INTRODUCTION

The DALI Controller, Cat No. CD250, allows easy control of fluorescent ballasts supporting the DALI (Digital Addressable
Lighting Interface) specification. The DALI controller provides a cost-effective and easy way to control individual ballasts, a
group of ballasts, or call scenes. There are two types of operations of the CD250, which are Non-Scene and Scene Control.
Within these operations, there are several modes which allow the user great flexibility in how the CD250 is used. The CD250
comes installed with an individual/group controller face and a scene controller face change kit is included.

DESCRIPTION

The DALI Controller has a user-friendly interface. The DALI Controller has two Operations: Non-Scene and Scene operation.
Within the Non-Scene Operation, there are the non-scene individual and non-scene group modes. The non-scene individual
ON/OFF mode offers control of up to 4 separate DALI compatible ballasts. In this mode, the DALI controller can DIM/BRIGHT
up to 4 individual ballasts. On a DALI Network, the user can control up to a maximum of 64 individual ballasts using multiple
DALI controllers (CD250). For example, if one controller controls ballasts 1-4, a second CD250 controller can be added and
programmed to control ballasts 5-8.

When in non-scene group mode, the controller controls up to 4 programmed groups of DALI compatible ballasts. In that group
mode, the DALI controller provides ON/OFF and DIM/BRIGHT control for up to 16 groups of DALI compatible ballasts.

In Scene operation, the user has the option of either being able to control the DALI compatible ballasts under the scene
individual, scene group, or scene broadcast modes. When in scene individual mode, the controller calls programmed “presets”
for a single ballast. When in scene group mode, the controller calls “preset” light levels for a group of ballasts. In scene
broadcast mode, the DALI controller calls presets for ALL ballasts on that DALI network.

The DALI Controller has a removable face to represent the Operation the controller is in. To determine the mode the controller
is in, the user must enter the Programming sequence. The programming sequences for the various modes are described under
the “PROGRAMMING” section.

FACE CONVERSION PROCEDURE

The face of this device can be changed to represent the mode the DALI controller is in. Simply replace the ON/OFF face with
the scene face on the DALI controller, which is included with the controller (please note that wallplate must be removed).

1. Select the face of the mode you desire.

2. The frame has snaps on its sides. Using a small screwdriver, gently remove the frame from the strap (refer to Figure 7).

3. Take the new frame and position it properly to the strap. Orient the frame so that the ON button/Scene 1 (depending on

which face is installed) is the top button. Line up the plastic snaps with the square holes in the strap. Insert the snaps on one
side of the frame into the strap.

4. Firmly press sideways and down to slip the other snaps into place. The frame snaps in with an audible click. Ensure that all
four snaps are secure. Replace Decora

®

wallplate. The face conversion is complete.

TO OPERATE

DALI CONTROLLER OPERATION:

The functioning of the DALI controller is broken up into two major sections representing the two Operations namely, Scene and
Non-scene within which there are: Individual mode, Group Mode, and Broadcast Mode. Refer to Figure 1 for an illustration.

A.

Non-Scene Operation:

1. Individual Mode: In this mode, the four rows of buttons control four individual ballasts, providing ON/OFF control.

Dimming or brightening will only affect one ballast at a time. The DIM/BRIGHT buttons will DIM or BRIGHTEN the last
selected ballast. To BRIGHT/DIM another ballast, you must press the button for that row to “activate” that ballast. If
control of the same ballast is desired with two different controllers, the corresponding button for that ballast from the
second controller needs to be pressed “ON” before Bright/Dim functionality can be used.
Each row corresponds to a specific address, starting from a base address, which is programmed in the program mode.
The address of each row is sequential, starting from the programmed base address. One controller can control only up to
four individual ballasts. If control of more than 4 ballasts is required, multiple controllers are needed, with each controller
programmed to a different base address. Refer to Table 1A and 1B for details.

2. Group Mode: In this mode, the four rows of buttons control four individual groups, providing ON/OFF control for the

entire group of ballasts. The DIM/BRIGHT buttons will DIM or BRIGHTEN the last selected group. Dimming or brightening
will only affect one group at a time. Each row corresponds to a specific group number, starting from a base group

number, which is programmed in the program mode. The group number of each row is sequential, starting from the
programmed base group number. If multiple controllers are used to control more than 4 ballasts, then each controller
must be programmed to a different base group number. Refer to Table 1A and 1B for details.

