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.

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.
