Microsonic lcs+340/IU - Manual

Operating Instructions
Ultrasonic sensor with one
analogue output
lcs+340/IU
lcs+600/IU
Product description
The lcs+ sensor offers a non-contact
measurement of the distance to an ob-
ject that has to be present within the
sensor’s detection zone. Depending on
the set window limits, a distance-pro-
portional analogue signal is output.
The window limits of the analogue
output and its characteristic can be
adjusted with the Teach-in procedure.
One 2-colour LED indicates the state
of the analogue output.
The sensor automatically detects the
load put to the analogue output and
switches to current output or voltage
output respectively.
Optionally all Teach-in and additional
sensor parameter settings can be
made using the LinkControl Adapter
LCA-2 (optional accessory) and the
LinkContol software for windows.

Safety instructions
 Read the operating instructions
prior to start-up.
 Connection, installation and ad-
justments may only be carried out
by qualified staff.
 No safety component in
accordance with the EU Machine
Directive
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.

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 maximum 10 sensors to be syn-
chronised.

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.
 The load put to the analogue out-
put is detected automatically
when turning power supply on.
 If an object is within the set
window margins of the analogue
output, then LED D1 lights up
green, if the object is outside the
window margins, then LED D1
lights up red.
 If no push-buttons are pressed for
20 seconds during parameter set-
ting mode the made changes are
stored and the sensor returns to
normal mode operation.
 The sensor can be reset to its fac-
tory setting (see »Sensor adjust-
ment with Teach-in procedure«).
 Optionally all Teach-in and addi-
tional sensor parameter settings
can be made using the LinkCon-
trol adapter (optional accessory)
and the LinkControl software for
windows.
