Index

L‑DALI Controllers are multifunctional devices combining constant light control, sunblind control and gateway functions between DALI (Digital Addressable Lighting Interface) and BACnet or Modbus systems. With Alarming, Scheduling, Trending and e-mail notification (AST™) the L‑DALI Controller is a perfect solution for DALI lighting systems and for a smooth DALI integration into BACnet or Modbus networks.

Built-In or External DALI Power Supply

The LDALI‑ME201-U comes with a built-in DALI power supply. It can supply one DALI channel with a guaranteed supply current of 230 mA. The DALI bus power can be switched on and off via web interface or LCD UI.

Thanks to the switching power supply, the device can handle input voltages from 85 – 240 V AC, 50/ 60 Hz. The LDALI‑ME204-U needs an external DALI power supply to power up the DALI network. Power supplies are available for up to four channel DALI networks.

BACnet Connectivity

The L‑DALI Controllers feature connectivity in BACnet networks via BACnet/ IP or BACnet MS/ TP. They also provide data exchange through Global Connections and support comprehensive AST™ functionality (Alarming, Scheduling, and Trending). Full L‑WEB integration is supported as well. The L‑DALI Controllers are equipped with two Ethernet ports including a built-in Ethernet switch.

IoT Integration

The IoT function (node.js) allows connecting the system to almost any cloud service, either for uploading historical data to analytics services, delivering alarm messages to alarm processing services or operating parts of the control system over a cloud service (e.g., scheduling based on Web calendars or booking systems). Processing Internet information such as weather data in forecast-based control is also possible. Finally, the JavaScript kernel also allows implementing serial protocols to non-standard equipment in primary plant control.

Local Operation and Override

The L‑DALI Controllers come with a built-in backlit display (128x64) and a jog dial for local operation and override. Using the local operation, maintenance tasks (DALI device replacement, burn-in mode, etc.) can be executed without the need of any software tool.

Constant Light Control

The integrated Constant Light Controller works with DALI and with BACnet devices. It supports various lighting control strategies, presence and lux level based. Several parameters can be used to configure the Constant Light Controller for almost any use case.

Sunblind Control with Constant Light Control Interaction

The integrated Sunblind Controller application allows intelligent controlling of blinds connected via SMI (requires LSMI-804). It offers effective sun and anti-glare protection through active slat control and slat adjustment according to the sun position. Energy efficiency is ensured by linking room occupancy with sun protection. If a room is unoccupied, the L‑DALI Controller opens or closes the sunblinds depending on the thermal requirements. This allows for instance to use the heat of the sun for heating in winter while in summer, the heat from the sun is reduced by the closed blinds to reduce the cooling load.Optionally, the sunblind and light control applications of a room or an area can be linked together. As both applications control the light available in the room this holistic approach assures maximum comfort and energy efficiency. In addition to the constant light and sunblind control, any mathematical calculation and function or logical operation (Boolean algebra) can be created on the device and process all available data points.

Device Configuration via Tool or Web Interface

The device configuration, commissioning, and parameterization is done either with the configuration tool software or via the integrated web server.

EnOcean, OPC and Modbus

EnOcean sensors and buttons can be integrated via the optional L‑ENO EnOcean interface. To use the L‑DALI with an existing SCADA solution all run-time values and parameters can be accessed via BACnet, OPC (XML/DA and UA) and Modbus TCP.

Advanced DALI Functions

  • DALI Sensors
    The L‑DALI Controllers support the integration of DALI multi-sensors for presence detection and light level recognition. In addition to the LOYTEC DALI multi-sensor LDALI‑MS2, DALI sensors of well-known manufacturers can be selected from a list of tested devices.
  • DALI Push Button
    For manual operation, DALI push button coupler and IR remote controls can be integrated into the system. Their functionality can be configured individually. In addition to controlling lighting via DALI (dimming, scene recall, etc.) also commands can be sent into the building network with a single keystroke.
  • DALI Relay Modules
    Standard loads in the power grid can be controlled via DALI using DALI Relay Modules.
  • Auto Burn-In for Fluorescent Lamps
    Fluorescent lamps must be operated about 100 hours with 100 % brightness before they may be dimmed. This burn-in process is monitored by L‑DALI for each lamp. After 100 hours burn-in time, the lamp’s constant light control is enabled.
  • Automatic Test of Emergency Lighting Systems
    In DALI emergency lighting systems, L‑DALI can be used for testing the system. The results can be logged.
  • Collection of Important Operational Parameters
    For maximum transparency in the lighting system, L‑DALI can record the operating hours of each lamp and also the energy consumption (calculated).
  • ldali ME204 U DALI.pngDALI Device Replacement made Easy
    Defective DALI ballasts can easily be replaced directly on the L-DALI Controller (LCD and jog dial) or via the Web interface. No software tool is necessary.

Smooth DALI integration into BACnet and Modbus Networks

The L‑DALI Controller maps information from the DALI network to BACnet objects or Modbus registers that are used to control DALI ballasts or to display operating states.

DALI Network Interface

L‑DALI represents a DALI-Master in the DALI network which can interact with selected DALI multi-sensors in Multi-Master mode. The LDALI‑ME204-U device is equipped with 4 independent DALI channels. The LDALI‑ME201‑U device is equipped with 1 DALI channel. Up to 64 DALI-based luminaries per DALI channel can be controlled individually or via 16 groups. All luminaries are monitored for lamp or ballast defect.

BACnet Interface

The following BACnet server objects are supported:

  • Analog Output objects to control DALI ballasts, groups, and channels
  • Multi-State Output objects for scene control of DALI groups and channels
  • Analog Input objects providing feedback from DALI ballast, groups, and channels
  • Analog Input objects providing status information from DALI groups and channels
  • Accumulator objects providing estimated energy usage of DALI groups and channels
  • Multi-State Output objects to issue commands (start/stop emergency test or burn-in, change color temperature, etc.) to DALI ballasts, groups and channels
  • Analog Input objects providing battery status of emergency ballasts, groups
  • Analog Input object providing lux level information from supported DALI sensors
  • Binary Input objects providing occupancy information from supported DALI sensors
  • Loop objects providing constant light controller functionality
  • Binary Input objects providing button information from supported DALI buttons
  • Various objects to control sunblinds

All data points are available on the web server in a tree structure and can be displayed and set via a web browser.
