Introduction
The ABB i-bus
®
DALI-Gateway DG/S 8.1 is a DIN rail mounted device with
a width of 6 modules in the pro
M
design for insertion in the distribution
board. The connection to the ABB i-bus
®
is established via a bus connection
terminal at the front of the device. The DALI Gateway requires an AC or DC
auxiliary supply. The assignment of the physical address, as well as the pa-
rameter settings is carried out via the Engineering Tool Software ETS (from
version ETS2 V1.3 onwards) with a VD2 file. For programming the device
with ETS3, the relevant VD3 file must be applied.
The following functions can be controlled via the KNX with the DALI-Gate-
way DG/S 8.1 in conjunction with devices that have a DALI interface:
Brightness values,
can be switched on, switched off or set per channel.
Individual lighting control,
with adjustable dimming speeds and transition
times is possible.
16 lightscenes,
are assembled together with the 8 DALI outputs (channels).
The scene brightness values can be set, stored and retrieved via the ETS
or the communication object. It is possible to recall or store a scene over
1Bit or 1Byte Object.
In
dynamic mode,
a staircase lighting function or a timed brightness
progression can be assigned to each channel. It is possible to set starting
values, hold values and switch OFF values as well as the corresponding
changeover points individually per channel.
In
slave mode,
each channel can be priority controlled via a 1-byte input
signal. In connection with corresponding KNX devices, constant
lighting control or repeated lighting processes can be controlled.
Lamp and ballast faults
are detected and reported. The status of a lighting
system can thus be continually monitored and the appropriate information
can be routed. Since the device can also function in DC mode, there is
no obstacle to emergency power applications.
The DALI Gateway continually issues the current status of its own operability
as well as the connected DALI devices via
status signals.
Two LEDs on the gateway provide direct information about the status
of the device. They report whether the gateway is functioning correctly and
display errors in the DALI outputs (channels).
To enable the DALI Gateway to function correctly, it must be
ensured that the connected DALI equipment is in accordance with
DIN EN 60929 and IEC 62386 respectively and thus conforms
to the DALI standard.
