Feedback for the mains voltage supply on the DALI Gateway
The DALI Gateway is able to monitor its supply voltage at the connection. In case of failure the
Gateway is able to send a message telegram to the KNX/EIB before shutting down. Optionally, it is
possible to have the mains voltage supply confirmed.
If the mains voltage supply of the Gateway and the connected DALI devices are connected to the same
phase connector, it is possible to monitor the operating status of the entire DALI system by analyzing
the feedback of the mains voltage.
The DALI Gateway uses the independent “DALI voltage failure” 1-bit communication object 211 for
giving feedback to a voltage drop or return of voltage. The polarity of the telegram is preset: (mains
voltage available = 0, mains voltage failure = 1).
Setting the feedback for the mains voltage supply
The ETS parameterization allows to define whether only a mains voltage supply failure of the DALI
Gateway or whether a mains voltage return is also to be reported to the KNX/EIB. The telegram is
always actively transmitted. As soon as the status of the mains voltage has changed, a one-time
feedback telegram will be transmitted.
Set the "DALI Gateway mains voltage failure / return feedback ?" parameter on the "General"
parameter page to "Yes (only in case of a voltage failure)”.
As soon as a mains voltage failure has been detected at the DALI Gateway, the Gateway will
immediately transmit a feedback telegram. Then it will shut down.
Set the "DALI Gateway mains voltage failure / return feedback ?" parameter on the "General"
parameter page to "Yes (only in case of voltage failure and return)”.
As soon as a mains voltage failure has been detected at the DALI Gateway, the Gateway will
immediately transmit a feedback telegram. Then it will shut down. The DALI Gateway initializes when
switching on the mains voltage supply. It will then transmit a feedback telegram and indicate that the
mains voltage is on.
Set the "DALI Gateway mains voltage failure / return feedback ?" parameter on the "General"
parameter page to "No".
The feedback mains voltage supply status will be deactivated. The communication object is now
hidden.
Feedback on a mains voltage failure can only be transmitted if the bus voltage has been connected
and switched on at the time of the failure.
In case no bus voltage has been connected or switched on at the time of the voltage return, there will
be also no feedback on the mains voltage return. The feedback will not be stored. Thus, no feedback
will be transmitted even at a later time when switching on the bus voltage.
The “DALI voltage failure” feedback is not automatically transmitted to the bus after the return of bus
voltage or after ETS programming with bus voltage applied at the DALI Gateway.
