Recommended
solution
Clean the filter and protective screen with
soft cloth. If needed, replace the protec-
tive screen.
Increase the sensitivity, get closer to the
arc, do not cover the sensors and the
solar cell by hand, torch or other objects.
Increase the opening time delay.
Reduce the sensitivity, reduce the disturb-
ing ambient light sources.
Never use below -5°C.
The reaction time for the first arc only will
be 10 ms, then normally 0,4 ms.
