The illuminator has an integrated twilight sensor that
allows its automatic activation and deactivation at
predefined luminous conditions.
The twilight sensor is set in the factory at a
predetermined luminous level, suitable for most
installations (approximately 50lx). If you want to
adjust in different ways the threshold, loosen the
plug on the illuminator rear and proceed for the
adjustment with a screwdriver.
By rotating the trimmer clockwise, the night mode
changeover is anticipated (at a greater luminous
value). By rotating the trimmer anti-clockwise,
the night mode changeover is delayed (at a lower
luminous value).
