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.

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,

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.
