Key Components:

• Config Button: Used for device configuration and network setup.
• Load A Button: Controls the connected Load A.
• DLM Network Ports: Two RJ45 ports for connection to a DLM Local Network. (Note: Not for standard Ethernet connections.)
• 0-10V Dimming Terminals (+A-): Green terminal block for Class 2 wiring of 0-10V dimming output.
• Power Input: Accepts 120/277 VAC, 50/60Hz.

4. Installation

Before beginning installation, ensure all power to the circuit is disconnected at the main breaker.

4.1 Wiring the Power and Load

1. Connect the incoming 120/277 VAC power supply to the appropriate terminals on the LMRC-111 as per the wiring diagram provided with the product packaging.
2. Connect the load (e.g., lighting fixtures) to the relay output terminals. The device supports a maximum load of 10A for Ballast, E-Ballast, and Incandescent loads at 120VAC/277VAC.

4.2 0-10V Dimming Output Wiring

1. Locate the green terminal block labeled '+A-' for 0-10V dimming.
2. Connect the 0-10V dimming control wires from the dimmable ballast or LED driver to these terminals. Ensure correct polarity (+ to + and - to -).
3. This connection requires Class 2 wiring only.

4.3 DLM Network Connection

1. Connect the LMRC-111 to other DLM devices using standard RJ45 patch cables.
2. Ensure connections are made to a DLM Local Network only. Do not connect to a standard Ethernet network.

5. Operating Instructions

5.1 Basic Operation

• Load A Button: Pressing this button will toggle the connected Load A on or off.
• 0-10V Dimming: The device provides a 0-10VDC dimming output to control compatible lighting fixtures. Dimming levels are typically controlled by other DLM devices or sensors within the network.

5.2 Configuration

The 'Config' button is used for advanced setup and integration into a DLM network. Refer to the comprehensive DLM system installation guide for detailed configuration procedures, including addressing, grouping, and sensor integration.

6. Maintenance

The LMRC-111 is designed for maintenance-free operation. Periodically inspect the device and its connections for any signs of damage or wear. Clean the exterior with a soft, dry cloth if necessary. Do not use abrasive cleaners or solvents.

7. Troubleshooting

• No Power: Check the circuit breaker and all power connections. Ensure the input voltage is within the specified range.
• Load Not Responding: Verify that the load is correctly wired to the relay output. Check the load itself for functionality. Ensure the DLM network is properly configured.
• Dimming Not Working: Confirm that the 0-10V dimming wires are correctly connected with proper polarity. Ensure the connected ballast/driver is 0-10V dimmable and functioning correctly.
• Network Communication Issues: Check RJ45 cable connections. Ensure the device is connected to a DLM Local Network, not an Ethernet network. Consult the DLM system guide for network diagnostics.
