The Woodward easYgen-1500 Series is a second-generation genset controller designed for single-unit operation, offering exceptional flexibility and a user-friendly experience. Model 8440-1809 is a high-performance controller in this series, featuring a large graphical display suitable for various applications ranging from simple measurement conversion to complex automatic mains failure (AMF) and standby power systems.
This controller integrates several innovative technologies, including FlexApp™, DynamicsLCD™, FlexIn™, FlexCAN™, and LogicsManager™, allowing users to freely configure the controller’s functions, I/O, and logic according to specific application needs. Whether used for engine control, single-breaker control, or dual-breaker (GCB/MCB) AMF applications, the easYgen-1500 provides reliable and accurate genset protection and control.
The 8440-1809 employs true RMS measurement technology, supports wide-voltage FlexRange™ inputs, and incorporates comprehensive generator, engine, and mains protection. Its compact flush-mounting design, multi-language interface, event recorder, and various communication interfaces make it an ideal choice for industrial power generation, marine applications, standby power, and island operation.

FlexApp™ Application Modes
The easYgen-1500 Series supports four configuration modes via FlexApp™ technology. Users can select the appropriate mode without hardware changes.
Mode Code | Description | Breaker Control | Typical Application |
0 | Measuring transducer / engine control | No CB control | Measurement and display only, engine start/stop |
1a (1c) | Single breaker control (GCB open only / open-close) | GCB open/close | Generator isolated operation, no mains interaction |
2c | Dual breaker control (GCB and MCB open/close) | GCB and MCB open/close | AMF (auto mains failure), standby power, open transition |
Note: Model 8440-1809 supports full dual-breaker AMF applications with mains voltage and current measurement.
Protection Functions (ANSI Codes)
ANSI Code | Protection Function | Description |
59 / 27 | Overvoltage / Undervoltage | Configurable for generator and mains sides |
81O / 81U | Overfrequency / Underfrequency | Adjustable thresholds and delays |
32 / 32R | Overload / Reverse (reduced) power | Protects generator from motoring |
46 | Unbalanced load | Detects three-phase current imbalance |
50 / 51 | Definite time overcurrent | Phase overcurrent protection |
IEC255 | Inverse time overcurrent | Complies with IEC 255 characteristic curves |
Ground Fault | Calculated + measured ground fault | Configurable as alarm or shutdown |
Additional protections include battery voltage monitoring, overspeed, engine pre-glow or purge control, etc.
I/O Configuration Overview (by Application Mode)
I/O Type | Mode 0 | Mode 1a/1c | Mode 2c |
Speed Input (magnetic/switching) | 1 | 1 | 1 |
Configurable Discrete Alarm Inputs | 8 | 8 | 8 |
