Need help?Do you have a question about the Bruce BR3000-330-2CL and is the answer not in the manual?
The BR3000-330-2CL, -3CL, -2EN Mood Lighting System (MLS) is a sophisticated lighting system designed for Airbus A330 aircraft, featuring LED-based, multi-color capable luminaires. It is a component maintenance manual (CMM) and illustrated parts list (IPL) for the BR3000-330-2CL, -3CL, and -2EN versions of the Mood Lighting System, manufactured by Bruce Aerospace. The BR3000 MLS is designed for use in the following aircraft types: Airbus A330 -200 Classic Cabin (BR3000-330-2CL), Airbus A330 -300 Classic Cabin (BR3000-330-3CL), and Airbus A330 -200 Enhanced Cabin (BR3000-330-2EN).
The BR3000 MLS provides a comprehensive mood lighting solution, offering multi-color light output utilizing a mixed array of red, blue, green, and white LED emitters (RGBW). The system is designed to create various lighting scenarios within the aircraft cabin, transitioning smoothly between different colors and intensities. It supports both Business Class (BC) and Economy Class (EC) zones on the A330 aircraft, with separate MLS systems for each zone. Each MLS system comprises a Mood Lighting Control Panel (MLCP) and multiple Lighting Control Modules (LCMs). The MLCP serves as the heart of the MLS system, storing scenario execution data and controlling the lighting intensity and timing. It communicates with the LCM units via a Controller Area Network (CAN) serial protocol. The LCMs are LED-based luminaires that receive commands from the MLCP to produce the desired lighting effects. The system also includes CAN Bus Terminators to ensure proper network communication.
The system operates on 115 Vac, 400 Hz input power for the LCM units, and 28 Vdc power for the MLCP. The MLCP is a 32-bit microcontroller-based device with internal EEPROM memory for storing scenario data sets. It features a capacitive backup circuit to maintain power during momentary interruptions. The MLCP includes a USB port for real-time control and scenario uploads, as well as an RS-485 serial controller and two CAN bus controllers. The LCM units come in two main sizes: 20-inch and 35-inch. The 20-inch LCMs are available in Hat-Rack (BC1-0229-001), Sidewall (BC1-0229-002), and Ceiling (BC1-0229-003) configurations. The 35-inch LCMs are also available in Hat-Rack (BC1-0230-001), Sidewall (BC1-0230-002), and Ceiling (BC1-0230-003) configurations. Each LCM unit contains a single, master microcontroller device to receive scenario command data from the MLCP unit via CAN serial protocol. The LCMs incorporate a 50 Vdc flyback circuit for power conversion and LED driver boards for controlling the RGBW LEDs. The LED driver boards feature analog sensors and photo sensors to ensure accurate color and temperature control. The CAN Bus Terminator (BC1-0216-001) is a 120-ohm device that terminates the CAN bus trunks, preventing unwanted reflections or distortion of data signals.
The BR3000 MLS offers a user-friendly interface through the MLCP, which features various control buttons for different lighting scenarios such as DAY, NIGHT, BOARD/DSMBARK, TAXI/TAKEOFF/LAND, TEST, BAR, MEAL, CRUISE, and SLEEP. It also includes a "WHITE LIGHT SELECTION" control with LOW, MEDIUM, and HIGH settings. The MLCP allows for the selection of ten predefined scenarios, which can be executed with a single button press. The system supports both default power-up conditions (High Default White) and user-defined scenarios. The USB port on the MLCP allows for easy upload of new scenarios and real-time control via a connected laptop. The system is designed to seamlessly integrate with the aircraft's existing attendant control panels, allowing for manual control of cabin wash lights and other lighting functions. The MLCP also features LED indicators for visual feedback on button presses and scenario status.
Maintenance of the BR3000 MLS primarily involves daily checks, scheduled maintenance, and troubleshooting procedures. Daily checks include verifying that all LCM units are illuminated and that no individual LED boards are malfunctioning. In case of a malfunctioning segment, the entire LCM unit should be turned off. Scheduled maintenance tasks are recommended to ensure the system's optimal performance and are incorporated into the operator's airplane maintenance program. The system is designed with Line Replaceable Units (LRUs) to facilitate easy replacement of faulty components. Troubleshooting procedures include operational level flowcharts to diagnose issues such as power interruptions, brown-out conditions, and communication failures. Specific tests are outlined for LED checks and data cable integrity. For instance, if a data cable issue is suspected, resistance readings on the MLCP connector pins can help identify open or shorted cables. The manual provides detailed instructions for LRU removal and replacement for the MLCP, 20-inch LCM units (Hat-Rack, Sidewall, Ceiling), 35-inch LCM units (Hat-Rack, Sidewall, Ceiling), and CAN Bus Terminator. Recommended cleaning materials and procedures are provided for the BR3000 MLS LRUs, emphasizing the use of lint-free cloths and approved solvents to prevent damage. Inspection guidelines are also provided to identify physical damage, discoloration, loose hardware, and other issues that may require repair or replacement. The manual also includes information on bench testing procedures for LRU units, including required test equipment and detailed steps for input current measurement, on/off control, and CAN communication. Storage instructions for LRU components are also provided, specifying environmental conditions to prevent corrosion and damage.
