Domino
DFDALI
It is suggested to use, for the DALI line, a normal 2-core
cable with double insulation. It's allowed to lay these cables
in the same pipe in which there are power cables, provided
that they have double isolation too.
It is recommended to avoid the using of multi core cables
carrying both the two DALI signals and ballast supply, be-
cause the capacitive coupling between the signal wires and
the power lines may cause very dangerous conditions for
the human safety.
The following table gives some rules for the MINIMUM
cable section. As said above, no special cables are re-
quired for the DALI line, provided that they have double in-
sulation. In any case, the distance between DFDALI mod-
ule and the farthest ballast must not be more than 300m.
Connection Suggested cable
Domino bus 2 x 0.8 mmq unshielded
DALI SUPPLY
1 mmq (if the power supply is near
to the module)
DALI line
Up to120m: 2 x 0.50mmq
Up to 175m: 2 x 0.75mmq
Up to 230m: 2 x 1.00mmq
Up to 300m: 2 x 1.50mmq
Information on the bus
DFDALI takes, inside the
Domino
bus, 1 output address
and, if enabled, 1 input address. The meaning of the data
field of the two sections will be described in the following.
Input section
On the input address, if enabled, 16 bits are available for
the diagnostics of DALI system, as described in the follow-
ing table:
Point Description

11 Polling disabled
12 Power supply loss on DALI side
13 Test button pressed
14 Lamp failure
15 DALI line broken
16 DALI line short circuit
The first available information (points 1
÷
8 of the channel)
can be chosen by the option “Regulation Status” in the con-
figuration panel featured by DCP IDE or BDTools; the two
possibilities are:
Case 1(unchecked option):
the brightness level of the ballast having address 1 which is
assumed as reference for all the other ballasts. Thus, to
use this function, the ballasts have to be addressed starting
from address 1.
