DLCSS4-x
ezDALI Group & Scene Controller
Installation and Operation
The DLCSS4-x Group & Scene 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 scene
or preset. It also provides the means to memorize
the preferred lighting scenes. Automatic OFF, in
compliance with energy codes, can be achieved
through an occupancy sensor input to the system.
The DLCSS4-x controls up to 4 ballast groups and 4
lighting scenes. 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 lighting
groups
• Logarithmic dimming curves: 1% dimming for linear
fluorescents, 3% for compacts
• Easily create and modify lighting scenes without
rewiring and without the use of a PC or special tools
• Occupancy sensor for automatic OFF
• No complex commissioning
• 2-conductor, Class 2 communications, FCC
approved for commercial/industrial applications
• Impact-resistant Lexan

Operation
The Group & Scene 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 Group
buttons. That group can then be raised or lowered by
pressing and holding the Group button. This allows the
user to created a preferred operating scene for each
lighting group. For the Controller to memorize the
scene, the user simply presses and holds one of the
four Scene buttons, similar to memorizing a station on
a car radio. The Master button will toggle between the
last scene and OFF for normal daily operation.
The Group & Scene Controller also provides enhanced
occupancy sensor operation. When the Controller
receives a message that the room is occupied, the
lighting will turn on to the last scene selected by the
user. When the room becomes unoccupied, the
Controller lowers the lighting for 5 minutes, and then
turns it off. If the occupancy sensor detects motion
during this 5-minute warning, the Controller returns
the lights to the last scene activated by the user.
Before starting, read the instructions on the next
four 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.

Controller addresses the ballasts as
follows:
1. First, the Controller sends an OFF
message to all ballasts.
2. Then, one by one, each ballast will
turn its associated lights on, as the
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 four linear fluores-
cent fixtures and seven wall wash fixtures
Install Wall Box and Run
Class 2 Wiring
Install a two-gang wall box at the desired

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.
Create Scenes
1 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 immedi-
ately releasing the Group button. Each
Group LED will indicate the ON/OFF
status of that group.
2 When the desired light level for each
group has been reached, press and
hold the Scene button. The Scene
LED will turn on indicating the scene
has been memorized. Scene 1 in the
example shown in Figure 4 is set for
audio/visual presentations.
3 Repeat for additional scenes.
Labeling the Buttons
The individual Group and Scene buttons
provide space for

labels. The labels can be attached by
removing the clear lens, positioning the
label and replacing the lens as shown
below on a DLC4-x Group Controller.
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.
