Hi CO:
sensor
(fault)
Carbon monoxide
presence from
sensor.
Shutdown occurs
because of the
presence of CO.
Pulsed signal 20 Hz 0 sec 10 sec N/A 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).
Hi CO:
engine
(fault)
Carbon monoxide
fault from ECM.
Shutdown occurs
because of the
presence of CO or
deteriorating
emission-control
components (such
as the catalyst).
ECM data Control limit 0 sec 15 sec N/A 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).
No CO
sensor
(fault)
Carbon monoxide
sensor missing
shutdown occurs
if communication
is lost between
the CO sensor
and the ADC.
Pulsed signal No signal 0 sec 10 sec N/A Check the connections to the CO
sensor. If connections are okay,
replace the CO sensor.
Contact an authorized
distributor/dealer for service.
Over voltage
(fault)
Overvoltage
shutdown occurs if
the voltage
exceeds the
default setting of
the voltage
regulator setpoint.

nominal
Contact an authorized
distributor/dealer for service if
problem continues.
Under volt
(fault)
Undervoltage
shutdown occurs
if the voltage falls
below the default
setting of the
voltage regulator
setpoint.

Reduce the load and restart the
generator set.
Check the F5 fuse.
Contact an authorized
distributor/dealer for service if
problem continues.

shutdown occurs
when the
governed
frequency exceeds
the default setting
of the system’s
frequency setpoint.
Alternator
output

shutdown occurs
when the governed
frequency falls
below the default
setting of the
system’s frequency
setpoint .
Alternator
output
