F232101

Safety

Safe Operating Environment

Safe operation requires an appropriate operating environment for both the operator and the machine. If questions regarding safety arise, contact the factory immediately.

Environmental Conditions

● Ambient Temperature. Water in the machine will

freeze at temperatures of 32°F (0°C) or below. Temperatures above 120°F (50°C) will result in

more frequent motor overheating and, in some cases, malfunction or premature damage to solid state devices that are used in some models. Special cooling devices may be necessary.

Water pressure switches are affected by increases and decreases in temperature. Every 25°F (10°C) change in temperature will have a 1% effect on the water level.

● Humidity. Relative humidity above 90% may

cause the machine’s electronics or motors to malfunction or may trip the ground fault interrupter. Corrosion problems may occur on some metal components in the machine.

If the relative humidity is below 30%, belts and rubber hoses may eventually develop dry rot. This condition can result in hose leaks, which may cause safety hazards external to the machine in conjunction with adjacent electrical equipment.

● Radio Frequency Emissions. A filter is available

for machines in installations where floor space is shared with equipment sensitive to radio frequency emissions.

● Elevation. If the machine is to be operated at

elevations of over 3280 ft. (1000 m) above sea level, pay special attention to water levels and electronic settings (particularly temperature) or desired results may not be achieved.

● Chemicals. Keep stainless steel surfaces free of

chemical residues.

DANGER

Do not place volatile or flammable fluids in any machine. Do not clean the machine with volatile or flammable fluids such as acetone, lacquer thinners, enamel reducers, carbon tetrachloride, gasoline, benzene, naptha, etc. Doing so could result in serious personal injury and/or damage to the machine.

SW002

● Water Damage. Do not spray the machine with

water. Short circuiting and serious damage may result. Repair immediately all seepage due to worn or damaged gaskets, etc.

● Ventilation. The need for make-up air openings

for such laundry room accessories as dryers, ironers, water heaters, etc., must be evaluated periodically. Louvers, screens, or other separating devices may reduce the available air opening significantly.

F232101

Safety

Replace all panels that are removed to perform service and maintenance procedures. Do not operate the machine with missing guards or with broken or missing parts. Do not bypass any safety devices.

SW019

CAUTION

Machine Location

● Foundation. The concrete floor must be of

sufficient strength and thickness to handle the floor loads generated by the high extract speeds of the machine.

● Service/Maintenance Space. Provide sufficient

space to allow comfortable performance of service procedures and routine preventive maintenance.

This is especially important in connection with machines equipped with an AC inverter drive.

Consult installation instructions for specific details.

Input and Output Services

● Water Pressure. Best performance will be

realized if water is provided at a pressure of 30 – 85 psi (2.0 – 5.7 bar). Although the machine will function properly at lower pressure, increased fill times will occur. Water pressure higher than 100 psi (6.7 bar) may result in damage to machine plumbing. Component failure(s) and personal injury could result.

● Steam Heat (Optional) Pressure. Best

performance will be realized if steam is provided at a pressure of 30 – 80 psi (2.0 – 5.4 bar). Steam pressure higher than 125 psi (8.5 bar) may result in damage to steam components and may cause personal injury.

● Compressed Air. For machines requiring

compressed air service, best performance will be realized if air is provided at a pressure of 80 – 100 psi (5.4 – 6.7 bar).

● Drainage System. Provide drain lines or troughs

large enough to accommodate the total number of gallons that could be dumped if all machines on the site drained at the same time from the highest attainable level. If troughs are used, they should be covered to support light foot traffic.

● Pow er. For personal safety and for proper

operation, the machine must be grounded in accordance with state and local codes. The ground connection must be to a proven earth ground, not to conduit or water pipes. Do not use fuses in place of the circuit breaker. An easyaccess cutoff switch should also be provided.

WARNING

Ensure that a ground wire from a proven earth ground is connected to the ground lug near the input power block on this machine. Without proper grounding, personal injury from electric shock could occur and machine malfunctions may be evident.

SW008

Always disconnect power and water supplies before a service technician performs any service procedure. Where applicable, steam and/or compressed air supplies should also be disconnected before service is performed.

