Woodward 2300E – Ordinary Locations 8273-1017
The 2300E is a digital control that can be programmed with applicable application software. This control is
housed in a sheet metal chassis and consists of a single printed circuit board. This control is designed to
perform the speed and load control functions for a small engine, steam turbine, or gas turbine. The 2300E
has no application software in it when shipped from Woodward, which allows it to be configured and
modified to meet site-specific requirements. It utilizes the Woodward GAP 3.X software to create an
application specific application software that can be downloaded to the 2300E.
The 2300E has the following Woodward part numbers:
8273-1017
2300E Load Sharing and Speed Control, 24 Vdc input, Ordinary
Locations
8273-1018
2300E Load Sharing and Speed Control, 24 Vdc input, Hazardous
Locations
The control is housed in a sheet-metal chassis and consists of a single printed circuit board. The 2300E is
set up and configured through an external computer connected at the 9-pin connector (RS-232 Port) at
the front of the control. The configuration software, Control Assistant, can be downloaded from our
website at www.woodward.com.
The 2300E has two serial communication ports, allowing it to easily interface with a Human Machine
Interface (HMI), PLC, or plant DCS. These configuration and dynamic settings are set, changed, tuned,
and saved via a laptop computer and Woodward’s user-friendly Control Assistant software program. This
program allows users to set and adjust all application-based parameters, plus upload and download
configurations to and from the control. Woodward’s Toolkit software is also capable of communicating to
the 2300E
The 2300E Control Hardware includes:
1 Load Sensor
• 1 Actuator Driver
2 MPU Speed Sensors
1 Analog Output
2 Analog Inputs
8 Discrete (Switch) Inputs
4 Discrete (Relay Driver) Outputs
2 Serial Ports
• 1 CAN Port
The following is an example of the typical hardware needed for a 2300E system controlling a single prime
mover and generator:
A 2300E electronic control
An external 18 to 36 Vdc power source
Two speed-sensing devices, typically magnetic pickups (MPUs)
A proportional actuator to position the fuel-metering device
Current and potential transformers for measuring the load carried by the generator
The frequency from the magnetic pickup must be within the range of 100 to 25 000 Hz at rated speed.
The 2300E speed range needs to be configured using an external computer during installation.

This chapter contains general installation instructions for the 2300E control. Power requirements,
environmental precautions, and location considerations are included to determine the best location for the
control. Additional information includes unpacking instructions, electrical connections, and an installation
check- out procedure.
Before handling the control, read all of this chapter and “Electrostatic Discharge Awareness” at the
beginning of this manual. Be careful when unpacking the electronic control. Check the control for signs of
damage such as bent or dented panels, scratches, and loose or broken parts. If any damage is found,
immediately notify the shipper. Do not take the control out of the ESD bag it ships in until ESD
precautions are in place. Keep yourself discharged while handing the unit outside the ESD bag, at least
until it is grounded.
Power Requirements
The 2300E control requires a voltage source of 18 to 36 Vdc, with a current capacity of at least 600 mA
for operating power. If a battery is used for operating power, an alternator or other battery charging device
is necessary to maintain a stable supply voltage. The battery charging device should be suppressed from
load dump events or the power bus must have central suppression. The 2300E does not have sufficient
capability to withstand all battery load dump events.
