Domino
DFDALI
DFDALI: DALI gateway
DFDALI module allows to manage up to 32 DALI ballasts
(or similar devices) through the
Domino
bus.
DFDALI module can be successfully employed in domestic
and professional lighting applications, where systems com-
municating by the DALI protocol are used.
DFDALI module offers the following main features:
✗
all timing functions are accomplished by the module
and it may be controlled by any real or virtual input of
the system, by supervisor or by video terminal
✗
it can operate without DFCP controller
✗
possibility of control from one or more pushbuttons con-
nected to
Domino
bus
✗
Up/Down and Single commands may be defined for the
manual regulation of lighting level
✗
automatic brightness regulation (also without DFCP)
✗
programmable ramp, in the range 0 to 60 seconds
✗
setting of minimum and maximum output levels
✗
dynamic lights scenes can be easily implemented
through DFCP
✗
the current brightness level may be stored and then re-
called; up to 16 presets are available to create “real
time” lighting scenes; the preset will be stored in the
non-volatile memory of the ballasts
✗
if a
Domino
or DALI bus failure occurs, the output level
will be automatically set to a user-defined level
✗
diagnostics of short circuit on the DALI line and lamp
failure
✗
galvanic insulation between DALI and
Domino
buses
The 32 devices for each line can be controlled as follows:
Broadcast:
each command sent on the DALI line will be ex-
ecuted by all the connected devices, therefore all the re-
lated devices will behave in the same way.
Individually:
the commands will be individually sent to each
device, therefore each single device will behave independ-
ently; for this operation, the DALI devices must be ad-
dressed as described in the following paragraphs.
Groups:
the command will be sent to groups, therefore
each group of devices will behave independently; for this
operation, DALI devices must be addressed and the groups
must be defined as described in the following paragraphs.
DFDALI module can operate in systems with or without
DFCP controller. In all cases, the module can perform Up,
Down and Single Command functions by real or virtual in-
puts (see in the following of this manual); moreover, saving
and recalling of sceneries can be accomplished by the
module.
The power supply needed for DFDALI module operation is
derived from the
Domino
bus itself and from an auxiliary
power supply for the DALI section.
Three fixed 2-way terminal block allow the connection of
the module to the Domino bus, to the auxiliary power sup-
ply and to the DALI bus.
Near to the
Domino
bus terminal block, the module fea-
tures a small pushbutton for the assignment of the address
and a green LED that shows the operating status; this
green LED normally flashes every 2 seconds about to sig-
nal that the module is properly supplied and operating.
Near to the DALI bus terminal block, the module features a
small pushbutton for the manual command of the connec-
ted devices; the function performed by this button are the
continuous regulation of the brightness level and the one-
touch switching on and off. Near to this button, a yellow
LED reports the communication activity on the DALI line or
the diagnostic.
Removing the cover of the bus terminal block, a small con-
nector (PRG) can be accessed; this one allows the connec-
tion to DFPRO optional tester/programmer.
DFDALI module is housed in a standard DIN 4M box for rail
mounting.
Note: this technical sheet applies to DFDALI modules
equipped with firmware 2.2 or higher.
Address programming
DFDALI module takes one output address and, if enabled,
one input address. A white label on the front panel allows
the writing of the assigned address for an immediate visual
identification. For details about address programming refer
to the related documentation.
Wiring diagram
The schematic diagram in Figure 1 shows the connections
to be made between DFDALI module and the
Domino
bus,
the auxiliary power supply and the DALI line, using cables
as described in the table in the following of this same para-
graph. As said above, DFDALI module performs galvanic
insulation between DALI section and
Domino
bus by
means of photo couplers inside the module.
The auxiliary power supply (AUX SUPPLY in the schemat-
ic) can be a transformer with 12V~ secondary winding (at
full load) 3VA, or it can be a stabilized dc power supply 12V
±
5% / 0.25A; in this last case the polarity is automatic,
so the positive pole can be connected indifferently to the
terminal 19 or 20.
