DALI – What, Where & Why?
3
• DALI replaces analogue 1-10V as well as digital DSI control technology and surpasses them in terms of
flexibility and individuality. DALI can be used as autonomous light management system, as well as
connected to building automation systems
• . Now days we see DALI in all projects, its well known, its standardized, and easy for lighting manufactures
to ensure correct dimming and control of their fittings
• Recently, advancements in DALI can control colour – Human centric lighting, exit and emergency test and
supervision, as well as fault and maintenance monitoring, and even wireless protocol
• DALI - Digital addressable lighting interface, is an open and now standardized, digital communication technology for
control of primarily, lighting devices ( ballast ) to interact with input devices ( sensors and switches ) and other control
systems ( KNX ) .
• It’s a smart and flexible way to control lights, through a 2-wire bus
• The DALI Alliance (also known as the Digital Illumination Interface Alliance, or DiiA) is the global industry organization for
DALI lighting control.
• DALI originally was introduced in commercial building, as a cheap and economic way for retro fitting offices lighting. Whereby the
lights could generally stay in position and wall would move to cater for the changes by the tenants, this was a great advancement for
lowering cost, as now no more rewiring, just a programmer re grouping of lights to suit
• In the late 1990 to develop a better digital lighting technology to meet the needs of the lighting market, Tridonic and other well-
known Euro well-known equipment manufacturers Helvar, Osram, Philips and other well-known lighting have jointly developed the
digital addressable lighting interface protocol (DALI)

Topology: rules for wiring and power supply’s
• 2 wire bus system
• Wiring can be any topology:
• Star
• Daisy chain (Bus)
• Combination
• Ring is discouraged.
• cable length of up to 300m (1.5mm2 wire cross
section), as a result of the maximum voltage drop of
2V on the DALI-line and the system current
• Dali needs a power supply –
• DALI bus voltage: 12V-22.5V (typical 16V)
• DALI system current: Max <250mA
• Low Speed - data transfer speed: 1200Baud or 1.2Kbs
• Non polarity conscious

Design networks
• Up to 64 addressable DALI operating devices (recommended no more than 50 - 55 devices per
network, this leaves room for future requirements, and mitigate and speed issue for the bus )
• 16 DALI groups
• 16 DALI scenes
• Requires a master or multi master
• Take into consideration –
• Size of the area and required equipment
• Function and require features ( device types - tuneable white, RGBW,
fault reporting DALI or DALI 2 )( DALI 1 can run on DALI 2 but in the other
way around )
• Gateways or system connecting too
• Exit and emergency’s and testing
• Sensors or inputs
• Trade mark, certified equipment product data base https://www.dali-

  • 7. www.ivoryegg.com Commissioning / testing / trouble shooting • Control gear may draw up to 2 mA from DALI. Careful: Some Control Gear draws more! Check your products! (This means those devices do not comply with the standard) • Double address – When you have multiple circuits feeding a DALI universe, getting turn off when auto address commissioning. You need to reset the ballast, depending on the commissioning software Or remove it and change the existing address. • Default device configuration of ballast - 100% lights on when no DALI comms available • Is the wiring correct – no loops • Is the voltage correct? • Is there mixed DALI universes? • Can you send a broadcast command ( masters with broadcast functionality ) • Commissioning and testing software is connected to the DALI bus to a testing device, usually a PC 7
  • 8. www.ivoryegg.com Working with other systems If we consider DALI to be a way to talk to light fitting, then we really need to look at control systems that work with DALI to achieve control in buildings. Some of the system and protocols we find in buildings generally have a interface and gateway to interact with a DALI system. A lot of the manufacturers of the systems, including KNX are members of both: KNX and DALI associations, and a lot of thought into how best the system compliment each other and work together. Generally the each manufacture has a DALI commission and testing tool, Some tools are product specific and others are generic. Its advised that specific tools are used where available. If your using generic tools in conjunction with specific tool, its best suggested that you know the idiosyncrasies of each to mitigate problems. Some of the more popular KNX and generic tools are : • ABB I-bus tool – Advantage of using the KNX bus to connect, can be remote • Theben ETS plug in - – Advantage of using the KNX bus to connect, can be remote • Rapix tool - Advantage of using smart device to commission • Master configurator – original, in depth information available Lets have a live look 8
  • 9. www.ivoryegg.com Dali device types 9 Part Type of control gear Device type number 201 Fluorescent lamp control gear Device Type 0 (DT0) 202 Self-contained emergency control gear Device Type 1 (DT1) 203 Discharge (HID) lamp control gear Device Type 2 (DT2) 204 Low-voltage halogen lamp control gear Device Type 3 (DT3) 205 Incandescent lamp dimmer Device Type 4 (DT4) 206 Conversion to D.C. voltage (1-10V, 0-10V converter) Device Type 5 (DT5) 207 LED lamp control gear Device Type 6 (DT6) 208 Switching (relay) control gear Device Type 7 (DT7) 209 Colour control gear Device Type 8 (DT8) It’s important to understand that there are different DALI device types. These device types are expressed through the standard, and they specify what functionality the DALI devices have. It’s critical when you’re designing or commissioning DALI network that you have compatibility and support for these device types from controllers, gateways, ballasts, sensors and switches. If a device is truly compatible, they will require to have the trademark logo, with supporting documentation on what DALI types are supported. Remember the logo and data base are you guarantee these have been tested to the standard. Those inferior product without don’t and are usually the culprit with problems
  • 10. www.ivoryegg.com The DALI standard 10 DALI-2 and IEC 62386 DALI is an industry-standardized protocol, and is specified in the multi-part international standard IEC 62386, as well as by new specifications written by DiiA. DALI-2 is the certification program which is based on the latest version of the DALI protocol, and is developed and maintained by the DALI Alliance. The IEC 62386 standard was restructured in late 2014 for ease of use and to faciliate the development of DALI-2. Many improvements were made to the standard including the addition of new commands and features. One of the most significant changes was the addition of control devices(including application controllers and input devices), which were not included at all in the original version of the standard. DALI-2 also includes much more comprehensive testing than DALI version-1, with a strong focus on device interoperability. DALI-2 test results are independently verified by the DALI Alliance before certification is granted. For more information, please visit https://www.dali-alliance.org
