EIB / KNX bus voltage failure
If the DALI-Gateway is supplied with AC or DC operating voltage,
communication with the connected DALI devices is possible after an
EIB / KNX bus voltage failure. The manual test function of the DALI outputs
(channels) is possible.
The behaviour of the DALI devices can also be defined in the parameters.
The parameter "Reaction on DALI or EIB bus voltage failure" is available for
this purpose in the General parameter window. The following options are
available for the DALI outputs: no change, turn on value, maximum and
minimum dimming value or Off.
Any scene sequences that have been started and the dynamic operating
mode (e.g. staircase lighting function) continue to run if "no change" has
been selected in the General parameter window in the event of bus voltage
failure. The DALI faults, ballast and lamp faults are also detected without
EIB / KNX bus voltage. The corresponding fault telegram cannot be sent if
the EIB / KNX bus voltage is not present. This means that a DALI fault in the
EIB / KNX environment is not detected during an EIB / KNX bus voltage
failure and the fault information is lost. If a faulty lamp is replaced during an
EIB / KNX bus voltage failure, the telegram "Fault Lamp" with the value "0"
(no fault) can likewise not be sent and is lost.
After an EIB / KNX bus voltage failure. the information concerning the
device selected with the object "Select Device" is lost.
The functions "Burn in Lamps" and "Slave mode" remain active and are only
deactivated after recovery of the EIB / KNX bus voltage.
DALI voltage failure
A failure in the DALI voltage (e.g. short circuit) of a channel is indicated by
the yellow DALI fault LED which lights up if the operating voltage is applied.
Communication with the connected DALI devices of the channel is not
possible without DALI voltage.
The behaviour of the DALI-Gateway and the connected DALI devices must
be parameterised on failure of the DALI voltage.
The parameter "Reaction on DALI or EIB bus voltage failure" is available in
the General parameter window. The following options are available for the
DALI outputs: no change, turn on value, maximum and minimum dimming
value or Off.
The communication object "Channel X - Telegr. Fault DALI" can be activated
in the Status parameter window. Depending on the parameterisation, the
disruption in the DALI voltage of the channel is automatically routed via this
object or via a read request.
If required, an acknowledgement of the fault signal can be parameterised.
The general communication object "Fault Acknowledgement" is available
which enables both the reset of the 230 VAC fault signal and the ballast,
lamp and DALI fault signals of the individual channels.
The burn-in time function remains active and is continued after voltage
recovery for the remaining period. The slave mode also remains activated.
