Description of the inputs and outputs

On the DALI output up to 64 devices can be connected with a DALI interface. The DGN/S is a DALI master
with integrated DALI power supply.
Important
Other DALI masters may not be connected to the output of the DGN/S.
The connection of another master to the single master system can cause communication malfunctions.
Caution
Other DALI power supplies may not be connected to the output of the DGN/S.
The connection of further DALI supply voltages may destroy the DGN/S due to voltage summation.
Connection of 230 V mains voltage to the DALI output will destroy the DALI end stage and the DALI
output.
A control line on the DALI output with the following maximum length can be used:
Cable length [mm
Max. cable length [m] from the DGN/S to DALI device
These values are rounded off and relate to the resistance values. EMC influences are not considered. For
this reason, the values should be considered as absolute maximum values.
It is possible to assemble the DALI control cable with conventional installation material for mains cables.
The two cores of the five-core NYM 5 x 1.5 mm
tion of the polarity. It is not mandatory to lay a separate control cable.
The isolation between DALI control cables and the power supply is assured by the simple insulation prop-
erties according to EN 410. SELV properties are not featured.
The device is ready for operation after connection of the gateway operating voltage. The green operating
LED on the front of the device lights up.
The yellow flashing (10 Hz) DALI LED indicates the maximum 90 second initialisation phase of the DGN/S.
The DALI system environment is analysed in this phase. If required, new DALI devices are allocated a
DALI address and can be assigned to a lighting group with the DALI-Software-Tool, whereby the lamps
are integrated into the KNX building automation. During this phase, it cannot be guaranteed that an incom-
ing telegram will be processed.
Note
The initialisation phase will not end if more than 64 DALI devices are connected.
The initialisation phase starts automatically after download, gateway operating voltage recovery and KNX
voltage recovery.
The initialisation phase is undertaken if in the parameterization Enable automatic DALI addressing has be-
en deactivated.
