c . Introduction: DALI standard Introduction: DALI standard History The agreement by the lighting industry to adopt a common protocol for digital addressable control of luminaires has opened up a virtually unlimited number of options for regulating artificial lighting in all applications. This common protocol is the DALI protocol (Digital Addressable Lighting Interface), which has now been internationally standardised through the IEC.
c . Introduction: DALI standard Features of DALI Simplified Installation Power lines and control lines can be laid together in the same cable. The wiring may be in series, in a star arrangement or in mixed form. No polarity There is no need to worry about the polarity (+/-) of the DALI control line. Stable dimming function All the luminaires receive the same interference-free digital signal and therefore the same dimmer value.
c . Introduction: DALI standard ½ CAUTION! When the maximum cable length is calculated the contact resistance must also be taken into account. A voltage drop of 2 V must not be exceeded! Scene and group concept DALI scenes With DALI it is possible to store 16 different lighting scenarios in each DALI unit so that predefined lighting moods can be called up for a room (for example the "presentation" scene in a conference room, or a "morning" scene in a wellness centre).
c . Introduction: DALI standard Positioning of DALI DALI is not a new system for building control such as LON, KNX and other building management systems but a useful addition for the practical application of lighting controllers. DALI provides ideal support for building control systems and enables each light source to be individually addressed. Even small installations in which a building control system would not be economical need not forego the convenience of digital technology.

c . Designing a DALI application Designing a DALI application This section is intended to simplify the planning and configuration of DALI installations. Using examples from the Application Guide it discusses the typical requirements of a DALI system and the special features of Tridonic products. The following two aspects deserve special attention when designing a DALI application.
c . Designing a DALI application Maximum of 16 DALI scenes per DALI circuit The current on the DALI circuit must not exceed the maximum current of the power supply (DALI PS/PS1 = 200mA or DALI PS2 = 240mA). The maximum cable length depends on the maximum permitted voltage drop along the DALI cable; this is defined as 2 V max. This corresponds to a maximum cable length of 300 m for a line cross-section of 1.5 mm²; contact resistance must also be taken into account. A voltage drop of 2V must not be exceeded.
c . Designing a DALI application Calculating the voltage drop The formula for calculating the voltage drop is as follows: Uv Voltage drop in V I Current in A (0.25 A) S Cross section in mm2 l Cable length in m γ Electrical conductivity in m / (Ω mm2), for copper cable: 56 m / (Ω mm2) I NOTICE The maximum current of 250 mA must be used for calculating the voltage drop. Example: DALI circuit with a cable length of 300 m and a cable cross-section of 1.
c . Designing a DALI application Wiring The following points must be considered: Figure: Typical texture of used wires DALI systems are installed using conventional wiring material for line voltage. Two wires are needed for the DALI control circuit. The line voltage and bus line may be routed in the same cable.

c . Start-up Start-up There are various ways of putting a DALI application into operation. Some of the comfortDIM products have the option of putting small (single-room) applications directly into operation. One of these products is the DALI GC. With the DALI x-touchPANEL it is easy to set up the parameters even for medium-size applications.
c . Start-up Sample set-up for a conference room This section uses the example of the conference room from Chapter 4 to show how a DALI application can be put into operation with the aid of masterCONFIGURATOR in six easy steps. The conference room contains 8 DALI luminaires, two DALI SC units, one DALI GC unit and one DALI Power Supply. The rotary switches on the DALI SC and GC have already been set to the correct position during installation.
c . Start-up Table: Parts list Pos.
c . Start-up Installation The DALI circuit is installed using standard installation material for mains voltage. The mains voltage and DALI line may be routed in the same cable. There is therefore no need for a separate bus line, but one can be used if required. Figure: Wiring diagram DALI USB is needed only for set-up with masterCONFIGURATOR and can then be removed. Installing and connecting DALI GC Standard switches can be used for installing DALI GC.
c .

c . Start-up Setting up without software An application with two DALI SCs and one DALI GC enables the installation to be set up without software. Step 1: Enter programming mode on the DALI GC (new installation) DALI GC switches to programming mode and addresses the DALI ballasts. After the addressing cycle the DALI ballast with the first address is switched to 100%, and all the others to the “Min.
c . Start-up Setting up with masterCONFIGURATOR The masterCONFIGURATOR enables the wiring of the DALI circuit to be tested, the devices to be addressed and the group and scene settings to be completed, all in 5 easy steps. The masterCONFIGURATOR has its own separate documentation (see Reference list). Preparation Before you can start setting up with masterCONFIGURATOR the DALI circuit must be linked to the computer via a DALI USB.
c . Start-up Select “Start Test” →The 8 DALI luminaires start to flash, which means that installation has been successfully completed.
c . Start-up Step 3: Testing the addresses Testing the addresses involves the devices being switched on one after the other with all the other devices switched off. The process is repeated when the last address is reached. This function can be used to check whether the addresses are assigned as required. Step 4: Grouping the devices In this step the various ballasts are assigned to the DALI groups.
c . Start-up (1) (2) (3) (4) (5) Show selection: The highlighted luminaire is switched to 100%, the others to the minimum fade value Group selection: Selection of the DALI group Device container: Available DALI devices Add/remove: Adds the highlighted device to the group or removes it.
c . Maintenance and troubleshooting Step 5: Assigning scenes In the “Assign scenes” step dimming values for the various DALI groups can be assigned to the 16 DALI scenes of the DALI circuit. Clicking on the “Assign scene” button transfers the values to the relevant ballasts.
c . Maintenance and troubleshooting Maintenance and troubleshooting Failure of a DALI ballast DALI is based to a large extent on distributed intelligence, which means that the addresses and parameters such as group assignment and scene values are stored in the DALI ballasts. If a ballast fails, these parameters must be reset in the replacement ballast. DALI ballasts straight from the factory are not programmed with any addresses, group assignments or scene values.
c . Maintenance and troubleshooting Measuring the voltage drop in a DALI circuit Proceed as follows: Check that all the DALI devices are functioning properly. Make sure there is no communication on the DALI line. Measure the voltage at the DALI power supply. » The value must be between 11.5 V and 22.5 V; a typical value is 16 V. » A much lower value may indicate a short-circuit. Measure the voltage at the DALI device furthest from the DALI power supply. » The value must be between 9.5 V and 20.5 V.
c . Maintenance and troubleshooting Example: Two DALI circuits with a voltage drop less than 2 V The DALI circuit is divided into two when a DALI repeater is used. The two circuits are now both below the maximum permitted DALI voltage drop of 2 V. The voltage drop must be measured in both circuits (at the two DALI power supplies). Two additional components are required – a DALI PS and a DALI repeater. ...
c . Maintenance and troubleshooting Double addressing problem at set-up In rare cases more than one DALI device may have the same short address. If a DALI command is sent to such a short address the devices will react simultaneously. It will not be possible to address just one device; all the devices with the same short address will always react together. It will not be possible to get the correct response from these devices.
