3. Інформація про безпеку

Завжди дотримуйтесь наступних запобіжних заходів під час роботи з електричними компонентами та генераторами:

  • Відключити живлення: Ensure the generator is completely shut down and disconnected from any power source before attempting installation, maintenance, or repair.
  • Кваліфікований персонал: Installation and service should only be performed by qualified technicians familiar with generator electrical systems.
  • Відповідні інструменти: Використовуйте ізольовані інструменти, щоб запобігти ураженню електричним струмом.
  • Умови навколишнього середовища: Do not operate the AVR in wet or damp conditions. Ensure adequate ventilation.
  • Огляньте на наявність пошкоджень: Before installation, inspect the AVR for any visible damage. Do not install a damaged unit.

4. Монтаж

The LIHUA AVR TT91-1 is designed for direct replacement or new installation in compatible single-phase generators. Refer to your generator's specific service manual for detailed wiring diagrams and mounting instructions.

  1. Приготування: Переконайтеся, що генератор вимкнено, охолонув, а акумулятор від’єднано, щоб запобігти випадковому запуску або ураженню електричним струмом.
  2. Locate Old AVR (if replacing): Identify the existing AVR unit on your generator. Note its mounting position and wiring connections.
  3. Remove Old AVR: Carefully disconnect all wires from the old AVR. Pay attention to the color coding and connector types. Remove any mounting hardware.
  4. Mount New AVR: Secure the LIHUA AVR TT91-1 in the designated location using appropriate mounting hardware. Ensure it is firmly attached and not subject to excessive vibration.
  5. Підключіть проводку: The TT91-1 features an 8-wire harness. Connect these wires to the corresponding terminals on your generator. The harness typically includes:
    • Excitation Wires: Typically two wires (often blue or yellow) connecting to the exciter winding.
    • Sensing Wires: Two wires (often white or red) for voltage feedback from the generator output.
    • Auxiliary Power Wires: Two wires (often black or brown) providing power to the AVR.
    • Ground/Neutral Wires: One or two wires (often green or black) for grounding or neutral connection.

    Важливо: Always match the wire functions and colors according to your specific generator's wiring diagram. Incorrect wiring can cause damage to the AVR or generator.

  6. Перевірте підключення: Double-check all connections for tightness and correctness. Ensure no wires are pinched or exposed.
  7. Остаточні перевірки: Reconnect the generator battery and perform any pre-start checks as per your generator's manual.

5. Операція

Once installed, the LIHUA AVR TT91-1 operates automatically to regulate the generator's output voltage. Upon starting the generator, the AVR senses the output voltage and adjusts the excitation current to the generator's field winding, maintaining a stable voltage level under varying loads.

  • Початковий запуск: After installation, start the generator and monitor the voltage output using a voltmeter. The voltage should stabilize at the rated output (e.g., 120V or 240V, depending on your generator configuration).
  • Load Application: Gradually apply electrical loads to the generator. The AVR should maintain a consistent voltage output, compensating for changes in load.
  • томtage Adjustment (if applicable): Some AVRs may have a small voltage adjustment potentiometer. If your TT91-1 has one, make minor adjustments only if necessary and with a voltmeter connected to the output. Refer to your generator's manual for specific adjustment procedures.

6. Технічне обслуговування

The LIHUA AVR TT91-1 is designed for minimal maintenance. However, periodic checks can help ensure its longevity and reliable performance:

  • Візуальний огляд: Periodically inspect the AVR and its wiring for any signs of damage, corrosion, loose connections, or overheating.
  • Чистота: Keep the AVR free from dust, dirt, and moisture. Use a soft, dry cloth to clean the exterior. Do not use solvents or abrasive cleaners.
  • Вентиляція: Ensure that the area around the AVR is clear to allow for proper airflow and cooling.
  • Цілісність з'єднання: Check that all wire connections remain secure and free from vibration.

7. Вирішення проблем

If you experience issues with your generator's voltage output, consider the following troubleshooting steps. Always ensure the generator is safely shut down before performing any inspections or repairs.

  • Test the AVR (if possible, with specialized equipment) or replace it if suspected faulty.
  • Consult a generator technician for winding inspection.
Unstable or Fluctuating Voltage
  • Loose sensing wires.
  • Overload on the generator.
  • Engine speed fluctuations.
  • Несправний AVR.
  • Verify sensing wire connections.
  • Reduce the electrical load.
  • Check and adjust generator engine speed.
  • Consider AVR replacement.
Переволtage або Undervoltage
  • Неправильний томtage регулювання.
  • Несправний AVR.
  • If equipped, carefully adjust the voltage potentiometer while monitoring output.
  • Replace the AVR if adjustment does not resolve the issue.

If these steps do not resolve the issue, it is recommended to consult a qualified generator service technician.
