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 neces-
sary 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 commer-
cial 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 elec-
tronic 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.

Additional optional A.T.S. sizes are available to meet
specific needs. Contact your local WINCO dealer, or the
WINCO Sales Department for a quote.
2) 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 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. 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. 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.
** NOTICE **
This unit will automatically transfer if a power outage
occurs while running in an exercise mode.
