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:

Speed Trim 

A speed trim potentiometer or digital reference unit is connected to terminals 11 

and 12. Use a high quality 100 W, 10-turn potentiometer (Woodward part 1657-

537 or equivalent) to provide about ±5% speed adjustment. Terminals 11 and 12 

must be jumpered if the speed trim potentiometer or digital reference unit is not 

used. The 2301A Speed Control will have a jumper installed in the factory and 

this must be removed if a speed-trim device is used. 

Droop Potentiometer 

A 2K potentiometer may be connected to provide a maximum of about 8% droop. 

Connect the potentiometer (ccw) to terminal 15, (cw) to terminal 14, and wiper to 

terminal 13. If droop is not desired make no connections to terminals 13 and 14. 

Switch Options 

Minimum Fuel Contact 

The minimum-fuel contact between terminals 2 and 3 on the low-power models 

and 3 and 6 on the high-power models is intended as an optional means for a 

normal shutdown of the prime mover. The contact is connected as shown on the 

plant wiring diagram for the particular control. If a minimum fuel contact is not 

used, the terminals must be permanently jumpered. 

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. 

Failed Speed Signal Override 

Circuits in the 2301A Speed Control constantly monitor the signal from the MPU. 

Should this signal be below a minimum threshold the control sends a minimum 

fuel signal to the actuator (maximum fuel signal on a reverse acting control).
