Woodward 8440-2056 easYgen-3100 Genset Controller

Woodward 8440-2056 Technical Specifications and Features

Product Introduction

The Woodward 8440-2056 belongs to the easYgen-3000 series and comes in a metal housing without a built-in display. You will use this controller for single or multi-unit genset applications. Its peer-to-peer paralleling functionality allows connection of up to 32 units. Moreover, the 8440-2056 supports both diesel and gas engine start/stop logic. For configuration and monitoring, you need ToolKit software on a PC.

Key Technical Specifications

Power Supply: 12/24V DC with a wide operating range of 8 to 40V DC.
Measuring Frequency: 50/60Hz, covering 40 to 85 Hz.
Primary Setting Range: 50 to 650,000 Vac.
Current Setting Range: 1 to 32,000 A.
CT Input Type: 5A current transformer inputs (distinguishing this model from the 1A version).

Protection and Relay Features

Relay Outputs: Isolated relay outputs provide safe switching for external devices.
Alarm Capability: The unit triggers alarms based on programmable setpoints.
For instance, you can monitor overcurrent, underfrequency, or phase rotation issues. Additionally, the 8440-2056 offers extensive protection for generator and mains conditions. Therefore, your equipment stays safe under abnormal operations.

Multi-Lingual Interface and Event Recording

Supported Languages: English, German, Spanish, French, Italian, Portuguese, Japanese, Chinese, Russian, Turkish, Polish, Slovakian, Finnish, and Swedish (14 languages total).
Event Recorder: The built-in real-time clock records up to 300 events.
Counters: You get dedicated counters for operating hours, engine starts, and maintenance intervals.
Specifically, the Woodward 8440-2056 helps you track service needs without extra hardware.

Operating Modes and Breaker Control

This controller provides four operating modes: Automatic, Manual, Stop, and Test (Load or No Load). For manual breaker control, you configure the voltage and frequency settings accordingly. Furthermore, the unit supports open or closed transition switching. Besides that, load-dependent start/stop features optimize fuel efficiency in multi-unit setups.

Mechanical and Environmental Parameters

Housing Material: Metal housing with no display (intended for cabinet back mounting).
Front Panel Dimensions: 282W x 216H x 96D mm (same as other 3100 models).
Operation Temperature: -20°C to 70°C, suitable for harsh industrial rooms.
Storage Temperature: -30°C to 80°C.

Communication and Software Requirements

The 8440-2056 does not have a local HMI panel. Instead, you connect a PC running Woodward ToolKit software (manual 37258P). This software supports multi-level password protection and multi-lingual menus. Meanwhile, the peer-to-peer paralleling feature allows direct communication between multiple genset controllers without a central master.

Installation Guidelines

First, mount the Woodward 8440-2056 inside a control cabinet using the four corner screws. Next, connect the 12/24V DC power supply to the dedicated terminals (8-40V range). Then, wire your 5A current transformers to the CT inputs. For generator voltage sensing, use the primary setting range of 50 to 650,000 Vac. Finally, connect the isolated relay outputs to your breaker trip and close coils. Remember to configure all parameters through ToolKit before commissioning.

Frequently Asked Questions (FAQ)

1. Can the Woodward 8440-2056 work with 1A current transformers?
No, this specific model requires 5A CT inputs. For 1A CTs, please choose model 8440-2057 instead.

2. Do I need a separate HMI to operate the 8440-2056?
No, but you must use ToolKit software on a Windows PC for programming. The unit has no built-in display.

3. How many gensets can I parallel using this controller?
You can connect up to 32 units using the peer-to-peer paralleling functionality with automatic sequencing.

4. What happens during a power supply voltage drop?
The controller operates reliably down to 8V DC. Below that, it will shut down safely without damaging internal circuits.

5. Does the 8440-2056 support load-dependent start/stop?
Yes, it includes load management features such as load-dependent start/stop and mains parallel operation with open or closed transition.
