Overview

Essential details：2301E 8273-1011 2301E Digital Load Sharing and Speed Control for Engines Woodward

The Woodward 2301E controls load sharing and speed of generators driven by diesel or gaseous engines. (These power sources are referred to as “prime movers” throughout this manual.) The 2301E is a microprocessor-based digital control designed to include the functions of and be compatible with 2301A and 2301D load sharing controls. The increased flexibility of software allows the 2301E to include control functions that required additional equipment in previous versions of 2301A and 2301D control systems. The 2301E therefore is suitable for upgrading existing control systems for increased functionality in new installations.

The 2301E has the following Woodward part numbers:

8273-1011

2301E Load Sharing and Speed Control, 24 Vdc input, Ordinary Locations

8273-1012

2301E 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 2301E 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 (either Servlink / Watch Windows or Control Assistant) can be downloaded from our website at www.woodward.com.

The 2301E provides control in either isochronous mode, droop mode, or base load mode. The 2301E will allow for soft load transfer when being added to or removed from a bus.

2301E 8273-1011

The isochronous mode is used for constant prime mover speed with:

 Single prime mover operation or

 Two or more prime movers controlled by Woodward analog load sharing control systems on an isolated bus

The droop mode is used for speed control as a function of load with:

 Single prime mover operation on an infinite bus or

 Parallel operation of two or more prime movers

The base load mode provides constant load level operation against a bus with the load controlled by the 2301E.

 The load setting is set by a fixed reference,

 External input analog input,

 External contact control of the reference
