3. Продукт бүтүп калдыview

The LMRC-212 is a digital 2-relay room controller that serves as a foundational component of a Watt Stopper Digital Lighting Management (DLM) system. It features two relays for switching loads and two 0-10 volt outputs for dimmable loads, such as electronic ballasts. The device facilitates integration with various lighting control components via RJ-45 connectivity.

Негизги өзгөчөлүктөрү:

• Digital 2-Relay Room Controller
• RJ-45 Connectivity for DLM network integration
• On/Off/0-10 Volt Dimming capabilities
• Supports 120/277V, 20 Amps
• Provides 24VDC, 250 mA output for DLM devices

5. Орнотуу жана зымдар

Before beginning installation, ensure that power to the circuit is disconnected at the main breaker. The LMRC-212 is designed for wall mounting and integrates into a Digital Lighting Management (DLM) network.

Зымдарды туташтыруу:

1. Кубат киргизүү: Connect the 120/277V AC power supply to the designated terminals.
2. Туташууларды жүктөө: Connect lighting loads to Load A and Load B terminals. The LMRC-212 supports two independent relays.
3. 0-10V Dimming Outputs: Connect 0-10V dimmable ballasts or LED drivers to the respective 0-10V Dimming Output terminals (Violet + and Grey - for each load).
4. DLM Network Connection: Connect the LMRC-212 to the DLM Local Network using an RJ-45 cable. Маанилүү: Connect only to a DLM Local Network, not to Ethernet.

Configuration Button:

The device includes a configuration button (labeled "Config") for initial setup and pairing with other DLM devices. Refer to the DLM system guide for detailed configuration procedures.

6. Операция

Once installed and configured within a DLM system, the LMRC-212 controls connected lighting loads based on inputs from DLM occupancy sensors, daylight sensors, and wall switches.

Manual Control (via connected DLM switches):

• Күйгүзүү/өчүрүү: A quick press and release of a connected DLM switch button will toggle the associated load On or Off.
• алсыздатуу: Press and hold a connected DLM switch button to adjust the dimming level of the associated 0-10V dimmable load. Release the button when the desired light level is reached.

The specific behavior and grouping of loads are determined during the DLM system configuration process.

7. Техникалык тейлөө

The LMRC-212 is designed for long-term, reliable operation with minimal maintenance. Periodically inspect the device and its connections to ensure proper functioning.

• Тазалоо: Тазалоодон мурун электр кубатынан ажыратыңыз. Сыртын жумшак, кургак чүпүрөк менен сүртүңүз. Абразивдүү тазалоочу каражаттарды же эриткичтерди колдонбоңуз.
• Текшерүү: Annually inspect wiring connections for tightness and signs of wear or damage.
• Микропрограмма: For firmware updates or advanced diagnostics, consult a qualified Legrand Watt Stopper technician or refer to the latest DLM system documentation.

8. Кыйынчылыктарды

If the LMRC-212 or connected lighting loads are not functioning as expected, perform the following basic troubleshooting steps:

• Кубат жок:
  • Check the circuit breaker or fuse supplying power to the controller.
  • Verify all power connections to the LMRC-212 are secure.
• Loads Not Responding:
  • Ensure the DLM network cable (RJ-45) is securely connected to the LMRC-212 and other DLM devices.
  • Verify that the connected DLM switches or sensors are properly configured and communicating with the LMRC-212.
  • Check the wiring to the lighting loads (Load A, Load B) and 0-10V dimming outputs.
  • Confirm that the loads themselves are functional.
• Караңгылык маселелери:
  • Ensure that the connected fixtures are indeed 0-10V dimmable and compatible with the LMRC-212.
  • Check the polarity of the 0-10V dimming wires (Violet + and Grey -).
