1. Pre-Installation Check: First and foremost, always ensure the excavator is powered off and the battery is disconnected. Verify that the controller’s part number matches your machine’s specific model to guarantee compatibility.
2. Secure Installation: Next, carefully connect the wiring harness, ensuring all pins are aligned properly to prevent short circuits. Securely mount the controller in its designated bracket to protect it from excessive vibration and moisture.
3. System Calibration: Afterward, power on the machine and enter the service mode to perform a system calibration. This step is essential for the EPOS (Electronic Power Optimization System) to accurately optimize engine speed and hydraulic flow.
4. Routine Maintenance: Finally, regularly inspect the electrical connectors for corrosion or loose contacts. If any abnormal error codes appear on the monitor, consult a professional technician immediately to maintain optimal performance.
