3. Istruzioni per l'uso
The HGM1791CAN controller features an intuitive LCD display and touch-button interface for easy operation.
Figure 1: Front panel of the SMARTGEN HGM1791CAN Genset Controller. It features an LCD screen displaying various parameters, along with 'Stop', 'Auto', and 'Start' buttons.
3.1. Display e navigazione
The 128x64 LCD displays real-time genset and engine parameters. Use the navigation buttons (typically arrow keys or dedicated menu buttons) to scroll through different screens and access settings.
3.2. Modalità operative
The controller supports three primary operating modes, selected via dedicated buttons on the front panel:
- Modalità di arresto: The genset is stopped and will not start automatically. This mode is typically used for maintenance or when the genset is not required.
- Modalità automatica: The genset will automatically start and stop based on a remote start signal or pre-configured conditions (e.g., low battery voltage, utility power failure).
- Modalità manuale: The genset can be manually started and stopped using the 'Start' and 'Stop' buttons on the front panel.
3.3. Parameter Monitoring
The LCD provides real-time data for comprehensive monitoring:
- Generator Parameters: Voltage (V), Frequency (Hz), Current (A), Power (kW), Load Percentage(%).
- Engine Parameters: Oil Pressure (kPa), Temperature (°C), Fuel Level (%), Battery Voltage (V), Engine Speed (RPM).
- Dati operativi: Total Running Time (H), Accumulated Start Times.
3.4. Configurazione dei parametri
Parameters can be adjusted to suit specific application requirements:
- Pannello frontale: Basic parameters and delay values can be set directly using the controller's buttons and LCD menu.
- Software per PC: For advanced configuration and comprehensive parameter adjustment, connect the controller to a PC via the Type-C USB port and use the dedicated SMARTGEN configuration software. All parameters are digitally regulated for enhanced reliability.
Nota: All user-configured parameters are stored in non-volatile memory and will not be lost in the event of a power failure.
4. Manutenzione
Regular maintenance ensures the longevity and reliable operation of your HGM1791CAN Genset Controller.
- Pulizia: Periodically clean the controller's front panel and display with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
