Adjusting the switching points via the teach button
The switching point of the sensor is set to 400 mm or 1600mm (static 1-point teach) on delivery.
By means of a simple operating procedure, the switching point for the output OUT1 can be individually taught to an arbitrary distance
within the scanning range with 1-point teach (static) or 2-point window-teach (static).
Moreover, the output function can be switched from NO contact (NO - normally open) to NC contact (NC - normally closed).
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.
Teaching output OUT 1
First activate the previously described teach mode for output OUT 1.

1) See table "Switching behavior with 2-point window-teach as a function of the switching function"
1. Place
object at desired switching distance.
1.
First,
place
object at desired switching distance for
switching point 1
.
2.
To adjust the output
OUT1
,
press
the
teach button
for
2 … 7s
until the
yellow LED flashes at 3Hz
.
2.
To adjust the output
OUT1
,
press
the
teach button
for
7 … 12s
until the
yellow and green LEDs flash alternately at 3Hz
.
3. Release
the
teach button
to complete the teach event.
The current object distance has been taught as the new switching point.
3. Release the button
. The sensor remains in teach mode and the LEDs
continue to flash.
4.
Error-free teach:
LED
states and switching behavior according to the
diagram shown above.
Faulty teach
(object may be too close or too far away – please note scan-
ning range)
:
green and yellow LEDs flash at 8Hz
until an error-free teach event is
performed.
The affected output is inactive as long as there is a teaching error.
4.
Then,
place
the object at the desired switching distance for
switching
point 2
.
Note
:
The
minimum distance between the switching points
is as follows:
scanning range of 400mm:
40mm
scanning range of 1600mm:
160mm
5. Briefly press
the
teach button
again to complete the teach event.
The switching window was taught in.

Faulty teach
(object may be too close or too far away – please note scan-
ning range)
:
green and yellow LEDs flash at 8Hz
