GENERATOR

PHASE
NOTE:
WESTERBEKE
recommends
that
the
following generator
tests
and adjustments
be
peiformed
by
a qualified
technician.
SINGLE
EXCITER
NO-LOAD
VOLTAGE
ADJUSTMENT
1.
Remove
the louvered metal
plate,
at
the
back
of the
generator,
covering the
AC
tenninal connections
and
the
capacitor(s).
2.
Start the generator
and
allow
it
to
run
for
approximately
five
minutes
so
the engine
can
warm
up.
Make sure
the
generator
is
operating without
any
equipment
drawing
AC
current
from
the
generator (that
is,
shut off
all
electrical
appliances).
Make
sure the engine's speed
(Hertz)
is
correct.
Adjust
the
fuel
throttle/speed linkage
as
needed
to
obtain the correct engine speed before proceeding.
3.
Referring
to
the
AC
load connections diagram
below,
check
the
generator's no-load voltage
by
measuring
the
voltage
across
the neutral lead
and
the hot lead
with
a volt
meter.
Make sure
you
record
this
reading. The generator's
no-load voltage
is
115
-
124
volts
at
60.5
- 61.5
Hertz.
If
the
voltage output
is
higher or lower
than
specified,
proceed.

4.
Shut
off
the
generator.
Make
sure
the correct Hertz lead
(60
Hertz #6, or
50
Hertz
#5)
is
plugged into the
capacitor(s).
A
WARNING:
Capacitors
must
be
discharged
before
handling
as
they
store"
electricity
and
can
pack
a
poten-
tially
lethal
charge
even
when
disconnected
from
their
power
source.
NOTE:
Simply
cross
the
capacitor's
two
tenninals
with
an
insulated
(plastic
handle)
screwdriver.
This
will
discharge
any-excess
electricity.
A
WARNING:
Do
not
attempt
to
make
a
no-load
volt-
age
adjustment
while
the
generator
is
operating.
The
capacitor
can
produce
a
400-500
volt
charge.
Touching
any
wiring
can
produce
a
severe
electrical
shock.
In
addition,
attempting
to
make
a
no-load
voltage
adjust-
ment
while
the
generator
is
operating
could
cause
your
fingers
to
be
caught
in
the
generator's
rotor.
5.
There
are
three
plugs
grouped for the right capacitor
ter-
minal,
#7,
#8,
and
#9.
If
the
generator's no-load voltage
is
low,
then
disconnect
the
lower numbered plug
and
con-
nect
the
plug with the
next
higher
number.
If
the genera-
tor's
no-load
voltage
is
high,
then disconnect the higher
numbered
plug and connect the plug with
the
next
lower
number.
Note
that the
plug
presently connected
to
this
tenninal
may
be
anyone of ' the three plugs
available.
6 .. If the generator's no-load voltage cannot
be
adjusted
because the voltage
needs
to
be
increased
and
the
highest
numbered
plug
is
already
connected
to
the
tight terminal,
or
the
voltage
needs
to
be
lowered
and
the lowest
num-
bered
p1ug
is
connected, refer
to
the WES1ERBEKE Be
Genetator Troubleshooting Guide).
A
WARNING:
Make
certain
the
insulating
covers
on
the
unused
leads
are
in
place
and
are
NOT
in
contact
with
each
other
Dr
In
contact
with
the
generator's
housing.
