PRODUCT DESCRIPTION

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.

Benefits:

Prime mover will not 

start. Actuator not 

moving to start-fuel 

position (cont.). 

LOW IDLE SPEED setting may be 

too low. 

Adjust LOW IDLE SPEED potentiometer cw. 

Minimum Fuel contact open. See 

"MINIMUM FUEL CONTACT" in 

Chapter 2. 

If voltage exceeds 3 volts, the 

switch or wiring is faulty. 

Check switch at terminal 3. Minimum-fuel contact 

must be closed for normal operation. Check for 0 to 

3 Vdc from terminal 2 (+) to 3 (–) on low-voltage 

controls. (Between terminals 6 (+) and 3 (–) on 

high-voltage controls. 

MPU not supplying signal to 

control. 

Check MPU wiring for proper connection, check 

shields for proper installation. 

Magnetic pickup may be open-circuited or shorted. 

Check resistance with the leads disconnected from 

the control. Resistance should be about 100 to 300 

W. 

Prime mover will not 

start. Actuator not 

moving to start-fuel 

position. 

Terminals 11 and 12 are open. Verify that terminals 11 and 12 are jumpered if 

optional external speed trim is not used. 

Check the voltage from terminal 11 (+) to 12 (–). It 

should be less than 2 volts. 

Faulty speed trim potentiometer. With power OFF, check speed-trim potentiometer 

with an ohmmeter. 

Faulty 2301A Speed Control. Replace unit. 

Prime mover 

overspeeds only on 

starts. 

Ramp adjustment. Increase RAMP TIME (cw). This decreases 

acceleration rate (from low idle to rated.) 

RATED SPEED setting too high. Set RATED SPEED as described in Chapter 3. 

Amplifier adjustment. 2301A may be adjusted for sluggish operation, 

causing overspeed on start. Slowly adjust GAIN for 

fastest stable response. RESET may be adjusted 

too low. Increase RESET setting. 

Engine is malfunctioning. Verify that the fuel rack is not binding and the 

linkage is properly adjusted. Determine if the fuel 

rack is quickly following the actuator input voltage. 

Verify proper operation of overspeed protection 

devices to determine if a shutdown is occurring 

without an overspeed condition. 

2301A Speed Control. If the control does not cut back the actuator voltage 

when the speed setting is completely ccw the 

2301A control may be faulty, or may have the 

wrong speed range. If the voltage is cut back, 

(increased on reverse acting controls) look for a 

problem in the linkage or actuator. 

Prime mover 

overspeeds after 

operating at rated 

speed for some time. 

Prime mover. Check for proper operation of prime-mover fuel 

system. If actuator moves toward minimum fuel 

during overspeed, problem is in fuel system. 

MPU and 2301A control. Check MPU voltage at speeds above idle (at least 

1.0 Vrms). If MPU fails and the switch at terminal 4 

is closed, the 2301A will call for maximum fuel. 

2301A dynamics adjustment. Control the prime mover manually at rated speed 

and adjust the RATED SPEED setting fully ccw. If 

the output voltage is not zero, replace the control. 

(Voltage should be about 7 volts for 0-200 mA 

reverse acting controls or maximum current time 

actuator resistance for controls of other ratings.) 

Prime mover has 

momentary speed 

change when 

adjusting GAIN. 

GAIN adjustment made too 

quickly. 

Make GAIN adjustment slowly. Momentary speed 

change when adjusting GAIN is normal.
