Sensor adjustment (teach) via teach button

The sensor is factory-adjusted for maximum operating range. The teach procedure is only necessary if the sensor does not switch when

an object enters the light beam.

 Standard teach (low sensitivity)  Sensitive teach (increased sensitivity)

Clear the light path before teaching!

Hold down the teach button (2to7s) until the

yellow and green LEDs flash simultaneously.

Hold down the teach button (7to12s) until the

yellow and green LEDs flash alternately.

2. Release teach button – ready. 2. Release teach button – ready.

After teaching for normal sensor sensitivity, the sensor

switches for objects with a

minimum size of 1mm

(see table under "General Information").

After teaching for increased sensor sensitivity, the sensor

switches for objects with a

minimum size of 0.1 … 0.2mm

(see table under "General Information").

If both LEDs flash rapidly after the teach event, a teaching error has happened. Please check the alignment of the light beam

onto the reflector and carry out another teach event.

Device settings are stored fail-safe.

 Teach at max. operating range (factory setting)  Set switching behavior (light/dark switching)

Obstruct the light path before teaching!

When the function is activated, the switching output is always

inverted relative to the previously set state (toggle function).

Hold down the teach button (2to7s) until the

yellow and green LEDs flash simultaneously.

Hold down the teach button longer than 12s until

only the green LED flashes.

LED ON: Switching output now light switching

(Output active if light path is free)

LED OFF: Switching output now dark switching

(Output active if there is an object in the light path)

2. Release teach button – ready. 2. Release teach button – ready.

The sensor now operates with the maximum function

reserve/operating range.

Note: The yellow LED is not dependent on the switching

behavior setting and always indicates light switching in

normal operation.

Device settings are stored fail-safe.
