Key Control Functions
1. Operation Control
Generator set automatic start/stop, cooling shutdown, fault emergency shutdown
Automatic grid connection synchronization: adjustable synchronization vector group, precise matching of voltage / frequency / phase, no impact closing
Active / reactive load equalization, automatic load distribution among multiple generator sets, avoiding single unit overload
Automatic power supply (grid) and generator set switching (ATS function), power supply startup upon grid failure, automatic return to grid / decoupling upon power restoration
2. Comprehensive Protection Functions
Electrical Protection: Overcurrent, overload, overvoltage / undervoltage, overfrequency / undervoltage, reverse power, phase sequence error, grounding fault
Engine Protection: High oil temperature, low oil pressure, high water temperature, overspeed, start failure, shutdown failure
Fault Alarm + Event Record, traceable tripping reasons, facilitating maintenance
3. Communication Interfaces
RS232, RS485, CAN Bus
Support Modbus protocol, can be connected to DCS/SCADA upper system for remote monitoring, remote start/stop, remote load adjustment
Multi-controller CAN networking, achieving maximum 32 generator set collaborative scheduling

 I/O Configuration Features
Isolated relay output, used for controlling start motor, fuel valve, closing and opening coil, alarm light
Multiple analog input DI for engine start/stop signals, fault contacts
Analog input for temperature, oil pressure transducer signals

Product Lifecycle and Spare Parts Status
The classic model (including 8440-2049) of easYgen-3000 has been gradually upgraded to the new generation series easYgen-3000XT (8440-208x series);
Original factory still provides firmware upgrade and technical support for the old model, and there is new inventory, disassembled second-hand, and repair refurbishment in the spare parts market;
If the equipment is old and faulty and cannot be repaired, the easYgen-3500XT (corresponding new order number) can be directly compatible and replaced, and the program can be migrated.
