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. 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
U
B
for
2 … 7s
(Leuze Teach Adapter: position "Teach-U
B
").
The current state of output
OUT1
is frozen while the adjustment is made.
2.
To adjust output
OUT1
,
connect
the
Teach-IN
input to
U
B
for
7 … 12s
(Leuze Teach Adapter: position "Teach-U
B
") 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
:
The
minimum 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
U
B
again (Leuze Teach Adapter: position "Teach-U
B
").
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.
