Microsonic sks-15/CI 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.
Depending on the set window limits,
a distance-proportional analogue sig-
nal is output.
For sensor setting, the accessory Link-
Control adapter LCA-2 is recommen-
ded in combination with LinkControl
software for Windows
the sensor can also be adjusted by
Teach-in via Teach-in button. Two LEDs
indicate operation and the state of the

Notes

Ԏ Every time the power supply is swit-
Start
ched on, the sensor detects its ac-
tual operating temperature and
t t
transmits it to the internal tempera-
i p
ture compensation. This results in a
slight correction of the analogue
output value after 45 seconds.
Ԏ If the sensor was switched off for at
least 30 minutes and after power
on an object is placed in the middle
of the adjusted analogue window
for 30 minutes (the analogue out-
put value is in the range of 11 to
13 mA or 4.4 to 5.6 V) a new ad-
justment of the internal tempera-
ture compensation to the actual
mounting conditions takes place.
Ԏ The sks sensor has a blind zone,
within which distance measure-
ments are not possible.
Ԏ In the normal operating mode, an
illuminated orange LED signals that
the object is within the adjusted
window limits.
Ԏ If the Teach-in button is not pressed
for 30 seconds during the Teach-in
setting, the settings made hitherto
are deleted.
Ԏ The sensor can be reset to its facto-
ry setting (see »Further settings«).
