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 accor‐
dance 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".
Sensor with potentiometer (IO Link):
The sensitivity is adjusted with the potentiometer (type: 270°).
Clockwise rotation: to teach mode; counterclockwise rotation: to run mode.
Turn the potentiometer clockwise to teach mode until yellow LED begins blinking. Align
sender and receiver and observe lightbar for alignment quality. As long as lightbar has
a response, the system can be returned to run mode.
Turn the potentiometer counterclockwise to run mode until yellow LED stops blinking.
The yellow LED should remain lit. To verify, block lightbeam and LED will turn off.
Unblock lightbeam the LED will come on again.
We recommended setting the potentiometer to "Maximum".
Please refer to the enclosed operating instructions for the IO-Link photoelectric sensor
for information about adjusting the IO-Link sensing range.
The sensor is adjusted and ready for operation.
Alarm / Health output
The sensor (HSE18) features a pre-failure notification output ("Q2" in connection dia‐
gram [B], if the alarm option is selected), which issues a notification if the signal
strength of the light being received is not sufficient. Possible causes: Sensor is conta‐
minated, sensor is out of alignment. In the good state: LOW (U
contaminated: HIGH (>+U
