4. Setup and Installation

Proper installation is crucial for the safe and optimal performance of your laser power supply. Always ensure the main power is disconnected before making any connections.

Wiring Connections

Refer to the wiring diagram below for correct connections. Ensure all connections are secure and insulated.

• AC Input: Connect the 220V AC power supply to the 'AC' terminals. Ensure proper grounding to the 'FG' terminal.
• High Voltage Output: Connect the 'LASER' terminal to the high voltage input of your CO2 laser tube. This connection carries extremely high voltage and must be handled with extreme caution and proper insulation.
• Control Signals: Connect the control signals (H, L, P, G, IN 5V, P) to your laser controller board.
• Water Protection: Connect the water protection sensor to the designated terminals to ensure the laser tube is adequately cooled during operation.
• Laser Signal Input: Connect the laser signal input as per your system requirements.

Physical Installation

Mount the power supply in a well-ventilated area, ensuring adequate clearance around the cooling fan. The dimensions are 305 x 161 x 91 mm. Secure the unit using appropriate fasteners.

5. Operating Instructions

Follow these steps for safe operation of your Cloudray MYJG-150W power supply:

1. Pre-Operation Check: Before powering on, verify all wiring connections are correct and secure. Ensure the laser tube is properly installed and the water cooling system is operational and circulating water.
2. Power On: Connect the main power. The external ammeter (if connected) should display the current status.
3. Water Protection Check: Confirm the water protection signal is active (e.g., 'Water protection: ON' on the ammeter display). The laser will not fire if water protection is not engaged.
4. Laser Output Test: Use the 'TEST' button on the power supply to briefly fire the laser and confirm output. Observe the ammeter for current readings.
5. Normal Operation: Control the laser output via your laser controller board using TTL signals. Monitor the current output on the external ammeter during operation.

Ammeter Display and Adjustment

The external ammeter provides real-time feedback on the laser's operating current and status indicators. Use the trimmer potentiometer on the ammeter to fine-tune the current output as needed for your application.

6. Maintenance

Regular maintenance ensures the longevity and consistent performance of your power supply.

• Cleaning: Periodically clean the exterior of the power supply, especially the cooling fan and ventilation grilles, to prevent dust buildup and ensure proper airflow. Disconnect power before cleaning.
• Connections: Regularly inspect all wiring connections for tightness and signs of wear or corrosion.
• Environment: Ensure the operating environment is within the specified temperature and humidity ranges to prevent damage.

7. Troubleshooting

If you encounter issues with your power supply, refer to the following common troubleshooting steps:

• No Power: Check the main power connection, circuit breaker, and ensure the power supply's indicator light is on.
• No Laser Output:
  • Verify the water cooling system is running and the water protection signal is active.
  • Check the laser tube connections and ensure the tube is not damaged.
  • Confirm control signals from the laser controller are correctly sent to the power supply.
  • Use the 'TEST' button on the power supply to isolate if the issue is with the power supply or the controller/laser tube.
• Unstable Output Current: Check for loose connections, ensure stable input voltage, and verify the laser tube is not nearing its end of life.
• Overheating: Ensure the cooling fan is operating correctly and ventilation is unobstructed. Reduce ambient temperature if necessary.
