Why Woodward 8405-024 actuator drives opposite direction?
The actuator might be driving in the opposite direction because the actuator drive wires and position feedback are connected with reverse polarity. To solve this, check the wiring to ensure it has the correct polarity.
What to do if Woodward 8405-024 Controller actuator drives into max stop with a command to min fuel?
If the actuator drives into the max stop when a command to min fuel is applied, it could be due to incorrectly connected actuator drive or position feedback signals. Check the wiring for proper polarity of the actuator drive wires. Also, verify the polarity of the actuator position feedback input wiring.
How to fix Woodward Controller actuator driving into min stop with mid fuel command?
If the actuator drives into the minimum stop when a command to mid fuel is applied, it may be due to the position command signal not being received correctly. Check the wiring for proper polarity of the position command input leads. Also, ensure that the position command input has a good connection to the input signal by inspecting the wiring.
What to do if Woodward 8405-024 Controller actuator and control system do not respond?
If the actuator and control system are unresponsive with all voltage outputs at 0 V, the actuator and driver may not be receiving power. Check the wiring for proper polarity of the input power leads. Also, verify that the input power leads have a secure connection to the battery + or battery –.
