INTRODUCTION
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 fourteen 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 1 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 Honda GX690, 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.
