TIMER for MODEL 24L
General Description:
The timer is a self-contained (frame mounted) timer of the repeating cycle type. It is mounted on the lower control
panel of the Jackson Dishwashing Machine to control the automatic functions of this machine. It consists of a
clock motor which operates on 60 cycle, 110VAC. In addition to the clock motor, the timer also contains a driven
cam arrangement which operates five 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 360 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 micro switch second from the timer motor controls the wash/rinse and uses the NC contact. The
micro switch third from the timer motor controls the rinse/fill and uses just the NC contact. The micro switch fourth
from the timer motor controls the drain and uses just the NC contact. The last micro switch, fifth from the timer
motor, controls the sanitizing pump 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 in the door 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 by one function being executed all the time or the 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 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 1/2 raised and 1/2 depressed edge.
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 timers 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.

CONNECTION TERMINALS
in FRONT DOOR
There are three switches installed in the door's upper right hand corner. These are the start, drain, and fill.
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.
Remove inside door from machine by removing the eight screws on the flanged section of the inside door
panel. The three switches are all snapped into place in individual rectangular holes. By using a screw driver, it
is possible to pry up the chromed flange on each side away from switch and remove the switch from flange.
Little pressure should be used to prevent damage of switch and flange.
After the switch has been checked to see if it is defective, replacement can be made by placing the new switch
close to the defective switch and moving one wire at a time, transferring them to the same terminals on the
new switch until all wires have been reconnected. If this is not practical, pull the wires loose, one at a time, tag
them and reconnect them according to the electrical diagram.
Put all switches back into place making sure switch protrudes through front door properly.
Note: Two click positions on bracket. Replace inner door panel. Seal top of inner door to outer door with a
waterproof sealant. Power can now be applied to the dishwasher and run through cycles, checking
all operations.

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 electrical checks should be made by qualified service personnel.
If it is determined that the proper power is being applied to the machine's incoming terminal
blocks, then further check of the interlock system 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 switches.
Proceed with checkout.
1. Remove power to the machine by turning circuit breaker that protects the machine to OFF position.
Note: It may be necessary to disconnect the door springs to prevent door from closing when inner
door is removed.
2. Open the front door and remove screws holding inner 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 right hand corner of door, viewed with inner door off. 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 inner door panel.
6. Apply power and check operation.

PERISTALTIC PUMP SANITIZING
DISPENSING SYSTEM
(FOR WALL MOUNT DISPENSING SYSTEMS)
The three peristaltic pumps are mounted in the dispenser box which is attached to the wall or
unit. The pump receive their electrical signals from two sources.
The first source is the rinse/fill switch which is used to prime the pump when it is first put into
operation and then every time the unit Is filled with fresh water to start a new meal period.
The second source is the timer which activates the pump during the fill cycle of the unit and
allows it to drop 15 milliliters of sanitizing solution into the rinse water.
Checkout of Sanitizing Agent Injector
The pump can be deemed operational if the following items are observed:
1. If the cam roller assembly rotates during each cycle.
2. If the solution is observed passing through the tube.
Note: Both of these operations must be observed to determine if the sanitizing agent is
being dispensed.
It it is determined that the unit is not operating correctly, the following procedures will aid in
correcting the problem:
1. Make certain that the tube is in the bottle of solution.
2. Make certain that there are no cracks in the tubing and particularly in the pump hose.
3. Check all wire connections on the pump, the timer cam, and the rinse/fill switch.
4. Check to see that there is no debris in the tubes.
5. Make sure that the tubing is inserted into the pump hose so that air is not drawn into the
system.
