Product Overview

The Woodward 8440-1809 is a genset control unit from the easYgen-1000 series. This model is an easYgen-1500 for non-paralleling applications. It suits mobile power and emergency stand-by systems. The unit features an LCD display and panel mount design. You can use this controller for single unit genset operations.

Technical Specifications

The Woodward 8440-1809 has an input resistance of approximately 6.7 kΩ. The linear measuring range is 1.5 x V. Load (GP) rating is 2.00 Aac at 250 Vac. Maximum power consumption is less than 0.15 W.

Key technical parameters include:

• Supply Voltage: 12-24 V DC

• Storage Temperature: -22°F to 176°F (-30°C to 80°C)

• Display Type: LCD (10 selectable languages)

• Mounting Type: Panel Mount

• Communication: CAN Open, J1939, Modbus RTU, modem

The unit provides true RMS voltage and current sensing. This applies to both generator and mains monitoring.

Alarm Classes and Operation

The 8440-1809 features six alarm classes. These are class A, class B, class C, class D, class E, and class F. Class A alarms remain as class A. Class B alarms also stay as class B. Classes C, D, E, and F all become class B alarms during operation.

The control can be set up with or without load. For load testing, the unit starts in automatic mode. If the mains fails during starting, the unit keeps running. It will continue until the mains return and settling time expires.

Control Interface and Features

The Woodward 8440-1809 offers flexible breaker configuration. You can set it for 1 or 2 breaker operation. The start-stop logic works for both diesel and gas engines. Remote-start capability allows off-site activation.

Key features include:

• LogicsManager™: Combine measured values and I/O states with boolean operators

• Programmable Timers: For complex control sequences

• Engine ECU Communication: Supports most common engine ECUs

• I/O Expansion: Connects to Woodward IKD 1 module

• Remote Annunciation: Easylite-100 panel for NFPA compliance

The unit provides complete engine and generator protection. It includes metering and mains monitoring functions.

Communication Capabilities

The 8440-1809 supports multiple communication protocols. CAN Open and J1939 connect to engine ECUs. Modbus RTU works with PLCs and external terminals. A modem connection enables remote monitoring and control.

Advanced CAN communication provides control of most engine ECUs. This includes integration with:

• Woodward IKD 1 module for I/O expansion

• Easylite-100 remote annunciation panel

• External terminals and PLC systems

The 10 selectable display languages make international use easy.

Installation Guidelines

Follow these steps for proper installation:

1. Mount the 8440-1809 in your control panel using the panel mount design.

2. Connect 12-24 V DC power to the appropriate terminals.

3. Wire the generator and mains voltage sensing inputs.

4. Connect current transformers for true RMS current sensing.

5. Set up the CAN bus for engine ECU communication if needed.

6. Configure breaker logic for 1 or 2 breaker operation.

Do not exceed the 2.00 Aac load rating at 250 Vac. Store the unit between -22°F and 176°F before installation. Test all alarm classes after configuration.

Common FAQs

Q1: What applications suit the 8440-1809 best?
A: This 8440-1809 excels in non-paralleling mobile power and emergency stand-by applications. It does not support multi-unit paralleling.

Q2: What happens to alarm classes C through F during operation?
A: Alarm classes C, D, E, and F all become class B alarms on the 8440-1809. Classes A and B remain unchanged.

Q3: Can I connect this controller to an engine ECU?
A: Yes, the 8440-1809 supports CAN Open and J1939 protocols. This allows direct communication with most engine ECUs.

Q4: Does the unit continue running if mains power fails during startup?
A: Yes, the 8440-1809 keeps running if the mains fails during starting. It stops only after mains return and settling time expire.

Q5: What languages does the LCD display support?
A: The LCD display supports 10 selectable languages. This makes the 8440-1809 suitable for international installations.
