What does it mean if the 2301A control does not cut back the actuator voltage on my Woodward Control Unit?
If the control does not cut back the actuator voltage [T20 (+) and T21 (–)] until the speed setting is completely counterclockwise, the 2301A control may be faulty, or may have the wrong speed range.
What does it mean if the Start Fuel Limit is inactive in my Woodward Control Unit?
On power up, the Fuel Limit can be bypassed if the MPU signal clears in less than 1 second.
What to do if my Woodward Control Unit prime mover will not start and the actuator isn't moving?
If your prime mover isn't starting and the actuator isn't moving to the start-fuel position, here are a few things to check: * First, ensure proper voltage from terminals 16 (+) to 15 (–). If it's a DC system and the polarity is incorrect, reverse the leads. * If there's voltage at control terminals 20 (+) and 21 (–) but the actuator remains still, inspect the wiring to the actuator for any opens or shorts. * Also, the start fuel limit might be set too low. Try turning the start fuel limit clockwise until the prime mover starts. * Make sure that actuator moves approximately 2/3 of its travel from no load to full load. * Check the magnetic-pickup output voltage at speeds above idle—it should be at least 1.0 Vrms.
What to do if my Woodward Control Unit is faulty?
If you suspect a faulty control, consider replacing it.
What to do if the speed sensor signal isn't clearing the failed speed signal circuit on my Woodward Control Unit?
If the speed sensor signal isn't clearing the failed speed signal circuit, check the wiring for a proper connection.
How to troubleshoot a faulty speed trim potentiometer in a Woodward Control Unit?
To troubleshoot a faulty speed trim potentiometer, turn the power OFF and then check the speed trim potentiometer(s) using an ohmmeter.
What to do if terminals 23 and 24 are open on my Woodward Control Unit?
If you find that terminals 23 and 24 are open, verify that they are jumpered if an optional external speed trim is not being used.
What to check if the Minimum Fuel contact is open on my Woodward Control Unit?
If the Minimum Fuel contact is open, check T 17. For normal operation, the minimum-fuel contact must be closed.
What to do if the LOW IDLE SPEED setting is too low on my Woodward Control Unit?
If the LOW IDLE SPEED setting appears to be too low, adjust the LOW IDLE SPEED potentiometer clockwise to increase it.
What to do if the speed setting is too low on initial start of my Woodward Control Unit?
If the speed setting is too low on initial start, it's possible the control is the wrong speed range. Check the speed sensor frequency against the control part number. Also, the speed setting may be lower than the cranking speed.
