How to fix discrete inputs not showing active on Woodward Control Unit?
If discrete inputs don’t show active in the I/O STATUS screen when switches are activated on your Woodward Control Unit, it could be caused by faulty wiring of the discrete input switches. Verify the wiring of these switches.
Why generator voltage fluctuates on Woodward Control Unit?
If the generator voltage fluctuates or is unstable at no load on the generator with your Woodward Control Unit, the AVR dynamics might be improperly set up. You should tune the AVR dynamics for stable operation.
What to do if the Woodward EGCP-2 Controller contactor closes briefly and then opens?
If the contactor closes for a brief moment and then opens, consider the following: * The C B CONTROL set point in the configuration menu might be set for BREAKER. Appropriately set the C B CONTROL set point in the configuration menu. * The C B HOLD TIME set point in the synchroscope menu might be too short. Increase the C B HOLD TIME set point in the synchroscope menu. * There could be faulty wiring on the C.B. Aux contacts. Verify the wiring of the C.B. Aux contacts to the EGCP-2 input.
How to troubleshoot unstable engine speed/load with Woodward Controller?
If the engine speed/load has an instability that fluctuates very quickly, it's likely that the speed control dynamics are improperly set up. You'll need to tune the speed control dynamics for stable operation. Consult the speed control manufacturer’s instruction manual for detailed instructions.
What to do if my Woodward EGCP-2 Controller unit does not power up?
If your Woodward Controller unit isn't powering up, there are a couple of things to check: * First, make sure the input power supply is connected correctly to terminals 1 and 2, and that it's providing between 9 and 32 Vdc. * Second, verify that the polarity of the power supply is correct.
Why doesn't my Woodward EGCP-2 start the engine when I issue a start command?
If the start command isn't starting the engine, it could be due to a few reasons: * The configuration menu might not have been properly accepted or entered. Ensure all “*” and “#” symbols are removed from the display in the Configuration menu. * There may be an active alarm condition. You'll need to commit or reset any existing alarms. * The relay output contacts might not be properly connected to the engine starter or fuel solenoid. Double-check the wiring of these relay output contacts.
What to do if my Woodward EGCP-2 displays matched phase, but measured phase difference is ~180 degrees?
If your Woodward Controller shows a matched phase but the measured phase difference is around 180 degrees, or the breaker crash parallels the set 180 degrees out of phase when closed, the generator or bus PT might have reversed polarity due to faulty wiring. Verify the correct polarity of the generator and bus PT inputs.
Why does the starter motor stay engaged after the engine starts with my Woodward Controller?
If the starter motor remains engaged after the engine starts, it could be due to: * The Crank Cutout set point in the Engine Control menu being too large. Adjust the Crank Cutout set point to the appropriate value. * An inadequate MPU signal to the EGCP-2 input. Verify the MPU wiring and ensure there's an adequate MPU signal at the input to the EGCP-2 control.
What causes a Woodward EGCP-2 Controller unit to lose power and reset when cranking?
If your Woodward Controller loses power, resets, and runs a RAM test when a crank command is issued, it could be due to: * The battery being too weak for the starter motor's current demand. Consider installing a higher capacity battery or a more efficient starter motor. * Faulty wiring of the power supply to the EGCP-2 control. Verify the wiring of the power supply.
Why is my Woodward EGCP-2 Controller's generator voltage fluctuating at no load?
If the generator voltage fluctuates or is unstable at no load, the AVR dynamics are likely improperly set up. Tune the AVR dynamics for stable operation. Refer to the AVR manufacturer’s instruction manual for detailed guidance.
