This group object is enabled if the Enable Group object "Ballast fault" parameter is set to Yes in the X Output: Fault parameter
window, p. 57.
This group object sends or reads a ballast fault.

A ballast fault can occur in one of the following situations:

Function
Lamp fault
Dependent on parameter
1 = Lamp fault
(at least one connected DALI device has sent a lamp fault)
0 = No lamp fault
Note
This function must be supported by the DALI device and sent via DALI by the gateway on request.
Using DALI devices that do no not monitor their lamps and therefore do not provide this information on the DALI
means that the gateway cannot detect a lamp fault. The Monitor DALI addresses function need not be explicitly
activated in order to monitor a lamp fault.
In most cases the gateway only determines or signals a fault when the lighting equipment should be switched on.
So the gateway cannot signal a fault in advance.
Ballast fault
Dependent on parameter
1 = ballast fault (at least one connected ballast has a fault)
0 = No ballast fault
The ballast malfunctions and does not send telegrams on the DALI control line.
The ballast has no ballast supply voltage and does not send telegrams on the DALI control line.
The DALI control line to the ballast is interrupted and the gateway does not receive a status response.
The ballast has lost its address and a query from the gateway remains unanswered.
Note
To ensure that ballast faults are correctly evaluated, the gateway needs to know how many DALI devices require
monitoring. This is done by one-time activation of the Monitor DALI addresses group object (no. 8). Using this
function, the gateway independently determines which DALI devices (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 the system is changed, the Monitor DALI addresses option has to be reactivated.
The process need not be repeated when exchanging one DALI device with the same address. The new DALI device
contains the old DALI address and adopts the position of the DALI device it is replacing.
The Monitor DALI addresses function can be triggered either by the group object of the same name or by
®
the i-bus Tool via the Monitor all DALI addresses interface in the DALI window.
