Microsonic sks-15/D Operation 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.
Operation Manual Use for intended purpose only
sks ultrasonic sensors are used for

press the push-button. The green
LED stops shining for one second,
then it will show the current ope-
rating mode:
Ԏ 1x flashing = operation with one
switching point
Ԏ 2x flashing = window mode
Ԏ 3x flashing = reflective barrier
After a break of 3 s the green LED
shows the output function:
Ԏ 1x flashing = NOC
Ԏ 2x flashing = NCC
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend to clean the white
sensor surface.
Notes
Ԏ The 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.
Ԏ In the normal operating mode, an
illuminated yellow LED signals the
switching output is switched
through.
