!
Before removing the device, be sure that inputs, outputs,
and the DC power supply have been disconnected. By
using a screwdriver, slide the locking device down and
remove the device from the prole rail.
DALI bus line and command connections
The connection to the DALI bus network and the local
commands is done via the screw terminal, located on the
front of the device in the upper part.
The length of the connection cables between the local
commands (N.O. Pushbutton, 0-10V, 1-10V, Potentiome-
ter or other) and the product must be less than 10m; the
cables must be dimensioned correctly and they should be
isolated from every wiring or parts at voltage not SELV.
Use double insulated shielded and twisted cables.
The length and type of the connection cables to the DALI
bus must be compliant with the protocol specication and
with the present regulations and they should be isolated
from every wiring or parts at voltage not SELV. Use dou-
ble insulated shielded and twisted cables.
All the devices and the control signal connected to the
DALI bus and to the local command (N.O. Pushbutton,
0-10V, 1-10V, Potentiometer or other) must be SELV (the
devices connected must be SELV or supply a SELV si-
gnal).
Characteristics of the DALI terminal block
• Screw tightening of the conductors
• Command & bus wiring: 1.5 mm2solid – 1.0 mm2stran-
b) Place the support clamping tooth on the top edge of the mounting
rail and rotate device and support towards the guide until it completely
engages
c) Once fastened, connect the bus line, the inputs and the outputs
Installation scheme
Note. When mounting the device in boards and ca-

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 a qualied planner.
For commissioning the device the following activities are
required:
• make the electrical connections as indicated above;
• power up the bus;
• carry out the device addressing, as described in the
next paragraphs.
Local command
Depending on the local control, the device can manage
di󰀨erent functions on the output loads.
Push dimmer
The intensity and the status change (ON/OFF) are con-
trolled by a N.O. pushbutton.
ded – 16 - 17 AWG
• Conductor stripping recommended: 5.0 - 6.0 mm
• Maximum length of the connection between dimmer-
driver and control device < 10 m
• Length of connection cables < 10 m
Connection of power supply and LEDs
For the power supply use SELV power suppliers with li-
mited current, short circuit protection only and the power
must be correctly dimensioned. In case of usage of a po-
wer supplier with ground terminals, all points of the pro-
tective earth (PE = Protection Earth) must be connected
to a valid and certied protection earth.
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 & LEDs wiring: 1.5 mm2solid – 1.0 mm2stran-
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 module must be less than 10 m; the cables
must be correctly dimensioned and they should be isola-
ted from every wiring or parts at not-SELV voltage. It is
preferable to use shielded and twisted cables.
In case it is needed to connect the device and LED mo-
dules with cables longer than 10m, the installer must gua-
rantee the correct functioning of the system. In any case,
do not exceed 30 m of the connection between the device
and the LED modules.

Automatic detection of the local command type
At the rst switch on, the device is set by default to auto-
matic recognition of N.O. push button command.
• Automatic detection of 0-10V, 1-10V and potentiome-
ter command
The automatic recognition of analog signal 0/1-10V or
potentiometer starts as soon as either a 0/1-10V value
between 3V and 7V is sent out, or by setting the potentio-
meter with value included from 30% and 70%.

Push menu
In the LED dimmer menu, the following functions are avai-
lable:
• minimum dimming value setting;
• power-on ramp (fade in) setting;
• power-o󰀨 ramp (fade oou) setting.
Access to menu
When the LED dimmer is turned on, the output is set at
100% and the minimum dimming value at 1%. To access
the device menu, perform a sequence of 15 clicks over a
period of 5 seconds.

A ash of the LED loads indicates that the rst menu has
been accessed: “MENU 1”. The access to each menu is
sequential.
Menu 1: minimum dimming value setting
Each single click allows you to vary between 7 minimum
dimming values. The following minimum levels are availa-
ble: 0.1%, 1%, 5%, 10%, 20%, 30% and 100%.
Once the minimum dimming value has been selected,
then long press to conrm: a double ash conrms the
passage to MENU 2.
The software can be downloaded from www.ekinex.com
website and its use is described in the application manual
of the ekinex EK-BG1-TP DALI Gateway. The software
requires Microsoft Windows (7 and later).

Menu 2: power-on ramp (fade in) setting
Each single click allows to set the fade in. The following
“fade in” times are available: instantaneous, 1 second, 2
seconds, 3 seconds, 6 seconds.
Once the “fade in” time has been selected, then press
and hold to conrm: three ashes conrm the passage
to MENU 3.
Menu 3: power-o󰀨 ramp (fade out) setting
Each single click allows to set the fade out. The following
“fade out” times are available: instantaneous, 1 second, 2
seconds, 3 seconds, 6 seconds.
After selecting the “fade out” time, then long press to con-
rm: three quick ashes conrm the storage of the set-
tings and the exit from the menu.
Once exited the menu, the LED load connected to the
dimmer output turns on at the minimum value set.
Functions
Relationship between DALI bus and local commands:
on power-up, in case the bus connection is not present,
the local command is active. When the bus connection
is detected, the control passes to the bus. In the absen-
ce of the signal, if the local command is an N.O. button,
the control is passed to the local commands the button is
pressed.
Device addressing
• Simplied method (one ballast connected at a time):
each one will get the address progressively from 0 to
63;
• Random Address Allocation: by connecting all the bal-
lasts at the same time, each one will get a random
address.
Subsequently, the address conguration can be changed
by using an application for parameterization, for example
by downloading the ekinex CGEKBG1TP software to your
PC which allows to:
• congure the DALI system and dene its parameters;
• set the DALI luminaires (groups, scenarios, IDs, etc.);
• test the communication on the DALI bus;
• update the device.
