4.4 Replacement of DALI
devices
© 2006 ABB STOTZ-KONTAKT GmbH
Functional description
If only one ballast has failed and the DALI addresses are assigned without
any gaps (normally the case with DG/S 1.1), a ballast without a DALI
address (default state) can be replaced without commissioning. The new
DALI device automatically receives the free DALI address of the ballast from
the DG/S 1.1 and can assume the functions of the old device with the same
technical characteristics.
If multiple DALI devices on a channel fail, or there are gaps in the address
assignment, it is not possible to guarantee a unique assignment of the
replacement device by the DG/S 1.1. The DG/S 1.1 assigns the new DALI
device with the first free DALI address. If the new DALI device already has a
DALI address which is being used in the DALI-Gateway, one of the two
devices with the same address will be assigned an unused DALI address. In
this case, the error-free DALI device which is already connected to the
gateway may also receive a new address.
With the DGS11 Software Tool (see appendix), a correction or exchange of
the DALI address can be implemented in a simple manner by "drag and
drop" without using the ETS, and ensures that an arranged assignment is
possible.
