Operating manual
sks-15/CF/A
Ultrasonic proximity switch
with one switching output and
IO-Link interface
Product description
The sks sensor offers a non-contact-
measurement of the distance to an
object which must be positioned
within the sensor's detection zone.
The switched output is set in depen-
dance of the adjusted detect distan-
ce.
Via the push-button, the distance
and operating mode can be adjusted
(Teach-in). Two LEDs indicate operati-
on and the state of the switched
output. The output function is chan-
geable from NOC to NCC.
IO-Link
The sks sensor is IO-Link-capable in
accordance with IO-Link specification
V1.1 and supports Smart Sensor Pro-
file like Digital Measuring Sensor.
Safety notes
■
Read operating instructions pior to
start-up.
■
Connection, installation and ad-
justment works may only be
carried out by expert personnel
■
No safety component according to
EU Machinery Directive
Proper use
sks ultrasonic sensors are used for
non-contact detection of objects.
Mounting
■
Mount the sensor at installation
site, Maximum torque: 0.5 Nm
■
Connect a connection cable to the
M8 device plug

■
Operation with one switching point
The switched output is set if the ob-
ject falls below the set detect point.
■
Window mode
The switched output is set if the object
is outside the set window margins.
■
Two-way reflective barrier
The switched output is set if the ob-
ject is located between the sensor
and reflector.
Checking operation mode
■
In normal mode shortly press the
push-button.
The green LED stops shining for one
second, then it will show the current
operating mode:
1 x flashing = operation with one
switching point
2 x flashing = window mode
3 x flashing = reflective barrier
After a break of three seconds, the
green LED shows the
output func-
tion
:
1 x flashing = NOC
2 x flashing = NCC
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface.
Notes
■
Every time the power supply is swit-
ched on, the sensor detects its actu-
al operating temperature and trans-
mits it to the internal temperature
compensation. The adjusted value is
taken over after 45 seconds.
■
If the sensor was switched off for
at least 30 minutes and after po-
wer on the the switched output is
not set for 30 minutes a new ad-
justment of the internal tempera-
ture compensation to the actual
mounting conditions takes place.
■
The sks sensor has a blind zone
whithin which distance measure-
ments are not possible.
■
In the normal operating mode, an
illuminated yellow LED signals the
switched output is switched
through.
■
In the »Set detect point – method A«
Teach-in procedure the actual dis-
tance to the object is taught to the
sensor as the detect point. If the ob-
ject moves towards the sensor (e.g.
with level control) then the taught
distance is the level at which the sen-
sor has to switch the output.
■
If the object to be scanned moves
into the detection area from the
side, the »Set detect point +8 % –
method B« Teach-in procedure
should be used. In this way the
switching distance is set 8 %
further than the actual measured
distance to the object. This ensu-
res a reliable switching distance
even if the height of the objects
varies slightly, see fig. 2.
■
In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.
