CO Alarm Light(Red)
When the concentration of CO exceeds the standard, the CO alarm light will turn on Red and the generator
stops soon.
CO Failure Light(Yellow)
When the CO sensor is broken, the CO failure light will be on Yellow.
Oil Warning Light (Yellow)
The low oil level alarm system is designed to prevent engine damage due to insufficient oil in the crankcase.
The low oil level alarm system automatically shuts down the engine before the engine oil in the crankshaft
box is lowered to safety (the generator engine switch remains "ON").
NOTE: After the low oil level alarm system shuts down the engine, if you start the engine again, the low
oil alarm indicator (yellow) lights up and the engine cannot run. If this happens, please fill in the oil and
then restart the generator.
Overload Indicator (Red)
When the overload indicatoris on, it indicates that the generating set is overload and then the AC protector
works. It will stop the output of generating set to protect the electric equipment and the generating set itself.
At this time, the overload indicator (red) will be on, but the engine is still in running state. We should
disconnect the electrical equipment first.
If the overload indicator (red) is extinguished and the operation indication (green) is on, reconnect the
electrical equipment, otherwise shut down the engine and check for malfunction.
Running Indicator (Green)
The output indicator lights up when generating set starts and has normal output.
Reset Button
The reset button is used to restore output if an overload occurs. To restore output, reduce the loads and
press the rest button.
Grounding Terminal
The grounding terminal is designed to prevent electric shock by connecting it to the grounding wire. The
