Maintenance
microsonic sensors are mainte-
nance-free. In case of excess caked-
on dirt we recommend cleaning the
white sensor surface.
Checking operation mode
In normal mode shortly press the
I
pushbutton.
The green LED stops shining for one
second, then it will show the current
operating mode:
1 x flashing = operation with one
switching point
2 x flashing = window mode
3 x flashing = reflective barrier

1) Keep in mind the temperature drift of the switching point, e.g. for each change in temperature
amounting to 10° C, teach a 1.7 % higher switching point.
After a break of 3 s the green LED
shows the output function:
1 x flashing = make function
2 x flashing = brake function
