How to start Woodward Control Unit engine when it doesn't start with the "Start" button?
If the engine doesn't start when you press the Start button, it might be because the unit is in Stop mode, indicated by the Stop LED being lit. To resolve this, press the Operating Mode button twice to switch to manual mode.
How to troubleshoot a Woodward easYgen-300 that does not power up?
If your Woodward Control Panel unit isn't powering up, it could be due to the power supply being outside the operating range or the power supply polarity being reversed. To check, with the power supply voltage connected to terminals 1(-) and 2(+) of the easYgen-300, measure the voltage at these terminals.
What causes alarm 13A Generator undervoltage on Woodward easYgen-300?
If the "13A - Generator undervoltage" alarm appears after the engine has fired on your Woodward Control Panel, the generator voltages may not be properly connected to the easYgen-300, or the wrong wiring might be selected for the generator voltage measurement. Check the generator voltages after the engine starts. Also, use the LeoPC1 configuration software to check the settings for the "Generator voltage measuring" parameter.
Why is mains circuit breaker closed LED not lit on Woodward easYgen-300 Control Panel?
If the "Mains Circuit Breaker Closed" LED is not lit even though the circuit breaker is closed on your Woodward Control Panel, it could be due to a miswired "Mains Circuit Breaker Closed" signal or an incorrect setting of the "Ignore Breaker Replies" parameter. Measure the voltage between terminals 19 and 15 on the easYgen-300. Also, use the Woodward "LeoPC1" configuration software to check the setting of the "Ignore Breaker Replies" parameter.
How to fix generator circuit breaker closed LED not lit on Woodward Control Panel?
If the "Generator Circuit Breaker Closed" LED isn't lit even when the circuit breaker is closed on your Woodward Control Panel, the "Generator Circuit Breaker Closed" signal could be miswired, or the "Ignore Breaker Replies" parameter might be set incorrectly. Measure the voltage between terminals 20 and 15 on the easYgen-300. Also, use the Woodward "LeoPC1" configuration software to check the setting of the "Ignore Breaker Replies" parameter.
Why does alarm 21A Underspeed occur on Woodward easYgen-300 after engine has fired?
If the "21A - Underspeed" alarm appears after the engine has fired on your Woodward Control Panel, it might be caused by a miswired or defective pickup sensor, or the engine has stalled. Verify that the pickup sensor is properly wired to terminals 37 (GND) and 38(+) on the easYgen-300, check the pickup sensor for proper functionality, and troubleshoot the engine fuel and air supply.
What to do if alarm 61A Coolant temperature occurs after engine has fired on Woodward Control Panel?
If the "61A – Coolant temperature" alarm appears after the engine has fired on your Woodward Control Panel, it could be due to the engine temperature being too high, the coolant temperature sensor being miswired, or the sensor being defective. Check the engine temperature, the wiring of the temperature sensor, and the coolant temperature sensor itself.
Why does alarm 60A oil pressure occur on Woodward easYgen-300 after engine has fired?
If the "60A - Oil pressure" alarm appears after the engine starts on your Woodward Control Panel, the engine may not be producing oil pressure, the oil pressure sensor could be miswired or defective. You should check the engine oil pressure, the wiring of the oil pressure sensor, and the oil pressure sensor itself.
What to do if the engine does not start by setting the remote-start signal on Woodward Control Panel?
If the engine doesn't start using the "Remote-Start" signal on your Woodward Control Panel, the unit might be in "Stop" or "Manual" mode. Press the "Operating Mode" button to select "Auto" mode. Also, check the voltage between terminals 18/15 to ensure the "Remote-Start" signal is correctly wired to the easYgen-300.
Why does alarm 30A start fail occur on Woodward easYgen-300 Control Panel?
If alarm "30A - Start fail" occurs on your Woodward Control Panel, possible causes include a low fuel situation, a disconnected fuel line, a defective or miswired fuel relay output, a defective or miswired crank relay output, or a crank cutout speed parameter set too low. To troubleshoot, check if enough fuel is present, ensure the fuel line is properly connected, measure the resistance between terminals 13 and 11 (fuel relay) and 14 and 11 (crank relay) on the easYgen-300, and measure engine speed when cranking before ignition.