NOTES:

• The LED next to each button will light when that button is pressed, indicating the last action taken. When mixing
individual controls with group controls and scene controls on the same DALI loop, the ON/OFF LED indicators may not
represent the actual state of the lights.

•When turning on individual ballast or a group, the lights will turn ON to maximum.

B.

Scene Operation:
Scene Mode: In scene mode, each button calls a specific scene. The scene face on the controller shows scenes 1-7, and

Off. The Off scene is displayed on the controller face as a convenience. The default state of all scenes is un-programmed,
including Off. All scenes (including Off) must be programmed.

The LED next to each scene button will light when that button is pressed.

1. Scene Mode – Individual: When the CD250 is in the scene mode, and the individual/group selection is set to individual,
the scene controller will call one of 8 presets for the ballast with the same address

(short address)

as the scene

controller. The individual ballast can be dimmed or brightened using the DIM/BRIGHT buttons.

2. Scene Mode – Group: When the CD250 is in scene mode, and the individual/group selection is set to group, the scene
controller will call a scene [either 1-8 or 9-16 (scenes 8 and 16 need to be programmed Off)], for the group number
programmed. The group can be dimmed or brightened using the DIM/BRIGHT buttons.

3. Scene Mode – Broadcast: When the CD250 is in scene mode, and the individual/group selection is set to group, AND
the Broadcast selection is set, the scene controller will call a
scene for ALL groups. All groups can be dimmed or brightened
using the DIM/BRIGHT buttons.

ADDRESSING AND GROUP IDS:

The DALI ballasts must be assigned addresses. When programming
the CD250 to work as an individual controller, the ballasts are given
addresses that correspond to the address programmed into the
controller. One controller can control up to 4 individual ballasts. To
enable this functionality, the CD250 must be programmed with a base
address. The base address is used by the CD250 to provide 4
sequential addresses, one for each row of buttons. So if the base
address is set to 2, the rows correspond to addresses 2,3,4,5 (from
top to bottom).

Non-Scene Individual Mode:

When using multiple controllers, the base address of each
controller must be programmed. There are 64 individual ballasts
allowed on the DALI loop. To control 64 individual ballasts from the
CD250, we need to install 16 CD250’s (16x4 = 64), and assign a
base address to each controller. This means that the range of
base addresses is from 0 to 63, and one base address
corresponds to 4 DALI addresses. When programming the base
address, a number from 0 to 63 must be chosen. From a base
address, the CD250 maps rows on each controller to a DALI
address. When the programming procedure is finished, each of
the ballasts chosen will have an address that corresponds to a
particular row. Note that it is possible to have the same ballast
controlled by more than one controller depending on what base
address is programmed on the devices (refer to Table 1A).

However, the user may opt to address the controllers such that
four ballasts are controlled uniquely by one CD250 device and
choose not to have overlapping functionality. If this is desired,
refer to Table 1A for a description of how base and DALI
addressing works in this situation. Note that the DALI addresses
will rollover after reaching address 63. The short address will
rollover to 0 if the base address is such that rollover is forced

(refer to Table 1B).

Non-Scene Group Mode

When controlling groups, it is necessary to provide a group Id.
There are 16 groups available. To control 16 groups from the
CD250, we need to install 4 CD250’s, and assign a base group ID
to each controller, just like in the case of individual control. The
address rollover works the same way in Group mode as in
Individual mode described above.

PROGRAMMING

There are two types of programming for the CD250. There is MODE and address programming, called program mode A (PMA)
and DALI setup programming, program mode B (PMB). The programming steps are split into separate operations to simplify
programming. PMA is used for programming the MODE of operation and controller base addresses. This is specific to the
CD250. PMB is used for mapping the various buttons on the CD250 to different ballasts, and requires interaction over the DALI
loop with the ballasts.

To enter the program mode, the program button is used in conjunction with the 8 LEDs located near each of the 8 buttons. The
LEDs indicate which of the options are selected, or indicate a binary number relating to an address. Included in this document
are matrices of the LED patterns to ease the programming operation.

