INTRODUCTION
TESTING POLICY
Before any generator is shipped from the factory, it is fully
checked for performance. The generator is loaded to its
full capacity, and the voltage, current, and frequency are
carefully checked.
Rated output of generator is based on engineering tests
of typical units, and is subject to, and limited by, the
temperature, altitude, fuel, and other conditions specified
by the manufacturer of applicable engines.
PRODUCT DESCRIPTION
The package standby system is designed to automatically
provide standby power to unattended loads during
electrical outages. Upon interruption of normal electrical
service, the packaged standby system electrical control
circuits will automatically start the engine. The generator
will produce electrical power and the Automatic Transfer
Switch (ATS) will automatically transfer the electrical loads
to the engine-generator set. Upon restoration of normal
electrical service the emergency transfer switch will sense
return of the normal commercial power. The Automatic
Transfer Switch will transfer the load back to the normal
commercial power source. The engine control circuits will
begin a cool-down cycle, after which the fuel supply will be
shut off and the engine ignition system disabled.
AUTOMATIC TRANSFER SWITCH (not included)
A wall mounted ASCO 185 Automatic Transfer Switch (ATS)
designed for inside or outside installation is recommended.
The transfer switch is UL1008 approved. A seven day
electronic exerciser circuit is installed in the ATS as standard
equipment. The ATS also contains the power failure sensing
circuitry necessary to start and stop the engine generator
set. The transfer switch is also equipped standard with a 3
second start delay, and a 15 second transfer delay to allow
the engine to warm up before transferring the load to the
generator. When the line power is restored the ATS has
a 5 minute transfer delay to allow the incoming utility to
stabilize before transferring back to line power and then
an additional 2 minute engine cool down delay before the
engine shuts down. Read and understand the ATS owners
manual before installing, servicing or operating the transfer
switch.

ENGINE / GENERATOR
The engine generator set consists of a Briggs & Stratton
Vanguard, twin cylinder, four cycle air cooled engine. The
engine is factory equipped to run on LP or NG fuel. The
engine operates at 3600 rpm and frequency regulation
is maintained by the engine governor within 4 cycles
variation (62.5 Hz - 58.5 Hz) from no load to rated load. The
generator is a brushless, single bearing, direct drive, rotating
field design. The generator is connected to the engine’s
tapered (quill) crankshaft extension. The engine generator
is mounted in a drip-proof enclosure for outside installation.
Connection boxes and terminal blocks are provided for all
customer connections (both AC output and DC control). A
customer supplied 12 volt 500 CCA (BCI group 26) battery
is required to complete the installation.
NOTICE
This unit will automatically transfer if a power outage occurs
while running in an exercise mode.
