TIMER for MODEL 24

DISHWASHERS

General Description

The timer is a self-contained (frame mounted) timer of the repeating cycle type. It is mounted on
the control panel of Jackson Automatic Dishwashing Machines, to control the automatic
functions of these-machines. It consists of a dock motor which operates on 60 cycle, AC,
110VAC or 50 cycle, AC, 220VAC. In addition to the dock motor, the timer also contains a driven
cam arrangement which operates three micro switches.

Principle of Operation:

The timer controls various operations of the automatic washers as per wiring diagram for each
machine; however, the timing cycle and the micro switches are the same for each model. The
time for One Complete Revolution of the cam shaft Is approximately 300 seconds, allowing two
wash and two rinse operations for each complete revolution of the cam shaft. The micro switch
nearest the timer motor is the hold circuit and uses both the NO and NC contacts. The middle
micro switch controls the wash and uses the NO contact. The micro switch farthest away from
the timer motor controls the rinse and uses just the NC contact

Service Instructions:
Caution: Always remove the power to the machine before working on the control panel or while

servicing the components on the switch panel. All electrical checks should be made by
qualified personnel.

Timer operation can be observed after removing the machine's kickplate by loosening the two
screws holding it.

If It is determined that the timer Is defective. It is recommended that a new timer be installed. If a
new timer is not available, limited field maintenance can be accomplished by changing the micro
switch.

A frozen contact on a micro switch will be indicated If one function of the timer Is being executed
all the time or If there Is an absence of a click when the switch arm is actuated.

To Replace Micro Switch:

1. Remove all wires from the timer, properly tag them to assure proper replacement.

2. Remove the two screws which hold the timer to the control panel.

3. One screw holds the micro switches, cams and actuating arms In the frame. This screw
is seen on the side opposite the motor. Remove this screw.

Note: Be sure to note which cam goes with which micro switch. Cam nearest timer motor has

½ of Its edge raised; center cam has 2 large depressed areas; cam furthest from timer
motor has two smaller depressed areas.

4. The unit can now be taken apart and the defective micro switch replaced.

5. Reassemble.
Note: The flanges on the cams are such that they only mesh in one direction.

The timer's cam drive system is equipped with a clutch to enable one to view the operations of
the cams and micro switches. Remove power to machine before touching timer. Rotate cams by
turning with fingers; cams will turn in one direction only. Do not force them. As cams actuate
switches, listen for the "click"" of the switch or test the switches with an ohmmeter.

DEFECTIVE TIMER MOTOR

TIMER

A defective motor is indicated by the fact that the cams do not rotate or the machine does not
perform the automatic operations, or performs a specific part of the cycle conti nuously, but
works okay on manual. Remember, the timer motor is controlled by the start switch and the hold
micro switch; check this complete circuit before changing motor.

To Replace Motor:

1. Remove motor loads from shorting bar and neutral.

2. Remove the two screws which hold the motor.

3. Replace with a new motor.

Note: It may be necessary to remove complete timer to replace motor; If so, foilow steps 1 and

2, previous page.

This light comes on only when automatic cycle is in progress and extinguishes

when cycle is complete. It is located In the start switch.

This switch is used to by-pass the timer and operate the wash pump manually.
The wash pump will run as long as this switch is "on". The prime purpose of this
switch is to extend the wash period for extremely soiled dishes before putting
them through the normal automatic cycle. It may also be used as an emergency
back-up should the timer ever fall to operate. The required wash time is Indicated

on the control panel (front).

This switch is spring-loaded and must be held in its up position to operate. When
switch is operated, water Is allowed to fill mach
be used as an emergency back-up in case of timer failure for rinsing dishes. The

required rinse time is Indicated on the front control panel.

This switch applies power to the heat circuits which are composed of automatic

control devices that turn heaters on and off to maintain required temperatures.

This indicating light remains lit all the time the heat switch is on. It is located in

the heat switch.

This switch controls the manual draining of the unit at the end of a meal period or
at the end of the day. It is a spring-loaded switch and must be held in its up

the motor to go Into reverse, pumping the water out of the sump into the drain

line. This switch should be held for approximately 50 seconds.

REPLACEMENT of SWITCHES

in FRONT DOOR

There are fly switches installed in the front door. These are the start, drain, manual wash, rinse fill
and heater switches.

Before working on the machine. It is important that the power be turned off at the customer's
circuit breaker to prevent the possibility of electrical shock; trip the breaker to the "Off" position.

