Teach-in procedure for 1 point teach (normal):
1. Adjust the sensor to the object to be detected and make sure that the blue
teach LED is on.
2. Touch the blue teach LED at the back of the housing with a ferromagnetic tool
for longer than 2 seconds, but shorter than 4 seconds, until all 3 LEDs flash at 1Hz.
The blue LED lights up more strongly as soon as a tool is detected.
3. Touch the blue teach LED again quickly with a ferromagnetic tool to confirm the
position of the object.
4. If the sensor is to operate as a normally closed contact (output switched off when
object is detected), touch the blue teach LED again quickly with a ferromagnetic
tool within 4 seconds, otherwise the device operates as a normally open contact.
During this time, all 3 LEDs flash slowly (1Hz).
5. As soon as the blue LED lights up, the teaching process is completed.
Teach-in procedure for 2-point teach (for objects close to the background):
1. Adjust the sensor to the object to be detected and make sure that
the blue teach LED is on.
2. Touch the blue teach LED at the back of the housing with a ferromagnetic tool for
longer than 4 seconds, but shorter than 6 seconds, until all 3 LEDs flash at 2Hz.
The blue LED is on more strongly as soon as a tool is detected.
3. Touch the blue teach LED again quickly with a ferromagnetic tool to confirm
the position of the object.
4. Remove the object from the detection range and touch the blue teach LED
quickly to teach the background.
5. As soon as the blue LED is on, the teaching process is completed.
If all 3 LEDs are blinking fast (8Hz), the teach process has failed and must be repeated.
Note: The yellow LED signals whether an object is detected and does not necessarily correspond to the state of the
switching output.. The teach-in function locks 5min after switching on! The teach-in process works both with
a ferromagnetic tool and via pin 2 of the M12 connector (white wire) by connecting it to the operating volt-
age (+Ub).
Reset to factory setting
Touch the blue teach LED at the back of the housing with a ferromagnetic tool for approx.
6 seconds until all 3 LEDs are blinking fast (4Hz) and pull the tool away immediately after the
blinking frequency has set in. Afterwards, the blue teach LED should be on continuously again
and the sensor returns to the delivery settings.