For machines equipped with optional steam heat, install piping in accordance with approved commercial steam practices. Failure to install the supplied steam filter may void the warranty.

F232101

Safety

AC Inverter Drive

Machines equipped with the AC inverter drive require special attention with regard to the operating environment.

● An especially dusty or linty environment will

require more frequent cleaning of the AC inverter drive cooling fan filter(s) and of the AC inverter drive itself.

● Power line fluctuations from sources such as

uninterruptible power supplies (UPS) can adversely affect machines equipped with the AC inverter drive. Proper suppression devices should be utilized on the incoming power to the machine to avoid problems.

● A clean power supply free from voltage spikes

and surges is absolutely essential for machines equipped with the AC inverter drive. Nonlinear inconsistencies (peaks and valleys) in the power supply can cause the AC inverter drive to generate nuisance errors.

● If voltage is above 230 Volt for 200 Volt

installations or above 440 Volt for 400 Volt installations, a buckboost transformer is recommended. If voltage is above 240 or 480, a buckboost transformer is required.

Misuse

Never use this machine for any purpose other than washing fabric.

● Never wash petroleum-soaked rags in the

machine. This could result in an explosion.

● Never wash machine parts or automotive parts in

the machine. This could result in serious damage to the basket.

● Never allow children to play on or around this

machine. Death or serious injury can result if children become trapped in the machine. Do not leave children unattended while the machine door is open. These cautions apply to animals as well.

● Sufficient space to perform service procedures

and routine preventive maintenance is especially important for machines equipped with the AC inverter drive.

Operation

Theory of Operation

The design of the washer-extractor emphasizes performance reliability and long service life. The cylinder, shell, and main body panels are fabricated of stainless steel.

Electrical controls for the washer-extractor are housed in separate enclosures. The front control module houses the WE-6 computer, the fuse/relay board together with its interface board, water level switches, a circuit breaker which interrupts control voltage, and other control components. The rear control module houses the AC inverter drive and its components.

All variable-speed freestanding machines use the AC inverter drive control, which provides programmable motor speeds using a single motor. The AC drive interface board converts motor logic from the WE-6 computer to the correct signals for the AC inverter drive. In addition, all logic inputs to the computer are routed through this board.

Two separate bearings support the cylinder on 135-pound and 250-pound models.

The cylinder is constructed with four lifters or ribs that lift the laundry from the bath solution when the cylinder rotates at slow speed and then allow the laundry to tumble back into the bath. This mechanical action accomplishes the washing function. The cylinder is perforated, allowing the water to drain from within during the wash and extract steps.

On 135-pound capacity models, water enters the machine through electromechanical water valves. On 250-pound capacity models, water enters the machine through pneumatic water valves on the rear of the machine. (Pneumatic water valves are an option on 135-pound capacity models.)

Water valves on both washer-extractors are controlled by the microcomputer. The microcomputer also controls the drain and door lock. In addition, it selects the water levels according to the programmed cycle. Vacuum breakers are installed in the water-inlet plumbing to prevent backflow of water.

Air-operated drain valves hold water in the machine during the wash, soak, and rinse steps. The drain valve is normally open, which means that it closes only when air is applied, thus allowing the machine to drain in the event of a power failure.

A door-lock system prevents opening of the stainless steel door when a cycle is in progress. It also prevents operation of the washer-extractor when the door is open.

The doorbox contains the Hall-effect door-locked and door-closed sensors and the door unlock solenoid.

The stainless steel supply dispenser is located on the left side panel of the washer-extractor, viewed from the front. The dispenser has five supply compartments, numbered 1 – 5, starting from the rear of the machine. The compartments hold supply cups that are used for either liquid or dry supplies. A nozzle flushes supplies from the cups with water for the time programmed in the cycle.

Liquid supplies can be injected directly into the cups by a customer-supplied external chemical supply system. On 135-pound capacity models, five hose barbs on the rear of the washer-extractor facilitate connection to an external supply system. On 250-pound capacity models, five strain reliefs on top of the supply dispenser provide the same connection capability.

