* The sensitivity can also be set in exactly the same way using the programming wire (pin
2 / WH). To activate the functions the programming wire is connected for the appropriate
time to L+ (pin 1 / BN) for PNP units or to L- (pin 3 / BU) for NPN units. Feedback: If set-
ting was not successful via the programming wire, the output will switch for 2s. The unit
then reverts to the operating mode with the sensitivity unchanged.
If the setting of the sensitivity is not possible (e.g. object signal
and background signal are about the same), the red LED flashes
after step 3 for approx. 2s. The unit then passes into the operat-
ing mode with the sensitivity being unchanged.
If the setting button is not activated for 15 minutes during the
programming process, the unit passes automatically into the
operating mode with the sensitivity being unchanged.
Setting of the maximum sensitivity*
• Go into the programming mode (step 1).
• Align the unit so that no light is reflected.
• Press the setting button twice (see steps 2 and 3).
* The maximum sensitivity can also be set in exactly the same way using the program-
ming wire (pin 2 / WH). To activate the functions the programming wire is connected for
the appropriate time to L+ (pin 1 / BN) for PNP units or to L- (pin 3 / BU) for NPN units.

Press once.
The yellow and green LEDs go out for approx. 1s,
after approx. 3s the green LED is on.
The unit is in the operating mode.

Allow objects to pass through the detection area during the measure-
ment (about 1s) (number of the objects between min. 8Hz and max.
switching frequency).
