Description
1. Product Overview
Part Number: 8446-1068
Manufacturer: WoodwardCompatible System: Dedicated remote human-machine terminal matching easYgen-3000XT series generator set main controller, an EOL discontinued critical spare part for unit remote monitoring and operation; its equivalent model is 8446-1061.Product Definition: RP-3000XT Touch Screen Remote Control & Annunciation Panel. It serves as a remote operation terminal for the easYgen-3000XT control system. It reads unit operating data, start/stop status, fault alarms, grid paralleling parameters and protection event records via fieldbus communication. It supports remote unit start/stop, setpoint modification, historical fault query and alarm reset, with integrated audible and visual alarm functions. It can be installed in central control rooms, duty rooms or local cabinets away from the unit to realize centralized multi-point monitoring and operation, acting as the core HMI hardware for parallel grid connection and automatic transfer switch power supply systems of diesel and gas generator sets.2. Hardware Structure & Six Functional Units
2.1 7-inch Touch Display & HMI Unit
Equipped with a 7-inch industrial color LCD and resistive touch panel adaptable to dusty and oily industrial environments. Multi-language switching between Chinese and English is supported, with hierarchical menus for overview, parameter configuration, fault history, synchronization and protection settings. It displays voltage, current, frequency, power, coolant temperature, oil pressure and breaker status, and allows touch-based remote unit control including emergency stop and breaker switching.
2.2 RS485 Fieldbus Communication Unit
Adopts MODBUS-RTU protocol RS485 interface with CRC data check and disconnection self-diagnosis. Multiple RP-3000XT panels can be connected to one main controller on a single bus, with a maximum transmission distance of 1200 meters via shielded twisted pair cable for long-distance central control wiring.
2.3 Fault Audible-Visual Alarm & Event Storage Unit
Built-in buzzer and status LED trigger flashing light and acoustic alarm upon faults such as overvoltage, underfrequency, overload and overspeed. Non-volatile flash memory stores no less than 200 timestamped fault records with data retention after power loss, supporting single alarm reset or global alarm clearing.
2.4 Embedded Wide-Voltage Power Supply Unit
Accepts DC 12~30V input with recommended 24VDC industrial power supply. Integrated EMI filter, reverse polarity protection, overcurrent fuse and surge clamping prevent system crash or black screen caused by voltage fluctuation and power surge. Isolated power design eliminates crosstalk interference between power and communication circuits.
2.5 Embedded Firmware & Logic Processing Unit
32-bit industrial MCU runs Woodward original firmware fully matched with easYgen-3000XT. Two-level password permission management restricts critical parameter modification to authorized administrators only to avoid misoperation risks. Automatic bus address detection after power-on simplifies system commissioning.
2.6 Cabinet Embedded Installation & Industrial Protection Unit
Standard flush mounting design with back clip fixation without extra screws. Front panel IP65 rated against water splash and dust; full conformal PCB coating provides moisture, corrosion and salt fog resistance. Fanless passive cooling ensures stable operation in harsh environments such as chemical plants and offshore platforms.

4. Product Advantages
- Factory-tailored firmware matches easYgen-3000XT natively without protocol converters or gateways, minimizing intermediate fault points and simplifying commissioning.
- Multi-terminal bus topology enables synchronous monitoring and operation from multiple locations such as control rooms and on-site cabinets, ideal for distributed backup power systems.
- Password permission lock prevents unauthorized modification of grid paralleling and protection setpoints to avoid accidental system trips and equipment damage.
- Independent fault log storage retains historical events after main unit power failure, greatly accelerating root-cause troubleshooting of power supply outages.
- IP65 front panel eliminates the need for extra protective covers for field cabinet installation, adapting to outdoor and dusty industrial sites.
- Fanless maintenance-free design with conformal coating achieves long service life matching generator overhaul cycles with zero routine upkeep.
5. Application Scenarios
Remote monitoring and ATS control for emergency backup generators in hospitals and data centers; dual-site supervision of gas generation units at oil and gas well sites and gas gathering stations; centralized grid paralleling and load regulation for captive power plants in steel and chemical facilities; direct drop-in replacement for aging RP-3000XT panels, HMI system upgrade and preventive spare part stocking for legacy easYgen-3000XT control systems.
