bks+3/FIU Ultrasonic web edge sensor with analogue output and IO-Link interface

Product Description The bks+ ultrasonic web edge sensor is a fork sensor for scanning the edges of sound-impermeable materials such as foil or paper. The fork's lower leg is equipped with an ultrasonic sensor which cyclically emits short sound impulses, which are detected by the ultrasonic receiver accommodated in the upper fork leg. Material immersing into the fork covers this sound path and thus attenuates the receive signal, which is evaluated by the internal electronics. An analogue signal is output in dependence of the coverage degree. Using the LinkControl-Adapter LCA-2 and LinkControl software, the switched output can be programmed in window mode around the zero position.

Via the Teach-in button on the edge sensor's top or via Pin 5 on the device plug, the sensor can be adjusted to the material to be controlled.
Choosing between rising and falling output characteristic is possible.
Three LEDs indicate the position of the web material inside the fork.
IO-Link The bks+3/FIU sensors are IO-Link-capable in accordance with IO-Link specification V1.1.
Safety Notes Read the operating manual prior
to start-up. Connection, installation and ad-
justment works may only be carried out by expert personnel. No safety component in accordance with the EU Machine Directive.

Installation Î Mount the sensor at the installation
site. Î Connect a connection cable to the
M12 device plug, see Fig. 1. Î For optimum measurement results
the sensor should be mounted thermally conductive.
Start-Up Î Connect the power supply. Î Carry out the adjustment to the
web material in accordance with Diagram 1.
Synchronisation If two or more edge sensors are mounted in a distance <400 mm the internal synchronisation should be used. Connect Sync-channels (Pin 5 at the units receptacle) of all sensors.

Notes
For optimum measurement results the material to be detected should be kept in a range of ±5 mm around the centre between the upper and lower fork leg.
The sensor can be reset to its factory settings (see »Further settings«, Diagram 1).
Carry out the adjustment only after reaching the operating temperature (approx. 20 min).
Using the LinkControl-Adapter LCA-2 (optional accessory) and the LinkControl-Software V7.6 additional sensor parameters can be adjusted and Teach-in procedures can be carried out.
Depending on the function the ultrasonic transducers in the upper and lower fork leg are mounted with a slope of 2°.

IO-Link-Mode
The bks+3/FIU sensors are IO-Link-capable in accordance with IO-Link specification V1.1 and compatible to specification V1.0.
Note In IO-Link mode Teach-in and LinkControl are not available.
Process data The bks+ cyclically transmits the value corresponding to the measured coverage degree with a resolution of 0.003 mm.
Service data The following sensor parameters may be set via IO-Link.

Teach-in via push-button The push-button can be activated/ deactivated for sensor settings with Teach-in.
Linearisation of the output characteristic The linearisation of the output characteristic increases the accuracy in the central measuring range of the sensor. If higher accuracy is required in the edge areas, the linearisation of the output characteristic can be deactivated.
Temperature compensation The temperature compensation is used for measurement value correction for varying ambient temperatures and can be disabled.

Analogue output mode For the analogue output either voltage or current output can be selected.
Rising/falling analogue characteristic The analogue characteristic can be set on rising (0 V/4 mA at full coverage) or falling characteristic.
Set NOC/NCC The NCC or NOC output function can be preset for the switching output.
Switching off the LEDs When activated, the LEDs are turned off 30 seconds after a key press. After a new key press they will run for 30 seconds. This automatic shutdown can be deactivated.

Measurement filter bks+ ultrasonic sensors provide for a choice of 3 filter settings: F00 (no filter)
Each ultrasonic measurement acts on the output in an unfiltered manner.
F01 (average value filter) Forms approximately the arithmetic mean of several measurements. According to the mean value the output is set. The number of measurements, from which the mean is formed is dependent on the chosen filter strength.
F02 (median filter) Finds the median of several measurements. According to the median the output is set. The number of measurements, for which the median is determined is dependent on the selected filter strength.
Filter strength For both measurement value filters, a filter strength between P00 (weak filter effect) and P09 (strong filter effect) can be selected.
Switching window If the web edge is within the switching window the switching output is set. The switching window is defined by the adjusted centre and the width.
Note The switching window has to be within the operating range.

System commands With 5 system commands the following settings may be carried out: restore IO-Link parameters to their
factory settings (system command 130) sensor adjustment: fork cleared sensor adjustment: fork 50 % covered sensor adjustment: fork 100 % covered reset all sensor parameters including the IO-Link parameters to their factory settings (system command 164)
Events The bks+ sensor sends the following events: parameter was changed sensor adjustment successful sensor adjustment failed
