L-DALI: CEA-709/DALI Controllers
L‑DALI Controllers are multifunctional devices combining constant light control, sunblind control, and gateway functions between LonMark and DALI (Digital Addressable Lighting Interface) 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 LonMark Systems.
Built-In or External DALI Power Supply
The LDALI‑3E101-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, these devices can handle input voltages from 85 – 240 V AC, 50/60 Hz. The LDALI‑3E102-U and LDALI‑3E104-U need an external DALI power supply to power up the DALI network. External power supplies are available for up to four DALI channels.
LonMark TP/FT10 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.
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 run-time 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 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 pushbutton coupler and IR remote controls can be integrated into the system. Their functionality can be configured individually. In addition to controlling the 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 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 projected energy consumption.
- 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.
Smooth DALI integration in LonMark Systems
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.
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 L‑DALI lineup for LonMark Systems features 1, 2, or 4 independent DALI channels. 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.
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
