Using this communication object, a ballast fault can be sent or read.

A ballast fault can occur in one of the following situations:
The ballast malfunctions and does not send telegrams on the DALI control line.
The ballast has no ballast operating voltage and does not send telegrams on the DALI control line.
The DALI control line to the ballast is interrupted, so that the DGN/S does not receive a ballast status response.
The ballast has lost its address, a query from the DGN/S remains unanswered.
Note
In order to guarantee correct evaluation of a ballast fault, the DGN/S has to know how many ballasts are to be
monitored. This is implemented by one-time activation of the communication object Detect ballasts (no. 28). Using
this function, the DGN/S independently determines which ballasts (DALI devices / DALI addresses) are connected
and uses this state as a reference value. Here not only the number but also the address of the DALI device is
registered. If this system has to be modified, the option Detect ballasts should be activated.
The process does not need to be repeated when exchanging a DALI device with the same address. The new DALI
device receives the old DALI address and assumes the position of the DALI device it replaced.
The function Detect ballasts can be triggered not only via the communication object Detect ballasts but also manu-
ally by pressing the button
Software-Tool via button Detect ballasts in the window Options.
