DALI Device Type refers to classes of operating devices, for example ballasts for fluorescent tubes or drivers for LEDs. For each type the standard has been adjusted to include type-specific functions and commands.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

[\/vc_toggle][vc_toggle title=”What are the minimum requirements for a DALI system?” style=”simple” size=”sm”]<\/p>\n

\n

The basic conditions of a DALI circuit are the cable length (300m with 1.5mm2 cable cross-section), the number of individual addresses (64) and the maximum power requirement of a DALI circuit (250mA).<\/p>\n

\n
\n

The simplest DALI system consists of a DALI bus supply<\/a><\/span>, a DALI operating device<\/a><\/span> for example an LED driver and a DALI control unit<\/span><\/a> (DALI MC<\/a>+<\/span>, DALI ROT<\/span><\/a>, ect.).
\n<\/span>If you want to control several operating devices individually, the devices have to be addressed during the installation setup, which can be done with DALI USB<\/span><\/a> and the PC Software DALI Cockpit<\/span><\/a>.<\/p>\n

[\/vc_toggle][vc_toggle title=”What are the advantages of DALI compared to 0-10V control technology?” style=”simple” size=”sm”]Each DALI device can be assigned an address and thus individually controlled. Groups of operating devices can be created and controlled together via group commands without the need for any changes to the wiring. Due to the software configuration of the entire system, the installation costs are significantly lower. Due to the digital signal transmission, voltage drops on the control lines are irrelevant and all operating devices reliably receive the same setpoint. In addition, the status of each operating device can be queried and various settings can be stored in the operating devices. A DALI system thus offers better quality and more reliability and easier maintenance at lower costs.[\/vc_toggle][vc_toggle title=”Is it also possible to control more than 64 control gears via DALI?” style=”simple” size=”sm”]There are 64 DALI short addresses per DALI circuit. With a DALI Expander<\/span><\/a>, the number of operating devices can be increased. Up to 64 additional operating devices can be connected to the expander output, which are controlled together via the DALI address of the expander. So theoretically 64 times 64 bulbs could be controlled. The DALI Expander3<\/span><\/a> or the wDALIGroupController<\/span><\/a> offer similar possibilities.[\/vc_toggle][vc_toggle title=”Can a control gear belong to several groups? If so, which group has the highest priority?” style=”simple” size=”sm”]<\/p>\n

\n
\n
\n

Each control gear can be added to each of the 16 groups. All groups are equal in their priority. The last valid command sent to the control gear directly or to the group has the highest priority.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
