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.
