4. Setup

4.1. Mounting

The MX3G-32MRT module is designed for DIN rail mounting. Securely attach the module to a standard DIN rail in a control cabinet, ensuring adequate ventilation space around the unit.

4.2. Wiring

Follow these general guidelines for wiring the PLC module:

• Power Supply: Connect a stable DC power supply to the designated power input terminals. Observe correct polarity.
• Digital Inputs: Connect your digital input devices (e.g., push buttons, limit switches) to the digital input terminals. Refer to the module's specific wiring diagram for input type (sink/source) compatibility.
• Transistor Sink Outputs: Connect your output devices (e.g., relays, indicator lights) to the transistor sink output terminals. Ensure the load current does not exceed the specified maximum for each output.
• Analog Inputs: Connect analog sensors (e.g., temperature, pressure) to the analog input terminals. Ensure proper signal type and range matching.
• Grounding: Connect the module's ground terminal to a reliable earth ground.

4.3. Initial Connection

Connect the PLC module to a computer using a compatible programming cable via the designated communication port. Install the necessary drivers and programming software on your computer.

5. Operating Instructions

5.1. Powering On

After completing all wiring and connections, apply power to the PLC module. The power indicator LED should illuminate, indicating successful power-up.

5.2. Programming

Use the compatible programming software to develop and download your control logic program to the PLC. The software provides an environment for creating ladder logic, function block diagrams, or other programming languages supported by the module.

5.3. Run Mode

Once the program is downloaded, switch the PLC to RUN mode (either via software or a physical switch if available). The PLC will then execute the loaded program, controlling the connected inputs and outputs according to the logic.

5.4. Monitoring

The programming software allows for real-time monitoring of input/output status, internal registers, and program execution. This is crucial for debugging and verifying system operation.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of your PLC module:

• Cleaning: Periodically clean the module and its surroundings to prevent dust accumulation, which can lead to overheating or short circuits. Use a soft, dry cloth. Do not use solvents.
• Environmental Control: Ensure the operating environment remains within the specified temperature and humidity ranges.
• Connection Checks: Periodically inspect all wiring connections for tightness and signs of corrosion or damage.
• Firmware Updates: Check the Coolmay official website for any available firmware updates that may improve performance or add new features. Follow the provided instructions carefully for any update procedures.
