Technical Specifications: 12/24 V DC supply, documented operating range 8–40 V DC; front-panel dimensions 282 × 216 × 96 mm; weight approximately 1.85 kg; MPU speed inputs; 4–20 mA analog inputs; RTD or thermocouple temperature inputs on configured variants; digital switch inputs; measuring range up to 1.25 times rated generator voltage; accuracy class 0.5 for voltage and current on documented variants.

Functional Features: Isochronous and droop control; automatic synchronization; dead-bus and live-bus closing; load sharing for multiple gensets; AMF functions; breaker control logic; event recorder with RTC; multilingual HMI; protection for overvoltage, undervoltage, overcurrent, reverse power, overfrequency, underfrequency and overtemperature.

Communication And Protocol: CAN J1939; RS-232 and RS-485 Modbus on documented variants; Ethernet on selected configurations; PC configuration through Woodward service/tools software.

Performance Parameters: Operating temperature -20 to +70 °C in documented controller variants; storage -30 to +80 °C; humidity 5–95 % non-condensing; front-panel protection IP66 and NEMA 4X in documented marine/industrial enclosures; paralleling support for multiple units according to system design.

Material And Structure: Industrial plastic or sealed front-panel housing depending on variant; LCD and keypad HMI; rear screw terminals; mounting flange or panel cutout for enclosure door; internal conformal-coated control board.

Working Principle: The controller measures generator voltage, current, frequency and engine speed, compares values with setpoints, adjusts fuel or governor commands, manages synchronizing relays and breaker logic, and balances load among parallel units. Protection logic issues alarms or trips when limits are exceeded.

Installation Requirements: Cut the panel opening to the 282 × 216 mm front-face outline and provide rear depth for terminals and sensors; connect MPU, CT, VT, DC supply and grounding according to the Woodward manual; use shielded cables for speed and analog circuits; separate communication from high-voltage generator wiring.

Application Scenarios: Marine generator switchboards, industrial standby plants, offshore platforms, prime-power microgrids, data-center backup systems and multi-genset parallel stations.

Usage Precautions: Verify generator CT ratio, VT ratio and nominal frequency before energizing. Validate synchronization settings with no-load tests before closed-bus operation. Do not modify protection setpoints without authorized engineering values. Inspect marine sealing and grounding regularly in humid or salty environments.
