Exchange of DALI devices

If a DALI device fails in an existing DALI installation, where DALI addresses are assigned without any
gaps, a DALI device as provided in the default state from the factory (without a DALI address assignment)
can be used for replacement and will avoid the requirement for re-commissioning. The new DALI device
automatically receives the first free DALI address, group assignments and scene parameters of the faulty
ballast from the DGN/S and can assume the functions of the failed DALI device with the same technical
characteristics.
Note
The parameter Enable automatic DALI addressing in
enabled.
If multiple DALI devices on a DALI output fail or there are gaps in the DALI address assignment, it is not
possible to guarantee a unique assignment of the replacement device by the DGN/S.
The DGN/S assigns the new DALI device with the first free DALI address. If the new DALI device has a
DALI address, which is already used in the DGN/S, one of both DALI devices with the same address will
be assigned with a new and unused DALI address. In this way, the fault-free DALI device, which is already
on the DGN/S, may receive a new address.
With the DALI-Software-Tool, page Fehler! Textmarke nicht definiert., a correction or exchange of the
DALI address, as with the assignment to a lighting group, can be implemented in a simple manner by
"Drag and Drop" even without using the ETS.
