Manual d'usuari del controlador del grup electrogen SMARTGEN HGM1791

1. Producte acabatview

The SMARTGEN HGM1791 Genset Controller is designed for single unit automation and monitoring control of gensets. It facilitates both manual and automatic start/stop operations based on remote signals. The controller continuously monitors and protects genset operation by collecting and analyzing critical data such as generation voltage, current, water temperature, and oil pressure. It provides fault indications and supports timely maintenance actions. The user interface features an LCD display with Chinese and English language options and intuitive touch-button operation. Parameters and delay values can be adjusted via the front panel or through PC software connected via a USB port.

3. Configuració

3.1 Instal·lació

The HGM1791 controller is designed for embedded installation. Ensure adequate space for mounting and access to the rear connections. The modular design with pluggable terminal blocks simplifies wiring.

3.2 Connexions de cablejat

1. Font d'alimentació: Connect the DC (8~35)V power supply to the designated terminals. Ensure correct polarity.
2. Sensors del motor: Connect engine sensors (oil pressure, water temperature, fuel level, speed sensor) to the appropriate input ports. The controller supports various sensor types, which can be user-defined.
3. Generator Connections: Connect the generator voltage, current, and frequency inputs as per the wiring diagram.
4. Sortides de control: Connect the fuel relay, start relay, and configurable output ports (e.g., common alarm, preheat, idle control) to the respective genset components.
5. Inici/aturada remots: If using remote start functionality, connect the remote start signal to the designated input.

3.3 Configuració inicial

After wiring, power on the controller. Use the front panel buttons or connect to a PC via the Type-C USB port and use the provided software to configure parameters such as sensor types, alarm thresholds, and operational delays. Refer to the detailed wiring diagram and software manual for specific parameter settings.

4. Instruccions de funcionament

The HGM1791 controller features three primary operating modes: Manual, Auto, and Stop. These modes are selected using the dedicated buttons on the front panel.

4.1 Mode d'aturada

Premeu el botó Atureu-vos button (red circle icon) to place the controller in Stop mode. In this mode, the genset will shut down if running, and will not start automatically or manually. This mode is typically used for maintenance or when the genset is not required.

4.2 Mode manual

Premeu el botó Comença button (green 'I' icon) to initiate a manual start sequence. The genset will attempt to start and run continuously until manually stopped or a fault occurs. This mode is useful for testing or specific operational requirements.

4.3 Mode automàtic

Premeu el botó Automàtic button (fan icon) to activate Auto mode. In this mode, the controller will automatically start and stop the genset based on a remote start signal or other configured conditions. The controller will also monitor the genset and initiate protective shutdowns if faults are detected. This is the typical operating mode for unattended operation.

4.4 Navegació de la pantalla

The LCD display shows various genset parameters and status information. Use the navigation buttons (if present, typically arrow keys or similar) to scroll through different screens and view detailed data such as voltage, current, frequency, engine speed, oil pressure, and temperature.

5. Manteniment

Regular maintenance ensures the longevity and reliable operation of your HGM1791 Genset Controller and the connected genset.

• Neteja: Keep the controller's front panel clean and free from dust and debris. Use a soft, dry cloth. Avoid abrasive cleaners or solvents.
• Connexions: Periodically check all wiring connections for tightness and signs of corrosion. Loose connections can lead to intermittent operation or faults.
• Actualitzacions de firmware: Comproveu el del fabricant website for any available firmware updates for the controller. Updates can improve performance or add new features.
• Condicions ambientals: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage to the electronic components.
• Comprovació de la bateria: Verify the health of the genset's starting batteries, as the controller relies on a stable power supply.
