Configuració i instal·lació

Installation of the SX460 AVR should only be performed by a qualified technician. Ensure the generator is completely shut down and isolated from all power sources before beginning installation.

  1. Preparació: Before removing the old AVR, take a clear photograph of its wiring connections and note any jumper settings. This will serve as a crucial reference for the new installation.
  2. Eliminació: Carefully disconnect all wires from the existing AVR and remove it from its mounting.
  3. Muntatge: Mount the DEVMO SX460 AVR securely in the designated location within the generator control panel.
  4. Cablejat: Connect the wires to the corresponding terminals on the new SX460 AVR. Pay close attention to the input voltage selection jumpers (95-132V AC or 190-264V AC) and ensure they match your generator's specifications. The SX460 is a single-phase sensing unit; ensure your generator setup is compatible.
  5. Vol inicialtage Ajust: After installation and before applying full load, it may be necessary to adjust the output voltage. This can typically be done via a potentiometer on the AVR board. Aim for the exact desired output voltage (per exemple, 120 V CA).

Nota: Some older generator systems may use a three-phase sensing AVR. The SX460 is designed for single-phase sensing. Attempting to use it in a three-phase sensing configuration by connecting a third leg to terminal 6 may cause the regulator to fail. Verify your generator's requirements before installation.

Principis de funcionament

The DEVMO SX460 AVR functions by controlling the exciter field current to maintain the generator's output voltage at a preset level. It achieves this by sensing the generator's output voltage and comparing it to a stable reference. Any deviation from the reference voltage results in an adjustment to the exciter field current, thereby regulating the generator's output.

  • Voltage Reglament: Provides a regulation accuracy of ±1.0%.
  • Typical System Response:
    • AVR response: 20ms
    • Field current to 90%: 80ms
    • Machine volts to 97%: 300ms
  • Build-up Voltage: Requires a minimum of 4 Volts at the AVR terminals for voltage acumulació.

Manteniment

The DEVMO SX460 AVR is designed for reliable operation and typically requires minimal maintenance. However, periodic inspection is recommended to ensure optimal performance and longevity.

  • Inspecció visual: Periodically inspect the AVR for any signs of physical damage, loose connections, or discoloration that might indicate overheating.
  • Neteja: Ensure the AVR and its surrounding area are kept clean and free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning.
  • Integritat de la connexió: Verify that all electrical connections to the AVR are secure and free from corrosion. Loose connections can lead to unstable voltage or component failure.

Important: Always disconnect power to the generator and AVR before performing any maintenance or inspection.

Resolució de problemes

If you experience issues with your generator's voltage regulation, consider the following common troubleshooting steps:

ProblemaCausa possibleSolució
Cap voltage output or unstable voltage
  • Cablejat incorrecte o connexions soltes
  • Incorrect jumper settings for input voltage
  • Generator not building up initial voltage
  • AVR failure
  • Incompatibility with three-phase sensing systems
  • Verify all wiring against the generator's schematic and ensure connections are tight.
  • Comproveu el volum d'entradatage jumper settings (95-132V AC or 190-264V AC) on the AVR.
  • Ensure the generator provides at least 4 Volts AC to the AVR terminals for build-up.
  • If all else fails, the AVR may need replacement.
  • Confirm your generator requires single-phase sensing. If it requires three-phase sensing, this AVR is not suitable.
Volum de sortidatage massa alt o massa baix
  • Voltage adjustment potentiometer misset
  • Load issues
  • Ajusteu el voltage potentiometer on the AVR board to achieve the desired output.
  • Ensure the generator is not overloaded.
