Sensitivity setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
Refer to graphic to check the function. If the switching output fails to behave in accord‐
ance with graphic, check application conditions. See section Fault diagnosis.
Sensor with potentiometer (without IO Link):
The sensitivity is adjusted with the potentiometer (type: 270°). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced. We
recommend setting the potentiometer to "Maximum". A lower operating reserve may be
necessary for depolarizing surfaces, very small objects, or translucent objects.
HL18T: Clear material sensor with standard potentiometer sensitivity adjustment:
Adjustment for detecting transparent objects (> 10 % damping): Place object between
sensor and reflector. Reduce sensitivity (turn potentiometer (type: 270° counterclock‐
wise) until the yellow signal LED on top and back of the sensor is off. If the sensor
equipped with a signal strength light bar, only red LEDs on the light bar should be
illuminated.
Remove the transparent object. If the yellow signal LED is illuminated the setup is
complete. If the sensor is equipped with a signal strength light bar the yellow and
possibly some green LEDs will be illuminated.
If the yellow signal LED does not illuminate when the transparent object is removed,
check the alignment and application conditions.
HL18G: Clear material sensor with teach and AutoAdapt sensitivity adjustment:
Clockwise rotation past half the available rotation will initiate the teach process. Coun‐
terclockwise rotation below half the available rotation will complete the teach procedure
and return the sensor to run mode.
There are three teach modes:
