other commands
Stopping and starting measurements:
Activating and deactivating sensors
Setting reference values:
Using this function the sensor is calibrated to the measurement value 0 in the
individual installation situation if a free light path is available.
This calibration enables small objects to be better detected for individual installation situations.
There must be no dirt on the front panel during the calibration.
The calibration takes place without objects in the detection range using the command “Set reference value”.
Deleting reference values:
This function is used to reset the calibration value to the factory setting.
