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.

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 com-

pressor or a submergible pump. However, this is

not a malfunction.

9 For EF3000iSEB, the overload indicator light 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 is flashing, elec-

tric devices that require a large starting current

cannot be started.
