Why does my Woodward EGCP-2 Controller breaker close relay stay energized?
If the breaker close relay stays energized when a close command is given and never issues an open command, the C B CONTROL set point might be set for CONTACTOR. Appropriately set the C B CONTROL set point in the configuration menu.
Why is my Woodward EGCP-2 Controller unit not adequately matching phase?
If the unit never adequately matches phase, it could be due to: * The Synchronizer Mode set point in the synchroscope menu being set to PERMISSIVE. Set the Synchronizer Mode to the appropriate setting. * The synchronizer dynamics in the synchroscope menu being improperly set up. Tune the synchronizer dynamics.
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.
Why does my Woodward EGCP-2 Controller not voltage match?
If the synchronizer won’t voltage match, it's possible that the VOLTAGE MATCHING set point in the synchroscope menu is DISABLED. Enable the VOLTAGE MATCHING set point in the synchroscope menu.
How do I resolve unstable real load control in Woodward Controller when paralleled with the mains source?
If the real load control is unstable when paralleled with the mains source, the real load control dynamics in the real load control menu are likely improperly set up. Tune the real load control dynamics in the real load control menu.
How do I fix a Woodward Controller that won't close to a dead bus?
If the unit won’t close to a dead bus, it could be due to: * A multiple unit system with the DEADBUS CLOSING set point in the configuration menu set to DISABLED. Enable the DEADBUS CLOSING set point in the configuration menu. * The synchronizer set point is set to CHECK. Set the synchronizer mode to the appropriate setting.
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.
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 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 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.