F232101

Operation

Emergency Stop Button

On 135-pound capacity models, a red emergency stop button is located on the upper right-hand corner of the control panel. On 250-pound capacity models, the emergency stop button is on the left side of the washerextractor front. Push the button in to stop the washerextractor. Pull out to reset.

Wet Clean Features

The washer-extractor is equipped with the following wet clean capable features: One-half wash speed allows gentle mechanical action during wash. Eight supply signals provide not only normal laundering signals to dispense detergents, bleaches, softeners, sours, etc., but also chemicals unique to wet clean processing.

Wet Clean Capabilities

Differences in WE6 prompt (setup) options

The WE6FRWC software provides the usual setup options:

● Degrees F / C

● One or Two drain

● Advance / No Advance

● Manual / No Manual

● Balance setting

In addition, the software provides Wet Clean / No Wet Clean. The Wet Clean / No Wet Clean option enables or disables wet clean functions. The prompt (setup) options are now as follows:

● CEN / FAR

● 1DRAIN / 2DRAIN

● ADV / NO ADV

● MANUAL / NO MAN

● WET CL / NO WCL

● BAL SW, BAL 1, BAL 2, BAL 3

F232101

Operation

Wet Clean Functions

Wet clean functions include a reduced wash speed capability and a recirculation pump capability. These functions are enabled by the WET CL / NO WCL prompt selection. Other wet clean features are permanently enabled, and can be used for other applications as well. In particular, extra supply capability (up to eight supplies, in two banks of four supplies), and additional agitation actions as outlined below.

Agitations:

● wash 1 - normal: 18 seconds forward / three

seconds off / 18 seconds reverse / three seconds off; repeat

● wash 2 - gentle: three seconds forward / 27

seconds off / three seconds reverse / 27 seconds off; repeat

● wash 3 - no rotation

● wash 4 - ten seconds forward / 20 seconds off /

ten seconds reverse / 20 seconds off; repeat

● wash 5 - uses most recent agitation; defaults to

wash 1 agitation

● wash 6 - super gentle: four seconds forward / 56

seconds off / four seconds reverse / 56 seconds off; repeat

● wash 7 - no rotation; drain 1 (sewer drain) open;

no attempt to refill to level

Using the auxiliary 1 (A1) and auxiliary 2 (A2) outputs for wet cleaning

The A1 and A2 outputs (so labeled on the solid state WE6 output PC board) can be made to operate as timed outputs, or to remain on until a drain step.

Reduced wash speed

Normally, the A1 output would govern optional reduced wash speed. This means that if the WE6 is prompted for “WET CL”, and then an auxiliary 1 “A1” step is programmed for any amount of time (one second is a good choice for time in the event of controlling reduced wash speed), the A1 output will remain on until a drain step, or until stop routine. Thereby the reduced wash speed remains in effect as long as A1 remains on.

For example, with “WET CL” prompt selected, a wash 1 agitation is wanted, but at reduced wash speed. Program auxiliary 1 step for one second, then program a wash 1 step. The A1 output will remain on during the wash 1 step, selecting reduced wash speed during the wash 1 step. Upon reaching a drain step, or upon entering the STOP routine, the WE6 will operate the machine at reduced wash speed (PROVIDED the machine is equipped with the necessary hardware for controlling reduced wash speed).

Control of an optional recirculation pump

The A2 output will also remain on until a drain or the STOP routine if the WE6 prompt is “WET CL” and if “1DRAIN” is selected. This would allow control of an optional recirculation pump by permitting the pump to continue operating during a wash step. For this control, program an auxiliary 2 “A2” step for one second or other suitable time, and the output would remain on until a drain step or until the STOP routine. The auxiliary 2 step would also go off upon entering a Wash 7 step.

Note that “2DRAIN” prompt will OVERRIDE wet clean control of auxiliary 2 output. If “2DRAIN” is selected that means that the auxillary2 output is reserved for controlling a second independent drain (not for integrated reuse - you should select “1DRAIN” for integrated reuse). Also, if “2DRAIN” is selected. the WE6 will not permit programming and auxiliary 2 step.

F232101

Operation

WE-6 Microcomputer

The WE-6 microcomputer control is a fieldprogrammable solid-state control capable of storing and running up to 39 preprogrammed ready-to-use cycles.

