NOTE:
WESTERBEKE recommends that the following generator tests
and adjustments be performed by a qualified technician.
DESCRIPTION
The
Be
generator is a brushless; .... self~exciting generator which
requires
only
the drive force of the engine to produce an AC
output. The stator houses two sets of windings; the main stator
windings and the exciter windings. When the generator is
started, residual magnetism in the four rotating poles induces a
voltage in the stator windings which then generates an even
larger voltage in the exciter windings. This mutual buildup of
voltage in the four rotating poles and in the exciter windings
quickly reaches the saturation point of the capacitor(s) and a
regulated energy field is then maintained in the stator. At the
same time, this regulated field produces a steady AC voltage in
the stator windings which can then be drawn off the generator's
AC tenninalsto operate AC equipment.
The generator is a single phase, 120 volt AC two wire at 60 Hertz.
A liS volt AC two wire or 230 volt two wire at 50 Hertz. Refer to
the SPECIFICATIONS section of this manual for generator ratings.
The generator data plate gives the voltage, current and frequency
ratings of the generator. An AC wiring decal is affixed to the
inside of the louvered cover at the generator end. Diagrams of the
v.Ji.ous AC voltage connections are provided on this decal as well
as in this manual.

Circuit Breaker
A circuit breaker is installed on all single phase
WESTERBEKE generators. This circuit breaker will
automatically disconnect generator power in case of an
electrical overload. The circuit breaker can be manually shut
off when servicing the generalDr
to
ensure that no power is
coming into the boat.
NOTE:
This circuit breaker is available as a WESTERBEKE
add-on kit for earlier model generators; contact your
WESTERBEKE dealer.
