1. Check that the DALI LEDs (“DALI x ACT”, where x is 1 to 4) do not light up red. If

one of these LEDs is red, check the proper connection of the bus power supply for the

corresponding channel and check the DALI wiring for short-circuits.

2. Press the DALI mode button (“ON/OFF/AUTO”) on the front panel of the L-DALI

once. Now all DALI ballasts should be switched on (maximum level) and the DALI

LEDs on the L-DALI should light up green.

3. Press the DALI mode button again. Now all DALI ballasts should be switched off and

the DALI LEDs on the L-DALI should light up orange.

4. Press the DALI mode button again. This should not change the state of the DALI

ballasts but return the L-DALI to the auto-mode (control via CEA-709/BACnet

interface).

3.1.2 Models with built-in DALI Bus Power Supply

Connect the L-DALI to the power and to the DALI network as shown in Figure 5. To allow

for easy configuration it is recommended to always connect the L-DALI to the Ethernet

network (if available). More detailed instructions are given in Chapter 4.

After the DALI ballasts have been installed and connected to the DALI network, the

installation can be tested by following these steps:

1. Check that the status LED (“status”) does not light up red. If the LED is red, check the

DALI wiring for short-circuits.
