INTRODUCTION
TESTING POLICY
Before any generator is shipped from the factory, it is fully
checked for performance. The generator is loaded, and the
voltage, current, and frequency are carefully checked.
Rated output of generator 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 tractor manufacturer.
The WINCO power take-off generators are designed
primarily for farm use as a standby electrical power supply,
utilizing the power take-off of a tractor or truck as the prime
mover. This PTO drive generator will provide, 120/240V
1-PH, 120/208V 3-PH, 120/240V 3-PH, 277/480V 3-PH, or
346/600V (depending on model), 60Hz electrical service
when properly driven.
DO NOT operate and/or store the unit outside during
inclement weather without adequate protection from the
elements. Failure to do so will damage the unit.
It is acceptable to use this generator with a tractor with
less HP output than required for full power operation. The
generator will work but produce only as much kW output
as the tractor can supply HP for. For example, a 20 HP
output tractor will deliver a maximum of approximately 10
kw.
If you are using a tractor with more HP than required to
run the generator care should be taken to ensure that you
do not overload the generator causing overheating and
equipment damage. Observe input RPM specifications.
The generator may be foundation mounted for use as
standby power source, or trailer mounted, and used
as portable electrical power sources for areas where
commercial power is not readily available, such as out
buildings.
This generator includes a frequency meter to warn against
high or low frequency, three output power receptacles,
an overload protection circuit, and an electronic excitation
circuit. To reduce maintenance problems, the coupling
between the generator input shaft and rotor consists of
precision helical gearing rather than a chain link drive. The
input shaft is a 1 3/8in. 6-spline.
IMPORTANT: THE MANUFACTURER STRONGLY
RECOMMENDS RUNNING THE GENERATOR UNDER LOAD
AT LEAST ONCE A MONTH IN ORDER TO EVAPORATE
ANY ACCUMULATED MOISTURE CONDENSATION.
