Woodward 8440-1923 is a legacy easYgen-3200 genset controller documented in Woodward easYgen-3000 manuals for software version 1.15xx. It uses the earlier front-panel greyscale display generation for generator and mains-parallel applications.
Woodward 8440-1923 supports stand-by, automatic mains-failure, peak-shaving, import/export, cogeneration, island-parallel and multiple-unit operation. The easYgen-3200 platform can coordinate generator and mains circuit breakers and networked load sharing.
The easYgen-3000 architecture provides configurable generator and mains measurements, protection, alarms, analog and discrete I/O, CAN interfaces and RS-232/RS-485 communication. Application settings must match the installed CTs, voltage sensing, breakers and engine ECU.
Woodward documents 8440-2050 as the later color-display part-number transition from 8440-1923. Although settings can share common parameters, firmware, display generation, terminal mapping and newly introduced parameters must be reviewed before migration.

Woodward 8440-1923 is a legacy easYgen-3200 front-panel genset controller with the earlier greyscale display, designed for generator, mains-parallel and multiple-unit power-management applications.
Woodward 8440-1923 supports stand-by, AMF, peak-shaving, import/export, cogeneration, island-parallel and mains-parallel operation when its breaker logic, sensing and application configuration are correctly engineered.
Woodward easYgen-3000 documentation specifies a 12/24 Vdc nominal supply with an 8–40 Vdc operating range. Verify the Woodward 8440-1923 nameplate, polarity and protection before connection.
Woodward 8440-1923 provides configurable generator and mains breaker control, synchronization, open or closed transition and breaker monitoring. Confirm feedback contacts, coil voltages, interlocks and fail-safe states.
Woodward 8440-1923 uses the easYgen-3000 communication architecture with CAN, RS-232 and RS-485 interfaces and documented CANopen, J1939 and Modbus RTU functions, subject to configuration.
Install Woodward 8440-1923 only after checking panel cutout, supply, grounding, CT polarity, voltage sensing, breaker circuits, engine interfaces, CAN termination, serial wiring and approved terminal diagrams.
Woodward identifies 8440-2050 as the color-display successor to Woodward 8440-1923. Review hardware revision, software, terminal mapping and every added or removed parameter before transferring settings.
Commission Woodward 8440-1923 by proving voltage and current sensing, phase rotation, breaker synchronization, protection, alarms, load sharing, engine communication, operating modes and emergency shutdown behavior.
Provide the complete Woodward 8440-1923 part number, revision, serial number, firmware, saved settings, CT secondary rating, system voltage, breaker arrangement, network design, approvals, quantity and destination.
Send the complete model, part number, revision, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
