Functional description
No. Function
6 Telegr. Fault Device
&

Channel X Telegr. Fault Device [EIS 1; 1-bit switching]: With this object and depending on
the parameter setting (Status parameter window), a fault message which originates from one
or more ballasts of the channel, is sent or read out (e.g. for maintenance purposes).
Telegram value "1": Fault of one or more ballasts on the channel
"0": No fault
In order to guarantee correct operation, the gateway has to know how many
ballasts are to be monitored. This is implemented by activating the object
"Detect Ballasts" (no. 251) just once. Using this function, the DALI-Gateway
independently determines how many ballasts are connected and uses this
number as a reference value. If this system has to be extended or reduced, the
"Detect Ballasts" option should be reactivated. This procedure is necessary if
the number of ballasts per channel has changed, and not with the exchange of
a ballast on the same channel. The same function as for the object "Detect
Ballasts" can be manually triggered if the test button on the DALI device is
pressed for longer than 5 seconds.
