AE00788 Overload indicator light q The overload indicator light 1 comes on when an over- load 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 760-029 power generation in order to protect the generator 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. 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. 4. After checking, restart the engine. NOTE: 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 submergible pump. However, this is not a malfunction. - 16 -

Overload indicator light
The overload indicator light
1
comes on when an over-
load 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 generator 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.
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.
4.
After checking, restart the engine.
NOTE:
9
The generator AC output automatically resets
when the engine is stopped and then restarted.

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 com-
pressor or a submergible pump. However, this is
not a malfunction.
