Recovery of the operating voltage
On recovery of the operating voltage on the DALI-Gateway, the green
operating LED lights up again.
The behaviour of the DALI-Gateway and the connected DALI devices on
recovery of the operating voltage (supply voltage) of the DALI-Gateway
cannot be parameterised directly.
As a recovery of the operating voltage simultaneously leads to a recovery of
the DALI voltage, the behaviour of the DALI devices can be defined in the
parameters. The parameter "Reaction on DALI or EIB bus voltage recovery"
in the General parameter window is available for this purpose. The following
options are available for the DALI outputs: no change, turn on value,
maximum and minimum dimming value or Off.
The communication object "Telegr. Fault 230 VAC" can be activated in the
Status parameter window. Depending on the parameterisation, the fault in
the operating voltage is routed automatically via this object or only via a read
request.
If the fault acknowledgement is activated, the fault signal remains set until
the fault is rectified and the fault signal is reset via the communication object
"Fault Acknowledgement". Only then is a telegram with the value "0" sent via
the corresponding communication object. This can be very helpful when
detecting sporadic errors or events which take place during unmanned
monitoring periods.
The function of the burn-in time is lost on bus voltage failure and is
deactivated after voltage recovery. The previously elapsed time is lost.
The operating (supply) voltage recovery on the DALI device
means that the lamps switch to the set default brightness value.
Maximum brightness is the default setting. This behaviour
cannot be influenced by the gateway.
EIB / KNX bus voltage recovery
The behaviour of the DALI devices on recovery of the EIB / KNX bus voltage
can be defined via the parameters. The parameter "Reaction on DALI or EIB
bus voltage recovery" in the General parameter window is available for this
purpose. The following options are available for the DALI outputs:
•
no change, brightness value when turned on
•
maximum brightness value
•
minimum brightness value
•
off
The information about DALI faults, ballast and lamp faults which have
occurred during the EIB / KNX voltage failure is routed after EIB / KNX bus
voltage recovery.
After an EIB / KNX bus voltage recovery, the information concerning the
device selected with the object "Select Device" is no longer lost. The device
must be reselected.
If it is parameterised that the scene is to be overwritten with a download, it
will be overwritten with the values which have been defined in the ETS after
EIB / KNX bus voltage recovery.
The function of the burn-in time is lost on bus voltage failure and is
deactivated after voltage recovery. The previously elapsed time is lost.
