PRODUCT DESCRIPTION

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.

Benefits:

Set the IDLE potentiometer (pot) (if used) to mid-position. 

7. Set the RATED speed pot fully counterclockwise (to minimum speed 

setting). 

8. Set the GAIN and STABILITY pots to mid-position. 

9. Set START FUEL LIMIT clockwise (if applicable). 

10. Start the engine or turbine, following manufacturer's instructions. 

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. 

Verify: 

· MPU voltage between terminals 5 and 6 at least 1.5 Vrms while cranking? 

(For small gears, it may be necessary to decrease the MPU clearance). Do 

not decrease below 0.25 mm (.010 inches). 

· Actuator should go to maximum fuel position when the starter turns engine 

or turbine. (If applicable, Start Fuel Limit must be fully clockwise.) 

· When the engine or turbine starts and comes to speed, the actuator arm 

should move toward minimum-fuel position. 

11. Adjust the GAIN pot to the stable region between low-frequency and highfrequency oscillation. 

12. If there is a low-frequency oscillation which does not stop when the GAIN 

pot is adjusted, turn the STABILITY pot slightly clockwise and try the GAIN 

pot adjustment again. Continue adjusting the STABILITY pot slightly 

clockwise, then readjusting the GAIN pot, until the engine runs at a steady 

speed. 

 If there is a high-frequency oscillation which will not stop, even when the 

GAIN pot is fully counterclockwise, adjust the STABILITY pot slightly 

counterclockwise until the high-frequency oscillation stops. 

Speed Settings 

13. Adjust the RATED SPEED pot for the desired rated speed. 

14. Set the IDLE SPEED pot for the desired idle speed. 

15. Close the IDLE/RATED switch. 

16. Adjust transient response. Simulate a transient by manually bumping the 

linkage. 

 To decrease settling time (may increase ringing) after a transient, turn the 

GAIN pot clockwise slightly, then turn the STABILITY pot as required to 

eliminate oscillation and to obtain desired response. Repeat if necessary
