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

20
(contd) 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

21
(contd) Design Build Guidelines

• All Applicable Codes- This dictates wiring
  methods, egress, fire-life safety,etc.
• Budget- Small budget, Fewer options

22
Process of Selecting Lighting Package

• Package Package is the keyword. Key resource is
  the Light Representatives
• Design CriteriaUnderstanding Spec Scope
• Budget Critical element is to match dollars with
  space requirements
• Communication Sales marketing insure client
  understanding final package

23
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

24
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)

25
Control Methods Standard Lighting Control

• Dimming to a pre-set scene sequence
• Full Grafik Eye System
• Occupancy Sensors

26
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

27
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)

28
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

29
(contd) 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)

30
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

31
Summary

• When questioned, all of the electricians involved
  would do another DALI system. All were impressed
  and thought it was a good education.

36
DALI System Components

• Starfield
• Scene Controls
• In Conference rooms to match A/V controls
• Switch / relays
• Shade Controls
• Projector Lift
• Screen up/down

• Key Issue was that devices could coexist with
  other manufacturers devices without causing the
  system to crash or other devices not to work
  (play nice requirement)

37
Ballast

• 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.

38
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

39
Scene / Group Switches

• Single 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.

DALI Bus
42
Router

• Used to convert eight RS-232 DALI bus controllers
  to single Ethernet I./P address.
• Expensive and provides little value.

43
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.

44
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

45
Lessons Learned

• Significant IT requirements for this project.
• One manufacturer doesnt have everything yet.
• Scheduling needs additional development.
• Distributed Processing

46
The Commissioner
By Charles Knuffke
47
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.

48
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

49
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.

50
Start by reviewing the Hardware
5 Bus Masters and a Router in a Custom Enclosure
51
And the switches
Four 4-Button Master Switches by the Main Entry
Four Interface and two 4-Button Switches in the
Large Conf. Room
52
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 didnt 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.

57
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

58
Excel to the rescue

and again!
61
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

62
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.

63
Project Takeaways
64
Advice for Future Commissioners

• Learn to use Microsoft Excel
• Make sure youve 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.

65
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.

66
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 gt DALI Out.
• Future Bus Masters could have other inputs, and
  logic to assist initial troubleshooting.
