DLC4-x / DLC2-x
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

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.

turn its associated lights on, as the
Group Controller assigns its short
address (0-63). When complete, all of
the ballasts in the room will be ON at
their maximum level.
Create Groups
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

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.
