Ballast and DIN-DALI-2 Replacement
The DIN-DALI-2 keeps a record of all ballasts it has commissioned, including all
ballast settings such as fade times and groups. If a ballast fails and a replacement is
installed, readdressing can take place from the front of the DIN-DALI-2 unit (no
laptop necessary).
Ballast Replacement
The following process allows one or more failed DALI ballasts to be replaced with
new ballasts. All addressing and programming is transferred to the new ballasts.
The DIN-DALI-2 controls two independent loops of DALI ballasts. Up to 64 ballasts
can be connected to each loop. Each ballast must be assigned a unique address
(0 – 63). Ballasts typically leave the factory with an “unassigned address” of 255.
The ballasts store information related to addressing, group assignments, presets and
fade times programmed during commissioning. When a failed ballast is replaced, all
of these parameters must be reprogrammed into the new ballast for it to function
correctly.
The DIN-DALI-2 simplifies the replacement process by keeping a copy of all
information within its own internal memory. The DIN-DALI-2 identifies that a
ballast is missing and discovers a new ballast on the DALI loop. The settings for the
missing ballast are transferred to the new ballast.
If there is more than one missing ballast, the installer must select the address to
assign to each new ballast. Refer to the following image for button location.
Replacing a Single Ballast
If there is only one ballast to replace, use the following simplified method.
