What should I do if phase power factors do not agree on my Woodward EGCP-2 Controller?
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 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.
What to do if I/O STATUS shows relay is energized but alarm does not occur on Woodward Control Unit?
If the I/O STATUS screen on your Woodward Control Unit shows a relay is energized, but the corresponding action (like an alarm) does not occur, the problem is likely due to faulty wiring of the relay output contacts. Verify the wiring of the relay output contacts to ensure they are correctly connected.
How do I fix a Woodward EGCP-2 that carries an improper proportion of reactive load during isochronous load sharing?
If the unit carries an improper proportion of reactive load during isochronous load sharing: * The Rated KVA set point in the configuration menu may be set at an incorrect value. Appropriately set the Rated KVA set point in the configuration menu. * The Generator A phase PT input(s) may be improperly calibrated. Calibrate the Generator A phase PT input(s) of the generator set(s).
Why does my Woodward EGCP-2 sequence off more than one set when the system load is small enough?
If more than one set is sequenced off line when the system load is small enough to take additional sets off line, it may be because: * The REDUCED LOAD DELAY set point in the sequencing menu is too short. Increase the REDUCED LOAD DELAY set point in the sequencing menu. * The MAX STOP TIME set point in the sequencing menu is too short. Increase the MAX STOP TIME set point in the sequencing menu.
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.
What to do if the Woodward EGCP-2 synchronizer does not voltage match within spec?
If the synchronizer does not voltage match within specification, consider the following: * The Generator A phase PT and/or Bus A phase PT input(s) may be inadequately calibrated. Calibrate the Generator A phase PT and Bus A phase PT inputs. * The Voltage matching tolerance set point in the synchroscope menu may be too large. Appropriately set the Voltage matching tolerance set point in the synchroscope menu.
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.
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.
