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 in the as-delivered state with factory settings (without DALI addressing) can be used as a
replacement, avoiding the need for re-commissioning. The gateway automatically assigns the new DALI
device the first free DALI output address, group assignments and scene parameters of the faulty ballast,
and the new device can assume the functions of the failed device as long as it has the same technical
characteristics.
Note
The Enable automatic DALI addressing parameter must be enabled in the A DALI configuration
parameter window.
If multiple DALI devices on a DALI output fail or there are gaps in the DALI addressing, it is not possible for
the gateway to guarantee a unique assignment for the replacement device.
The gateway assigns the new DALI device the first free DALI address on the output. If the new DALI
device has a DALI address which is already in use on the output, one of the two DALI devices with the
same address will be assigned a new and unused DALI address. This means that the existing fault-free
DALI device on the DG/S may be assigned a new address.
DALI addresses and group assignments can easily be corrected or exchanged without ETS by using
the i-bus
If automatic DALI addressing is not enabled, there is no need to enable it via ETS programming.
The i-bus
There is also the option of using the
trigger one-time DALI addressing which means that you can exchange a device without using any software
at all. The prerequisite for this is that the current DALI addressing has no gaps.
Note
Triggering DALI addressing via the i-bus
It simply triggers one-time DALI addressing which runs until all the DALI devices have a DALI address
and/or there are no duplicate DALI addresses detected. Duplicate addressing is also triggered if
applicable. If the one-time DALI addressing process has finished, automatic DALI addressing remains
latent if it is parametrized to do so.
