Adjusting the switching points (teach) via the teach input
The switching points of the sensor outputs OUT1/OUT2 are set to 3000mm or 6000mm on delivery.
By means of a simple teach event, the two switching points can be individually taught to an arbitrary distance within the operating
range. The Leuze PA1/XTSX-M12 Teach Adapter can be used for this purpose. The adapter can also be used to easily switch the
output function from NO contact to NC contact.
Note!
Please note that the switching point is taught when GND is connected and the output function is reversed when UB is
connected. If no sensor action is desired, pin 2 must remain unconnected!
The 2-point window-teach can be configured either with the control buttons or via the IO-Link interface. Adjustment via
the teach input is not possible.
Adjusting the switching function (NC/NO) via the teach input
The switching function of both sensor outputs is set to normally open (NO) on delivery.
If the switching function is changed, the switching output is changed to the opposite state (toggled).

1.Place object at desired switching distance. 1.Place object at desired switching distance.
2.For the adjustment of OUT1, connect input Teach-IN to GND
for 2 … 7s (Leuze teach adapter: position "Teach-GND").
The current state of output OUT1 is frozen during the teach
event.
2.For the adjustment of output OUT2, connect input Teach-IN to
GND for 7 … 12s (Leuze teach adapter: position "Teach-
GND").
The current state of output OUT2 is frozen during the teach
event.
3.The yellow LED flashes at 3Hz and is then ON.
The current object distance has been taught as the new
switching point.

4.Error-free teach: switching behavior according 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.
Output OUT1 is inactive as long as there is a teach error.

2.The green and yellow LEDs flash alternately at 2Hz.
The switching function was changed over.
The switching behavior corresponds to the diagram shown
