direct drive, rotating armature design. The generator is
connected to the engine flywheel via a flexible drive disk.
The engine generator is mounted in a water tight
enclosure for outside installation. Connection boxes are
provided for all customer connections (both AC output
and DC control). A customer supplied 500 CCA (BCI
group 24) battery is required to complete the installation.
Engine operation is controlled by an Electronic Engine
Control Module (E.C.M.) mounted in the engine generator
enclosure. The E.C.M. is equipped standard with a 3
second start delay, 3 minute cool down delay and cycle
cranking consisting of five, 12 second on/12 second off
cycles. The ECM has both oil pressure and high water
temperature delays build into the starting circuit. During
initial start up the oil pressure delay is 12 seconds, to
allow the engine time to build oil pressure, before a
shutdown will occur. The high water temperature
shutdown has a 60 to 90 second lockout, allowing the
engine time to clear the hot water out of the block in case
of a hot restart. In addition if the generator should loss
output during a run cycle the engine will continue to run
for about 60 seconds and then shutdown and display
and overcrank light, the starter will not reengage during
this time or until the generator selector switch has been
cycled off and back on. This is the only way to clear a
fault light.
** NOTICE **
This unit will automatically transfer if a power outage
occurs while running in an exercise mode.

ENGINE SPECIFICATIONS:
Refer to engine operating and maintenance instruc-
tions.
** NOTICE **
Regarding Engines - This manual covers the generator
portion of these units. See the separate engine instruc-
tion manual for engine-related problems, detailed engine
information and engine warranty.
** CAUTION **
Be sure to check the engine oil level frequently, as
specified in the engine manual.
The engine manufacturer has established an excellent
worldwide engine service organization; engine service is
available from a nearby authorized dealer or distributor;
check the yellow pages of the telephone directory under
“engines,” or ask the dealer from whom you purchased
the power plant.
The rated power of each engine-generator is limited by
the temperature, altitude and all other ambient conditions
specified by the engine manufacturer. Engine power will
decrease 3-1/2% for each 1000 ft. above sea level, and
will decrease an additional 1% for each 10 degrees
Fahrenheit above 60 degrees Fahrenheit.
UNPACKING INSTRUCTIONS
** NOTICE **
When unpacking the generator set, be sure to inspect it
carefully for freight loss or damage. If loss or damage is
noted at the time of delivery, require that the person
making the delivery make note of the loss or damage on
the freight bill, or affix his signature under the consignor’s
memo of the loss or damage. Contact the carrier for
claim procedures.
When loss or damage is noted after delivery, segregate
the damaged material, and contact the carrier for claim
procedures. Be sure to retain the packaging material for
carrier inspection.
“Concealed Damage” is understood to mean damage
to the contents of a package which is not in evident at the
time of delivery by the carrier, but which is discovered
later. The carrier or carriers are responsible for mer-
chandise lost or damaged in transit. The title to goods
rests with the consignee when generators are shipped
F.O.B. factory, and only the consignee can legally file a
claim.
