Output and Overload Indicators
The Output indicator (green) will remain ON during normal operating
conditions.
If the generator is overloaded (see page
short in the connected appliance, the Output indicator (green) will go
OFF, the overload indicator (red) will go ON and current to the
connected appliance will be shut off.
Stop the engine if the Overload indicator (red) comes ON and
investigate the overload source.
The Overload indicator (red) also lights in the following cases:
When the inverter is overheated; the current to the connected
appliance will be shut off. Check to see if the air intake is obstructed.
Before connecting an appliance to the generator, check that it is in
good order, and that its electrical rating does not exceed that of the
generator. Then connect the power cord of the appliance, and start
the engine.
When an electric motor is started, both the Overload indicator (red)
and the Output indicator (green) may go on simultaneously. This is
normal if the Overload indicator (red) goes off after about five (5)
seconds. If the Overload indicator (red) stays on, consult your Honda
generator dealer.
