Core Functions

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

2. Reverse‑acting control logic: fuel increases as control output decreases; power‑loss fail‑safe to full‑fuel position, compatible with mechanical backup governors.

3. PID closed‑loop control with startup ramp, actuator stroke limit, load rejection protection and overspeed test.

4. Supports 4‑20 mA analog remote setpoint for speed/load adjustment, compatible with DCS/PLC systems.

5. RS‑485 Modbus‑RTU communication for real‑time monitoring and parameter configuration.
