OVERLOAD INDICATOR LIGHT (red)

The overload indicator light (red) comes on when an
overload of a connected electrical device is detected,
the inverter control unit overheats, or the AC output
voltage rises. The electronic breaker will then activate,
stopping power generation in order to protect the gen-
erator and any connected electric devices. The AC
pilot light (green) will go off and the overload indicator
light (red) will stay on, but the engine will not stop run-
ning.
1 Overload indicator light (red)
When the overload indicator light comes on and power
generation stops, proceed as follows:
1. Turn off any connected electric devices and stop
the engine.
2. Reduce the total wattage of connected electric
devices within the application range.
3. Check for blockages in the cooling air inlet and
around the control unit. If any blockages are
found, remove them.
4. After checking, restart the engine.
TIP
9 The generator AC output automatically resets
when the engine is stopped and then restarted.
9 The overload indicator light may come on for a
few seconds at first when using electric devices
that require a large starting current, such as a
compressor or a submersible pump. However, this
is not a malfunction.
