This communication object is enabled if, in the
parameterized with the Yes option.
Using this communication object, a ballast fault can be sent or read. Using this communication object, a ballast fault can be
sent or read.
Telegram value
A ballast fault can occur in one of the following situations:




It is possible to parameterize if the fault is sent on After a change and/or After request.

This communication object is enabled if, in the
parameterized with the Yes option.
Using this communication object, a DALI fault can be sent or read.
There is a DALI fault if the short circuit persists for more than 500 ms.
Telegram value:
It is possible to parameterize if the fault is sent on After a change and/or After request.

Function
Ballast fault
0 = No ballast fault
1 = Ballast fault (at least one connected ballast has a fault)
The ballast is faulty 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 DLR/S does not receive a status response from the
ballast
The ballast has lost its address, a query from the DLR/S remains unanswered
Note
In order to guarantee correct evaluation of a ballast fault, the DLR/S has to know how many ballasts are to
be monitored. This is implemented by one-time activation of the communication object Detect devices (no.
25). Using this function, the DLR/S independently determines which ballasts (DALI device/DALI address)
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 the system has to be modified, the Detect devices function must be
executed again.
The process does not need to be repeated when exchanging a DALI device with the same address. The
new DALI device contains the old DALI address and assumes the position of the DALI device it replaced.
The Detect devices function can not only be triggered via the communication object Detect devices, but also
by pressing the S button in manual mode. Furthermore, this function can be triggered with the Software
Tool using the Detect devices button in the Options window.
