Action Description/ Comments
Shutdown The ECM shut down the engine and
reported an unknown fault code.
Warning DC power to the controller has been
interrupted and the date and time may
not be correct. Event history may not
have accurate time/date stamps.
Shutdown The controller shutdown the generator
because engine compartment air
temperature has exceeded 174_F
(79_C).
Warning The controller has detected engine
compartment temperature that is above
167_F (75_C).
Shutdown The controller shutdown the engine
because the coolant level sensor
indicated low coolant for 5 seconds or
more.
Shutdown The ECM shutdown the engine and
reported high coolant temperature as
the fault.
Warning The ECM is reporting high coolant
temperature.
Warning The ECM is reporting low coolant
temperature.
Shutdown The ECM shutdown the engine and
reported no coolant temperature signal
as the fault.
Warning The controller has been loaded with
default parameters.
Shutdown The controller shut down the generator
because there is a conflict in
addressing on the ECM CAN bus.
Shutdown The controller shut down the generator
because communication with the ECM
was lost, for 4 or more seconds.
Shutdown The controller shut down the generator
because the ECM does not match any
of the supported models.
Shutdown The controller shut down the generator
because the emergency stop circuit
was tripped (open circuit).
Shutdown The controller shut down the generator
because engine speed, as calculated
from AC frequency, was above the high
speed setting for 0.3 seconds or more;
or the ECM shut down the engine and
reported overspeed as the fault code.
Check
Troubleshoot engine
operation per the engine
service manual.
Verify the time and date
settings to ensure proper
operation of scheduled
operations and for event
history logging.
Troubleshoot fan circuit failure
and/or temperature sensor
circuit. Check for blockage of
intake or exhaust vents.
Troubleshoot fan circuit failure
and/or temperature sensor
circuit. Check for blockage of
intake or exhaust vents.
Check coolant level and fill as
needed.
Check for air in cooling
system.
Check the coolant level
sensor operation.
Check engine cooling system.
Check radiator fans for proper
operation. Check for
blockage of inlet and exhaust
vents.
Check engine cooling system.
Check radiator fans for proper
operation. Check for
blockage of inlet and exhaust
vents.
Check cooling system.
Check cooling system and
coolant level sensor circuit.
Configure settings as needed
or as required for desired
operation.
Verify no other devices
connected and broadcasting
on the CAN bus.
Check CAN communication
wiring between controller and
ECM.
Verify controller configuration
using SiteTech. Consult local
service technician.
Check E-stop circuit for open
switches, broken wires,
disconnected wires, etc.
Troubleshoot engine
operation per the engine
service manual.
