5. 사용 설명서
Once installed, the SX460 AVR automatically regulates the generator's output voltage. Minimal adjustment may be required for optimal performance.
5.1. Initial Start-up and Adjustment
- After ensuring all connections are correct and secure, start the generator.
- Monitor the generator's output voltage using a suitable voltmeter.
- 볼륨이tage is not at the desired level, locate the voltage adjustment potentiometer on the AVR board.
- Carefully turn the potentiometer with a non-conductive tool to achieve the required output voltage. Make small adjustments and allow the system to stabilize between turns.
- The SX460 is designed for a pressure regulation accuracy of less than ±1%.
6. 유지관리
