2. Window mode:

Teach in switching thresholds: you can teach in or overwrite a taught-in switching threshold at any time. To do this, press the "TI" button again.

Reset a value: you can reset a taught-in value. To do this, press the "TI" button for > 4 s, until the yellow and green LEDs go out. The reset

process itself starts when the "TI" button is released.

• Reset successful: the yellow and green LEDs flash alternately at 2.5 Hz.

Resetting to Factory Settings

To revert back to factory settings, press the "TI" button for > 10 s with the rotary switch set to position "O," until the yellow and green LEDs go out

at the same time. The reset process itself starts when the "TI" button is released.

• Reset to factory settings successful: the yellow and green LEDs light up at the same time. The sensor then continues to operate with factory

settings.

• Factory setting for switching signal Q1:

Switching signal high active, BGS mode (background suppression)

• Factory setting for switching signal Q2:

Switching signal high active, BGS mode (background suppression)

Configuring different operating modes via the IO-Link interface

The devices are equipped with an IO-Link interface as standard for diagnostics and parameterization tasks to ensure optimum

adjustment of the sensors to the relevant application. Four different operating modes can be set, among other features:

Background suppression operating mode (one switch point):

• Detection of objects irrespective of type and color in a defined detection range. Objects in the background are suppressed.

Background evaluation operating mode (one switch point):

• Detection of objects irrespective of type and color against a defined background. Reliable detection of objects at close range (detection range

>= 0 mm). The background serves as reference.

Single point mode operating mode (one switch point):

• Detection of objects irrespective of type and color in a defined detection range. Objects in the background are suppressed.

• The switch point corresponds exactly to the set point.

Window mode operating mode (two switch points):

• Detection of objects irrespective of type and color in a defined detection range. Reliable detection when object leaves the detection range.

• Window mode with two switch points.

Center window mode operating mode (one switch point):

• Detection of objects irrespective of type and color in a defined detection range. Sets a defined window around a given object. Objects outside

this window are not detected.

• Window mode with one switch point.

Two point mode operating mode (hysteresis operating mode):

• Detection of objects irrespective of type and color between a defined switch-on and switch-off point.
