Microsonic sks-15/CF/A Operating Manual

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.

Operating modes
Three operating modes are available
for the switches output:
Enable/disable Teach-in

■ 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

Further settings
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.
