detection zones
for different objects:
The dark grey areas are determined
with a thin round bar (10 mm dia.)
and indicate the typical operating range
of a sensor. In order to obtain the light grey
areas, a plate (100 x 100 mm) is introduced
into the beam spread from the side.
In doing so, the optimum angle between
plate and sensor is always employed.
This therefore indicates the maximum
detection zone of the sensor.
It is not possible to evaluate ultrasonic
reflections outside this area.

Notes
The zws sensor has a blind zone,
within which distance measure-
ments are not possible.
In the normal operating mode, an il-
luminated yellow LED signals the
switched output is switched
through.
The standard sensor has no tempe-
rature compensation.
If the object to be sensed moves
into the detection area from the
side, the switching distance should
be set 8-10 % further than the de-
sired switch point to obtain a reli-
able object detection.
If the object moves towards the
sensor (e.g. level control) the detect
point can be taught to the actual
distance at which the sensor has to
switch the output.
Fig. 4: Set the detect point for different
directions of movement of the object
In the »Two-way reflective barrier«
operating mode, the object has to
be within the range of 0-85 % of
the set distance.
If the push-button is not pressed
for 10 minutes during the teach-in
setting, the settings made hitherto
are deleted.
The sensor can be reset to its fac-
tory setting.
