Configuração e instalação

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. Preparação: 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. Remoção: Carefully disconnect all wires from the existing AVR and remove it from its mounting.
3. Montagem: Mount the DEVMO SX460 AVR securely in the designated location within the generator control panel.
4. Fiação: 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. Volume inicialtage Ajuste: 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 (e.g., 120V AC).

Observação: 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.

Princípios operacionais

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.

• Volumetage Regulamento: 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 construção.

Manutenção

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.

• Inspeção visual: Periodically inspect the AVR for any signs of physical damage, loose connections, or discoloration that might indicate overheating.
• Limpeza: 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.
• Integridade da conexão: Verify that all electrical connections to the AVR are secure and free from corrosion. Loose connections can lead to unstable voltage or component failure.

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