The five rocker switches are mounted in a rectangular hole held in position by a bracket. These
switches, are designed to be released from the inside and pushed outward. The spring sides must
be depressed to release the switch and bracket from the hole. To remove the bracket from the
switch, wedge a screwdriver In between them then lift up and move off.

If the switch to found to be defective, mount a ne w one into the bracket and Insert It Into the hole In
the control box. Make sure that the tab on the switch is in the proper notch on the bracket for easy
operation of the switch. Replace the wires from the used switch terminal by terminal on to the new
switch.

Power can now be applied to the dishwasher and run through cycles checking all
operations.

INTERLOCK SYSTEM

The Interlock System is designed to preve nt the machine from operating when the front door Is
opened or not latched property.

The Interlock System consists of two safety switches, one mounted so that the door latch has to be
closed to complete the circuit. The other switch is located so that a pin on the machine depresses a
safety switch mounted on the door, to complete the circuit. Either of these switches, if not
depressed, will prevent the machine from operating. Basically, the door must be closed and the door
latch locked in order for the machine to function.

CHECKOUT

(INTERLOCK SYSTEM)

Note: All eletrical checks should be made by qualified service personnel.

If it's determined that the proper power is being applied to the machine's incoming terminal
blocks, then further check of the safety switch should be made.
Note: This checkout would only be performed if none of the systems of the machine

operate. This would mean that none of the switches, when depressed, will perform
the function noted for that switch.

Example: Drain, fill, start or manual wash switches.

Proceed with checkout

1. Remove power to the machine by turning circuit breaker that protects the machine to "off"
position.

2. Open the front door and remove screws holding inside panel of door.

3. Disconnect one wire from the switch closest to the door latch and using an ohmmeter,
depress the lever of the switch and check that there is continuity across that switch. If
there is no continuity, replace switch.

4. Check second safety switch located in top lefthand comer of door. Remove wire from one
side of the switch and check for continuity with ohmmeter when switch is depressed. If
there is no continuity, replace switch.

5. Replace Inside door panel.

6. Re -apply power & re-check operation.

THERMOSTAT ADJUSTMENT

THERMOSTAT

The thermostat can be adjusted by turning screw #1 (see picture) on the thermostat control box
cover. (Remember the present setting, in case the problems are elsewhere in the control circuit.) A
CW rotation is used to obtain a lower temperature setting and a CCW rotation is used to obtain a
higher temperature setting. A 1/4 turn of screw #1 changes the temperature approximately 15 °F. If
screw #1 is turned all the way to its top in either direction, adjust screw #2 as follows.

Note: Do not touch the screw sealed with re d paint. When adjusting screw #2, power should be

disconnected during adjustment.

Set screw #1 so that it can be turned equal distances in either direction, then:

— If screw #1 stopped while turning in CW direction, turn screw #2 in CW direction, slowly and

only 1/4 of a turn or less per complete cycle of the unit.

— If screw #1 stopped while turning in CCW direction, turn screw #2 In CCW direction, slowly

and only 1/4 of a turn or less per complete cycle of the unit.

Three-fourths of a turn will bring the thermostat to approximately the same setting obtained when
screw #1 stopped. Check the present temperature setting before attempting any further
adjustments. Use screw #1 for any further adjustments.

Making large moves In adjusting may cause misalignment, thus increasing chances that further
adjustment cannot be made and thermostat will have to be replaced.

functioning on 110/130V for 60 cycle and 220/240V (or 50 cycle system and the power system
functioning on 208/230V for both systems. The heat circuit is controlled by a heat switch
(mounted on coat door) and a thermostat (mounted near thermometer) which activates the coil
on the heat relay. When higher temperature is required, power is applied to the heaters when
the contacts of the heat relay are closed. Should the rinse tank thermometer read either too
high or too low, follow checkout below.

Checkout of Heater System for Rinse Tank: (Refer to drawing, Figure #2)

Note: The following checkout should be done by a qualified service person or electrician.

1. Turn off power to machine by tripping circuit breaker to "off" position.

2. Remove front kick plate below door.

3. Make sure rinse temperature is below 180°.

4. Reapply power and observe heat relay (2pole) letter E, figure 2, (next to timer) as heat
switch Is turned on and off several times.

1. If heat relay contacts do not close, with heat switch on:
a. Check power supply at Position 1 on terminal board X. Voltage should be 110VAC

on 60 cycle machine or 220VAC on 50 cycle machine (L1-L2).

b. Check Position 2; voltage should be 110V on 60 cycle machine or 220V on 50 cycle

machine. If not, check switch as necessary.

c. Check Position 3; there should be "zero" volts there. If not. read just thermostat per

thermostat Instructions.

d. If voltage is being applied to Positions 1 and 2, then the relay should be replaced;

coil on relay probably defective.

