The latest version of most publications is available at: www.woodward.com/publications If your publication is not there, please contact your customer service representative to get the latest copy. WARNING—OVERSPEED PROTECTION The engine, turbine, or other type of prime mover should be equipped with an overspeed shutdown device to protect against runaway 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 the prime mover control system. An overtemperature or overpressure shutdown device may also be needed for safety, as appropriate. WARNING—PROPER USE  Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical, or other operating limits may cause personal injury and/or property damage, including damage to the equipment. Any such unauthorized modifications: (i) constitute misuse and/or negligence within the meaning of the product warranty thereby excluding warranty coverage for any resulting damage, and (ii) invalidate product certifications or listings.   CAUTION—POSSIBLE DAMAGE TO EQUIPMENT OR PROPERTY CAUTION—BATTERY CHARGING To prevent damage to a control system that uses an alternator or battery-charging device, make sure the charging device is turned off before disconnecting the battery from the system. CAUTION—ELECTROSTATIC DISCHARGE Electronic controls contain static-sensitive parts. Observe the following precautions to prevent damage to these parts. ã   Discharge body static before handling the control (with power to the control turned off, contact a grounded surface and maintain contact while handling the control). ã    Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards. ã   Do not touch the components or conductors on a printed circuit board with your hands or with conductive devices. IMPORTANT DEFINITIONS ã    A WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. ã    A CAUTION indicates a potentially hazardous situation which, if not avoided, could result in damage to equipment or property. ã    A NOTE provides other helpful information that does not fall under the warning or caution categories.
