DALI Controller
In many fields of application, dimmable lighting systems are becoming more and more important. The previous gap in
communication existing between the LON network and the lamps is closed by DALI. This Digital Addressable Lighting Interface
is a standardised interface for electronic ballasts developed by the leading European manufacturers.
By means of ballast addresses, the lamps of up to 64 DALI ballasts can be switched and dimmed individually via a common
data line – without the usual brightness gradient due to the resistance of the control line.
The DALI ballasts can be divided into up to 16 groups. Every ballast provides16 scene memory units for light levels so
particular atmospheres can be recalled directly.
LON DALI Controllers DR-S 4DIM, 8DIM and 16DIM allow independent control of four, eight or 16 lighting groups respectively,
according to the LonMark profiles. In addition, they provide the scene control of the DALI devices. Different characteristic
curves of dimmable electronic ballasts from various manufacturers are conformed to automatically.
The LON DALI Controllers are DALI system devices. They control all DALI ballasts and connected DALI multisensors, and
provide an interface between LON and the DALI bus. By use of the familiar LNS plug-in, the controllers can be configured and
the DALI devices can be integrated completely in the LON bus system. Neither special accessory devices, nor software, are
required.
The electronic DALI ballasts communicate bi-directionally, i.e. they can propagate their current state to other DALI devices. In
combination with the appropriate equipment, lamps can announce failures to the LON DALI Controller. The latter transmits the
message via the LON network to a building management centre or via a LON TCP/IP gateway to any other place in the world.
Up to 256 devices, divided into 64 DALI groups, can be connected to the LON DALI Gateway REG 4x16 DIM with four DALI
control lines.