2. To determine If elements are working:
a. There's an Insulated movable bar on the heat relay across the top of the two

contacts. With an insulated probe, depress the bar and observe rinse thermometer:
the temperature should rise noticeably in a minute or two. If It moves very slowly. It
would indicate that one element Is defective. If It moves consistently higher at a
good rate, the elements are okay.
Note: A check with an amp probe. If available, can be made.
The elements together should draw 20 amps: one element will draw only 10 amps.

Replace element If found defective.

3. If the heat relay closes:
a. Check power supply at Position 4 on terminal board X, right hand view. It should be

220V approx. It not, check circuit breaker at customers panel: replace if defective.

b. Check power at Position 5; voltage should be 220V. If not, check connections and

wires for breaks: replace as necessary.

c. With heat switch on and relay closed, check power at Position 6: voltage should be

220V. If not, replace heat relay.

d. If No. 3 above checks out okay, check at Position 7: voltage should be 220V. If not,

check wiring from heat relay to elements for loose connections or-broken wires:
repair as necessary.

WASH TANK HEATER SYSTEM

Function:

The Wash Tank Heater Control system is electrically connected in the circuit to operate on
220V regardless whether system is 60 or 50 cycle. The heat circuit Is controlled by a heat
switch (mounted on front door), water level control (mounted middle of control panel), and
thermostat (mounted near thermometers). When higher temperature is required, power is
applied to the heater element through above controls. Should the wash tank thermometer read
either too high or too low, follow checkout below.

Checkout of Heater System for Wash Tank: (Refer to drawing. Figure 1.)

Note: The following checkout should be done by qualified service personnel or electrician.

1. Ready machine for normal dishwashing operation with wash tank water at proper level

2. Remove front kickplate below door.

Note: Power's still applied to circuit, so be careful.

3. Check power to machine at Position 1; terminal board X should read 110V on 60 cycle, or
220V. 50 cycle machine (L1-L2). If not, check customer's circuit breaker. If defective,
replace.

4. Wash temperature should be 130° or less to proceed.

5. Observe water level control, letter "B" (with front door closed and latched). Turn heat
switch on and off several times. Relay and contact points (Inside clear plastic case on
water level control) should move back and forth.

AA If water level control relay doesn't close, refer to page on Water Level Control's

function and checkout.

BB If water level control relay does close, proceed with heat switch on.

1. Check voltage at Position 1 on terminal board X. Voltage is 110 on 60 cycle machine or
220V on a 50 cycle machine (L1-L2).

2. Check Position 3, Figure 1: there should be no voltage. If there is voltage, then adjust
thermostat (refer to page on Thermostat Adjusting).

3. Check Position 2 at heat switch A. There should be 110V on 60 cycle. There should be
220V on 50 cycle.

4. Check Position 5. Figure 1, voltage should be 220. If not, check Position 8, there should
be 220V.

5. Temperature should rise slowly, a check with an amp probe would indicate If the
element Is drawing the correct amperage. Replace element if defective.

WATER LEVEL CONTROL

AS USED ON 24
P/N 0204500 (110V, 60 cycle)
P/N 0205000 (220V, 50 cycle)

Function:

The water level control device to utilized on this machine to automatically control the cutoff of
the wash tank heater when water drains from the wash tank.

Note: All electrical checks should be made by qualified service personnel.
The control is designed to sense when the proper water level is maintained. At this time, the

relay in the clear plastic case will activate, closing the circuit to the thermostat which
completes the wash tank heat circuit as it closes. If one of the following problems exist, this
unit should be checked out as shown below.

Symptoms of Leve l Control Failure:

1. Wash heater circuit Is not activated with water at proper level (up to overflow level on
overflow pipe) In wash tank.

2. Wash heaters remain on when water drained from wash tank. (Sometimes caused by
deposits on probe)

Proceed with Checkouts:

1. Remove power source to machine by moving circuit breaker to "off" position.

2. Remove screws holding lower kick plate on front of machine and locate water level control
(sketch below).

3. Remove, mark and Insulate, for easy replacement, wires going to letters C & H.

4. Re -apply power, turn on heat switch. With an insulated wire. connect Jumper wire between
terminals C & H (24 volt system).

5. If relay operates, (he water level control action can be deemed operational; then other
causes sh ould be explored.

6. If relay doesn't operate, replace control.

7. Remove power source once again and replace wires that were removed in step three to
original terminals (see trouble shooting section for other possible causes).
