6 Troubleshooting
6.1 Avoiding Generator Set Shutdowns
By regularly performing the following periodic maintenance and guidelines, you will
greatly reduce the chances of a generator set shutdown:
Maintain an appropriate oil level.
Keep battery connections clean and tight.
Do not overload the generator set.
Keep the air inlet and outlet openings clear.
Refer to the Maintenance section for more information.
6.2 Control System
The generator set control system continuously monitors engine sensors for
abnormal conditions, such as low oil pressure and high coolant temperature. If any
of these conditions occur, the control will light a yellow Warning lamp or a red
Shutdown lamp and will display a message on the graphical display panel. In the
event of an engine shutdown fault (red Shutdown LED), the control will stop the
engine immediately.
