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.

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 confirms 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
configuration 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 flashes.
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 configuration 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 off, 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.
Configuration and commissioning
Configuration and commissioning activities of the device
must be carried out according to the design of the building
automation system done by qualified 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 first 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 / off 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 flashing. 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 firmware, 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.

The setting of the output channels can also be done using
DALI programmers. An example is shown in the next fi
-
gures.
