Core Functions

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

2. Reverse‑acting logic: fuel decreases as control signal increases; failsafe to full‑fuel position on power loss, compatible with hydraulic / electric‑hydraulic actuators.

3. Analog PID closed‑loop control with start‑up ramp, stroke limit, load rejection protection and overspeed test function.

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

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