TYPE OF LOAD
The following table shows the types of loads that can be connected to the output of the MINI-1AC-DALI.

POSITIONING THE TC POINT
The following figure shows the positioning of the maximum temperature point (Tc point, highlighted in red) reached by the electronics inside the enclosure. It is located on the front side (Top) near the connector of the LED outputs.

INSTALLATION

WARNING! Installation and maintenance must always be carried out in the absence of voltage.
Before proceeding with the connection of the device to the 230 Vac mains, make sure that the mains voltage is disconnected from the system.
The device should only be connected and installed by qualified personnel. All applicable building regulations, legislation, rules, and codes must be complied with. Incorrect installation of the device may cause irreparable damage to the device and connected loads.

The following paragraphs show the diagrams of the connection of the dimmer to the remote control, the load and the supply voltage. It is recommended that you follow these steps to install the product safely:

1. Load wiring: connect the load to the “AC OUT” terminals respecting the technical data of the load, with the neutral of the load at the terminal with the symbol “N” and the phase at the terminal with the symbol “OUT”.
2. Local control wiring: connect the N.O. button to the “IN” and “N” terminals of the “PUSH” input respecting one of the wirings shown in the connection diagram in Figure 3.
3. Remote control wiring: Connect the DA data bus signals to the “DALI” terminals with the “DA” symbols.
4. Power supply wiring: Connect the 230 Vac @ 50 Hz mains power supply to the “AC IN” terminals respecting the Phase-Live (L) and Neutral-Neutral (N) convention to terminals “L” and “N” respectively.

LOAD CONNECTION

MINI-1AC-DALI has 1 output channel that can be driven independently (e.g. for AC modules).
The connection diagram on the side allows you to drive 1 AC load, on the AC OUT output channel.

CONNECTING THE LOCAL COMMAND
MINI-1AC-DALI can be controlled in manual mode via N.O button.

Figure 3 shows three different wiring possibilities for the local control: N.O. switch connected as a dry contact (for distances less than 10m), connected to Phase (L) or Neutral (N).

CONNECTING THE REMOTE CONTROL
MINI-1AC-DALI can be controlled remotely via DALI digital bus by means of a simple two-wire cable (non-twisted and unshielded). The control is carried out by means of a DALI Master that provides commands to the devices in the DALI network and, possibly, the power supply7 to the network itself. DALI supports several cabling topologies, including the bus wiring shown as an example in Figure 4.

To connect MINI-1AC-DALI to the DALI network, simply connect the bus cables to the “DA” terminals of the “DALI” terminal: as different topologies are possible, it is not necessary to respect the polarity of the “DA+” and “DA-” signals of the bus during connection.

7 Bus power can be supplied via an external 16 Vdc power supply (or within the range of 12 ÷ 20 Vdc) or by a DALI Master with integrated Bus power supply (e.g. DGM02-1248 shown in Figure 4). For more information, please consult our website: www.dalcnet.com ).

DALI CABLING TOPOLOGIES
DALI supports several cabling topologies, such as bus cabling, shown as an example in Figure 4.

The DALI-2 protocol supports up to 64 power slave devices (e.g. MINI-1AC-DALI) connected with different wiring topologies shown in Figure 5: bus, star, tree, or in-line. All other topologies are excluded.

POWER SUPPLY CONNECTION
MINI-1AC-DALI can be powered by 230 Vac @ 50Hz mains voltage and supplies the same voltage (dimmed in phase tray) to the output load. Once the load and remote control (DALI bus) are connected, connect the AC power supply respecting the Phase-Live (L) and Neutral-Neutral (N) conventions to the “L” and “N” terminals of the AC IN terminal.

LOCAL COMMAND: PUSHBUTTON
MINI-1AC-DALI has one input for N.O. pushbutton, through which different operating parameters can be managed. The connected button takes over control and adjustment of the output load: each action on the pushbutton activates a specific function listed in the following table.

REMOTE CONTROL: DALI PROTOCOL
DALI (Digital Addressable Lighting Interface) is a protocol developed by the DALI Alliance (DIIA) to allow the management, configuration and programming of LED lighting systems in digital mode: through a two-way communication process between devices and control units, it is possible to execute ON, OFF or dimmer commands, report faults or information of various kinds. Based on a Master/Slave architecture, the DALI standard allows both single digital control of devices and programming in groups and/or broadcast.

In its second version, DALI-2 allows first full compatibility with the earlier protocol, and secondly brings numerous improvements compared to DALI-1:

1. Addition of lighting control devices: e.g. buttons, sensors, and LED drivers that were not included in the earlier version. In addition, to obtain DALI-2 certification, the new protocol requires the execution of functional and compliance tests by DIIA.
2. Introduction of the Multi Master architecture: with the regulation of the various lighting control devices, it is possible to send commands and signals to the DALI-2 bus from multiple sources, easing independent, immediate, and simultaneous data communication.
3. Development of functional and application standards: new extensions have been drawn up for DALI-2 devices, e.g. for emergency lighting or colour control, creating a new product standard for smart lighting and IoT systems called D4i.

PROFILE MAPPING: OPERATION MODE
The DALI protocol provides two configurations depending on the light characteristics to be obtained through the LED module connected to the outputs. Each profile is composed of a defined number of 8-bit channels, whose values can be set in the range (0 ÷ 255), each of which stands for a light characteristic (e.g. brightness, colour, temperature, etc.) to be modulated on the LED load.
MINI-1AC-DALI supports only the DT6 profile to provide adjustment of the light intensity for the single output channel.

DT6 – 1 CHANNEL
The “DT6” profile allows you to adjust the light intensity for the output channel. In the §Type of Load section, it is possible to find details on the type of load and the most suitable connection diagram for this operating mode. It is understood that this profile can be used with all the other types of loads proposed in this document.

THERMAL CHARACTERIZATION

Figure 6 shows the maximum output current values that can be supplied by the MINI-1AC-DALI as a function of the operating temperature8 (or ambient temperature, TA) of work, summarized below:

• TA = (-10 ÷ +35) °C ⇢ IOUT ≤ 10 A
• TA = (+35 ÷ +45) °C ⇢ IOUT ≤ 8 A
• TA = (+45 ÷ +60) °C ⇢ IOUT ≤ 6 A

These maximum current values can only be applied under suitable ventilation conditions.

DIMMING CURVES

Figure 7 shows the dimming curves supported by the MINI-1AC-DALI. The selection of the curve can be done using the Dalcnet LightApp© app.

MECHANICAL DIMENSIONS

Figure 8 details the mechanical measurements and overall dimensions [mm] of the outer casing.
