Microsonic lcs-25/DDD/QP Operating Manual

Product Description
Ԏ The lcs-sensor offers a non-contact
measurement of the distance to an
object which must be positioned
within the sensor's detection zone.
The switching outputs are set con-
ditional upon the adjusted detect
distances.
Ԏ The output functions are adjustable
from NOC to NCC.
Ԏ Three-colour LEDs indicate the swit-
ching status.
Ԏ The sensor can be set via Teach-in
procedure.
Ԏ Optionally all Teach-in and additio-

Safety Notes
Ԏ Read the operating manual prior
to start-up.
Ԏ Connection, installation and ad-
justment works should be carried
out by expert personnel only.

Proper Use
lcs ultrasonic sensors are used for non-
contact detection of objects.
The lcs-sensors have a blind zone in
which distance measurement is not
possible. The operating range indi-
cates the distance of the sensor that
.
®
can be applied with normal reflectors
with sufficient function reserve. When
using good reflectors, such as a calm
water surface, the sensor can also be
used up to its maximum range. Ob-
jects that strongly absorb (e.g. plastic
foam) or diffusely reflect sound (e.g.
pebble stones) can also reduce the
defined operating range.

Notes
Ԏ lcs-sensors have internal tempera-
ture compensation. Because the
sensors heat up on their own, the
temperature compensation reaches
its optimum working point after
approx. 30 minutes of operation.
Ԏ In the normal operating mode, an
illuminated yellow LED signals that
the corresponding switching output
is set.
Ԏ During Teach-in procedure, the hys-
teresis loops are set back to factory
settings.
Ԏ If no signal is generated at the Com
input for 20 seconds during the
Teach-in procedure, the settings
made up to that point are stored
and the sensor returns to normal
operating mode.
Ԏ The sensor can be reset to its facto-
ry setting (see Diagram 3).
