Adjusting the switching point via the teach input
The switching point of the sensor is set to 300mm or 1200mm on delivery.
By means of a simple teach event, the switching points can be individually taught to an arbitrary distance within the scanning
range with 1-point teach (static) or 2-point window-teach (static). 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 (static) 2-point window-teach (static)
1. Place object at desired switching distance. 1. First, place object at desired switching distance for switching point 1.
2. To adjust output OUT1, connect the Teach-IN input to UBfor 2…7s
(Leuze Teach Adapter: position "Teach-UB").
The current state of output OUT1 is frozen while the adjustment is made.
2. To adjust output OUT1, connect the Teach-IN input to UBfor 7…12s
(Leuze Teach Adapter: position "Teach-UB") until the yellow and green
LEDs flash alternately at 3Hz.
3. The yellow LED flashes at 3Hz and is then ON.
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 dia-
gram 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 output OUT1 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:Theminimum distance between the switching points is as follows:
scanning range of 400mm:40mm
scanning range of 1200mm:120mm
5. To complete the teach event, briefly connect the Teach-IN input to UB
again (Leuze Teach Adapter: position "Teach-UB").
The switching window was taught in.
6. 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.

Adjusting the switching function (NC/NO) via the teach input
The switching function of the sensor is preset as follows on delivery:
OUT 1: NO contact
The output function can be switched from NO contact (NO - normally open) to NC contact (NC - normally closed) and vice versa.
Leuze Teach Adapter PA1/XTSX-M12 can be used for this purpose. If the switching function is changed, the switching output is
changed to the opposite state (toggled).
Resetting to factory settings
The sensor can be reset to the factory setting (one switching point at 300 mm or 1200 mm).
Leuze Teach Adapter PA1/XTSX-M12 can be used for this purpose.
Changeover of the switching function
1. To change the switching function, connect the Teach-IN input to UBfor more than 12s (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.
Resetting to factory settings
1. When switching on the supply voltage (during Power-On), connect the Teach-IN input to UBfor > 5s (Leuze Teach Adapter position "Teach-UB").
The green and yellow LEDs flash alternately and very quickly for a brief time.
2. Disconnect the Teach-IN input from UB. The sensor was reset to the factory setting:
1 switching point at 300 mm or 1200 mm (1-point teach, static).
