DALI advantages
Users have the following options when installing DALI -ballasts in their lighting system:
• Simple wiring of control lines (no group formation, no polarity)
• Control of individual units (individual addressing) or groups (group addressing) is possible
• A simultaneous control of all units is possible at any time(built-in initial operation function) through broadcast addressing)
• No interference of data communication is to be expected due to the simple data structure
• Control device status messages (lamp fault ...), (report options: all / by group / by unit)
• Automatic search of control devices
• Simple formation of groups through ¡°flashing¡°lamps
• Logarithmic dimming behavior matching the eye¡¯s sensitivity
• Automatic and simultaneous dimming of all units when selecting a scene
• System with assigned intelligence (every unit contains amongst other things the following data: individual address, group assignment, lighting scene values, fading time ...)
• Operational tolerances of lamps can be stored as default values (for example for the purpose of energy savings maximum values can be set)
• Fading: adjustment of dimming speed
• Identification of unit type
• Options for emergency lighting can be chosen (selection of specific ballasts, dimming level)
• No need to switch on/off the external relay for the mains voltage (this is done by internal electronic components)
• Lower system cost and more functions compared to 1¨C10V-systems
