DG/S 1.1, DALI-Gateway
A DALI power source (16 V DC) supplies the individual DALI devices, the
DALI processor, controller, control devices or modules which are responsible
for managing the scenes and groups in the DALI line.
A separate relay or a calculation of the switching capacity is not required.
The switching relay is integrated in the DALI ballast and matched to the load.
Noiseless switching is thus enabled.
There are DALI devices (e.g. LED converter, switch actuators) which consist
internally of several DALI devices and can only be addressed via a common
DALI control cable. The internal DALI devices have different individual DALI
addresses and can be addressed individually via DALI.
The DALI-Gateway DG/S 1.1 recognises every individual DALI
device in the DALI equipment. Each DALI device can be
monitored and controlled individually.
The DALI-Gateway DG/S 8.1 on the other hand can only control
all DALI devices on a single channel, i.e. the individual devices
on one device can only be controlled globally.
The following behaviour is defined in the supplied state of the DALI devices:
when the operating voltage of the DALI devices is interrupted, the connected
luminaire fails. On mains voltage recovery, the luminaire is switched on
again with 100% brightness. The electrical installer can thus switch the DALI
lighting on and off, e.g. with an automatic circuit-breaker, even if the
individual DALI devices have not yet been addressed.
