ALTENBURGER DALI SYSTEM OVERVIEW:

DALI - Digital Addressable Lighting Interfaces offer a new industrial standard in the lighting engineering field. The ALTENBURGER DALI Controls are particularly suitable for applications in multi-functional projects like office buildings, hotels and restaurants, conference centres, schools and universities, private homes, etc.

Its control is quite uncomplicated. With 5 standard pushbuttons a multitude of functions can be performed: a selection of different lighting scenes, individual dimming controls and switching,
master controls and switches as well as daylight dependent constant light controls. Each individual lamp with its DALI-ballast can be initialized and assigned. Additional programmers or programs are not required.

ALTENBURGER-DALI Lighting controls in combination with DALI electronic ballasts are increasing the flexibility of lighting systems as well as energy savings and the reduction of component and installation cost.

The DALI-interface combines dimming and switching functions via one common control wire. All DALI ballasts and DALI-converters can be addressed individually.

Within the same lighting circuits fluorescent lamps, compact fluorescent lamps, low-voltage halogen lamps or incandescent lamps can be controlled or switched independent of each other. A new configuration is subsequently possible without any physical changes in the installation.

Even faults at individual DALI-ballasts are indicated with a back indication.

ALTENBURGER DALI CHARACTERISTICS:

Uncomplicated operation with just 5 pushbuttons.
Dimming and switching of up to 4 lighting groups.
Master dimming and switching.
Easy programming of lighting scenes.
Assignment of a maximum of 64 lighting circuits to a maximum of 4 groups.
A complete system configuration can be performed with pushbutton keys.
No PC or notebook required.
Compact, easy to survey components.
Just one DALI-control wire to addressable DALI-ballasts.
With a DALI-converter analogue electronic ballasts as well as electronic transformers with 1-10V interface and phase-controlled or phase-interval controlled dimmers can be integrated.
A fault indicator signals faults for individual lamps or ballasts.

DALI Functions:

Free assignment of a maximum of 64 circuits (max. 4 groups) Check-up on the assignment of individual ballasts and lamps to their groups after the completion of the assignment phase.
Individual dimming and switching of the different groups.
Master control (dimming and switching) of all circuits.
Storage and selection of lighting scenes.
Preliminary functions to be performed on site for an immediate dimming and switching operation after the installation.
3-fold constant light control (daylight-dependent control of 3 lighting groups) independent of each other.
Automatic identification of connected light sensors (if a light sensor is connected the assigned group automatically goes into the constant light control mode.)
If the presence detection is connected the first lighting scene is selected as soon as a movement is detected.
If presence is no longer detected the lighting is dimmed down within a pre-selectable time range and finally switched OFF.
If no light sensors or presence detection units are connected, the DALI control operates as a scene control.

SYSTEM COMPONENTS:

DALI CONTROLLER BASIC MODULE:

The DALI-controller basic is the main component of the  ALTENBURGER Digital Lighting Control system. Within the DALI wiring all DALI ballasts as well as the non-DALI-circuits being served by the converter are connected to this controller. Within the integrated scene control up to 4 scenes with 4 groups each can be stored and selected with the programmable scene selector panel (3-5 pushbuttons).

On selection of scene 1 the lighting groups 1-3 are operated as constant light controls if they are connected to the light sensor. Scene 2-4 are selectable dimmer scenes. If the presence detector is connected to the system, scene 1 would be selected as soon as a movement is detected. If no movement is detected, the lighting is dimmed down within a presettable time range of between 1 minute to 30 minutes, (can be adjusted at the controller) and at the expiration of this preset time period, the lighting will be switched OFF.

DALI-CONVERTER MODULES:

DALI-Converters are components which are able with their DALI interface, to convert analogue signals (e.g. 1...10V / 0...10V) into the required digital signals. Thus they can integrate existing installations like electronic analogue ballasts with 1-10V interface, electronic transformers for low-voltage halogen lamps with 1...10V interface, phase-controlled or phase-interval controlled
dimmers with 0...10V interface etc. into the DALI-system. The converter has, like any DALI ballast, an address. All analogue ballasts or dimmers from a single connected group are assigned to the converter (see components of the systems and their functions.).