Cycle 01 is a test cycle used to verify proper operation of the machine. With the exception of Cycle 39, the remaining cycles are complete wash cycles or specialty cycles designed to handle various fabrics at specific water temperatures and levels. Cycle 39 is designed to test an external chemical injection supply system.

A detailed description of the cycles can be found in the

Programming section of this manual under Preprogrammed Cycles. (If this washer-extractor’s

computer has been equipped with special preprogrammed cycles, a separate insert listing these cycles has been included in the resealable plastic bag which contained this manual.)

Never turn the power off while the Program Mode switch is in the PROGRAM position. Such action will disorder portions of the programmed data, necessitating reprogramming of some or all of the existing cycles. Always return the switch to RUN position before turning the power off.

Never leave the mode switch key inserted in the switch lock where it may be accessible to unauthorized personnel not familiar with programming procedures.

The computer control in this washer-extractor is continuously on the alert for problems within the machine. When the computer detects a problem, it immediately flashes a letter or number or both on the display. It may activate the signal buzzer as well.

LED Display

The WE-6 microcomputer has a six-digit LED display. References to display indications pertain to the first four digits of the display, reading left to right. The last two digits on the right side of the display will indicate either the last cycle used or the current cycle in progress. Refer to Figure 6.

Operation

Start-Up

Turn on the main power source (circuit breaker or cutoff switch on the wall).

When AC power is turned on, the front panel display will show the program (ROM) identification code.

This identification code will appear for approximately five seconds. Then the computer display will flash “POWER” and “WA I T ” alternately for two minutes.

The display will then show “NEXT00” to indicate that a cycle can be selected. This display will be shown at all times that power is on between cycles, indicating that the door-unlock solenoid will function if the doorunlock button is pressed. The washer-extractor is then ready for loading and unloading.

Opening Door

Use left hand to press and hold the door unlock button located on the top of the doorbox cover. Use right hand to turn door handle upward and swing the door right to open. Refer to Figure 8.

Loading and Unloading

CAUTION

Be careful around the open door, particularly when loading from a level below the door. Impact with door edges can cause personal injury.

SW025

Load the washer-extractor to full capacity whenever possible, but do not exceed the rated dry-weight capacity of the machine if the fabric to be washed is quite dense, closely woven, and heavily soiled. Overloading can result in an inferior wash. The operator may need to experiment to determine load size based on fabric content, soil content, and level of cleanliness required.

When loading is complete, ensure that all fabric is inside the basket. Then close and lock the door.

NOTE: When washing items which may disintegrate or fragment, such as mop heads or sponges, use laundry nets to prevent drain blockage.

Tilt Option

Cabinet freestanding 250-pound capacity washerextractors equipped with the tilt option offer the operator more convenient loading and unloading.

Forward tilt and two-way tilt are available on 250-pound capacity models.

The tilt mechanism operates independently of the WE-6 microcomputer. Mechanical interlocks are in place, however, which do not permit operation of the washer-extractor while the tilt mechanism is raised, and vice versa.

U150R3

The mechanism is controlled via a pendant switch (refer to Figure 9), which is suspended from a point just above the electrical panel on the left side of the washer-extractor. Access height has been determined based upon an average-sized person.

The tilt mechanism is pneumatically operated. Airstroke actuators raise and lower the machine when the tilt is selected. On two-way tilt mechanisms, pneumatic pins positioned at strategic points along the mechanism frame allow it to achieve both forward and reverse tilt. When reverse tilt is selected, pins in the rear of the mechanism engage and prevent the rear of the machine from being raised. When forward tilt is selected, pins in the front of the mechanism prevent the front of the machine from being raised.

NOTE: When the washer-extractor/tilt mechanism assembly is lowered, it must properly seat itself in order to be operable. Improper seating will result in total inoperability of the WE-6 microcomputer, in which case it will be necessary to raise and lower the assembly again. Further, once the assembly is raised, it must be lowered and properly seated before it can be raised again.

Forward Tilt Option

Washer-extractors equipped with the forward tilt option are capable of tilting as much as 13° forward.

