Generator Information and Theory
Output Indicator
When the generator is running normally and gener-
ating power, this indicator is lit green.
When using a device which requires a large starting
current, the overload warning light (red) and output
indicator (green) will temporarily light simultane-
ously. This operation is normal.
After the connected device has started up, the over-
load warning light (red) will turn off, while the output
indicator (green) will continue to be lit.
Oil Warning Lamp
As with all Yamaha generators, the engine will shut
off automatically when the oil level decreases to a
specified level.
When this happens and the recoil starter is pulled,
the engine will not start and the oil warning light will
turn on.
Control Panel
Refer to Section 3 for model specific control panel
diagrams.
Indicators
Overload Warning Lamp
During power generation, if a problem occurs with a
connected device, there is an overload, or the
inverter control unit overheats, the electronic breaker
will be activated and interrupt power output to pro-
tect the generator and/or connected devices.
■
When the electronic breaker operates:
The engine continues to run, but the control unit
stops output
The output indicator (green) turns off
The overload indicator (red) turns on
■
When the overload warning light turns on:
Stop the engine.
Verify the required load of the connected device,
and reduce to the rated load of the generator if
necessary. Verify whether or not there is a prob-
lem with a connected device. (A possible cause
of excessive current drain.)
Check for foreign matter in the cooling air inlet
and areas around the control unit which could
block incoming air.
■
To return the generator to normal output
operation:
Temporarily stopping the engine and re-starting
automatically resets the system to its original
state. (The system cannot be reset unless power
to the control unit is interrupted by stopping the
engine.)
