Display elements

On the front of the DALI gateway there is a green operation LED (ON) and a yellow DALI LED for each
output. The LEDs indicate the following:
ON
ON
•
Lights up green if the gateway supply voltage and KNX voltage is available and the device is ready for
operation.
•
Flashes quickly (5 Hz) if KNX voltage is available but the gateway supply voltage is not.
•
Flashes slowly (1 Hz) in manual mode.
•
Goes off if there is no KNX voltage and/or the gateway supply voltage fails.
DALI
•
Off if the gateway is in normal mode.
In manual operation it indicates the switch status of the DALI output instead of a DALI fault. If the LED
is off this means the output is switched off.
•
Lights up if there is a DALI fault, e.g., a short circuit, a lamp fault or a ballast fault.
•
Flashes quickly (5 Hz) during the initialization phase, which starts after download, KNX bus voltage
recovery or after elimination of a DALI short circuit. If more than 64 DALI devices are connected to
a DALI output, the device will not exit the initialization phase. The yellow LED will continuously flash.
Note
In manual operation the yellow DALI LED indicates the switch status of the DALI output instead of
a DALI fault.
