Microsonic nano-15/CD - Manual

Operating Instructions
Ultrasonic proximity switch with
one switched output
nano-15/CD nano-15/CE
nano-24/CD nano-24/CE
Product description
The nano 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 2-colour LED
indicates operation and the state of
the switched 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.

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.
Start-up
 Connect the power supply.
 Carry out sensor adjustment in
accordance with the diagram.

Operating modes
Three operating modes are available
for the switched output:
 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.
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning 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 the switched output is not
set for 30 minutes a new adjust-
ment of the internal temperature
compensation to the actual moun-
ting 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 that the
switched output is switched
through.
 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.
