This group object is enabled if the Enable Group object "Lamp/ballast fault" parameter is set to Yes in the X Fault template
(group x/ballast x) parameter window, p. 95.
In the A output, Group x/Ballast x Fault parameter window you can define whether a lamp fault, ballast fault or lamp/ballast
fault is displayed.
Telegram value
Function
Lamp/ballast fault
Dependent on parameter
1 = Fault (depending on the setting – lamp, ballast, lamp/ballast fault)
For groups: at least one device in the group has a fault.
0 = No fault
Note
Lamp fault must be supported by the DALI device. 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 a lamp fault is only determined or signaled by the gateway when the lighting equipment should be
switched on. Therefore the gateway cannot signal a fault in advance.
Ballast fault is determined by the gateway. 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, registering not only the
number of devices but also their DALI addresses. If the system is changed, the Monitor DALI addresses option must
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.
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 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.
