Dali Extension

The DALI Extension is designed to integrate lighting devices with DALI interface.

Datasheet DALI Extension

Table of Contents


The DALI Extension is installed on a DIN rail in a suitable enclosure.

Connect the power supply, Link communication to the Miniserver and the DALI data lines.

DALI bus topology can be daisy-chained, star or tree. Ring topology is not permitted.

The maximum cable length of the DALI bus is 300m using 1.5 mm² (AWG16) conductors.
When using the maximum cable length, it is recommend to run DALI separate from any mains voltage cables.
The maximum voltage drop must not exceed 2V.

The DALI Extension is equipped with a power supply for the DALI bus. If an external power supply is used, it is imperative that the correct polarity of the bus lines is observed. Also the supply of the DALI bus has to be deactivated in the properties of the DALI Extension in Loxone Config.

The Extension starts after switching on the power supply, and the status LED will flash orange after a short time when the connection to the Miniserver is established.

Then follow the pairing procedure

Adding DALI devices

For a new installation, a Fresh Installation search must be performed to assign an address to the DALI devices.

To search for Dali devices, first click on the Dali Extension in Loxone Config, and then activate Add Dali Device.

The search results at the bottom of the Loxone Config, will list all connected DALI devices:

Now select a device, enter a name and select a room, then click on Create device.

To apply the changes, save the program in the Miniserver.

Now the added devices are ready for use and available in Loxone Config.

Address assignment and options

Generally, the additional options are used for a new installation or address conflicts.

Option Description
Load factory setting All DALI devices are reset to factory settings during the search
Complete new installation All DALI device addresses are deleted and reassigned during the search
Visual confirmation DALI devices light up when they are found

If the DALI Extension is added to an existing DALI installation, a normal search is sufficient to find all DALI devices and their settings.

If a DALI device is added to an existing installation, a normal search is also sufficient to find the newly added DALI devices. Available addresses are assigned to the new devices.
Prerequisite: To avoid possible address conflicts, the newly added devices must not have an assigned address yet.

If an address conflict is detected, e.g. if two or more devices have the same address, the function "Resolve address conflict" can be used:

The affected devices are assigned a new address. If devices were already paired, they can be added via "Replace device".

Alternatively, you can also start a search with "Fresh Installation", where all device addresses are deleted and reassigned.

Create DALI groups

If several DALI lights are to be controlled simultaneously, a DALI group is recommended.
This offers the advantage that the programming is simpler and there is no time delay when dimming the lights. Also, central functions can be handled easier.

When pairing DALI devices, existing group assignments are imported and created in Loxone Config.

To create a new group, the DALI devices must already be paired.

The devices can be selected in the DALI group's properties, thus assigning them to that group.

The group actuator can then be used in programming.

Diagnostics for DALI devices

The option Display diagnostic inputs can be used to display an error input for DALI devices, that is active in case of errors.

Possible errors are: no bulb or defective bulb in the DALI device.

The DALI Monitor provides an analysis of the communication between the DALI Extension and devices. First connect to the Miniserver, click on the DALI Extension, and then on Dali Monitor.

The DALI monitor displays the name of the device, the transmitted values and the DALI commands.

These are defined in IEC 62386-102, the following is an excerpt:

Command Description
DIRECT_ARC_POWER Dimming value is sent (0-255)
CMD_QUERY_X A data set is queried from the DALI dimmer
This sets the current search address
COMPARE Prompts the dimmer to compare its own random number with the current search address
WITHDRAW Found dimmer is removed from the search
PROG_SHORT_ADR The DALI short address is stored in the dimmer
VERIFY_SHORT_ADR The DALI short address of the dimmer is verified
TERMINATE Search is ended

Safety Instructions

The installation must be carried out by a qualified technician in accordance with all applicable regulations.

The installation requires a suitable enclosure to ensure protection against contact, water and dust.

The device must not be used as part of safety-critical systems.
