Figure 4.1: Typical Application Wiring Diagram
This diagram illustrates the typical wiring connections for the HGM9520 controller in a generator application. It shows connections for load, mains, generator, auxiliary outputs, inputs, fuel, oil pressure, engine temperature, CANBUS, and RS485. Note the fuse requirements for F1 (min. 2A; max. 20A) and F2 (min. 32A).

Magetsi: Connect the DC power supply to the designated terminals. Observe polarity.
Generator Inputs: Batanidza voltage and current transformers (CTs) for generator monitoring.
Mains Inputs: Batanidza voltage transformers for mains monitoring.
Engine Sensors: Connect sensors for oil pressure, engine temperature, fuel level, etc.
Communication Ports: Connect RS485 for remote communication and USB for PC configuration.
Fuse: Ensure appropriate fuses are installed for F1 (min. 2A; max. 20A) and F2 (min. 32A) as indicated in the wiring diagram.

5. Operating Instructions

5.1 Powering On and Initial Display

Once correctly wired and powered, the controller will perform a self-test and display the main operating screen. The 4.3-inch TFT-LCD will show real-time generator and mains parameters.

5.2 Navigation and Parameter Configuration

Use the navigation buttons (Up, Down, Left, Right, Enter, Esc) to browse menus and adjust settings.
Most common parameters can be adjusted directly from the front panel.
For advanced configuration, connect the controller to a PC via USB or RS485 and use the SMARTGEN configuration software.

5.3 Maitiro Okushandisa

The HGM9520 supports various operating modes, selectable via the front panel buttons:
