Measuring sensor with multiple switch points

OQT120-R103-2EP-IO

4

Every taught-in switching threshold can be retaught (overwritten) by pressing the „TI“ button

again.

Pressing and holding the "TI" button for > 4 s completely deletes the taught-in value. The yellow and green LEDs go out simultaneously to

indicate that this procedure has been completed. Successful resetting is indicated by alternating flashing (2.5 Hz) of the yellow and green LEDs.

Resetting to Factory Default Settings

Press the „TI“ button for > 10 s in rotary switch position ‚O' to reset to factory default settings. The yellow and green LEDs go out simultaneously

to indicate the resetting.

Resetting process starts when the "TI" button is released and is indicated by the yellow LED. After the process the sensor works with factory

default settings, immediately.

OMT:

• Factory default settings switch signal Q1:

Switch signal active, window mode

• Factory default settings switch signal Q2:

Switch signal active, window mode

OQT:

• Factory default settings switch signal Q1:

Switch signal active, BGS mode (background suppression)

• Factory default settings switch signal Q2:

Switch signal 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.
