Adjustment of the switching points (Teach) using the control buttons
The two switching points of the sensor are both set to 3000mm 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 operating 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). A
button is permanently assigned to each output for the setting (see dimensioned drawing).
Note!
All operating functions are identical for outputs OUT1 and OUT2.
Adjusting the switching function (NO/NC) using the control buttons
The control buttons can be used to switch the output function from NO contact to NC contact (or vice versa).
To do this, proceed as follows:
Note!
For 2-point window-teach, the switching behavior is dependent on the selected object distances for switching points 1
and 2. See previous page!

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 output OUT1, press button 1, to adjust output
OUT2, press button 2 for 2 … 7s until the yellow LED flashes
at 3Hz.
2.To adjust output OUT1, press button 1, to adjust output
OUT2, press button 2 for 7 … 12s until the yellow and green
LED 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 accord
-
ing to the diagram shown above.
Faulty teach (object may be too close or too far away – please
note operating range):
yellow LED flashes at 5Hz until an error-free teach event is
performed.
The affected output is inactive as long as there is a teach
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
range of 3000mm:
250mm
range of 6000mm:
500mm
5.Briefly press the teach button again to complete the teach
event.
The switching window was taught in.
6.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 operating range):
green and yellow LEDs flash at 8Hz until an error-free teach
event is performed.

Changeover of the switching function:
Switching outputs OUT1 and OUT2 are set as NO contact
ex works. If the switching function is changed, the
respective switching output is changed to the opposite state
(toggled).
Press the button for the desired
switching output for longer than
12s.
Both LEDs flash alternately for a
short time at 3Hz.
If the yellow LED is then ON,
the output functions as an NO
contact.
If the yellow LED is then OFF,
the output functions as an NC
contact.
