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!
1.
Hold down the teach button (2to7s) until the
yellow and green LEDs flash simultaneously.
1.
Hold down the teach button (7to12s) until the
yellow and green LEDs flash alternately.
2. Release teach button – ready. 2. Release teach button – ready.
The sensor switches when approx. half of the light beam
is covered by the object.
Unlike the standard teach mode, the sensor switches
when a considerably smaller part of the light spot is
covered.
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).
1.
Hold down the teach button (2to7s) until the
yellow and green LEDs flash simultaneously.
1.
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.
