Microsonic nano-15/CI - Manual

Operating instructions
Ultrasonic sensor with one
analogue output
nano-15/CI nano-15/CU
nano-24/CI nano-24/CU
Product Description
The nano sensor offers a non-contact
measurement of the distance to an
object that has to be present within
the sensor’s detection zone. Depend-
ing on the set window limits, a dis-
tance-proportional analogue signal is
output.
The window limits of the analogue
output and its characteristic can be
adjusted with the Teach-in proce-
dure.
One 2-colour LED indicates operation
and the state of the analogue
output.

Safety Notes
 Read the operating instructions
prior to start-up.
 Connection, installation and
adjustment works should be car-
ried out by expert personnel only.
 No safety component in
accordance with the EU Machine
Directive
Use for intended purpose only
nano ultrasonic sensors are used for
non-contact detection of objects.
Installation
 Mount the sensor at the installa-
tion site.
 Connect a connection cable to the
M12 device plug.
The assembly distances shown in fig.
2 for two or more sensors should not
be fallen below in order to avoid mu-
tual interference.

Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend to clean the white
sensor surface.
Notes
 Every time the power supply is
switched on, the sensor detects its
actual operating temperature and
transmits it to the internal tempe-
rature compensation. This results
in a slight correction of the ana-
logue output value after 45 se-
conds.
 If the sensor was switched off for
at least 30 minutes and after po-
wer on an object is placed in the
middle of the adjusted analogue
window for 30 minutes (the ana-
logue output value is in the range
of 11 to 13 mA or 4.4 to 5.6 V) a
new adjustment of the internal
temperature compensation to the
actual mounting conditions takes
place.
 The sensors of the nano family
have a blind zone. Within this
zone a distance measurement is
not possible.
 In the normal operating mode, an il-
luminated yellow LED signals the ob-
ject is within the adjusted window
limits.
 The sensor can be reset to its fac-
tory setting (see »Further set-
tings«).
