If your Doosan Inverter indicates an Over Speed error, it means the engine RPM is exceeding the configured over speed values. First, check the speed setting. If the issue persists, adjust the PID setting values.
How to fix Actuator Current Open error on Doosan G135XW/XF?
An Actuator Current Open error on your Doosan Inverter suggests a disconnection in the actuator or its connecting circuits. Inspect the actuator and connecting circuits for any disconnections. If you still encounter the problem, consider replacing the actuator.
What causes Actuator Current Short on Doosan Inverter and how to resolve it?
An Actuator Current Short error on a Doosan Inverter typically indicates short-circuits in the actuator or connecting circuits. Check the actuator and connecting circuits for any short-circuits. If the problem persists, replace the actuator.
Why does my Doosan G135XW/XF Inverter show a Pick-up Error during engine operation?
A Pick-up Error during engine operation (Engine RPM 600 or higher) with your Doosan Inverter suggests problems in the sensor signals. Check the RPM sensor and its connecting circuits. If the issue continues, consider replacing the RPM sensor.
How to troubleshoot Pick-up Error on Doosan G135XW/XF when starting engine?
A Pick-up Error during engine start (Engine RPM lower than 600) on your Doosan Inverter indicates issues with sensor signals. You should check the RPM sensor and its connecting circuits. If the problem persists, replace the RPM sensor.
What does FET Drive Error mean on a Doosan G135XW/XF Inverter?
A FET Drive Error on your Doosan Inverter suggests damages to components in the actuator output section inside the controller. Check the actuator and connecting circuits. If the error continues, replace the controller.
What to do if Doosan G135XW/XF Inverter displays Battery Low?
If your Doosan Inverter displays a 'Battery Low' message, you should check the battery line. If the problem persists, replace the battery.
What to do if Doosan G135XW/XF Inverter displays Battery High?
If your Doosan Inverter displays a 'Battery High' message, you should check the battery line. If the problem persists, replace the battery.
Why is the winding temperature raised in my Doosan Portable Generator?
High winding and air cooling temperatures in your Doosan Portable Generator can stem from several factors. High ambient temperature can be a cause, so ensure adequate ventilation to reduce it. Hot air reflow can also be a factor; provide sufficient free space around the generator. Remove any nearby heat sources. Inspect the cooling system for defects and ensure correct assembly. Clear any obstructions from air loopholes and clean or replace a very dirty air filter. Ensure adequate airflow by removing obstacles. Check the engine speed (RPM/frequency). Inspect the thermodetectors. Overloads can cause this issue, so eliminate any overload and allow the generator to cool before restarting. Verify that the load's power factor (cosfì) is at least 0.8, or reduce the load.
What to do if the voltage is lower than rated on my Doosan Portable Generator?
If your Doosan Portable Generator's output voltage is lower than rated (between 50% and 70%), check the following: Ensure the engine speed (RPM/frequency) is at the rated level. Adjust the voltage potentiometer until the voltage reaches the rated value. Replace any blown fuses with spares. If the issue persists, the regulator might be faulty; disconnect and replace the AVR. Also, check for overexcitation limitation intervention and reset the potentiometer for excitation limitation (AMP).
