Operating Instructions
zws-15/CD/HV/QS
zws-15/CE/HV/QS
Ultrasonic proximity sensor with
one switched output
Safety advice
I
Read the operating instructions
before starting operation.
I
Connection, assembly and set-
tings only by competent techni-
cians.
I
Not a safety device in accordance
with EU machine guidelines.
Proper use
zws ultrasonic sensors are used for
non-contact detection of objects.
Mounting
I
Install sensor on the fitting place.
I
Connect cable to M8 connector.
Starting operation
I
Switch on power supply.
I
Adjustment according to dia-
gram.
Ultrasonic-Sensors
Operation
The sensor has three operation
modes
I
Operation using one switching
point
I
Window mode
I
Reflective barrier
Synchronisation
You can synchronize as many sen-
sors as you like.
I
Apply a square-wave signal to
the sync-input
pulse width t
i
> 150 µs,
repetition rate t
p
= 8 ms...1 s.
A high level on the synchro-input
will deactivate the sensor.
External synchronisation signal
Maintenance
microsonic sensors are mainte-
nance-free. In case of excess caked-
on dirt we recommend cleaning the
white sensor surface.
Checking operation mode
I
In normal mode shortly press the
pushbutton.
The green LED stops shining for one
second, then it will show the current
operating mode:
1 x flashing = operation with one
switching point
2 x flashing = window mode
3 x flashing = reflective barrier

1) Keep in mind the temperature drift of the switching point, e.g. for each change in temperature
amounting to 10° C, teach a 1.7 % higher switching point.
