Low Voltage
This fault isindicatedby three blinks.This condition is
causedby a restriction in the fuel flow, a broken or
disconnected signallead,a failed alternator winding, the
control panel circuit breaker isopen, or overloaded circuits
in the transfer switch.
Remedy the problem (you may need to contact your
installeror Briggsand Stratton TechnicalServicesfor
assistance),then reset the Fault Detection system, as
described above.
Engine FailTo Start
This fault isindicatedby four blinks.This feature prevents
the generator from damagingitselfifit continually attempts
to start in spite of another problem, such asno fuel supply.
Eachtime the system isdirected to start, the unit will
crank for 15seconds,pausefor 15 seconds,crank for
15 seconds,pausefor 15 seconds,and repeat. If the system
does not begin producing electricity after approximately
90 seconds,the unit will stop cranking and the LED will
blink.
The most likelycause of this problem isno fuel supply.
Check the insideand outside fuel shut off valvesto ensure
they are fully open. Other causescould be failed spark
plug(s),failed engine ignition,or the engine air filter is
clogged.Youmay need to contact your installerfor
assistanceifyou can't remedy these problems.When the
problem iscorrected, reset the Fault Detection system as
described above.
Low Frequency
This fault isindicatedby S blinks.This feature protects
devicesconnected to the transfer switch by shutting the
generator down if itsengine runs slower than the preset
limit.
This condition iscaused by a failed enginegovernor or by
excessiveloadson the transfer switch.To remedy the
problem, you may need to contact your installer or Briggs
and Stratton TechnicalServicesfor assistance.When the
problem iscorrected, reset the Fault Detection system as
described above.
Engine Overspeed
This fault isindicatedby 6 blinks.This feature protects
devices connected to the transfer switch by shutting the
generator down if itsengine happensto run faster than the
preset limitThe overspeed fault isdetected asfollows:
•If the generator output frequency runs at 72 Hz for five
seconds,the generator will shut down.
• If the generator output frequency reaches75 Hz,the
generator will shut clown instantly.
This condition iscaused by a failed engine governor.To
remedy the problem, you should contact your installer or
Briggsand Stratton TechnicalServicesfor assistance.When
the problem iscorrected, reset the Fault Detection system
as described above.
Oil Temperature High
Thisfault isindicatedby seven blinks.The contacts of the
temperature switch (Figure 5) are normally open. If the
engine temperature exceeds approximately 140°C (284°F),
the fault isdetected and the engine shuts down.
Common causesfor this condition include running the unit
with all accessdoors removed,obstructed air inlet or
exhaust port, or debris inthe engine cylinder cooling fins.
To resolve the problem, remove anyaccumulated debris
and obstructions and let the engine cool down. Ensurethat
the Oil Service door and/or the Control Paneldoor is
installed whenever the unit isrunning.When the problem is
corrected, reset the Fault Detection system asdescribed
above.
Power During Fault Condition
Whenever the Home Generator System isin an
uncorrected fault condition, the automatic transfer switch
is reset to UTILITY POWER.This meansthat when utility
power is restored, utility power will be applied to the
essential circuit loads.The generator is disconnected from
the automatic transfer switch for the duration of any
detected fault condition.
