The generator set shuts down automatically under the
following fault conditions and cannot be restarted until
the fault condition is corrected. The system automatically
resets when the problem is corrected or the generator
set cools (if high engine temperature was the fault).
Fault Description
High engine
temperature
Shutdown occurs 5 seconds after
the fault. The high engine
temperature shutdown does not
function during the first 5 seconds
after startup.
NOTE: The high temperature
shutdown functions only when the
coolant level is in the operating
range.
High exhaust
temperature
Shutdown occurs 5 seconds after
the fault. The high exhaust
temperature shutdown does not
function during the first 5 seconds
after startup.