Addresses are programmed using binary notation, which represents numbers as 0’s and 1’s. For the programming of
addresses, the LED status definitions are:

Zero LED blinking
One LED continuously lit
The LED definitions for MODE programming will be explained under the appropriate section.

Mode and Address Programming (PMA):

To enter mode and address programming, press and release the program button once. All of the LEDs will flash to indicate
the controller is now in Program Mode A (PMA). The LEDs corresponding to the address and mode bits set to ONE stay on
all the time in this mode. The buttons next to each LED will toggle the state of the LED. The DIM and BRIGHT buttons have
no meaning in this mode.

To terminate program mode A, press the program button while in program mode A.

DALI Setup Programming (PMB):

Pressing and holding the program button for more than 5 seconds will initialize the DALI setup procedure. This procedure is
necessary to address the ballasts and bind them to the certain buttons on the controller. The setup procedure depends on
the mode that has been selected. When this setup mode is entered initially, the row of LEDs will blink sequentially (the
‘running’ lights) to indicate the DALI setup programming mode. They will then blink each column on and off sequentially.

This will indicate the controller is ready to begin programming.
The setup mode can be ended by the following means:

- Successful ending of setup procedure (if there are no more ballasts to find).

-Termination by user by pressing program button during setup procedure.

- After 15 minutes if no actions have been taken.

RESETTING THE CONTROLLER

If after switching to the setup mode, the user continues to hold the program button for 10 more seconds, the controller will
RESET all devices on the DALI bus to the default values according to the DALI specification. After this the setup and
program modes will be terminated. Resetting the controller does not affect the programming or addressing mode that the
user may be in.

PROGRAMMING FOR NON-SCENE OPERATION

To program a controller, the controller base address and mode of operation need to be programmed using Program Mode A
(PMA), followed by mapping the ballasts to the controller using Program Mode B (PMB).

PMA for Non-Scene Individual Mode:

To enter mode and address programming, press and release the program button once. All of the LEDs will flash to indicate
the controller is now in Program Mode A (PMA). Set LEDs 6 & 7 to flashing (zero) to select non-scene individual control for
the device. See Figure 2 for the meaning of the LEDs in PMA for this mode, for the case when the CD250 is NOT in scene
mode, and used as an individual control (LEDs 6 & 7 flashing). After the base address and mode have been set, press and
release program button once to exit PMA.
LEDs 0-5 indicate the binary form of the base address for individual mode. To program the Base Address of the controller in
Non-Scene Individual Mode, the binary form of the Base Address must be set according to Table 2 below.

PMB for Non-Scene Individual Mode:

Pressing and holding the program button for more than 5 seconds will initialize the DALI setup procedure (PMB). Once the
PMB is entered, all of the ballasts on this DALI loop will turn on to minimum brightness. At the time the blinking pattern
changes from the running lights, to the column blinking, one of the ballasts will turn on to maximum brightness. The CD250
is now ready to program ready to “map buttons to ballasts”.
If the user wants this particular ballast to be controlled by this controller, the user must choose which button to bind to this
ballast by pressing the ON button. To skip any ballast press any OFF button. Note: The user must press a button,
either to bind or to skip. After this, the controller will proceed to search for the next ballast, and the procedure is repeated.
This mode will terminate after controller tries all available ballasts on the bus, or when the user presses the program button
one more time to exit the programming mode.

PMA for Non-Scene Group Mode:

To enter mode and address programming (PMA), press and release the program button once. All of the LEDs will flash to
indicate the controller is now in Program Mode A (PMA). Set LED 6 to flashing (zero) which will place the device in non­scene operation and LED 7 to lit (one) to select non-scene group mode for the device. Refer to Figure 3 for the meaning of
the LEDs in PMA, for the case when the CD250 is NOT in scene mode, and used as a group control (LED 6 flashing, LED 7 lit).
LEDs 0-3 indicate the binary form of the base group address for group mode. See Table 3 for an explanation of the binary
numbers for group ID. With group operation selected, LEDs 4 and 5 have no meaning, and will be OFF (flashing).

