DALI voltage recovery
On DALI voltage recovery, the yellow DALI fault LED is extinguished.
The behaviour of the DALI-Gateway and the connected DALI devices on
recovery of the DALI voltage can be parameterised.
The parameter "Reaction on DALI or EIB bus voltage recovery" 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 defined
in the Status parameter window. Depending on the parameterisation, the
recovery of the DALI voltage of the channel is automatically routed via this
object or 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 fault message communication object. This can be very
helpful when detecting sporadic errors or events which take place during
unmanned monitoring periods.
The functions "Burn in Lamps" and "Slave mode" are continued after voltage
recovery for the remaining period.
