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 submergible pump. However, this

is not a malfunction.

ing current, such as a compressor or a submergible

pump.
