Microsonic sks-15/D User 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 switching output is set in depen-
dence of the adjusted detect distance.
Via the push-button, the detect dis-
tance and operating mode can be
adjusted (Teach-in).
Two LEDs indicate operation and the
state of the switching output.
The output function is changeable
from NOC to NCC.
Use for intended purpose only
sks ultrasonic sensors are used for
non-contact detection of objects.

Start-Up
ÎConnect the power supply.
Î
Set the sensor parameters using the
Teach-in procedure, see Diagram1.
Factory Setting
sks sensors are delivered with the fol-
lowing settings:
Ԏ
Operation with one switching point
Ԏ
Switching output on NOC
Ԏ
Switching point at operating range
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 outside 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
ԎThe sensors with internal tempera-
ture compensation (sks-15/CD and
sks-15/CE) determine their current
operating temperature each time
the operating voltage is switched
on and pass this value on to the in-
ternal temperature compensation.
After 45 seconds, the internal tem-
perature compensation adjusts to
its adjusted value.
Ԏ
sks-15/CD and sks-15/CE sensors
have internal temperature compen-
sation. Because the sensors heat up
on their own, the temperature com-
pensation reaches its optimum wor-
king point after approximatly 30
minutes of operation.The sensors
sks-15/D and sks-15/E have no tem-
perature compensation.
Ԏ
The sks sensor has a blind zone,
within which distance measure-
ments are not possible.
ԎIn the normal operating mode, an
illuminated yellow LED signals the
switching output is switched
through.

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.

Ԏ
If the object moves towards the
sensor (e.g. level control) the swit-
ching point can be taught to the
actual distance at which the sensor
has to switch the output.
If the object to be scanned moves
into the detection area from the
side, the switching distance should
be set 8-10 % further than the ac-
tual measured distance to the ob-
ject. This ensures a reliable swit-
ching 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 0-85 % of
the set distance.
Ԏ
If the Teach-in button is not pressed
for 30 seconds during the Teach-in
setting, the settings made hitherto
are deleted.
ԎThe sensor can be reset to its facto-
ry setting (see »Further settings«,
Diagram1).
