Synchronisation:
In order to suppress mutual interference, the
sensor operates via one sychronised input. If
the input is unswitched, the senor operates
at an internally generated pulse rate. The
sensor can be synchronised by the super
position of the square - shaped voltage. One
synchronising pulse at the synchronisation
input enables one measuring cycle to be
completed. The pulse width must be greater
than 100 μs. The measuring cycle com-
mences with the descending flank. The state
of the switching output changes after the
switching threshold has been exceeded five
times, as determined internally by five meas-
urements. A low level
≥
1 s, or an open
synchronisation input results in normal oper-
ation of the sensor. Synchronisation cannot
take place during teaching and vice versa.
Two operating modes are possible:
1. Multiple sensors are controlled with the
same synchronising signal. The sensors
operate on the same pulse.
2. The synchronising pulses are fed cyclical-
ly to only one sensor at a time. The sen-
sors operate in multiplex mode. A high
level at the sychronisation input deacti-
vates the sensor.
To set the Switch Points:
The ultrasonic sensor is provided with a
switching output with two teachable switch
points. These are set up by applying the
supply voltage -U
bzw. +U
to the teaching
input. The supply voltage should be applied
to the teaching input for at least 1 s. During
the teaching process the LED's indicate
whether the sensor has recognised the tar-
get. The switch points A1 and A2 are taught
by voltage -U
B
and + U
B,
, respectively.
Five functions can be set:
1. Window mode, normally open function
2. Window mode, normally closed function
3. One switch point, normally open function
4. One switch point, normaly closed function
5. Detection of presence of object
