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 as a 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 failed
ballast from the DLR/S and can assume the functions of the failed DALI device, should it have the same
technical characteristics.
Note
The parameter Enable automatic DALI addressing in the
enabled for this purpose.
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 DLR/S.
The DLR/S assigns the first free DALI address to the new DALI device. If the new DALI device has a DALI
address which is already used in the DLR/S, one of both DALI devices with the same address will be
assigned a new and unused DALI address. In this way, the fault-free DALI device, which is already on the
DLR/S, may receive a new address.
Using the Software Tool, a correction or exchange of the DALI address, along with the assignment to a
lighting group, can be implemented in a simple manner by Drag and Drop even without using ETS.
