Core Functions

1. Dual control modes: isochronous mode for standalone genset constant‑speed operation; droop mode for multi‑unit parallel load sharing

2. Precise speed/load regulation, supporting critical speed avoidance, valve limit and startup protection

3. Integrated overspeed protection, real‑time monitoring, self‑diagnosis and multi‑channel alarm output

4. 4‑20 mA analog remote setpoint input, compatible with upper‑level DCS/PLC system linkage

5. Synchronization, deceleration control, fuel limit and other auxiliary control functions

6. Parameter configuration, online tuning and real‑time monitoring via dedicated Woodward software
