Follow these precautions when working with or near the control.

1. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials. Wear cotton or cotton-blend materials as much as possible because these do not store static electric charges as much as synthetics.

2. Touch your finger to a grounded surface to discharge any potential before touching the control, smart valve, or valve driver, or installing cabling connectors. Alternatively, ESD mitigation may be used as well: ESD smocks, ankle or wrist straps and discharging to a reference grounds surface like chassis or earth are examples of ESD mitigation.

? ESD build up can be substantial in some environments: the unit has been designed for immunity deemed to be satisfactory for most environments. ESD levels are extremely variable and, in some situations, may exceed the level of robustness designed into the control. Follow all ESD precautions when handling the unit or any electronics.

o I/O pins within connectors have had ESD testing to a significant level of immunity to ESD, however do not touch these pins if it can be avoided.

? Discharge yourself after picking up the cable harness before installing it as a precaution.

o The unit is capable of not being damaged or improper operation when installed to a level of ESD immunity for most installation as described in the EMC specifications. Mitigation is needed beyond these specification levels.

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 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 .

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.

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.
