Device functions – analog output
In measurement operation, the
blue LED
displays the behavior of analog output
Analog OUT
.
Analog output Analog OUT
Note!
When setting the analog output (teach) via the teach button, one
rising characteristic curve
is always taught; with
2-point teach, independent of the selected object distances near/far. The characteristic output curve can be inverted,
however.
Adjusting the analog output via the teach button
On delivery, the characteristic output curve of the sensor is set as a rising characteristic curve with spread over the entire scanning range:
4 … 20mA or 0 … 10V corresponds to an object distance of 50 … 400mm or 150 … 1600mm, respectively.
The analog output can be set by means of 1-point teach or 2-point teach.
Note!
When setting the analog output (teach) via the teach input, one
rising characteristic curve
is always taught; with 2-point
teach, independent of the selected object distances near/far. The characteristic output curve can be inverted, however.
Selecting the output that is to be taught: OUT1 or Analog OUT
1.
Press the
teach button
for
≥ 2s
to
activate
teach mode
. The
yellow LED (OUT 1) flashes
at 1Hz.
While in this state,
output OUT 1
can be taught.
2.
To teach
output Analog OUT
,
briefly
press the
teach button
again. The
blue LED (Analog OUT)
now flashes at 1Hz.
While in this state,
output Analog OUT
can be taught.
3.
Briefly press the teach button again to toggle between outputs
OUT 1
and
Analog OUT
in this state. The flashing LED indicates
which output is ready for teaching:
yellow LED flashing = OUT 1 ready for teaching
,
blue LED flashing = Analog OUT ready for teaching.
