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 running.

Overload indicator light (red)
When the overload indicator light (red) 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 rated output.
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.

The generator AC output automatically resets
when the engine is stopped and then restarted.

The overload indicator light (red) may come on for
a few seconds at first when using electric devices
that require a large starting current, such as a com-
pressor or a submersible pump. However, this is
not a malfunction.

For EF3000iSEB, the overload indicator light (red)
may flash when using electric devices that require
a large starting current. However, this is not a mal-
function. (The flashing indicator is a result of the
generator temporarily discharging more than its
rated wattage.)
While the overload indicator light (red) is flashing,
electric devices that require a large starting current
cannot be started.
