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.

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 ).

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.

WRITE ERROR
After writing the parameters, if the load connected to the device flashes continuously at a frequency of 2 times per second when it is turned ON again, it means that the writing was not successful. Therefore, you will need to perform the following steps:
1. Turn OFF the device. 2. Perform a parameter rewrite. 3. Wait for the write to be successful or for no error messages to appear. 4. Turn the device back ON. If that doesn't work, you can perform a factory reset by quickly turning the device OFF and ON 6 times.

CONTROL TYPE
The PUSH-ON OFF DIM control type allows switching on/off and dimming via N.O. switch in the manner described in the §Local Command: pushbutton paragraph. Below are the parameters that can be set for the local command.

Power-On level: this is the intensity value to which the output is brought as soon as the device is powered.
Last Level: Enables the memory function. The Power On level will be the last level assumed before the power supply was removed.
Push-On level: this is the intensity value to which the output is brought when the device is accessed by means of a button.
Last Level: Enable the memory function. The power level will correspond to the last level assumed before the device was turned off by the button.
Dimming speed: This is the time it takes to adjust the light from 100% to 0% and vice versa.
Double-push delay: Allows you to set the speed at which you need to perform the quick double press.

DALI PARAMETERS
Through LightApp© it is possible to set the following functions as shown in a reduced version in the image.
DALI Firmware: Identifies the DALI firmware version currently loaded on the device (non-editable field). GTIN: unique DALI code of the product (non-editable field). Identification Number: Serial number of the microcontroller (field cannot be modified). Open Circuit Detection: Enables or disables output open-circuit detection (refer to §Open Circuit and Short Circuit Detection).

Device Manual

Made in Italy

Minimum Level: sets the minimum level of light intensity that can be reached by remote control (default value = 1).
Maximum Level: sets the maximum level of light intensity that can be reached by remote control (default value = 254).
Power-On level: this is the intensity value to which the output is brought as soon as the device is powered.
Mask: Enables or disables the audit.
System Failure Level: this is the intensity value to which the output is brought when a system failure occurs.
Mask: Enables or disables the audit.
Fade rate: indicates the rate (in steps/second) at which the output changes in brightness when the UP and DOWN commands are received.
Fade time: allows you to set the time it takes for the output to make a transition from one level of light intensity to another.

Group 0-15: allows you to associate the device address with one or more groups.
Mask: Enables or disables the audit.
Scene 0-15: allows you to associate the device with one or more scenes. Mask: Enables or disables the audit.

OPEN CIRCUIT AND SHORT CIRCUIT DETECTION
Using the Lamp-Failure command, the DALI protocol allows you to detect situations where the LED load connected to the output of the MINI-1AC-DALI may not work as expected, such as an incorrect connection (detecting it as an Open Circuit error) or a defect in the LED load (detecting it as a short circuit).
Enable/Disable Open Circuit Function: If a very small load is connected to the dimmer output, false open circuits may be detected in some cases. In this case, it is recommended to disable the Open Circuit detection function.
Enable/Disable Short Circuit Function: If a load with a high in-rush current is connected to the dimmer output, false shorts may be detected in some cases. In this case, it is recommended to disable the Short Circuit detection function.
