ROTECTION FROM LIGHT RADIATION
It is necessary to avoid sources of light or infrared radiation extraneous to the process (light-bulbs,
windows, reflections from the rolled product, etc.) that might be within the observation field of the
detector.
Correct installation shown in fig. 10: the observation field of ID2202 is from top to down, while a screen
protects it from external light sources.
Incorrect installation shown in fig. 11:
the observation field of ID2202 is from down to top (non opportune)
light sources affect the ID2202, thus increasing the risk of incorrect detection.
