ABOUT THIS MANUAL

ËScope—This instruction manual is intended to provide operating and troubleshooting instructions for the

C4A electronic coin washer-extractor control. Refer to the INSTALLATION AND SERVICE manual for information on machine installation procedures, mechanical requirements, preventive maintenance, service procedures, and mechanical parts identification. Refer to the SCHEMATIC MANUAL for electrical parts identification and electrical troubleshooting.

ËThe Power Up Sequence—Verify that the machine behaves as described in “OPERATION OF

C4A . . . ” (see Table of Contents). Any other display indicates an error condition which must be corrected before the machine will operate. See “HOW TO CORRECT ERRORS WITH THE C4A CONTROL.”

ËQuick Reference Tabs—The tabs along the right edge of the manual mark vital information.

SAFETY—READ FIRST—Safety instructions must be read before operating machine. COMMISSIONING—Commissioning instructions ensure proper start up. CONTENTS—See Table of Contents for section/page numbers of cross references used herein. CHANGES/NEW MATERIALS—These, if any, will be found in an envelope inside the rear

cover.

ËManual Number/Date Code (When To Discard or Save)—The manual number/date

code is located on the inside front cover, upper right corner just above the manual name. Whenever the manual is reprinted with new information, part of this number changes. If the date code after the “/”

changes, the new version applies to all machines covered by the old version, but is improved— thus the old version can be discarded. If the manual number before the “/” changes, the new manual covers only n ew machines. Example: Discard MATMODELAE/8739CV when MATMODE LAE/8739DV is

received (minor improvements). Also, discard MATMODELAE/8739DV when MAT- MODELAE/8746AV is received (major improvements). But keep MATMODELAE/8746FV when MAT- MODELBE/8815AV is received, since the new manual no longer applies to machines originally shipped with the old manual.

ËDocuments and Change Bars—The individual documents comprising this manual use the same

revisio n criteria as the manual. Text documents als o display change bars. Example: When section MSOP0599AE/9135BV becomes MSOP0599AE/9135CV, change bars with the letter “C” appear next to all changes for this revision. For a major rewrite (e.g., MSOP0599AE/9226AV), all change bars are deleted.

A tremendous amount of potential energy is stored in the rotating cylinder of any washerextractor (even at slow speed). Washer-extractors are equipped with a

door interlock

designed to prevent the door from being opened if the cylinder is turning and to prevent the machine from starting unless the door is closed and locked.

Some coin machine models permit the door to be opened only during the first few minutes of the formula and only while the machine is rotating in wash speed. If the door is opened, the drain valve opens immediately, the machine stops, and (provided the machine still has electric power), on most models a brake is immediately applied.

—Contact with goods being processed can cause the goods to wrap around your body or limbs and dismember you. The goods are normally isolated by the locked cylinder door.

• Do not put any part of your body in the machine while it is moving.

• Do not operate the machine with the door open.

• Do not attempt to open the door or reach into the cylinder until the cylinder is stopped.

• Do not touch goods inside or hanging partially outside the turning cylinder.

• Do not open the cylinder door with water in the cylinder.

• Do not tamper with or disable any safety device or operate the machine with a

malfunctioning safety device. Request authorized service.

—A locking cylinder door can entrap anyone who enters

the cylinder. The person can be killed or seriously injured.

Most modern coin operated washer-extractors have a door interlock which, for safety, locks the door when the cycle starts (or a short time later). The door is unlocked when the cycle ends. If power is lost, the door unlocks so that goods may be removed if desired. When power is restored and the door is closed, most machines resume the interrupted cycle without additional coins and the door is again locked.

In a tragic incident, a small child was placed, climbed, or was helped to climb into a front loaded coin machine and the door was then closed behind him. The door locked, the machine started running and the child was scalded to death.

The laundry owner/operator must guard against entrapping anyone in a washer-extractor by doing the following:

—The National Electric Code (article 430-112) requires a clearly marked electric disconnect switch in sight and no more than 50 feet from each machine. (Local codes may have additional requirements.) Make disconnect switches readily accessible, but not so accessible as to provide an attractive nuisance for playful children.

You are urged to consult your licensed electrician and take immediate steps to comply if your installation does not now meet the National Electric Code requirement.

$!

8]U^a\cWT2dbc^\Ta

—Post signs prominently in the laundry or use whatever additional effective means are available to inform the customer of the entrapment hazard, and how to minimize the hazard, including but not necessarily limited to the following:

1. that children must not be placed inside, nor be allowed to operate or play in or around any machine,

2. the location of the disconnect switch for each machine, and

3. what to do in the event of an emergency.

If the machine does not accept coins with the door open, proceed to Step 4.

Step 4.

With the door open, manually operate the door switch actuator 100 times (Figure 1). Operate the actuator for one second ON (depressed), then one second OFF (released). If the machine completed steps 1, 2, and 3 successfully, this tests if simply closing the door will permit a free wash.

If the machine starts while the door switch actuator is depressed,

immediately take your hand off the door switch actuator and take the machine out of service until the coin counter has been changed. Do not return the machine to service until it successfully passes all seven steps described herein.

If the machine does not start, proceed to Step 5.

Step 5.

With the door closed and the machine still in the “unarmed” condition (it has not yet accepted coins), turn the power ON and OFF 25 times at the wall-mounted power disconnect switch (Figure 2) or external circuit breaker. Turn power ON for five seconds, then OFF for five seconds). Observe if the machine starts at any time the power is turned ON. This tests if the coin counter will give a free wash when electric power is restored after power interruption while the machine was

take the machine out of service until the coin counter has been changed. Do not return the machine to service until it successfully passes all seven steps described herein.

If the machine does not start without coins at any time power was turned ON and OFF 25

times, you probably have a good coin counter. Proceed to step 6.

Step 6.

Insert the proper number of coins. Verify that:

• the machine starts only after the last coin is accepted, and

• the machine will then accept no more coins.

If the machine starts before the last coin is accepted or accepts more than the proper
