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.
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.
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 to troubleshoot unstable engine speed at no load with Woodward EGCP-2 Controller?
If the engine speed is unstable when the unit is at no load, 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.
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.
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.
What causes overload or reverse power during process control operation with a Woodward Controller?
If process control operation causes overload or reverse power, the PROCESS ACTION set point in the process control menu may be set for the incorrect action. Appropriately set the PROCESS ACTION set point in the process control menu.
What should I do if the displayed generator voltages are very small on my Woodward EGCP-2 Controller?
If the displayed generator voltages are very small, there are a couple of potential causes: * There may be faulty wiring of the generator Potential Transformers (PTs). Verify the wiring. * The generator PT inputs may be improperly calibrated. Calibrate the appropriate PT input channel(s).
What to do if my Woodward EGCP-2 Controller synchronizer displays a small phase difference, but the measured phase difference is large?
If the synchronizer displays a small phase difference, but the measured phase difference is large, consider the following: * The Generator A phase PT input could be L-L while the bus A phase PT input is L-N, or vice versa. Verify that the Generator A phase PT input and bus A phase PT input are the same form (i.e., L-N or L-L). * The bus and/or generator PT inputs may not be A phase. Verify that the bus and generator PT inputs are A phase. * The synchronizer may be improperly calibrated. Calibrate the synchronizer.
Why does my Woodward EGCP-2 synchronizer match phase but never closes the breaker?
If the synchronizer matches phase but never closes the breaker/contactor, it could be due to: * The Synchronizer Mode set point in the synchroscope menu being set to CHECK. Set the Synchronizer Mode to the appropriate setting. * The Dwell Time set point in the synchroscope menu being too large. Reduce the Dwell Time set point in the synchroscope menu.
