DALI

Digital Addressable Lighting Interface DALI is a protocol dedicated purely for

lighting control

DALI allows individual control andmonitoring of lighting systems

DALI provides precise dimming

DALI promises flexibility in design, and

ease of installation


3/60

Learn How To:

Leverage the benefits of the DALI

technology

Specify DALI lighting controls

Design DALI controls for single rooms,

open offices and whole buildings

Solve DALI installation and

commissioning issues

History:

From Europe

Tridonic and others Digital Serial Interface (DSI) ballasts in 1991

Digital Addressable Lighting Interface (DALI) ballast in 1998

Dropped royalties to gain wide spread acceptance of DALI

IEC DALI protocol (IEC Standard 60929, Annex E & G)

advanced to voting process in year 2000.

Adopted by other leading ballast and control manufactures Formally adopted summer of 2002


7/60

History:

In USA

NEMA Controls Council Wiring Devices, Controls, and Ballasts

Liaison with International ElectrotechnicalCommission (IEC)

DALI subcommittee

IESNA Controls Subcommittee Established to develop a control protocol

Reviewed several existing systems

Asked by NEMA to comment on DALI proposal

DALI

DALI is not a product

DALI is a protocol (a set of rules)

(from ballast perspective)

Power connection

Lamp response

Control interface

Command set


11/60

Protocol:

Power Connection

Universal voltage input

115V to 300V,50Hz to 60Hz

High power factor

Low harmonics

Transient protection

Initial application of voltage lamps go

to full output or other preset level


12/60

Protocol:

Lamp Response Precise dimming curve

Logarithmic curve

Range: 0.1% to 100% for incandescent,1% to 100% for linear fluorescent,

3% to 100% for CF

254 steps (2.8% increase per step)

Based on lamp arc power (This is not lamp lumen output)

DALI Programming (Contd)

Group Addressing

Each DALI loop can support up to 16 individual

groups

Each ballast may belong to any or all of the 16

available groups

Scene Setting

Each ballast may have as many as 16 presetlevels (scenes)

Scenes may be applied to ballasts

Scenes may be applied to groups


29/60

Wiring per NEC

Approved for use in Class 1 and Class

2 installations

DALI wiring may be with line-voltagewiring

Could use a 5-wire prefabricated wiring

assemble Installation must comply with Code

compatible ballast.


44/60

STEP 2:Layout DALI network (2 wires) to each fixture independent of

circuit wiring. Each DALI loop can support up to 64 ballast. Loop

wires can be located in same conduit with power wiring


45/60

STEP 3:Design controls into space and determine easiest connection to

DALI bus. Identify placement of bus power supply and optional

network interface.


46/60

STEP 4:Address DALI ballasts. Determine fixture groupings and map

control devices to fixtures. Each ballast can be assigned to

multiple groups (16 max).
