HL18T/G: Sensor with potentiometer:
The sensitivity is adjusted with the potentiometer (type: 270°). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced.
Adjustment for detecting transparent objects (> 10% damping): Place object betwe‐
en sensor and reflector. Reduce the sensitivity until the LED indicator goes out. On‐
ce the object is removed, the LED indicator must light up again. If the LED indicator
does not light up again, check the application conditions.
HL18T: The sensor has a continuous threshold adaptation function. 3 different
operating modes can be set based on the desired signal damping level. To do this,
align the sensor with the reflector and turn the potentiometer clockwise until the
yellow LED on the top side of the sensor starts to flash. The green LED flashes at
the start of each mode.
Mode I for PET bottles: Activates at a signal damping level > 10% (teach time: 1 ...
5 s)
Mode II for glass: Activates at a signal damping level > 18% (teach time: 5 ... 10 s)
Mode III for colored glass or non-transparent objects: Activates at a signal damping
level > 40% (teach time: > 10 s)
Once the Teach process is complete, turn the potentiometer one full rotation coun‐
terclockwise. Teach-in mode is terminated, and the yellow LED stops flashing.
The sensor is adjusted and ready for operation. Refer to graphics C and G to check
the function. If the switching output fails to behave in accordance with graphic C,
check application conditions. See section Fault diagnosis.
