6.2.4.1 Twilight sensor activation threshold
adjustment
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). In the event
the intervention threshold (illuminator activation)
must be adjusted differently, loosen the plug on
the illuminator rear and proceed adjusting with a
screwdriver.
