6. Упутство за употребу

Once the SX440 AVR is correctly installed and wired, its operation is largely automatic. The AVR continuously monitors the generator's output voltage and adjusts the excitation current to maintain the desired voltagе ниво.

6.1 Прво покретање

• Before starting the generator, ensure all connections to the AVR are secure and correct.
• Start the generator according to its manufacturer's instructions.
• The AVR will automatically begin to build up voltage. Monitor the generator's output voltage to ensure it stabilizes at the rated level.

6.2 Волtagе Подешавање

The SX440 AVR typically includes potentiometers for fine-tuning voltage output and stability. These adjustments should only be made by qualified personnel using appropriate measuring equipment.

• Волtagе Подешавање: Use the designated potentiometer to set the desired output voltage.
• Подешавање стабилности: Adjust the stability potentiometer to prevent voltage oscillations or hunting.
• Under-Speed Adjustment: If present, this potentiometer sets the frequency threshold at which under-speed protection activates.

Опрез: Incorrect adjustment of these settings can lead to unstable generator operation or damage to connected equipment.

7. Одржавање

The Walfront SX440 AVR is designed for long-term reliability with minimal maintenance. However, periodic inspection is recommended to ensure optimal performance and longevity.

• Визуелни преглед: Periodically inspect the AVR for any signs of physical damage, loose connections, or discoloration due to overheating.
• чистоћа: Keep the AVR free from dust, dirt, and moisture. Use a soft, dry brush or compressed air to gently clean the circuit board if necessary. Ensure power is disconnected before cleaning.
• Провере везе: Verify that all wiring connections remain tight and free from corrosion.

Напомена: Do not attempt to repair the AVR yourself. If the unit is faulty, it should be replaced by a new one or serviced by an authorized technician.
