12 Helvar 478 8-Subnet DALI Controller: Installation and User Guide
DALI channel selected
If a DALI channel is selected, these messages are displayed:
Message
Reason
DALI BUS SHORTED
Either:
DALI channel terminals are short circuited;
Or:
Too many devices have been connected to a channel (and too much current
is being demanded from the 478).
Note:
The 478 also reports DALI lamp failure on the DALI control input. If no devices are connected to an output, it will
report back DALI lamp failure. This makes it easy to detect disconnected outputs.
