Oil-warning indicator light (red)
When the oil in crankcase reduces to less than
safety line, the oil protection system will automatically
turn off the engine and the oil-warning indicator light
will be on; fill oil up to oil level, the engine will re-start.
Tip: when the engine flames out or cannot be started,
screw the rotary knob of power switch to “ON” position,
then pull the starting handle.
When the oil warning indicator light flashes for
several seconds, it means the oil volume is insufficient,
fill oil to make it re-start.
Check the indicator light with ohmmeter and
confirm its conductivity. Replace the indicator light if
the resistance is infinite.
Overload indicator light (red)
When the overload indicator light is on, the
generator can detect that the output of its connecting
electrical equipment has been overload, which will
cause inverter overheating or AC voltage increase. At
this time, AC protector operates, to stop the generation
of the generator so as to protect the generator and its
electrical equipment. AC indicator light (green) will be
off while the overload indicator light (red) will be on;
however, the engine will not stop operation.
When the overload indicator light is on and
generator unit has no output, please take following
countermeasures:
1. Shut down all connecting electrical equipment and
stop the engine.
2. Reduce the total power of connecting electrical
equipment to the range of rated output.
3. Check if the inlet of cool air is blocked with foreign
matters and whether related control parts are normal. If
yes, eliminate the problems immediately.
4. Re-start the engine after check.
Tip: when using the electrical equipment with
relatively high starting current (such as compressor and
submersible pump), the overload indicator light may be
on for several seconds at the beginning, but this is not
the fault aforesaid.
Check the indicator light with ohmmeter and
confirm its conductivity. Replace the indicator light if
the resistance is infinite.
