Product Overview

The Woodward 8440-2057 is a genset control unit from the easYgen-3000 series. This model is an easYgen-3100 with the Package 2 (P2) option. The unit supports single or multi-unit generator operation. You can connect up to 32 units in parallel for large power systems. The device comes in a metal housing with no display for cabinet back mounting.

Technical Specifications

The Woodward 8440-2057 has front panel dimensions of 282W x 216H x 96D mm. It operates at a measuring frequency of 50/60 Hz (40 to 85 Hz range). Maximum power consumption per path is less than 0.15 W. Resolution is 11 Bit for analog measurements.

Key technical parameters include:

• Operation Temperature: -20°C to 70°C

• CT Input Type: 1A (Class 1A current transformers)

• Communication: CANopen for external analog I/Os

• Configuration Software: ToolKit (PC-based)

• Alarm Outputs: 12 total (10 configurable)

The unit includes engine cylinder temperature protection. This feature prevents damage from overheating individual cylinders.

Features and Capabilities

The 8440-2057 supports mains parallel operations and load management. It works with both gas and diesel engines. The controller includes 3 freely configurable PID controllers for precise regulation. An extensive set of programmable setpoints provides customizable protection.

Key capabilities include:

• Start/Stop Logic: Supports gas and diesel engines

• Multi-lingual Support: Yes (via ToolKit software)

• Password Protection: Multi-level for security

• Alarm Conditions: Generator load balance, speed/frequency mismatch, mains phase shift

• Multi-unit Operation: Up to 32 gensets in parallel

The metal housing design suits cabinet back mounting. This allows integration into existing switchgear panels.

Alarm and Protection Functions

The Woodward 8440-2057 monitors many fault conditions. Twelve alarm outputs alert operators to abnormal operations. Ten of these outputs are fully configurable for your specific needs.

Protection conditions include:

• Generator load balance issues

• Engine speed or frequency mismatch

• Mains phase shift or incorrect rotation field

• Cylinder temperature exceeding limits

• Overload and fault conditions

The extensive setpoint library lets you tailor protection to your engine. This reduces nuisance trips while maintaining safety.

Installation Guidelines

Follow these steps for proper installation:

1. Mount the 8440-2057 in a cabinet with adequate ventilation.

2. Connect 1A CT inputs to your generator current transformers.

3. Wire the CANopen bus for external analog I/O expansion.

4. Connect start/stop logic to your gas or diesel engine.

5. Configure the unit using ToolKit software on a PC.

6. Set up the three PID controllers for your specific application.

The unit has no built-in display for programming. You must use a PC with ToolKit software for all configuration. Set multi-level passwords to prevent unauthorized changes.