NOTE: Assigning individual ballast addresses must be done in PMB Individual Mode.

PMB for Non-Scene Group Mode:

Pressing and holding the program button for more than 5 seconds will initialize the DALI setup procedure (PMB). Once the
PMB is entered, all of the ballasts on this DALI loop will turn on to minimum brightness. At the time the blinking pattern
changes from the running lights, to the column blinking, one of the ballasts will turn on to maximum brightness. The CD250
is now ready to program ready to “map buttons to ballasts”.
The user must decide what groups the selected ballast is to be a part of.

•To include the selected ballast at Maximum to a group, press the corresponding ON button

•To exclude this ballast from the group, press the corresponding OFF button.
The LEDs near each pressed button will stay on after the action (pressing ON or OFF). You have to press all 4 buttons for
the selected ballast (either on or off) to continue to the next ballast. That will determine which groups the current ballast will
be in. After this, the controller will proceed to search for the next ballast, and so on. The mode will terminate after the
controller tries all available ballasts on the bus, or when the user presses the program button one more time to exit the
programming mode.

For Example:

Consider that you have 4 ballasts on the DALI loop (ballasts A, B, C & D), and you want to control ballasts A & B as a group.
Here are the steps.

• Set the base address to 000000, and configure the CD250 for Non-Scene group mode in the PMA.

• Enter the PMB.

•When ballast A turns to max. brightness, press the ON button in the first row (on the CD250). Press the OFF button in

rows 2,3 & 4.

•When ballast B turns to max. brightness, press the ON button in the first row (on the CD250). Press the OFF button in

rows 2, 3, & 4.
NOTE: The ballasts will randomly turn to maximum brightness, and only one will turn to maximum brightness at a time.
When ballasts C & D turn to maximum, press the OFF button in ALL rows.

• This will place ballasts A & B into Group 0 (the first group number of the controller is the same as the set base address
of the device).

• The programming mode has ended. The CD250 is ready for operation.

PROGRAMMING FOR SCENE OPERATION

PMA for Scene Individual Mode:

To enter mode and address programming (PMA), press and release the program button once. All of the LEDs will flash to
indicate the controller is now in Program Mode A (PMA). The mode and address programming are different for scene
operation than for non-scene operation. When in scene operation, the user must select either individual or group mode.
When choosing scene individual mode, the LED meanings are the same as in non-scene individual mode, refer to Figure 2.
The only, yet critical, difference is that in scene individual mode, the binary address programmed with LEDs 0-5 indicates
which ballast to send the preset commands to (

short address

) instead of the controller base address as in non-scene
individual mode. To place the controller in Scene operation, set LED 6 to be lit. Set LED 7 to flashing to enter scene
individual mode. When in scene operation and the individual mode is chosen, the LED meanings are shown in Figure 4.
LEDs 0-3 indicate the scene preset number for the scene to be called for. LED 4 indicates which scene bank is to be used,
Scene Bank A (scenes 1-8), or Scene Bank B (scenes 9-16). Scene Bank A is chosen if the LED is flashing.

PMB for Scene Individual Mode:

Pressing and holding the program button for more than 5 seconds will initialize the DALI setup procedure (PMB). With the
CD250 in scene operation, and the individual mode selected, up to 8 different ballast presets can be programmed for a
single ballast. To program, it is useful to have two controllers connected, one to program the presets, and the other to set the
light levels.
To program the presets, set one controller to individual control, and program the ballast addresses as done in Non-Scene
Operation, Individual Mode. Use this controller to set the preset level for the ballast desired. Put the other controller in
scene: individual mode, enter the PMA, and set the controller address to the same ballast which dimming is desired. Now
enter the PMB on the scene individual controller, and press the button that is desired to call the preset. The scene individual
controller will exit the PMB. Repeat this procedure for all presets desired for the particular ballast.
To program presets for multiple ballasts, the whole procedure must be repeated, using the different ballast addresses
desired. For example, if the user wants to call scenes for ballast 0, the scene: individual controller’s binary address must be
set to 0 in the PMA. If, however, if the user wants to call scenes for ballast 1, the scene individual controller’s binary address
must be set to 1 in the PMA.

