Both models have internal status LEDs (4a) and a
feedback button (4b) which, in the EK-GD2-DL-2-LV mo-
del, also allows the selection of DALI DT6 / DT8 mode.
The meaning of the status LED for EK-GD2-DL-1-LV and
EK-GD2-DL-2-LV devices is as follows:
• Green steady on: normal operation and DALI line pre-
sent;
• Green ashing: no DALI line;
• Flashing red: generic output error.
The button (4b) for EK-GD2-DL-1-LV activates the
feedback function, while for EK-GD2-DL-2-LV it allows
the selection of DT6 (1 or 2 channels) or DT8 Tunable

Setup and installation
The steps for installing the device are as follows:
• connect the loads to the “LED OUT” output terminals
of the device;
• for the EK-GD2-DL-1-LV model, connect the local com-
mand to the “PUSH” input if you want to use the “stand-
alone” mode;
• connect the DALI bus to the related DA terminal blocks;
• connect the 12/48 Vdc power supply to the terminal
blocks “DC IN” of the device.
All the devices and the control signal connected to the
DALI bus and to the local command (where available)
must be SELV (the devices connected must be SELV or
supply a SELV signal).

signal on the DALI bus and immediately use the fade,
otherwise the switching on and o󰀨 would be immediate.
• Advanced function (blue status LED): using a DALI pro-
grammer such as USB DALI interface Tridonic, Lunato-
ne DALI Cockpit or similar, it is possible to program the
parameters System Fail Level = 100% and Fade Time
= 0, according to the DALI specications.
The connection cables between the power source “low
voltage” and the product must be correctly dimensioned
and they should be isolated from every wiring or parts at
not-SELV voltage. Use double insulated cables.
The power supply must be dimensioned according to
the load connected to the device. If the power supply is
oversized with respect to the maximum absorbed current,
then insert a protection against over-current between the
power supply and the device.
Characteristics of the supply and LEDs terminal block
• Screw tightening of the conductors
• Power and LEDs wiring: 1.5 mm2 solid – 1.0 mm2 stran-
ded – 16 - 17 AWG
• Power and LEDs stripping recommended approx.: 5.0
- 6.0 mm
• Max torque 0.5 Nm
Outputs
The length of the connection cables between the product
and the LED modules must be less than 10 m; the cables
must be dimensioned correctly and must be isolated from
any wiring or parts with non-SELV voltage. Use double
insulated shielded and twisted cables.
If you want to use connection cables between the product
and the LED modules over 10m, the installer must ensure
the proper functioning of the system. In any case, the con-
nection between the product and the LED modules must
not exceed 30 m.
A further long press of the programming button for at least
5 seconds conrms the setting of the selected function.
The device will always work in both modes: the default or
advanced programming only sets the DALI System Fail
Level and Fade Time parameters without the need for a
DALI programmer.
EK-GD2-DL-2-LV programming
The device is equipped with a programming button on the
front, near the DA terminals, to select the DALI DT6 / DT8
conguration of the channels.
While the status LED is on, a long press of the program-
ming button for at least 5 s allows you to enter program-
ming mode and the LED ashes.
At this point:
• by pressing the button once, the LED lights up purple,
to indicate the programming of both outputs as a single
DALI DT6 channel;
• by pressing the button again, the LED lights up blue,
to indicate the programming of the outputs as 2 single
channels DALI DT6;
• pressing the button again will cause the yellow LED to
light up, indicating that the programming of the outputs
is in Tunable White (dynamic white) with 1 DALI DT8
channel;
• with a long press of at least 5 s the conguration is
saved and the menu is exited;
• after 60 s without further pressing the programming key,
the device exits the menu without saving the setting.
Courtesy light function (EK-GD2-DL-1-LV) only)
When the output is o󰀨, a long press of the local control
button for at least 0.7 s turns on the load at minimum
intensity for 2 s, then starts dimming towards maximum
intensity. If the button is released at this stage, the bright-
ness level stops.
Conguration and commissioning
Conguration and commissioning activities of the device
must be carried out according to the design of the building
automation system done by qualied planners.
For commissioning the device the following activities are
required:
• make the electrical connections as indicated above;
• power up the bus;
• for EK-GD2-DL-1-LV device, it is possible to select the
“stand-alone” mode through the local command (con-
nection to the DALI bus is not necessary);
• carry out the device programming, as described below.
EK-GD2-DL-1-LV programming
At the rst start-up, in case of lack of the DALI bus, the
local control is active and the LED placed under the front
programming key is orange. When the presence of the
DALI bus is detected, control passes to it. In the absence
of the DALI bus, control passes to local control by pres-
sing the button.
Button behavior:
• Short press: on / o󰀨 function;
• Long press: reverses the direction of dimming.
The device is equipped with a programming button on the
front, near the DA terminal: by pressing the programming
button for 5 seconds, the status LED starts ashing. Pres-
sing the button again allows you to select the function of
the device:
• Default function (orange status LED): sets the System
Fail Level parameter = 100% and the Fade Time = 0.7
s), to make the device work even in the absence of a
Note. If the dimmer is used together with a bro-
adcast DALI device, depending on the implemen-
tation of the rmware, the broadcast function may
prevail over the local command.
i
Note. The programming of the parameters men-
tioned above must be carried out only during the
programming phase. If the customer has a DALI
programmer / master, he can reprogram them as
he wishes.
i
The setting of the output channels can also be done using
DALI programmers. An example is shown in the next -
gures.

Status LED
The meaning of the status LED under the programming
button is as follows:
• Green steady on: normal operation and DALI line pre-
sent
• Flashing green: no DALI line
• Flashing red: generic error on the output
If the programming button is not pressed within 1 minute,
the status LED goes into standby. A short press of the
programming button turns the LED back on and shows
the status.
Conguration change
Subsequently, it is possible to change the device con-
guration and addressing using an application for para-
meterization, for example by downloading the ekinex
CGEKBG1TP software to the PC which allows you to:
• congure the DALI system and dene its parameters;
• set the DALI devices (groups, scenarios, IDs, etc.);
• test the communication on the DALI bus;
• update the device.
The software can be downloaded from the website www.
ekinex.com and its use is described in the application ma-
nual of the ekinex EK-BG1-TP DALI Gateway. The sof-
tware works with Microsoft Windows (7 and later).
DT6 with single output channel
DT6 with 2 independent output channels
DT8 with single Tunable White output channel
DALI System fail function
For each device it is possible to set the “system failure”
parameter, that is the brightness level at which the LED
load is set, in case of DALI bus outage.
This setting can be done using a DALI programmer such
as USB DALI interface Tridonic, Lunatone DALI Cockpit
or similar.
The range of brightness values is from 0 to 254 (100%).
If the value 255 (MASK) is set, the last brightness value
is restored.
Note. For the CGEKBG1TP conguration software
to work, it may be necessary to install .NET Fra-
mework 4, which can be downloaded freely from the
Microsoft website.
