CAM

TIMER

ADJUSTMENT

SECTION

Timers

are

available

with

7

‐

or

8

‐

cams.

The

cycle

times

are

not

adjustable.

The

cams

of

the

timer

are

wheels

whose

positions

are

either

fixed

or

adjustable.

Each

cam

controls

a

specific

machine

function,

as

noted

on

the

timer

decal.

Adjustable

cams

are

comprised

of

two

wheels

held

together

at

the

hub.

The

perimeter

of

each

wheel

is

divided

into

180

‐

degrees

of

high

cam

and

180

‐

degrees

of

low

cam.

When

one

of

these

wheels

is

rotated

on

the

hub

in

relation

to

the

opposing

wheel,

the

two

lower

cam

segments

can

form

a

notch

in

the

perimeter

(see

photo

below

right).

Above

each

cam

is

a

timer

switch

with

a

metal

finger

that

rides

along

the

outer

edge

of

the

cam.

When

the

finger

drops

into

the

lower

cam

notch,

the

function

of

that

cam

starts.

To

widen

the

notch

(length

=

time

energized)

or

close

the

notch

use

the

timer

adjustment

tool,

which

is

provided

and

taped

to

the

control

box

shelf.

This

tool

has

two

raised

buttons

that

fit

into

the

holes

on

the

side

of

each

wheel.

The

factory

sets

the

start

of

each

function

using

the

right

‐

side

wheel

of

the

cam.

TO

ADJUST

rotate

only

the

left

‐

side

cam

wheel.

The

left

‐

side

of

the

wheel

controls

the

point

when

that

specific

functions

ends.

Factory

settings

are

only

initial

settings,

adjustments

will

be

required

for

each

chemical

and

the

water

fill

time

because

water

pressures

will

be

different

for

every

account.

The

left

arrow

is

pointed

at

the

left

‐

side

wheel

of

the

cam

which

is

used

to

lengthen

or

shorten

the

low

cam

or

the

time

ON

for

the

respective

switch.

Center

high

‐

cam

&

low

‐

cam

notch.

Adjustable

cams

are

colored

either

black

or

gray.

Looking

at

the

front

of

the

cams

with

the

cam

timer

assembly

sitting

on

its

mounting

base

#1

Cam:

The

white

cam

on

the

left

is

the

master

cam.

It

controls

the

total

time

of

the

cycle

and

is

not

adjustable.

#2

Cam:

Continuing

left

to

right,

this

black

or

gray

cam

controls

detergent.

The

detergent

cam

is

adjustable

and

should

begin

as

soon

as

the

wash

action

starts.

#3

Cam:

This

white

cam

controls

the

drain

time

and

is

not

adjustable.

#4

Cam:

The

H2O

or

fill

cam

opens

the

water

solenoid.

Too

little

water

will

cause

the

pump

to

cavitate

(surging).

Overfilling

does

not

allow

the

soiled

wash

water

to

fully

drain

between

cycles,

causing

carry

over.
