Product Description
The zws sensor offers a non-contact
measurement of the distance to an
object which must be positioned
within the sensor’s detection zone. In
dependence of the set window limits,
a distance-proportional analogue sig-
nal is output.
Via the push-button, the window li
-
mits of the analogue output and its
characteristic can be adjusted (Teach-
in). Two LEDs indicate operation and
the state of the analogue output.
Safety Notes
Ԏ
Read the operating instructions
prior to start-up.
ԎConnection, installation and ad-
justment works may only be car-
ried out by expert personnel.
Ԏ
No safety component in ac-
cordance with the EU Machine
Directive
Use for intended purpose only
zws ultrasonic sensors are used for
non-contact detection of objects.
Installation
Î
Mount the sensor at the installation
site with the aid of the enclosed
mounting plate (see Fig. 1). Maxi-
mum torque of attachment screw:
0,5 Nm
ÎConnect a connection cable to the
M8 device plug (see Fig. 2).
ÎAvoid mechanical load on the con-
nector.
Start-Up
ÎConnect the power supply.
Î
Carry out the adjustment in ac-
cordance with Diagram 1.

Synchronisation
You can synchronise as many sensors
as you like.
ÎApply a square-wave signal to the
sync-input with pulse width ti and
repetition rate tp (Fig. 3 and techni-
cal data).
A high level on the sync-input will
disable the sensor.

Checking operation mode
Î
In normal operating mode shortly
press the push-button. The green
LED stops shining for one second,
then it will show the current cha-
racteristic of the analogue out-
put:
Ԏ1x flashing = rising
Ԏ2x flashing = falling
Maintenance
microsonic sensors are maintenance-
free. In case of excess caked-on dirt
we recommend cleaning the white
sensor surface.
Notes
Ԏ
Every time the power supply is swit-
ched on, the sensor detects its ac-
tual operating temperature and
transmits it to the internal tempera
-
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 ad-
justment of the internal tempera-
ture compensation to the actual
mounting conditions takes place.
Ԏ
The zws sensor has a blind zone,
within which distance measure-
ments are not possible.
ԎIn the normal operating mode, an
illuminated yellow LED signals the
object is within the adjusted win-
dow limits.
Ԏ
If the push-button is not pressed for
30 seconds during the teach-in set-
ting, the settings made hitherto are
deleted.
ԎThe sensor can be reset to its facto-
ry setting (see »Further settings«,
Diagram 1).

detection zones
for different objects:
The dark grey areas represent the
zone where it is easy to recognise
the normal reflector (round bar).
This indicates the typical opera-
ting range of the sensors. The
light grey areas represent the
zone where a very large reflector
– for instance a plate – can still
be recognised. The requirement
here is for an optimum alignment
to the sensor. It is not possible to
evaluate ultrasonic reflections
outside this area.
