System Shutdown Fault Lamp. Red lamp indicates that the generator set has shut down because of a fault condition. The unit
will not start without resetting the controller, see the section titled: Controller Resetting procedure.
See the section titled: System Fault Shutdown Lamp with Digital Displays, for definitions of the items listed. The following
conditions cause a system shutdown:
• AC sensing loss
• Alternator protection
• Auxiliary input (analog or digital)
• Common fault
• ECM address conflict
• ECM communications loss
• ECM diagnostics (multiple engine inputs)
• ECM model mismatch
• Emergency stop
• Enclosure temperature: high shutdown (available on select Telecom units only)
• Engine over speed
• Engine under speed
• File system error (controller firmware fault)
• Fuel tank leak (diesel-powered models only)*
• High coolant temperature
• Internal failure
• kW overload
• Locked rotor (failed to crank)
• Loss of fuel
• Low coolant level*
• Low engine oil level*
• Low fuel level (diesel-powered models only) *
• Low oil pressure
• Megajector communications loss
