8273-1011 2301E Digital Load Sharing and Speed Control

The 8273-1011 2301E is a microprocessor-based digital control module for load sharing and speed

control of generators driven by diesel or gas engines. This control module combines and is compatible with the 2301A and 2301D load sharing controls.

By increasing software flexibility, the 2301E is able to include control functions that require additional

equipment in previous versions of the 2301A and 2301D control systems. As a result, it provides an efficient,

flexible and economical solution for managing the load and speed of generators.

2301E 8273-1011

The Woodward 2301E provides load sharing and speed control of generators being driven by diesel or gaseous engines.

With the flexible configuration software incorporated in the 2301E hardware, application variations can now be

selected using an external computer (PC). Changing the application to accommodate engine speed range,

gear teeth, and selection of forward or reverse acting is a matter of software setup.

The 2301E is capable of communicating using a Modbus ® * RTU protocol, functioning as a Modbus slave device, via RS-422 drivers.

The 2301E has four operating modes:

Speed Control
Has multiple dynamics flexibility. Will work on pumps or compressors. Has capability for remote 4–20 mA speed reference through a configurable analog input.

Isochronous Load Sharing
Is compatible with most existing analog load sharing speed control systems. Now with soft load and unload capability.

Droop Base Load
Adjustable load control using discrete raise and lower contacts.

Isochronous Base Load
Provides constant load level operation against a utility bus. The load setting may be fixed, changed using discrete raise and lower inputs, or a remote 4–20 mA input.

DESCRIPTION

The Woodward 2301E microprocessor-based control functions like the 2301A load sharing and speed control and 2301D load sharing and speed control.

The control is housed in a sheet-metal chassis for ordinary and hazardous locations, and consists of a single printed circuit board.

The 2301E is configured using a computer with Control Assistant software or a Woodward ToolKit service tool.

The configuration software may be downloaded from the Woodward website (www.woodward.com). The computer

connects to the 2301E through a 9-pin connector (RS-232 port). Modbus control can be operated through the second serial port (RS-422).
