Built-In DALI Bus Power Supply

All L-DALI models come with a built-in DALI bus power supply. The LDALI-3E101-U and the LDALI-3E102-U can supply each DALI channel with a guaranteed supply current of 230 mA, the LDALI-3E104-U can supply 116 mA per channel. In case of the LDALI-3E104-U an external DALI bus power supply can be added to top up the supply current to 232 mA. External power supplies are available for up to four DALI channels. The internal DALI bus power can be switched on and off via web interface or LCD UI. Thanks to the switching power supply, these devices can handle input voltages from 85 – 240 V AC, 50/60 Hz.

LonMark TP/FT‑10 or Ethernet/IP‑852 Connection

The L‑DALI Controllers provide connectivity in LonMark Systems through IP‑852, or TP/FT‑10 as well as data exchange through Global Connections. They support comprehensive AST™ functionality (Alarming, Scheduling, and Trending) with e‑mail notification. 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.

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 (LonMark Functional Profile #3050) allows controlling local DALI ballasts and luminaires via the CEA‑709 network. 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 (LonMark Functional Profile #6111) allows intelligent controlling of blinds connected via SMI (requires LSMI-804) or the CEA‑709 network. 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 (used as stand-alone tool or as LNS® plug-in) or via the integrated web server.

EnOcean, OPC and Modbus

Wireless 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 runtime values and parameters can be accessed via OPC (XML/DA and UA) and Modbus TCP.

Advanced DALI Functions

  • DALI Sensors
    The L‑DALI Controllers support the integration of DALI-2 multi-sensors for presence detection and light level recognition. In addition to the LOYTEC DALI-2 multi-sensor LDALI‑MS2/MS2-BT/MS4-BT, DALI-2 sensors of many wellknown manufacturers can be used.
  • DALI Buttons
    For manual operation, DALI-2 push button couplers, like the LDALI-BM2, DALI-2 operation panels, 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.) and sunblinds via SMI (up, down, etc.), button press events can be propagated in the building network, triggering other, non-lighting related building automation functions. Support of feedback feature for pushbutton instances according to IEC 62386-332 is provided.
  • DALI Relay Modules
    Standard loads in the power grid can be controlled via DALI using DALI relay modules, like the LDALI-RM3, LDALI-RM4 and LDALI-RM8.
  • DALI Color Control
    The L-DALI allows controlling DALI luminaires with colour control functionality (DT8). Both, tunable white (Tc) and full RGB color control (RGBWAF and xycoordinate) are supported. Light color can either be changed automatically, via manual operation (e.g. buttons) or via the network.
  • 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 based on IEC 62386-202, 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).
  • DALI 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.

LonMark Interface

The L-DALI Controller maps information from the DALI network to Network Variables (NVs) to control DALI ballasts or display operating states including DALI sensor occupancy and lux level information. L-DALI Controller for LonMark Systems can be connected either to an Ethernet/IP channel (LonMark IP-852) or a TP/FT 10 channel. The provided static NV interface includes the following profiles:

  • Lamp Actuator #3040
  • Light Sensor #1010
  • Occupancy Sensor #1060
  • Constant Light Controller #3050
  • Sunblind Controller #6111
  • Open Loop Sensor (button) #1

All data points are available in a tree structure on the integrated web server to be displayed or set using a web browser.
