Adjusting the switching points via the teach button
The switching points of the sensor for both outputs are set to 3500mm or 6000mm (static 1-point teach) on delivery.
By means of a simple operating procedure, the switching points for each output 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). An
LED is permanently assigned to each output for the setting.
Selecting the output that is to be taught: OUT1 or OUT2
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 OUT 2, briefly press the teach button again. The blue LED (OUT 2) now flashes at 1Hz.
While in this state, output OUT 2 can be taught.
3.Briefly press the teach button again to toggle between outputs OUT 1 and OUT 2 in this state. The flashing LED indicates which
output is ready for teaching:
yellow LED flashing = OUT 1 ready for teaching,
blue LED flashing = OUT 2 ready for teaching.
Teaching output OUT 1 or OUT 2
First activate the previously described teach mode for output OUT 1 or OUT 2.

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 selected output, press the teach button for
2 … 7s until the yellow LED (OUT 1) or blue LED (OUT 2)
flashes at 3Hz.
The current state of the selected output is frozen during the
adjustment process.
2.To adjust the selected output, press the teach button for
7 … 12s until the yellow (blue) and green LEDs flash alter
-
nately at 3Hz.
3.Release the button.
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 accord
-
ing to the diagram shown above.
Faulty teach (object may be too close or too far away – please
note scanning range):
green and yellow (blue) LEDs flash at 8Hz until an error-free
teach event is performed.
The selected 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 3500mm: 350mm
scanning range of 6000mm: 600mm
5.Briefly press the teach button again to complete the teach
event.
The switching window for the selected output was taught in.

Faulty teach (object may be too close or too far away – please
note scanning range):
green and yellow (blue) LEDs flash at 8Hz until an error-free
teach event is performed.
