ADJUSTMENT

1.

Remove

the

louvered metal

plate,

at

the

back of

the

generator,

covering

the

AC

terminal 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 governor

as

needed

to

obtain

the

correct engine speed before proceeding.

3. Refer

to

the

AC

load connections diagram for

the

correct

configuration then check the generator's no-load voltage

by

measuring the voltage

across

the

neutral

lead

an~

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

60Hz

Hertz

lead

is

plugged into

the

capacitor.

A

WARNING:

CapaCitors

must

be

discharged

before

handling

as

they

store

electricity

and

can

pack

a

poten-

tially

lethal

charge

even

when

disconnected

trom

their

power

source.

NOTE:

Simply

cross

the

capacitor's

two

terminals

with

an

insulated (plastic

handle)

screwdriver.

This

will

discharge

any

excess

electricity.

A

WARNING:

Make

certain

the

insulating

covers

on

the

unused

leads

are

in

place

and

are

NOT

in

contact

with

each

other

or

in

contact

with

the

generator's

housing.

A

WARNING:

00

not

attempt

to

make

a

no-load

voltage

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

adjustment

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

terminal

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 right

terminal,

or the voltage

needs

to

be

lowered

and

the lowest

num-

bered plug

is

connected, refer

to

the

WESTERBEKE
