What to do if the Woodward EGCP-2 Controller contactor closes briefly and then opens?
- A
  Ashley BrownAug 31, 2025
  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.

What should I do if phase power factors do not agree on my Woodward EGCP-2 Controller?
- M
  Mary Hughes DVMSep 10, 2025
  If phase power factors do not agree and two of the three phases are extremely far out of range, the CT’s are likely connected to incorrect phase inputs. Verify that the CT’s are connected to the appropriate input terminals. Note: The engine generator set must be off to safely open circuit a current transformer.

How do I resolve unstable real load control in Woodward Controller when paralleled with the mains source?
- R
  rogerscraigAug 30, 2025
  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 to fix a Woodward EGCP-2 Controller that maintains a constant power factor load rather than a constant VAR?
- D
  Derrick GarciaSep 12, 2025
  If the unit maintains a constant power factor load rather than a constant VAR when paralleled with the mains source, the VAR/PF set point is likely set to PF CONTROL. Appropriately set the VAR/PF set point in the reactive load control menu.

How do I resolve unstable reactive load control in Woodward Controller when paralleled with the mains source?
- J
  Jacob SpenceSep 12, 2025
  If the reactive load control is unstable when paralleled with the mains source, the reactive load control dynamics in the reactive load control menu are likely improperly set up. Tune the reactive load control dynamics in the reactive load control menu.

Why does my Woodward EGCP-2 Controller sequence on more than one gen-set when the system load is large enough?
- M
  Miss Kimberly Bowers DVMSep 14, 2025
  If more than one set is sequenced on line when the system load is large enough to require additional gen-sets, it may be because: * The NEXT GENSET DELAY set point in the sequencing menu is too short. Increase the NEXT GENSET DELAY set point in the sequencing menu. * The MAX START TIME set point in the sequencing menu is too short. Increase the MAX START TIME set point in the sequencing menu.

Why does the starter motor stay engaged after the engine starts with my Woodward Controller?
- N
  Nancy StewartAug 27, 2025
  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?
- T
  travis26Aug 27, 2025
  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 doesn't my Woodward EGCP-2 start the engine when I issue a start command?
- L
  Laura CollinsAug 26, 2025
  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 Controller unit does not power up?
- G
  Gary GuzmanAug 26, 2025
  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.
