DALI device types

When assigning DALI operating devices to groups and single devices in the course of DALI commissioning with the DCA, the DALI device type is always checked automatically. Here, the device type transmitted by the operating devices is compared with the functional scope of the projected group and single devices. The DCA only establishes an assignment if compatible device types correspond to the scope of functions (e.g. scope of functions group = "Brightness + Colour RGB" -> compatible device type must be "DT8", colour type must correspond to "Colour Control"). This prevents functional errors after commissioning.

Configurable functional scope of groups
Scope of functions groups	Group type	Compatible DALI device types	Use
Brightness	DIM	All	Only control the brightness
Brightness & colour temperature³	TW	Only DT8 with colour type "colour temperature (Tc)	Control of brightness and colour temperature
Brightness & colour RGB³	RGB	Only DT8 with colour type "Colour Control (RGBWAF)"¹	Control the brightness and colour in the RGB colour space
Brightness & colour RGBW³	RGBW	Only DT8 with colour type "Colour Control (RGBWAF)"²	Control brightness and colour in the RGBW colour space

Configurable range of functions for single devices
DALI device type Single device	Compatible DALI device types	Use
DT0 (fluorescent lamp)	only DT0	Only control the brightness
DT2 (discharge lamp)	only DT2	Only control the brightness
DT3 (LV halogen lamp)	only DT3	Only control the brightness
DT4 (incandescent lamp)	only DT4	Only control the brightness
DT6 (LED module)	only DT6	Only control the brightness
DT7 (switchable only)	only DT7	only control of the switching state (DALI switching actuator)
DT8 (colour temperature)³	Only DT8 with colour type "colour temperature (Tc)	Control of brightness and colour temperature
DT8 (colour RGB)³	Only DT8 with colour type "Colour Control (RGBWAF)"¹	Control the brightness and colour in the RGB colour space
DT8 (colour RGBW)³	Only DT8 with colour type "Colour Control (RGBWAF)"²	Control brightness and colour in the RGBW colour space
Universal⁴	All	Only control the brightness

1: DALI operating devices of DT8 device type must correspond at least to the "Colour Control RGB" colour type. The extended DALI colour types "WAF" (White [W], Amber [A], Freecolour [F]) can be assigned, but these are not supported.

2: DALI operating devices of the DT8 device type must correspond at least to the "Colour Control RGBW" colour type. The extended DALI colour types "AF" (Amber [A], Freecolour [F]) can be assigned, but these are not supported.

3: The device types "DT8 (colour temperature)", "DT8 (RGB colour)" and "DT8 (RGBW colour)" can be configured only if the integration of DT8 operating devices is intended.

4: The DALI device type "Universal" can be configured only for single devices if the integration of DT8 operating devices is not intended.

With the "central control" addressing type, no commissioning with the DCA takes place and consequently also no checking of compatible device types. In this case, when installing the DALI system, the installation engineer or system integrator must ensure that only DALI operating devices are installed that correspond to the projected scope of functions and can perform the intended functions.
