PRODUCT DESCRIPTION

Do NOT use the minimum-fuel contact as a part of any emergency stop sequence. The emergency may be caused by a governor malfunction which would also cause a malfunction of the minimumfuel feature. Use of the minimum-fuel contact for an emergency stop sequence could cause overspeed of the prime mover and mechanical 

damage and personal injury, including death.

Benefits:

Even though governor faults cause improper prime mover operation, improper 

prime mover operation can be also caused by other items such as low fuel 

pressure. When the prime mover stops working properly, find out which part is 

defective. Do this by: 

1. Substituting, if available, a part that works for the one suspected of causing 

the problem. 

2. Simplifying the system. Remove options and observe performance after 

each removal. 

3. Testing the parts suspected of causing the problem. Follow the 

manufacturer’s instructions or set up input and operating conditions which 

produce known outputs. 

To test the EPG, use Chapter 2 to verify that the installation is correct and 

perform the installation check. Those checks are the best way to test the EPG. 

The Preset Rated Speed section (under Step 6 of the Installation Checks in 

Chapter 2) is the best test of the EPG’s ability to control speed. It requires the 

use of a signal generator with an isolated output. If appropriate, do the checks for 

Paralleled Generator Applications with the Load Sensor (referenced in Chapter 2, 

manual 82313). 

Other Checks 

Do the installation checks described in the previous paragraph first. Then check 

the following: 

1. If the prime mover is stable at some speeds or power outputs but oscillates 

at others, the linkage may not be compatible with the fuel control. Refer to 

Linkage Compatibility under Actuator Mounting and Linkage in Chapter 2. 

2. If the prime mover oscillates at low frequency (about 1 Hz) and the Gain and 

Stability adjustments (in Chapter 2) are correct, then friction in the linkage 

may be the cause. 

· Disconnect the actuator from the fuel control. 

· Manually stroke the fuel control linkage from stop to stop as if the 

actuator were moving it. The linkage must move freely without friction 

and without backlash. Lubricate or replace linkage or fuel control parts 

as required. 

3. If the prime mover is unstable only when load sharing, verify that: 

· Load sensor CTs and PTs are wired correctly. 

· Voltage regulator droop or cross current compensation is set correctly. 

· The voltage regulator is not intermittent or otherwise faulty. 

 If the problem is still there, reduce the load gain a little and set the load gain 

pot on all other load sensors in the system for the same load signal at full 

load. It may be necessary to reduce the load signal to 3 volts in extreme 

cases. Consult with your authorized Distributor or with Woodward in such 

cases.
