Microsonic nano-15/CI Operating Manual

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. Depen-
ding 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 procedure.
A duo-LED indicates operation and the
state of the analogue output.
Proper Use
Operating Manual nano ultrasonic sensors are used for
non-contact detection of objects.

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.
Ԏ No safety component in ac-
cordance with the EU Machine
Directive, use in the area of per-
sonal and machine protection
not permitted
Installation
Mount the sensor at the installation

site.
Connect a connection cable to the
Î
M12 device plug, see Fig. 1.
The assembly distances shown in

should not be fallen below in order
to avoid mutual interference.

Notes
Ԏ Every time the power supply is swit-
ched on, the sensor detects its ac-
tual operating temperature and
≥0.25 m ≥1.30 m
transmits it to the internal tempera-
≥0.25 m ≥1.40 m
ture compensation. This results in a
slight correction of the analogue
output value after 45 seconds.
Ԏ If the sensor was switched off for at
least 30 minutes and after power
on an object is placed in the middle
of the adjusted analogue window
for 30 minutes (the analogue out-
put value is in the range of 11 to 13
mA or 4.4 to 5.6 V) a new adjust-
ment of the internal temperature
compensation to the actual moun-
ting conditions takes place.
Ԏ The sensors of the nano family have
a blind zone. Within this zone a di-
stance measurement is not possible.
Ԏ
In the normal operating mode, an
illuminated yellow LED signals the
object is within the adjusted win-
dow limits.
Ԏ The sensor can be reset to its facto-
ry setting (see »Further settings«).
