Microsonic IO-Link sks-15/CF/A User manual

Product Description
The sks sensor offers a non-con-
tactmeasurement of the distance to an
object which must be positioned
within the sensor‘s detection zone.
The switching output is set in depen-
dance of the adjusted detect distance.
Via the push-button, the distance and
operating mode can be adjusted
(Teach-in). Two LEDs indicate the state
of the switching output.
The output function is changeable
from NOC to NCC.
IO-Link
The sks sensor is IO-Link-capable in
accordance with IO-Link specication
V1.1 and supports Smart Sensor Pro-
le like Digital Measuring Sensor.
Safety Notes
Ԏ
Read the operation manual prior
to start-up.
ԎConnection, installation and ad-
justment works may only be car-
ried out by expert personnel.
Ԏ
No safety component in ac-
cordance with the EU Machine
Directive, use in the area of per-
sonal and machine protection
not permitted
Use for intended purpose only
sks ultrasonic sensors are used for
non-contact detection of objects.
Installation
Î

Operating modes
Three operating modes are available
for the switching output:
Ԏ
Operation with one switching
point
The switching output is set if the
object falls below the set switching
point.
ԎWindow mode
The switching output is set if the
object is inside the set window li-
mits.
ԎTwo-way reective barrier
The switching output is set if there
is an object between sensor and
reector.
Checking operating mode
Î
In normal operating mode shortly
press the push-button. The green
LED stops shining for one second,
then it will show the current ope-
rating mode:
Ԏ1x ashing = operation with one
switching point
Ԏ2x ashing = window mode
Ԏ3x ashing =reective barrier
After a break of 3 s the green LED
shows the output function:
Ԏ1x ashing =NOC
Ԏ2x ashing =NCC
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend to clean the white
sensor surface.
Notes
Ԏ
Every time the power supply is swit-
ched on, the sensor detects its ac-
tual operating temperature and
transmits it to the internal tempera-
ture compensation. The adjusted
value is taken over after 45 seconds.
Ԏ
If the sensor was switched off for at
least 30 minutes and after power
on the the switching output is not
set for 30 minutes a new adjust-
ment of the internal temperature
compensation to the actual moun-
ting conditions takes place.
Ԏ
The sks sensor has a blind zone
whitin which distance measure-
ments are not possible.
ԎIn the normal operating mode, an
illuminated yellow LED signals the
switching output is switched
through.
Ԏ
In the »Set switching point – me-
thod A« Teach-in procedure the
actual distance to the object is
taught to the sensor as the swit-
ching point. If the object moves
towards the sensor (e.g. with level
control) then the taught distance is
the level at which the sensor has to
switch the output (see Fig.2).

detection zones
for different objects:
The dark grey areas represent the
zone where it is easy to recognise
the normal reector (round bar).
This indicates the typical opera-
ting range of the sensors. The
light grey areas represent the
zone where a very large reector
– for instance a plate – can still
be recognised. The requirement
here is for an optimum alignment
to the sensor. It is not possible to
evaluate ultrasonic reections
outside this area.

ԎIf the object to be scanned moves
into the detection area from the
side, the »Set switching point +8 %
– method B« Teach-in procedure
should be used. In this way the swit-
ching distance is set 8 % further
than the actual measured distance
to the object. This ensures a reliable
switching distance even if the
height of the objects varies slightly,
(see Fig.2).
Level control Object detection
Fig.2: Teach-in for dierent directions of
movement of the obcject
ԎIn the »Two-way reective barrier«
operating mode, the object has to
be within the range of 0-92 % of
the set distance.
Ԏ
If the push button is not pressed for
30 seconds during the Teach-in set-
ting, the settings made hitherto are
deleted.
ԎThe sensor can be reset to its facto-
ry setting (see »Further settings«,
Diagram1).

mation on start-up with IO-Link
are available on the Internet at

mum 32 Vdc, minimum 290 mA, in the nal in-
