2. Nastavení a instalace
Proper installation is crucial for the reliable operation of the HGM1790N controller. This section outlines the physical mounting and electrical connections.
2.1 Fyzická instalace
The HGM1790N controller is designed for front panel mounting. Ensure the panel cutout dimensions are accurate for a secure fit. The case dimensions are 95mm x 86mm x 46.5mm, and the panel cutout is 78mm x 66mm. When installing, ensure the waterproof rubber gasket is used between the controller and the panel fascia to achieve IP55 protection level.

2.2 Elektrické připojení
All electrical connections should be made with the power supply disconnected. Refer to the wiring diagram for detailed connections. The controller operates on a DC (8~35)V power supply, compatible with 12V or 24V starter batteries. Ensure correct polarity when connecting the battery (B+ and B- terminals).

Input, Remote Start Input, Crank Output, Fuel Output, Em. Stop Input, B+, B-, GENS (L, N), Load (I*, I), Idle Output, Stop Output, and Aux. Output.

Figure 2.3: Detailed wiring schematic for the HGM1790N controller, illustrating connections for power, load, remote start, auxiliary inputs, engine sensors (oil pressure, temperature), and magnetic pickup. Note: Start and fuel output ports should use large capacity relays. When sensor port configured as "high digital input is active", hanging in air means high electrical level is selected; cannot be connected to power supply positive.
Důležité poznámky k zapojení:
- Start and Fuel Output: These ports require large capacity relays for proper operation.
- Konfigurace senzoru: If a sensor port is configured for "high digital input is active", leaving it unconnected (hanging in air) will result in a high electrical level. Do not connect such a port directly to the positive power supply.
- Kompatibilita snímačů: The controller is compatible with multiple temperature, pressure, and fuel level sensors. These can be user-defined and used directly. Temperature and pressure sensors can be used in parallel with an annunciator, providing analog quantity and increasing protection level.
3. Návod k obsluze
The HGM1790N controller offers three primary operating modes: Manual, Auto, and Stop. Operation is managed via the touch-buttons on the front panel.
3.1 Ovládací tlačítka
- Tlačítko Stop (červené): Used to stop the genset and enter Stop mode.
- Auto Button (White/Grey with swirl icon): Used to select Auto mode, enabling remote start/stop functionality.
- Tlačítko Start (zelené): Used to manually start the genset.
3.2 Provozní režimy
Režim zastavení: In this mode, the genset is stopped. Press the Stop button to enter this mode. The controller will cease all operations and clear any active alarms.
Manuální režim: To manually start the genset, press the Start button. The controller will initiate the starting sequence. To stop, press the Stop button.
Automatický režim: Press the Auto button to enable automatic operation. In Auto mode, the controller will respond to remote start/stop signals. The genset will start automatically upon receiving a valid remote start signal and stop when the signal is removed or a fault occurs.
3.3 Parameter Monitoring and Display
The graphical LCD displays various genset parameters and fault conditions. Parameters measured and displayed include:
- Generator Voltage (V)
- Generator Frequency (Hz)
- Generator Power (kW)
- Generator Current (A)
- Načíst procentotage (%)
- Tlak oleje (kPa)
- Teplota (° C / ° F)
- Hladina paliva (%)
- Total Running Time (H, max. 199999 hours)
- Baterie Voltage (V)
- Otáčky motoru (RPM)

Parameter thresholds and delay values can be adjusted via the front panel or through a USB port connected to PC software.
4. Údržba
Regular maintenance ensures the longevity and optimal performance of your HGM1790N controller. While the unit is designed for durability, periodic checks are recommended.
- Čištění: Keep the front panel clean and free of dust and debris. Use a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Spojení: Periodically check all wiring connections for tightness and signs of corrosion. Loose connections can lead to intermittent operation or faults.
- Podmínky prostředí: Zajistěte, aby provozní prostředí zůstalo v rámci specifikovaného rozsahu teploty a vlhkosti, aby nedošlo k poškození vnitřních součástí.
- Aktualizace firmwaru: Zkontrolujte výrobce website for any available firmware updates that may improve performance or add features. Updates are typically performed via the USB port with PC software.
