The bks+ sensors are IO-Link-capable
in accordance with IO-Link specifica-
tion V1.1.
Via the Teach-in button on the
edge sensor’s top, 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.
Safety Notes
Read the operating instructions
prior to start-up.
Connection, installation and ad-
justment works may only be car-
ried out by expert personnel.
No safety component in ac-
cordance with the EU Machine
Directive.
Installation
Mount the sensor at the installa-
tion site.
Connect a connection cable to
the M12 device plug.
For optimum measurement re-
sults the sensor should be moun-
ted thermally conductive.
Start-Up
Connect the power supply.
Carry out the adjustment in ac-
cordance with the diagram.
Synchronisation
If two or more edge sensors are
mounted in a distance < 400 mm
the internal synchronisation should
be used. Connect Sync-channels (Pin
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.
5 at the units receptacle) of all sen-
sors.
Factory setting
Analogue output on voltage out-
put.
Rising analogue characteristic (0
V at maximum coverage).
Switched output on NCC.
Switched output window is ± 1,5
mm around zero position.
Maintenance
microsonic sensors are maintenance-
free. With heavy dirt deposits, we re-
commend a cleaning of the white
sensor surface.
Note
For optimum measurement re-
sults the material to be detected
should be kept in a range of ± 5
mm around the centre between
the upper and lower fork leg.
Using the LinkControl-Adapter
LCA-2 (optional accessory) and
the LinkControl-Software V7.6
all Teach-in- and additional sen-
sor parameter settings may be
made.
Depending on the function the
ultrasonic transducers in the up-
per and lower fork leg are
mounted with a slope of 2°.
