Fault Shutdowns
Code Description
Hi CO: Carbon monoxide
sensor presence from
(fault) sensor.
Shutdown occurs
because of the
presence of CO.
Hi CO: Carbon monoxide
engine fault from ECM.
(fault) Shutdown occurs
because of the
presence of CO or
deteriorating
emission-control
components (such
as the catalyst).
No CO Carbon monoxide
sensor sensor missing
(fault) shutdown occurs
if communication
is lost between
the CO sensor
and the ADC.
Over voltage Overvoltage
(fault) shutdown occurs if
the voltage
exceeds the
default setting of
the voltage
regulator setpoint.
Under volt Undervoltage
(fault) shutdown occurs
if the voltage falls
below the default
setting of the
voltage regulator
setpoint.
Over freq Overfrequency
(fault) shutdown occurs
when the
governed
frequency exceeds
the default setting
of the system's
frequency setpoint.
Under freq Underfrequency
(fault) shutdown occurs
when the governed
frequency falls
below the default
setting of the
system's frequency
setpoint .

Immediate service required.
Contact an authorized
distributor/dealer for service.
Ensure windows are open for proper
ventilation.
Operate the blower to expel
dangerous fumes.
Move the vessel away from other
vessels (as another vessel may be the
source for the presence of the CO).
Check the generator exhaust system
(see Section 3.6).