CONVERTER MODULE TYPES:

The KDK 1...10V is a slim compact component with metal housing for integration into a Master Luminaire. The  load contact is internally connected to the phase. The control characteristic is adjusted to the 1-10V interface of the analogue ballasts or transformers.

The DK 1...10V NV is a component with snap on fastening and isolating housing for DIN-rail systems. Its load contact is voltage free. The control characteristic can be pre selected on the integral switch, so that a combination of electronic ballasts or transformers, with 1-10V interface, as well as with dimmers with an interface of 0... 10V is possible.

Both types of converters have an additional pushbutton input terminal, to allow for a single pushbutton "dim" function, without digital control via DALI. Please see wiring diagrams.

SYSTEM FUNCTIONS:

INITIAL FUNCTIONAL TEST, AFTER ON SITE INSTALLATION:

After all DALI-ballasts and components have been wired and the pushbutton panel has been connected to the DALI controller the first functions can be adjusted and tested on site. All
components are commonly switched.

CIRCUIT ASSIGNMENT TO RESPECTIVE GROUPS:

The individual circuits are assigned to 1 of 4 groups. Via the specified pushbutton sequence, group assignments are achieved. The currently selected lighting circuit is indicated, via that circuit's lamps in flashing mode. This indicates that they are assigned to the selected group. As soon as all light circuits are assigned, the group assignment can be checked and, if required, changed.

ADJUSTMENT OF A SPECIFIC GROUP TO SPECIFIC LIGHTING LEVELS:

After the assignment of circuits to the different groups, the individual groups can be switched or dimmed independently of each other.

E.g. If  group 1 must be switched, On / Off, or dimmed to a specific level of light, group 1 is then selected by means of a sustained press of pushbutton 1. With the "Master Pushbutton" then, the group is switched ON or OFF by means of a brief touch, or, with a longer touch of the "Master Pushbutton" the selected groups light intensity, is raised or lowered, (1-pushbutton function.)

If the other groups are to be switched or dimmed, the group selection is made by selecting the respective pushbuttons 2, 3 or 4. In conjunction with the "Master Pushbutton" the respective groups can then be switched or dimmed to their individual requirements. If no particular group is selected by the "Master Pushbutton" all groups are commonly, switched or dimmed (master function or preliminary - on site - function).

STORAGE AND SELECTION OF LIGHTING SCENES:

After the brightness of each group has been set to a certain level with the "Master Pushbutton" the respective light level for each group can be stored by pressing the buttons 1-4 for a few
seconds each. The stored scenes now can be selected by a brief touch via the buttons 1-4. With the "Master Pushbutton" the groups  can commonly be dimmed or switched. Also, after the selection of a scene, each group can individually be dimmed and switched.

CONSTANT LIGHT CONTROL:

If (maximum of 3) light sensors are connected, groups 1-3 can be operated individually within scene 1 as constant light controls. In this case artificial light is added to the natural light
level, but only up to the pre-selected constant light level. If only one light sensor is connected to the DALI-controller, the selected group (sensor 1 = group 1, sensor 2 = group 2, etc.)
is dimmed to the pre-selected light level after selection of scene 1. If in scene 1, groups 1-3 are to individually, be kept at pre-selected and constant light levels, each group then, would require one light sensor to be connected.

Groups 1-3 can also, jointly, within a pre-selectable constant light level, be controlled with just one light sensor in common to all groups. In this case just 1 light sensor is connected to all sensor inlets at the DALI-controller. If light sensor inlets are not wired into the system, the respective groups are then only, dimmable (no constant light control.)

PRESENCE DETECTION:

A presence detector is automatically identified by the DALI controller when connected. The DALI controller automatically selects scene no. 1 immediately after the recognition of any movement. Also, if light sensors are connected to the system, the respective groups automatically operate in scene 1 as constant light controls. If no movement is detected, the lighting is dimmed down within a presettable time range of between 1 minute to 30 minutes, (can be adjusted at the controller) and at the expiration of this preset time period, the lighting will be switched OFF.

If within the automatic 30 minute process, a group is switched or dimmed, or another lighting scene (2-4) is selected, the constant light control mode is paused. The new control mode is maintained for as long as movement is recognized, or that the pre-adjusted time range has not
expired. Subsequently lighting automatically is dimmed to 0 and switched OFF. If after the switch OFF state, a new movement is recognized, scene 1 starts from the beginning.
