The DALI ADVANCED lighting control system DALI stands for "Digital Addressable Lighting Interface" and defines the digital communication protocol between DALI-compliant control gear (such as DALI ECG) and a control unit in a lighting system. DALI operates on the master/slave principle and simple communication optimized for lighting technology. This means that the central unit controls the flow of data on the data line. The ECG only respond when the central unit sends an appropriate request. Addressing is designed for 64 separate units that can be assigned to as many as 16 groups. Up to 15 lighting scenes can be stored. Thanks to DALI technology and the use of radio components, the functionality of the DALI ADVANCED lighting control system goes far beyond the simple switching and dimming of individual components in a traditional lighting control system. With the aid of the manual programming unit, the DALI side and the radio side can be programmed. All the necessary settings (such as group assignments) can be made and functions for the buttons on the controls can be defined. Once the system has been configured, it is operated by radio signals from the relevant radio transmitters (wall-mounted and hand-held transmitters, presence detectors or light sensors). For testing the system or for emergency system operation a standard push button can be connected to the extension terminals of the central unit so that central switching/dimming (on/off/dimming) can be performed. For a summary of the functions of the DALI ADVANCED lighting control system see the last page. page 2 Installation- and operating instructions: Central unit DALI RC ADVANCED CI 2. Groups and light scenes in a DALI system DALI is designed for scene-based lighting control systems. A scene, which means the lighting status of a room (Fig. 1), is defined by adjusting the different groups in the room. A group is a meaningful collection of luminaires. In offices, these groups are mostly rows of lights. Fig. 2 shows the four groups selected for the room in Fig. 1. Different lighting moods (scenes) can be created by setting different lighting levels for these groups (on, off or dimmed). These scenes can be easily saved and called up at any time at the touch of a button. They can also be adjusted at any time. Up to now, groups have been set up by wiring the circuits appropriately. Planners and installers had to decide right at the start which luminaires were to be combined into groups. With DALI this restriction is a thing of the past. The luminaires and their associated control gear can be freely assigned to groups, irrespective of their physical arrangement in rows. The group assignments, like the scenes, are stored in the DALI control gear.

Schematic diagram of DALI ADVANCED All the DALI control gear (DALI ECGs) are connected to the central unit by cable; all the other components are connected by radio links. The DALI central unit translates the radio commands according to their assigned functions and forwards them to the DALI system. Additional modules, such as the louvre blind module or the universal dimmer, are addressed directly by the radio transmitters (e.g. remote controls or the wallmounted transmitter). Therefore this modules can be used as stand alone components without a central unit or a programming tool. To put the central unit into operation you need a manual programming unit type DALI HPT ADVANCED. page 4 Installation- and operating instructions: Central unit DALI RC ADVANCED CI 4. Notes on installing the central unit The central unit is operated almost exclusively by radio signals. For this reason, the following points should be considered when planning an installation based on a DALI system and when installing the central unit: A non-exclusive transmission path is used for radio transmission, which means that interference cannot be ruled out. • Radio transmission is not suitable for safety applications, such as emergency shutdown or calls to the emergency services. • The central unit must be installed so that the distance between it and the various radio components is not too great for the local conditions. • If the DALI system extends over a number of rooms or floors, a radio path test must be performed in the rooms before the system is installed This should show how well the radio signals penetrate the walls and ceilings, and whether the signals reach the units furthest away. • The central unit must not be installed on metal or in metal distribution cabinets. • Do not install the central unit in suspended ceilings with metal cladding. • Ensure that the antenna is at least 3 m away from the antennas of other radio equipment such as cordless telephones or cordless headphones. • Make sure the unit is at least 10 cm away from metal surfaces (such as doors and walls). • Make sure the unit is at least 50 cm away from electrical equipment that emits high-frequency interference (such as computers, audio and video equipment, microwave ovens and electronic control gear). • Optimum reception is guaranteed only if the antenna is pulled out of the central unit and properly aligned. • Minimal distances: - 3 m away from the antennas of other radio equipment such as cordless telephones or cordless headphones. - 10 cm away from metal surfaces (such as doors and walls) - 50 cm away from electrical equipment that emits high-frequency interference (such as computers, audio and video equipment, microwave ovens and electronic control gear). The range of the builtin transmitter of approx. 20m (up to 100 m in the open) depends on the nature of the building: Dry material Wood, plaster, plasterboard Brick, MDF Reinforced concrete Metal, metal grating, aluminium cladding Penetration approx. 90 % approx. 70 % approx. 30 % approx. 10 % Installation- and operating instructions : Central unit DALI RC ADVANCED CI page 5 5. Safety and installation information • The unit should be installed and tested only by a qualified electrician. • Power to the units must be switched off before any work is undertaken. • The relevant safety and accident prevention regulations must be observed. Installation: Select a suitable site (taking into account the information in section 4) Feed the antenna cable out through the slit at the back of the casing Loosen the screws on the cover of the connection casing and remove the cover Fasten the central unit with two screws through the fixing holes Puncture the cable penetrations with a sharp instrument (such as a screwdriver) Loosen the cable clamp screws and then feed the cable through the cable penetrations into the casing Connect the cables in accordance with the wiring diagram (see below). Terminals are duplicated for possible through-wiring Tighten the cable clamp screws Carefully align the cable penetrations Place the cover on the unit, tighten the screws, and straighten the antenna for best reception Please cut the wired antenna if an optional external antenna is used Connection compartment: G N L Connection for standard push button page 6 2 x DALI connection integrated antenna optional external antenna Installation- and operating instructions : Central unit DALI RC ADVANCED CI 6.
