Why is the speed of my Woodward 723PLUS Controller engine not regulated?
If your Woodward Controller engine speed is not regulated, verify the actuator is capable of reaching the minimum and maximum fuel rack positions, as the issue may be due to improper linkage adjustment.
Why does my Woodward 723PLUS Controller engine overspeed or smoke excessively on startup?
If your Woodward Controller engine overspeeds on start or causes excessive smoke, it might be due to the start fuel limit being set too high. To resolve this, reduce the start fuel limit to a level slightly above (10%–20%) the percent actuator driver level needed to run the engine at idle speed.
What to do if Woodward 723PLUS Controller engine won't start but the actuator moves to the start fuel position?
If your Woodward Controller engine will not start and the actuator is moving to the start fuel position, check that the linkage from the actuator to the fuel rack is properly connected. Also, check the start fuel limit level, as it might be set too low.
What to do if Woodward 723PLUS Controller engine won't start and actuator isn't moving to start fuel position?
If your Woodward Controller engine will not start and the actuator is not moving to the start fuel position, the cause might be no or incorrect power supply voltage if the CPU OK LED is not illuminated. Additionally, verify the actuator voltage output from the 723PLUS control during cranking; it should not remain at 0 Vdc (forward acting) or 7 Vdc (reverse acting).
Why does my Woodward 723PLUS engine overspeed on start?
If your Woodward Controller engine overspeeds on start, it could be due to an actuator and/or linkage problem. Verify that the fuel rack is not binding and the linkage is properly adjusted.
How to fix Woodward 723PLUS when POWER SUPPLY OK LED is not illuminated?
If the POWER SUPPLY OK LED on your Woodward Controller is not illuminated, it indicates a failed power supply. Replace the 723PLUS control.
How to troubleshoot unequal torque sharing in Woodward Controller engines?
If your Woodward Controller engines do not share torque equally, verify the torque inputs are equal (±2.5%) with the hand held programmer. The cause might be improper torque sensor transducer or default percent actuator calibration.
What causes a Woodward 723PLUS Controller engine to be unstable and erratic?
If your Woodward Controller engine will not stabilize and the control is erratic or varies with load, verify the proper dynamics are being adjusted at the proper time. The cause might be speed control dynamics adjustments.
Why doesn't my Woodward Controller engine respond to remote reference changes?
If your Woodward Controller engine does not accelerate and/or decelerate when the remote reference is moved, it may be because the unit is clutched in as a slave or appears to be clutched in as a slave. If the unit is clutched in last, it becomes the slave unit.
What does a CPU watchdog fault mean on a Woodward 723PLUS?
If a CPU watchdog fault occurs in your Woodward 723PLUS Controller, it generally indicates a CPU failure. In this case, the 723PLUS control will need to be replaced.
