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 automatically 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:

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 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. Voltage regulation is provided by an
external voltage regulator mount on the generator,
variation is +/- .5% steady state.. The generator is
connected to the engine’s tapered (quill) crankshaft
extension. The engine generator is mounted in a NEMA
3R 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 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.
1) AUTOMATIC TRANSFER SWITCH
A wall mounted Automatic Transfer Switch
(A.T.S.) designed for inside installation. The NON-UL
A.T.S. consists of a line side contactor and a generator
side contactor. The contactors are both electrically and
mechanically interlocked. A seven 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.
