﻿The brightness range, adjustable by switching or dimming procedures, can be limited by defining a lower and upper brightness value. 

The lower brightness value is either defined by the basic brightness, or alternatively, by the minimum brightness. The upper brightness value is always characterised by the maximum brightness. The maximum brightness adjustable in the ETS is never exceeded under any circumstances in the switched-on operating state of a dimming output. Neither when switching on nor when dimming. 

This parameter defines whether the adjustable brightness range at the lower limit will be limited by the basic brightness or by a minimum brightness.
