Design Build Guidelines
• Specifications- Provide outline of minimum quality and expectations
• Historical Requirements- Dictate a portion of the scope or design (ie. Cannot penetrate or deface existing surfaces)
• Building Management Requirements- In this case we had specific fixture requirements, as well as set back restrictions, lamp colors, BMS and lighting control interface
(cont’d) Design Build Guidelines
• Lighting Restrictions- Lighting (fluorescent vs. incandescent), especially in California can get tricky with Energy Conservation Act Title 24. Lighting budget also plays into lighting design
• Lighting Control- Title 24 has minimum guidelines. Design criteria and use of space are also implemented
(cont’d) Design Build Guidelines
• All Applicable Codes- This dictates wiring methods, egress, fire-life safety,etc.
• Budget- Small budget, Fewer options
Process of Selecting Lighting Package
• Package: PackagePackage is the keyword. Key resource is the Light Representatives
• Design Criteria:Understanding Spec & Scope• Budget: Critical element is to match dollars
with space requirements• Communication: Sales & marketing insure
client understanding final package
Base Bid Lighting Controls Criteria
• Use of Space– Conference Rooms– Small Offices– Large Open Areas
• Title 24 (must be implemented)
• Building Management Interface
• Owner Design Criteria
Control Methods: Standard Lighting Control
• Individual switching of office and open areas– LV Lighting Control Panel and Local Devices
• Multi-Level Switching– Two Gang Devices/Two Ballast Fixtures
• Dimming of a single room or fixture– Fluorescent Dimmers & Dimming Ballast
(continued)
Control Methods: Standard Lighting Control
• Dimming to a pre-set scene sequence– Full Grafik Eye System
• Occupancy Sensors
Control Methods: DALI Lighting Control
• Individual switching of office and open areas– via DALI
• Multi-Level Switching – via DALI
• Dimming of a single room or fixture – via DALI
• Dimming to a pre-set scene sequence – via DALI
• Occupancy Sensors – non DALI
Bringing the System Together
• Fixture Package• Fixture Control• DALI Protocol• DALI Ballast - Coordinate with fixture manufacture• Electrician - Willing electrician; Education of the
simple install• DALI Magic - DALI compatible switching, interface
solutions (non DALI fixtures), and startup & commissioning)
PRO-Electrical Quotes
• More forgiving (all switching options are always available, whereas conventional switching requires multiple switch legs)
• Smaller pipe and fewer wires to pull
• Layout is simple
• Changes or added switches are easy
• Quicker lighting control installation
(cont’d) PRO Electrical Quotes
• Change order friendly (owner & contractor)
• Non-electrical programming (software based)
• Ballast self-addressing (no dip switches)
• Troubleshoot wiring easier (fewer wires and make-up)
CON-Electrical Quotes
• Interface wiring between ballast and fixture manufacturer was poor/bad wiring (a few mis-wired ballasts)
• Electricians worried about mixed voltages and make-up in common boxes
• DALI on a non-conduit installation (ie. MC) no value savings in labor
• Call backs could be confusing to service people
Summary
• When questioned, all of the electricians involved would do another DALI system. All were impressedimpressed and thought it was a good educationeducation.

Ballast
DALI Message DescriptionGo to light level Sets light level from 1% tp 100%Go to Minimum Sets light level to minimum light level for this settingTurn Lamp On/Off Turns to lamp(s) On/Off (power remains on the ballast)Go to level Sets light level at predifined levelWhat is your current light level? Respsonse in percentageWhat is the ballast status? Response is a variety of messages
• Supports two way communications• Stores group / scene programs• Monitors lamp performance, provides
energy consumption data. • Provides predictable dimming
response• Issue – CFL ballast were not available
until after the space was occupied, which created the need for a UL DALI relay module.

DALI Loop Controller (Bus Master)
• Required for any DALI System• Provides power for the DALI dataline
– Actual power supplied was 150 ma, not 250 ma as specified.
– Ballast quantity or power consumption dictates bus quantities.
• Provides protocol translation from DALI - RS-232 • One required for every 64 DALI ballasts
Scene / Group SwitchesSingle gang four button switches• Individual office control.
– Ballast and non dimmed CFL control
• Open Office Control– Arrive / Depart Group Control
• Includes group raise / lower function.

