© 2003 ABB STOTZ-KONTAKT GmbH Gerd Schlag Folie 1 AN INTRODUCTION TO DALI
© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 2 What is DALI ? (1) The subject DALI is a synonym for a standard, independent of the manufacturer to control electronic ballast devices (ebd`s) and lamps the digital way
© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 3 This standard (DALI) is supported by the worldwide leading manufacturers of ebd`s since 1999. There is a working group ( Activity Group DALI – www.dali- ag.org) to establish the DALI Standard.www.dali- ag.org Since October 2003 ABB Stotz Kontakt is a member of AG DALI and therefore authorised to assemble and sell DALI compatible devices with DALI Logo. Members of working group AG DALI: ABB, BAG, CEAG, DELMATIC, DIAL, ECKERLE, ERC, ERCO, ETAP, GEWISS, GITRONICA, HADLER, HELVAR, HÜCO, INSTA, JOHANSON CONTROLS, LIGHTOLIER, LUTRON, LUXMATE, MAY&CHRISTE, NIKO, OSRAM, PHILIPS LIGHTING, SANDER, TRIDONIC, TROLL, UNIVERSAL LIGTHING TECHNOLOGIES, VOSSLOHGIES, VOSSLOH-SCHWABE, WILA What is DALI ?

© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 5 Task of working group DALI - worldwide adoption of DALI - Securing the convertibility of DALI devices - Support of application of DALI No Certification or Registration of DALI devices necessary DALI Logo indicates the compatibility of DALI components DALI is a stand-alone System. It is a digital control and a subsystem for lighting technology and not a bussystem Specification is documented in DIN IEC 60929 What is DALI ? (4)
© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 6 DALI is a digital interface in lighting technology, used as a subsystem in building technology It is supported by all manufacturers of electronic ballast devices (ebd`s) A standard independent of the manufacturer Specification is documented in DIN IEC 60929 DALI - the Standard for Lighting Technology
© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 7 DALI is more and more in use in non residential buildings Modern and smart Lighting technology is with DALI feasible, including coulored light For all types of lamps (e.g. halogen lamps, fluorescent lamps, bulbs, LEDs) are appropiated ballast devices available The product range of DALI components will extend on L&B 2004 DALI-Gateways for superior building installation systems like EIB / KNX, LON... are available Where is DALI today (1)
© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 8 Architects for Illumination accept DALI as ideal tool for lighting technology DALI is specified in many cases for Light moods (e.g. Doctor`s surgery) Light effects (e.g. Show rooms) Functional Light control (e.g. Office buildings) Supervision (e.g. Building with Facility-Management) Where is DALI today (2)

© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 10 DALI relates to DIN IEC 60929, which defines a digital dim interface for elektronic ballast devices (ebd`s). Standardised is: Technical items (Current, Voltage, Timing...) Data protocol Test conditions for ebd`s DALI Technology (2)

Dimming limits) Status feedback (Lamp on/off, topical Brightness value, Lamp-, ebd fault) Operation with emergency power DALI Technology (4)
© 2003 ABB STOTZ-KONTAKT GmbH G. Schlag- Folie 13 The Intelligence of DALI is not centralised. A lot of adjustments and brightness values are stored in the EBD Individual adress Assignment to groups Light scenes Speed of Dimming Switch on brightness in case of voltage recovery Brightness value in case of emergency power supply DALI Technology (5)
