Manual 823892301A LSSCWarnings and NoticesImportant Definitions This is the safety alert symbol. It is used to alert you to potentialpersonal injury hazards. Obey all safety messages that follow thissymbol to avoid possible injury or death.DANGER—Indicates a hazardous situation which, if not avoided, will resultin death or serious injury.WARNING—Indicates a hazardous situation which, if not avoided, couldresult in death or serious injury.CAUTION—Indicates a hazardous situation which, if not avoided, couldresult in minor or moderate injury.NOTICE—Indicates a hazard that could result in property damage only(including damage to the control).IMPORTANT—Designates an operating tip or maintenance suggestion.Overspeed /Overtemperature /OverpressurePersonal ProtectiveEquipmentThe engine, turbine, or other type of prime mover should beequipped with an overspeed shutdown device to protect againstrunaway or damage to the prime mover with possible personal injury,loss of life, or property damage.The overspeed shutdown device must be totally independent of theprime mover control system. An overtemperature or overpressureshutdown device may also be needed for safety, as appropriate.The products described in this publication may present risks thatcould lead to personal injury, loss of life, or property damage. Alwayswear the appropriate personal protective equipment (PPE) for the jobat hand. Equipment that should be considered includes but is notlimited to: Eye Protection Hearing Protection Hard Hat Gloves Safety Boots RespiratorAlways read the proper Material Safety Data Sheet (MSDS) for anyworking fluid(s) and comply with recommended safety equipment.Start-upAutomotiveApplicationsWoodwardBe prepared to make an emergency shutdown when starting theengine, turbine, or other type of prime mover, to protect againstrunaway or overspeed with possible personal injury, loss of life, orproperty damage.On- and off-highway Mobile Applications: Unless Woodward's controlfunctions as the supervisory control, customer should install asystem totally independent of the prime mover control system thatmonitors for supervisory control of engine (and takes appropriateaction if supervisory control is lost) to protect against loss of enginecontrol with possible personal injury, loss of life, or property damage.3
2301A LSSCManual 82389To prevent damage to a control system that uses an alternator orbattery-charging device, make sure the charging device is turned offbefore disconnecting the battery from the system.Battery ChargingDeviceElectrostatic Discharge AwarenessElectrostaticPrecautionsElectronic controls contain static-sensitive parts. Observe thefollowing precautions to prevent damage to these parts: Discharge body static before handling the control (with power tothe control turned off, contact a grounded surface and maintaincontact while handling the control). Avoid all plastic, vinyl, and Styrofoam (except antistatic versions)around printed circuit boards. Do not touch the components or conductors on a printed circuitboard with your hands or with conductive devices.To prevent damage to electronic components caused by improperhandling, read and observe the precautions in Woodward manual82715, Guide for Handling and Protection of Electronic Controls,Printed Circuit Boards, and Modules.Follow these precautions when working with or near the control.1. Avoid the build-up of static electricity on your body by not wearing clothingmade of synthetic materials. Wear cotton or cotton-blend materials as muchas possible because these do not store static electric charges as much assynthetics.2. Do not remove the printed circuit board (PCB) from the control cabinetunless absolutely necessary. If you must remove the PCB from the controlcabinet, follow these precautions: Do not touch any part of the PCB except the edges. Do not touch the electrical conductors, the connectors, or thecomponents with conductive devices or with your hands. When replacing a PCB, keep the new PCB in the plastic antistaticprotective bag it comes in until you are ready to install it. Immediatelyafter removing the old PCB from the control cabinet, place it in theantistatic protective bag.4Woodward

Manual 823892301A LSSCChapter 1.General InformationDescriptionThe 9905/9907 series of the Woodward 2301A controls load sharing and speedof generators driven by diesel or gasoline engines, or steam or gas turbines.These power sources are referred to as “prime movers” throughout this manual.The control is housed in a sheet-metal chassis and consists of a single printedcircuit board. All potentiometers are accessible from the front of the chassis.The 2301A provides control in either isochronous or droop mode.The isochronous mode is used for constant prime mover speed with: Single-prime-mover operation; Two or more prime movers controlled by Woodward load sharing controlsystems on an isolated bus; Base loading against an infinite bus with the load controlled by an AutomaticPower Transfer and Load (APTL) Control, an Import/Export Control, a GeneratorLoading Control, a Process Control, or another load-controlling accessory.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 following is an example of the typical hardware needed for the 2301Asystem controlling a single prime-mover and generator: A 2301A electronic control An external 20 to 40 Vdc power source for low-voltage models; 90 to 150Vdc or 88 to 132 Vac for high-voltage models A proportional actuator to position the fuel-metering device, and Current and potential transformers for measuring the load carried by thegenerator.ApplicationsThe 2301A 9905/9907 series electronic controls have switch-selectable speedranges. Any of these control models can be set to operate within one of thefollowing rated speed ranges: 500 to 1500 Hz 1000 to 3000 Hz 2000 to 6000 Hz 4000 to 12 000 HzThe speed range is factory set for 2000 to 6000 Hz. Refer to the insidecover to change speed range and prevent possible overspeed. Usingthe wrong speed range could cause an overspeed with resultingdamage to equipment and/or personal injury or death.The Rated Speed potentiometer is the only multi-turn pot in thiscontrol. All other pots are single-turn. Take care not to turn these potsbeyond their stops.Woodward7
2301A LSSCManual 82389These controls are available for forward- or reverse-acting applications, and foruse with either single or tandem actuators. Models for three different actuatorcurrent ranges are available, as well as a high-voltage model (90 to 150 Vdc or88 to 132 Vac, 45 to 440 Hz), and a low-voltage model (20 to 40 Vdc). The highvoltage model is identified as such on the front; the low voltage model is not.In reverse-acting systems, the actuator calls for more fuel when the actuatorvoltage decreases. Complete loss of voltage to the actuator will drive the actuatorto full fuel. This allows a backup mechanical ballhead governor to take controlrather than shut down the prime mover as would a direct-acting system.An optional deceler
Two or more prime movers controlled by Woodward load sharing control systems on an isolated bus; Base loading against an infinite bus with the load controlled by an Automatic Power Transfer and Load (APTL) Control, an Import/Export Control, a Generator Loading Control, a Process Control, or another load-controlling accessory.

Active load sharing (kW) Generators running in parallel operation. Through connection of dedicated load sharing lines all FlexGen controllers can handle paralleling of a generator to other generators controlled by FlexGen, C6200, SIGMA, T4400, T4800 or B6000 load sharing units.
