Microsonic lcs+340/F - Manual

Operating Instructions
Ultrasonic proximity switch with
one switched output and IO-Link
interface
lcs+340/F
lcs+600/F
Product description
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 switched output is set condi-
tional upon the adjusted detect dis-
tance.
Via the Teach-in procedure, the de-
tect distance and operating mode
can be adjusted. One LED indicates
operation and the state of the swit-
ched output.
The lcs+ sensors are IO-Link-capable
in accordance with IO-Link specifica-
tion V1.0.
Safety instructions
Read the operating instructions
prior to start-up.

Use for intended purpose only
lcs+ ultrasonic sensors are used for
non-contact detection of objects.
Installation
Mount the sensor at the place of
fitting.
Connect a connection cable to the
M12 device plug.
Start-up
Connect the power supply.
Carry out sensor adjustment in
accordance with the diagram.

Operation with one detect point
The switched output is set when the
object falls below the set detect
point.
Window mode
The switched output is set when the
object is within the set window.
Two-way reflective barrier
The switched output is set when the
object is between sensor and fixed
reflector.

Synchronisation
If under multiple sensor operation
the assembly distance falls below the
values shown in Fig. 2, the internal
synchronisation should be used. For
this purpose interconnect each pin 5
of max. 10 sensors.
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface.
Notes
The sensors of the lcs+ family have
a blind zone, within which a dis-
tance measurement is not possi-
ble.
The lcs+ sensors are equipped
with an internal temperature com-
pensation. Due to the sensors self
heating, the temperature compen-
sation reaches its optimum work-
ing-point after approx. 30 minutes
of operation.
In the normal operating mode, an il-
luminated yellow LED signals that the
switched output is switched
through.
The lcs+ sensors have a push-pull
switched output.
In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.
In the »Set detect point – method
A« Teach-in procedure the actual
distance to the object is taught to
the sensor as the detect point. If
the object moves towards the
sensor (e.g. with level control) then
the taught distance is the level at
which the sensor 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 % fur-
ther than the actual measured dis-
tance to the object. This ensures a
reliable switching distance even if
the height of the objects varies
slightly.
