NOTE:
WESTERBEKE
recommends
that
the
following generator tests
and adjustments
be
peiformed
by
a qualified
technician.
DUAL
EXCITER
CIRCUIT
MODEL
These generators have dual Hertz and no-load voltage adjust-
ment connectors at each capacitor. There are five connectors
available for each capacitor. Two connectors
art:;
for Hertz
selection,
60
Hertz or
50
Hertz, and three connectors, #7, #8,
and #9,
ar~
for no-load voltage adjustment.
When making Hertz change
or
no-load voltage adjustments
proceed
as
follows:
1.
Shut the generator down.
i. Select the appropriate Hertz connection to plug into each
capacitor
#60, 60 Hertz, 1800 RPM or 50, #50 Hertz, 1500
RPM. The three other connectors at each capacitor, #7, #8,
and
#9,
will have an effect on the no-load voltage pro-
duced
by
the generator. One connector from each group
can be plugged into each capacitor. No-load voltage will
increase or decrease approximately
- 10
AC
volts
between connectors used
in
any
pc<"
combination
to
achieve the prescribed no-load
VOltiigr.

NOTE:
When
changing
Hertz produced
by
the
generator,
an
engine
speed adjustment at
the
throttle
ann
linkage
must
be
made.
The
AC output connections
on
the
terminal blocb
must
be
selected for
the
voltage and Hertz
to
be
p'roduced.
The
Hertz plug connection at
the
capacitor must
be
changed
for 50
Hertz
(#5) or
60
Hertz (#6).
The
frame ground
wire
must
be
moved
when
changing from 115
volts,
50 Hertz
to
230
volts,
50
Hertz.
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
telminals
with
an
insulated
(plastic
handle)
screwdriver.
This
will
discharge
any
excess
electricity.
Shore
Power
Connections
If
the installer connects shore power to the vessel's AC cir-
cuit, this must be done by means
of
the Shore Power Transfer
Switch.
Set the transfer switch shown in the diagrams
to
the
OFF position. This switch prevents simultaneous connection
of
shore power to generator output.
A
CAUTION:
Damage
to
the
generator
can
result
if
utility
shore
power
and
generator
power
are
connected
at
the
same
time.
This
type"of
generator
damage
is
not
covered
under
the
warranty;
it
is
the
installer's
responsi-
bility
to
make
sure
all
AC
connections
are
correct.
