Overview
The HGM1790N is a microprocessor-based generator set controller that provides automatic engine start/stop sequencing, AC power monitoring, and alarm protection for single diesel or gas generator units. It integrates digital measurement, programmable logic, and communication interfaces into a single panel-mounted module.
Key Features
- Microprocessor-Based Control — Advanced MCU with real-time monitoring for generator start/stop, engine protection, and AC parameter measurement
- Multi-Language LCD Display — Backlit LCD with user-selectable languages (Chinese, English, Spanish, Russian, Arabic) for international deployment
- CANbus J1939 Engine ECU Support — Direct communication with electronic engines for real-time parameter display and diagnostic trouble codes
- Flexible I/O Configuration — All digital inputs and relay outputs user-configurable for custom control logic including remote start, pre-heat, and alarm outputs
- USB & RS485 Communication — Front-panel USB for configuration and firmware updates; RS485 Modbus RTU for SCADA/BMS integration
- Comprehensive Engine Protection — Configurable alarm/shutdown for 16 engine parameters with programmable delay timers and warning pre-alarms
