Warnings and Notices 

 

Important Definitions 

This is the safety alert symbol. It is used to alert you to potential 
personal injury hazards. Obey all safety messages that follow this 
symbol to avoid possible injury or death. 

 

DANGER

—Indicates a hazardous situation which, if not avoided, will result 

in death or serious injury. 

 

WARNING

—Indicates a hazardous situation which, if not avoided, could 

result in death or serious injury. 

 

CAUTION

—Indicates a hazardous situation which, if not avoided, could 

result 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 / 

Overpressure 

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. 

 

 

 

Personal Protective 

Equipment

 

The products described in this publication may present risks that 
could lead to personal injury, loss of life, or property damage. Always 
wear the appropriate personal protective equipment (PPE) for the job 
at hand. Equipment that should be considered includes but is not 
limited to: 
 

Eye Protection 

 

Hearing Protection 

 

Hard Hat 

 

Gloves 

 

Safety Boots 

 

Respirator 

Always read the proper Material Safety Data Sheet (MSDS) for any 
working fluid(s) and comply with recommended safety equipment.

 

 

 

Start-up

 

Be prepared to make an emergency shutdown when starting the 
engine, turbine, or other type of prime mover, to protect against 
runaway or overspeed with possible personal injury, loss of life, or 
property damage. 

 

 

 

Automotive 

Applications

 

On- and off-highway Mobile Applications: Unless Woodward's control 
functions as the supervisory control, customer should install a 
system totally independent of the prime mover control system that 
monitors for supervisory control of engine (and takes appropriate 
action if supervisory control is lost) to protect against loss of engine 
control with possible personal injury, loss of life, or property damage.

Battery Charging 

Device

 

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. 

 
 
 
 

Electrostatic Discharge Awareness 

 

 

 

Electrostatic 

Precautions

 

Electronic controls contain static-sensitive parts. Observe the 
following precautions to prevent damage to these parts: 

 

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). 

 

Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) 
around printed circuit boards. 

 

Do not touch the components or conductors on a printed circuit 
board with your hands or with conductive devices. 

To prevent damage to electronic components caused by improper 
handling, read and observe the precautions in Woodward manual 

82715

, 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 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.  Do not remove the printed circuit board (PCB) from the control cabinet 

unless absolutely necessary. If you must remove the PCB from the control 
cabinet, follow these precautions: 

 

 

Do not touch any part of the PCB except the edges. 

 

 

Do not touch the electrical conductors, the connectors, or the 
components with conductive devices or with your hands. 

 

 

When replacing a PCB, keep the new PCB in the plastic antistatic 
protective bag it comes in until you are ready to install it. Immediately 
after removing the old PCB from the control cabinet, place it in the 
antistatic protective bag.