PMA for Scene Group Mode:

To enter mode and address programming (PMA), press and release the program button once. All of the LEDs will flash to
indicate the controller is now in Program Mode A (PMA). The mode and address programming are different for scene
operation than for non-scene operation. When in scene operation, the user must select either individual or group mode.
When choosing scene group mode, the LED meanings are the same as in non-scene group mode, refer to Figure 3. To
place the controller in Scene operation, set LED 6 to be lit. Set LED 7 to be lit to enter scene group mode. When in scene
operation and the group mode is chosen, the LED meanings are shown in Figure 5.
LEDs 0-3 indicate the scene group number for the scene to be called for. LED 4 indicates which scene bank is to be used,
Scene Bank A (scenes 1-8), or Scene Bank B (scenes 9-16). Scene Bank A is chosen if the LED is flashing.

PMB for Scene Group Mode:

Pressing and holding the program button for more than 5 seconds will initialize the DALI setup procedure (PMB). With the
CD250 in scene operation, and the group mode selected, scenes can be programmed. In this mode, scenes will be called
for a particular group. To program, it is useful to have two controllers connected, one to program the individual ballast levels,
and the other to set the light levels.
It is important to note that the user must set the light levels for all of the ballasts in a group before the scene can be
programmed. It will be useful to create a table that lists the address of all ballasts installed, and to which groups they belong.
When programming more than four ballasts, it is important to program all of the ballasts in the group with an address. This
will allow easy setting of the light level for scene programming. This is most important when there are more than 4 ballasts in
a group, because only four ballasts can be controlled at a time from a CD250. For example, in order to set the levels for 8
ballasts, first the levels must be set for the first four, the base address on the CD250 changed, and then the light levels set
for the second four. And so on for more than 8 ballasts. Again, it is very useful to have the ballast addresses set ahead of
time.
To program scenes for ballast groups, set one controller to non-scene group mode and create ballast groups. Use this
controller to set the light level for each group of ballasts. (

It may be necessary to change the address of this controller in

order to set the light levels for all ballasts in a group

). Put the other controller in scene group mode, and set the controller
group number to the group desired. Now enter the PMB on the scene: group controller, and press the scene button to be
programmed. The scene: group controller will exit the PMB. Repeat this procedure for all scenes desired for the particular
group of ballasts.

PMA for Scene Broadcast Mode:

To enter mode and address programming (PMA), press and release the program button once. All of the LEDs will flash to
indicate the controller is now in Program Mode A (PMA). To place the controller in Scene operation, set LED 6 to be lit. Set
LED 7 to be lit to enter scene group mode. Set LED 5 to be lit to select broadcast mode. Note that broadcast mode will work
ONLY when the controller is in scene group mode (LEDs 6 & 7 lit). When the scene broadcast mode is chosen, the LED
meanings are shown in Figure 6.
LEDs 0-3 indicate the scene group number for the scene to be called for. LED 4 indicates which scene bank is to be used,
Scene Bank A (scenes 1-8), or Scene Bank B (scenes 9-16). Scene Bank A is chosen if the LED is flashing. LED 5 indicates
broadcast mode. If the LED is lit, then the CD250 is in scene broadcast mode, and the base group ID is ignored. All scenes
will be called for on ALL devices on the DALI network.

PMB for Scene Broadcast Mode:

Pressing and holding the program button for more than 5 seconds will initialize the DALI setup procedure (PMB). When the
CD250 is in scene broadcast mode, the scene controller will call a pre-programmed scene for ALL groups. All groups can be
dimmed or brightened using the dim/bright buttons.

TROUBLESHOOTING

• If NO LED’s are lit; there is no power

- Check wiring.

• If LED does NOT light when the button is pressed

- Check power wiring connections.

For Multiple DALI controllers on the DALI Network:

• The DALI controller has power (the LED’s light up when pressed) but pressing the buttons have no effect on the lights; there
is no communication between the DALI controller and the DALI compatible ballast or the DALI network.

- If the LED does NOT flash when a button is pressed, see above.

- If the LED does light up and all wiring is correct, check the base address of the DALI controller and the mode of the DALI
controller.
