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 conditions specified
by the manufacturer of the applicable engines.
INTRODUCTION AND
DESCRIPTION
The package standby system includes all items necessary
for a completely automatic standby power system as
standard equipment.
DESCRIPTION
This packaged standby system is designed to automati-
cally 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 electrical power and the Automatic
Transfer Switch (A.T.S.) 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 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 of two major
components:
1) AUTOMATIC TRANSFER SWITCH
A wall mounted Automatic Transfer Switch (A.T.S.)
designed for inside installation. A fourteen day electronic
exerciser clock is installed in the A.T.S. as standard
equipment. The A.T.S. also contains the power failure
sensing circuitry necessary to send a start/stop signal to
the engine generator set.

2) ENGINE/GENERATOR
The engine generator set consists of a Briggs & Stratton,
twin cylinder, four cycle air cooled engine. The engine is
factory equipped to run on L.P. or N.G. fuel. The engine
operates at 3600 rpm and frequency regulation is main-
tained 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 500 CCA (BCI group
26) 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 10
second start delay, 90 second cool down delay and cycle
cranking.
COLD WEATHER OPERATION
Extreme cold weather operation requires special
considerations. Higher CCA batteries are required for
cold weather starting, 650 CCA or larger are recom-
mended. In addition you should consider installing an
oil heater kit and a battery warmer for reliable starting
during cold weather.
** NOTICE **
This unit will automatically transfer if a power outage
occurs while running in an exercise mode.
