Why is my Woodward Controller engine unstable with no load?
Engine instability with no load can be due to several factors. The speed filter setting might be too low, requiring improved PID tuning. Fuel restriction could also be a cause, so check the actuator linkage. Also, the battery voltage may be too low.
What causes engine instability with load in my Woodward DPG-2223-00 system?
If your engine exhibits instability under load, potential causes include fuel restriction, which can be addressed by checking the actuator linkage. Also, the battery voltage may be too low.
What to do if load sharing does not work with my Woodward DPG-2223-00?
If load sharing is not functioning correctly, measure the ILS input signal to see if the measurement is between 2.300 and 2.700 Vdc. Also, use shielded wiring.