• Used to convert eight RS-232 DALI bus controllers to single Ethernet I./P address.
• Expensive and provides little value.
Software for Commissioning• Assigned unique address
for each ballast– Address routine brings one
ballast to 100%, dims all other ballasts on network.
• Supports replacement or addition of ballasts
• Allows manual control of ballasts
• Configures scenes and groups.
Software for Operation• PC based
– Manages single DALI bus control
– Allows monitoring and control
Server Features• Manages multiple DALI
bus controls• Provides
– Scheduling– Multi bus communication.– Allows employee workstations
to interface to DALI network.
• Stores historical data
Lessons Learned
• Significant IT requirements for this project.
• One manufacturer doesn’t have everything yet.
• Scheduling needs additional development.– Distributed Processing
The Commissioner
By: Charles Knuffke
The Goal of Commissioning
• Verify all components are installed properly and working as specified.
• To ensure that the owner has complete documentation on the system as it was installed.
Why DALI Commissioning is extra important
• More points of control than ever before
• More wire in the ceiling than most systems
• More capabilities means more settings to deal with
DALI Requirements
• All components must be completely installed– Line Voltage Wiring, DALI Communication Bus, All Ballasts
and Fixtures, and any DALI Override devices– No Faking It!
• If power is shut off to DALI bus, all lamps go to 100% by default.
Start by reviewing the Hardware
5 Bus Masters and a Router in a Custom Enclosure
And the switches
Four 4-Button Master Switches by the Main Entry
Four Interface and two 4-Button Switches in the Large Conf. Room
Once everything is ready
• Each ballast address assigned by software wizard, so they are not readily apparent.– Commissioning the 1st Bus took 15 minutes, next bus didn’t
get finished before the end of the first day.
• Start with a Clean Reflected Ceiling diagram and a sharp red pencil.

Identifying the Addresses
• Once each ballast was assigned, 2 people work together to select the address in software, and match it with a fixture in the space.– “Optical Feedback” made the process easy. However,
tenants needed to be advised that we would be testing the system.
– Software has since added a strobe feature.– Several times we had a bus that had to be re-addressed.
This turned out to be due to a bug in the software.

DALI Software
• 4 Separate Tools – Palm Handheld, DALI Tool, WinDim, WinDim-net– Looking forward to Software improvements.
• Originally info entered into ballasts via WinDim was going to have to be re-entered into WinDim-net software (approximately 2400 setpoints).
• Some places, groups were numbered 0-15, others 1-16.
Setting Up the System
• Ballast were assigned to groups, and levels (from 0-255) were set for the various scenes. Groups were exclusive, and easy to track.
• Commands from WinDim could be used to communicate to devices in 3 address manners– Broadcast = All Devices– Group = Specific Group from 1-16– Address = Specific Ballast

Troubleshooting• Had Electrician look for ~16VDC on the DALI bus
to the ballasts, and verify ballast wiring.
• Used the software to detect failures, and sent override commands from the software
• Dataline switch, in addition to overriding groups, had two testing features that helped
• Broadcast On/Off
• Raise Lower entire Group
Project Takeaways
• Knowing the Bus wire runs is Key.– Working with the electrician who did the bus wiring is even
better.
• Keep the busses manageable, and try to control obvious groups together.
• Get full info on all equipment to be interfaced– Conference room has projector lift, screen and shade
controllers. However, lift used a 24V signal, and switch contacts was 120V output.
Project Takeaways
Advice for Future Commissioners
• Learn to use Microsoft Excel• Make sure you’ve got time to check out system,
and understand how checkout will impact occupants.– Each time we connected to a specific bus, we had to re-
initialize, and that caused all lights to drop to low level.– Startup up of this site required approximately 60 hours over
12 visits. This broke down to be about 1/3 “New Technology issues”, 1/3 problem issues, and 1/3 revising setpoints to meet owner desires.
DALI still in Early Adopter Stage
• High tech, but based on Ballast communication within a single DALI Bus– Difficult to take a contact closure across different busses.– No memory of previous levels.– Central Server PC issues commands for standard
scheduling.
Hope for Advances
• Open protocol with information stored in the ballast.– Offers an opportunity for other companies to develop
software, and drives existing package to improve.
• Existing Bus Master is RS-232 In –> DALI Out.– Future Bus Masters could have other inputs, and logic to
assist initial troubleshooting.
