e. Always avoid hot mufflers, exhaust manifolds,
and engine parts. They can cause severe
burns instantly.
f. Installing a generator set is not a “Do-it-your-
self” project. Consult a qualified, licensed elec-
trician or contractor. The installation must com-
ply with all national, state, and local codes.
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 generators is based on engineering
tests of typical units, and is subject to, and limited
by, the temperature, altitude, fuel, and other condi-
tions specified by the manufacturer of the applicable
engines.
INTRODUCTION AND
DESCRIPTION
The package standby system includes all times
necessary for a completely automatic standby power
system as standard equipment.
DESCRIPTION
The package standby system is designed to au-
tomatically provide standby power to unattended
loads during electrical outages. Upon an interruption
of normal electrical service the packaged standby
system electrical control circuits will automatically
start the engine. The generator will produce electri-
cal power and the Automatic Transfer Switch (ATS)
will automatically transfer the electrical loads to the
generator set. Upon restoration of normal electri-
cal service the emergency transfer switch will sense
return of the normal commercial power. The Auto-
matic Transfer Switch will retransfer 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.
These packaged standby systems consist ot two
major components:
1) AUTOMATIC TRANSFER SWITCH
A wall mounted ASCO 65 Automatic Transfer
Switch (ATS) designed for inside installation. The
transfer switch is UL008 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 5 second transfer delay to allow the engine
to warm up before transferring the load to the gen-
erator. When the line power is restored the ATS has
a 5 minute retransfer delay to allow the incoming util-
ity to stabilize before transferring back to line power
and then an additional  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.

2) ENGINE / GENERATOR
The engine generator set consists of a Honda, twin
cylinder, four cycle air cooled engine. The engine is
factory equipped to run on LP or NG fuel. The en-
gine 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
connnected to the engine’s tapered (quill) crankshaft
extension. The engine generator is mounted in a
drip-proof enclosure for outside installation. Con-
nection boxes and terminal blocks are provided for
all customer connections (both AC output and DC
control). A customer supplied 2 volt 500 CCA (BCI
group 26) battery is required to complete the instal-
lation.
** NOTICE **
This unit will automatically transfer if a power outage
occurs while running in an exercise mode.
