The Woodward 8440-2088 processes True RMS voltage and current sensing to minimize harmonic interference while executing real-time generator power management. Internal control loops calculate load distribution parameters, issuing dynamic command updates across CAN (SAE J1939) and Modbus RTU interfaces to optimize actuator loop feedback response during parallel generator operations and sudden load transitions.
Q: What alternator AC voltage sensing configurations are supported directly by the module terminals?
A: The sensing stage handles direct AC voltage inputs up to 690 Vac across 3-phase 3-wire, 3-phase 4-wire, 1-phase 2-wire, and 1-phase 3-wire generator winding topologies.
Q: How is external communication and configuration established on the easYgen-3500XT-P2 controller?
A: The unit features serial Modbus RTU for SCADA integration, CAN bus for engine ECU J1939 protocols, and a dedicated interface for parameter setup using the Woodward ToolKit software or an RP-3500XT remote panel.
Q: What are the discrete I/O capacities available for fault monitoring and output control?
A: The hardware architecture accommodates up to 23 discrete configurable alarm inputs for protection monitoring and up to 22 discrete configurable outputs for sequence control logic.
