1-point teach of the analog output
First activate the previously described teach mode for output Analog OUT.
By selecting an object distance within the scanning range, the characteristic curve of the analog output can be adjusted.
If an object is located outside of the taught measurement range, an error signal is output. A different analog signal is output here by the
sensor for the errors "distance too close: object outside of the measurement range" and "distance too far: object outside of the
measurement range".
2-point teach of the analog output
First activate the previously described teach mode for output Analog OUT.
By selecting 2 object distances within the scanning range, the characteristic curve of the analog output can be adjusted.
If an object is located outside of the taught measurement range, an error signal is output. A different analog signal is output here by the
sensor for the errors "distance too close: object outside of the measurement range" and "distance too far: object outside of the
measurement range".
Inverting the analog output (falling/rising characteristic curve)
First activate the previously described teach mode for output Analog OUT.
The characteristic curve of the analog output can be inverted, e.g., if a falling characteristic output curve is desired.
1-point teach - rising characteristic curve
1. Place
object at desired distance for the end point of the measurement range.
Note
:
The
minimum object distance for the end of the measurement range
is as follows:
scanning range of 3500mm:
600mm
scanning range of 6000mm:
950mm
2.
To adjust analog output
Analog OUT
,
press
the
teach button
for
2 … 7s
until the
blue and green LEDs flash simultaneously at 3Hz
.
3. Release the button
. The characteristic curve with plot rising from the start of the range (50 mm or 150 mm) to the set object distance was taught in.
4.
Error-free teach: LED states acc. to "Technical data" -> "Indicators".
Faulty teach: green and blue LEDs flash at 8Hz
until an error-free teach is performed.
2-point teach - rising characteristic curve
1. Position
the object at the first desired distance (near or far).
2.
To adjust analog output
Analog OUT
,
press
the
teach button
for
7 … 12s
until the
blue and green LEDs flash alternately at 3Hz
.
3. Release the button
. The sensor remains in teach mode and the LEDs continue to flash.
4.
Then
position
the object at the second desired distance (far or near).
Note
:
the
minimum object distance between the start and end point of the measurement range
for a scanning range of 3500mm is:
350mm
for a scanning range of 6000mm is:
600mm
5. Briefly press
the
teach button
again to complete the teach event.
The characteristic curve with rising plot from the near to the far object distance was taught in.
6.
Error-free teach: LED states acc. to "Technical data" -> "Indicators".
Faulty teach: green and blue LEDs flash at 8Hz
until an error-free teach is performed.
Inverting the characteristic curve
1.
To invert the characteristic curve of the analog output
Analog OUT
,
press
the
teach button
for
> 12s
until the
blue and green LEDs flash alternately
.
2. Release the button
. The characteristic curve plot was inverted.
The
blue LED
indicates the current setting of the analog output:
ON
=

OFF
=
