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 mm

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.

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

solid – 1.0 mm

stran-

signal on the DALI bus and immediately use the fade,

otherwise the switching on and off 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 specifications.

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.

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.

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.

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.

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.

The setting of the output channels can also be done using

DALI programmers. An example is shown in the next fi-

gures.
