Engine Overspeed
This fault is indicated by fault code FC_6 and six blinks on
the LED indicator. This feature protects devices connected
to the transfer switch by shutting the generator down if
the engine happens to run faster than the preset limit. The
overspeed fault is detected as follows:
• If the generator output frequency is 65-70 Hz, after
three seconds, the generator will shut down.
• If the generator output frequency is greater than 70 Hz,
the generator will shut down immediately.
This condition is caused by a failed engine governor. To
remedy the problem, contact your installer or a local service
center.
Oil Temperature High
This fault is indicated by fault code FC_7 and seven blinks
on the LED indicator. The contacts of the temperature
switch ( A ) are normally open. The Oil Drain connector ( B ) is
shown for reference. If the engine oil temperature exceeds
approximately 148.9°C (300°F), the fault is detected and the
engine shuts down.
Common causes for this condition include running the
unit with all access doors removed, obstructed air inlet or
exhaust port, low oil level, or debris in the engine cylinder
cooling fins.
To resolve the problem, let the engine cool down and remove
any accumulated debris and obstructions. Ensure that the
access doors are installed whenever the unit is running.
Transfer Switch Fault
This fault is indicated by fault code FC_8 and eight blinks on
the LED indicator (if transfer switch is equipped with fault
detection).
To remedy the problem, contact your installer or a local
service center.
Generator Maintenance
The generator warranty does not cover items that have been
subjected to operator abuse or neglect. To receive full value
from the warranty, the operator must maintain the system as
instructed in the engine operator’s manual.
All adjustments should be made at least once each season.
Follow the requirements in the engine operator’s manual.
Generator maintenance consists of keeping the unit clean.
Operate the unit in an environment where it will not be
exposed to excessive dust, dirt, moisture or any corrosive
vapors. Cooling air louvers on the enclosure must not
become clogged with snow, leaves, or any other foreign
material.
Check the cleanliness of the unit frequently and clean when
dust, dirt, oil, moisture or other foreign substances are
visible on its exterior/interior surface.
NOTE : DO NOT use direct spray from a garden hose to clean
generator. Water can enter the engine and generator and
cause problems.
Engine Oil
The system is filled with synthetic oil (API SJ/CF 5W-30W).
This allows for system operation in the widest range of
temperature and climate conditions.
NOTE : The use of synthetic oil does not alter the required oil
change intervals described in the engine operator’s manual.
Changing Engine Oil
• Place the oil drain tube into an approved container.
• Push in and rotate the oil drain fitting 1/4 turn
counterclockwise. Slowly pull outward until oil starts
draining. DO NOT pull the oil drain fitting off the engine.
• When the oil has drained, push the oil drain fitting in
and rotate 1/4 turn clockwise until it locks in place.
• Slide the oil drain tube up into the clamp on the
generator.
