Device functions and indicators

All settings on the sensor are taught-in via the Teach-IN input. Device status and switching states are indicated as follows by
means of a yellow and green LED:

Switching behavior NO contact Switching behavior NC contact

Notice!
In measurement operation, the yellow and green LED only indicate the behavior of output OUT1.
The behavior of output OUT2 is not indicated.

Adjusting the switching points via the teach input

The switching points of the sensor outputs OUT1/OUT2 are set to 400mm or 1000mm on delivery.

By means of a simple teach event, the two switching points can be individually taught to an arbitrary distance within the scanning
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.

1-point teach of output OUT1 1-point teach of output OUT2

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.

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 scan­ning 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. 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.

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 scan­ning range):
yellow LED flashes at 5Hz until an error-free teach event is performed.
Output OUT2 is inactive as long as there is a teach error.

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).

Changeover of the switching function of output OUT1 Changeover of the switching function of output OUT2

1. To change the switching function, connect input Teach-IN to UB for
2…7s (Leuze teach adapter: position "Teach-UB").
The current state of output OUT1 is frozen while the adjustment is made.

2. The green and yellow LEDs flash alternately at 2Hz.

The switching function was changed over.
The switching behavior corresponds to the diagram shown above.

Notice!
Please note that the switching point is taught when GND is connected and the output function is reversed when

is connected. If no sensor action is desired, pin 2 must remain unconnected!
