ezDALI 4-Button / 2-Button Group Controller

Installation and Operation

The DLC4-x or DLC2-x Group Controller is one

component in an ezDALI System. It provides a

simple tool for grouping the DALI ballasts in a

room or zone and manually turning on, off or

dimming each group to create a preferred lighting

level. Automatic OFF, in compliance with energy

codes, can be achieved through an occupancy

sensor input to the system.

The DLC4-x (shown right) controls 4 ballast groups,

and the DLC2-x (inset) 2 groups. The x sufﬁx in the

catalog number refers to button and switchplate color:

2 = ivory, 4 = almond, 7 = white and 9 = grey.

A complete ezDALI system includes the following:

1. Group Controller (DLC) or Group & Scene

Controller (DLCSS)

2. Power Supply (DPS series)

3. Lighting fixtures equipped with DALI ballasts

Optional components in the system are:

4. Remote Scene Switch (DSS4) for use with

Group & Scene Controller (DLCSS)

5. Relay Module (DRM) to control non-DALI fixtures

6. Occupancy Sensor(s)

Features

• Dimming plus ON/OFF control of up to four (or two)

lighting groups

• Logarithmic dimming curves: 1% dimming for linear

fluorescents, 3% for compacts

• Easily create and modify lighting environments

without rewiring and without the use of a PC or

special tools

• Master OFF/Restore allows simple day-to-day control

• Occupancy sensor for automatic OFF

• No complex commissioning

• 2-conductor, Class 2 communications, FCC

approved for commercial/industrial applications

• Impact-resistant Lexan

construction with screwless

wallplate and removable button covers for labeling

Operation

The Group Controller is the source of all commands

to the ballasts. Each of the DALI ballasts in the room

is assigned to one of the four (two) Group buttons. The

light level in that group can then be raised or lowered

by pressing and holding the Group button. This allows

the user to created a preferred lighting level for each

lighting group. Once levels are set for all groups, the

Master button is used to toggle between that lighting

environment and off for normal daily operation. Changing

the lighting environment is a simple matter of readjusting

group levels to the new preferrences.

The Group Controller also provides enhanced occupancy

sensor operation. When the Group Controller receives

a message that the room is occupied, the lighting will

turn on to the user-defined level. When the room

becomes unoccupied, the Group Controller lowers the

lighting for five minutes, and then turns it off. If the

occupancy sensor detects motion during this 5-minute

warning, the Group Controller returns the lights to the

preferred level.

Before starting, read the instructions on the next

three pages. If you have any questions, call our

Service Team at: 888-852-2778.

WARNING

Use only rapid-start sockets. Instant-start

sockets shall not be used. Instant-start sockets

short out the pins of the lamps, so the ballast

cannot provide supplemental heat to the

filaments.

For the purpose of these instructions, we

are using the office lighting plan shown

in Figure 2. There are two linear fluores-

cent fixtures and three wall wash fixtures

Install Wall Box and Run

Class 2 Wiring

Install a two-gang wall box at the desired

location. Run Class 2 wiring between the

wall box and the DPS Power Supply as

shown in Figure 1. We recommend

plenum-rated 2-conductor stranded wire

with jacket, #18 AWG minimum.

Create Preferred

Lighting Levels

Adjust the lighting levels of each group

by pressing and holding the Group

button to ramp the lighting up or down.

Releasing the button stops the ramping.

Pressing and holding again reverses the

direction. A group may be turned on or

off by pressing and immediately releas-

ing the Group button. Each Group LED

will indicate the ON/OFF status of that

group. The Master button will toggle

between the preferred levels and off.

Labeling the Buttons

The individual Group buttons provide

space for

⁄8

x 1

⁄16

directory labels. The

labels can be attached by removing the

clear lens, positioning the label and

replacing the lens as shown below.

If desired, the buttons may be completely

removed from the base and labeled

separately. This method allows better

alignment of the labels. To remove a

button from the base, simply pry it off the

retainer. Replace the button by snapping

it back into the retainer.

Troubleshooting

None of the fixtures respond to the

Controller.

• If the fixtures do not turn on when

power is first applied, check the lamps.

Then check for power to the fixtures.

• Confirm that ballast wiring to lamp

sockets conforms to the wiring diagram

on the ballast. Check that the lamp

socket pins are not shorted (Remove

the lamps and disconnect the socket

wires. Measure the resistance across

the contacts.)

• If the fixtures turn on when power is

cycled, but do not respond to the

Controller, first check for power to the

Controller by observing the Locator

light on the bottom bezel. If it is lit, the

Controller is receiving power.

• Check the voltage output of the Power

Supply. First, disconnect the data bus

at the Power Supply and measure the

DC voltage of the Power Supply output

to the data bus. It should be 14-16

VDC. Repeat with the bus plugged in.

The voltage should not change. If it

does, isolate the open or short.

• If not, check that the Power Supply

LED is on steady (GREEN indicates

the occupancy sensor is in occupied

mode; RED, unoccupied). If not, check

power to the Power Supply.

• If the Power Supply LED is flashing

RED, the connection between the

Controller and Power Supply is shorted.

Turn off power and isolate the short.

• If the LED is flashing GREEN, the DALI

bus to the fixtures is shorted. Turn off

power and isolate the short.

One fixture is not responding.

• Check for an open circuit between the

ballast and the DALI bus.

• Check that the ballast has been

programmed into the desired group:

- Remove the wall plate and open the

Master button.

- Press SELECT. Ballast #0 will turn

on at 100% and the LED for the

group to which it was assigned will

begin flashing.

- Continue to press SELECT until you

reach the fixture that is not responding.

- Press the appropriate Group button

to add it to that group.

- Press STORE to enter the new

assignment.

- Press the Group button to confirm

correct operation.
