Sensor adjustment (teach) via teach button
Teach for 11% sensor sensitivity (highly transparent bottles and foils with thickness > 20μm)
 Press teach button until both LEDs flash
simultaneously
.
 Release teach button.
 Ready.
After the teaching, the sensor switches
when about 11% of the light beam are
covered by the object.

 The sensor is factory-adjusted for maximum
operating range.
Recommendation: teach only if the desired objects are not
reliably detected.
 Prior to teaching:
Clear the light path to the reflector!
The device setting is stored in a fail-safe way. A reconfiguration
following voltage interruption or switch-off is thus not required.
