Why does the controller tell me that there is another controller connected to the same DALI line?

If a installer inadvertently connected a line to two controllers, the controllers can end up fighting for control causing line noise and unexpected operations.

To mitigate this, we look for device type responses and will inform you when multiple controllers are found on a line. This will help speed up time debugging the unexpected operations.

Note: This notification is limited to those faults where the Positive and Negative terminals of one controller are connected to the Positive and Negative terminals of the second. If the polarity is crossed the fault may not be detected or may be detected as an overload or short circuit.
