Lighting systems

SERVICE OVERVIEW

Lighting control based on DALI is to be operated via touch panels and should be integrated seamlessly into a BACnet system. DALI lights should be switched on and off and dimmed via BACnet touch panels or a BACnet based building management system. Additionally operation status and failure mode like lamp malfunction will be displayed.

The lighting system is established in DALI according to the specifications. With the LOYTEC LDALI-ME204-U 4 DALI segments, each with up to 64 DALI lamps, are operated. The lamps can be switched and dimmed separately, in groups or all together. Per 2 DALI segments additionally one DALI power supply LDALI-PWR2-U or for up to 4 DALI segments one LDALI-PWR4-U are established.

Integration of the DALI side easily happens through the built-in web server of the LDALI-ME204-U. For each DALI lamp or DALI group the LDALI-ME204-U provides dedicated analog output BACnet server objects on the BACnet side. These BACnet server objects  are used by the BACnet L-VIS touch panels, by BACnet controllers or by a BACnet based building management system to control the lighting system via BACnet. The BACnet objects provide lighting values plus the  operation status of the lamps through properties.