Upon completion of a cycle, the basket can be unloaded as follows:

1. Open the loading door and secure it to the door latch on the right side of the washer-extractor.

2. Turn the selector dial on the pendant switch right to the forward tilt position. Refer to Figure 9.

3. While holding down the green ENABLE button, press the black FORWARD button. Refer to Figure 9. The washer-extractor will slowly tilt forward, and the basket will rotate clockwise.

4. Unload the washer-extractor.

5. To lower the washer-extractor, turn the selector dial back to the center position. Refer to Figure 9.

6. Unlatch and close loading door.

CAUTION

Two-Way Tilt Option

Washer-extractors equipped with the two-way tilt option are capable of tilting as much as 13° forward or backward.

The forward tilt is used primarily for unloading. The reverse tilt is used for loading the washer-extractor.

To load the washer-extractor, follow this procedure:

1. Open the loading door and secure it to the door latch on the right side of the washer-extractor.

2. Turn the selector dial on the pendant switch left to the reverse tilt position. Refer to Figure 9.

3. While holding down the green ENABLE button, press the black REVERSE button. Refer to Figure 9. The washer-extractor will slowly tilt backward and the basket will rotate counterclockwise.

4. Load the washer-extractor.

5. To lower the washer-extractor, turn the selector back to the center position. Refer to Figure 9.

6. Unlatch and close loading door.

Upon completion of a cycle, the basket can be unloaded as follows:

1. Open the loading door and secure it to the door latch on the right side of the washer-extractor.

Two-Way Tilt Inductive Proximity Sensor Adjustment

The Programmable Logic Controller (PLC) uses four inductive proximity sensors on the two-way tilt platform to detect the position of the frame and prevent unsafe operation. These sensors MUST be in place and operational.

Front Down and Rear Down Sensor Adjustment

The front down sensor is located next to the front left lock cylinder mounted on the lower (floor) frame. The rear down sensor is located next to the rear left lock cylinder mounted on the lower (floor) frame. Adjust these two sensors so that the plastic face is 4 to 6 mm from the edge of the upper channel when fully seated on the lower frame. The sensor LED should be on when the frame is fully seated and should turn off before the machine has lifted more than 3/4 in. out of the associated pivot point.

Seated Sensor Adjustment

Adjust the seated sensor so that the plastic face is 4 to 6 mm from the edge of the upper channel when the frame is fully seated. The sensor LED should be on when the frame is fully seated and should turn off before the upper channel edge has lifted more than 1/2 in. at the sensor face.

Up Sensor Adjustment

2. Turn the selector dial on the pendant switch right to the forward tilt position. Refer to Figure 9.

3. While holding down the green ENABLE button, press the black FORWARD button. Refer to Figure 9. The washer-extractor will slowly tilt forward, and the basket will rotate clockwise.

4. Unload the washer-extractor.

5. To lower the washer-extractor, turn the selector dial back to the center position. Refer to Figure 9.

6. Unlatch and close loading door.

Adjust this sensor so that it is on when the washerextractor is fully tilted in either direction and off when the washer-extractor is seated or in transition from one position to another. This adjustment will vary somewhat from machine to machine because it is impossible to seat the washer-extractor on the tilt frame in exactly the same relative position every time.

Operation

Supply Dispenser

Dry supplies are placed in the supply dispenser compartment cups prior to the start of each cycle.

Liquid supplies can be injected directly into the supply dispenser by an external chemical supply system.

NOTE: Supply dispenser compartment cups must not be removed when an external chemical injection supply system is attached to the washerextractor.

Cycle Selection

NOTE: Press keys at their centers just hard enough to activate them.

Find the cycle number of the desired wash cycle from the Stardard Cycle Charts in the Programming section of this manual. Cycle numbers must be twodigit numbers from 01 to 39.

Press the numbers desired on the keyboard and note that these numbers are displayed after “NEXT”.

When keys are pressed on the keyboard, a beep will be heard. If an error is made, press the numbers again. As numbers are entered, they move from right to left on the display.

NOTE: If the 135-pound capacity washer-extractor is equipped with both steam and electric heat, the selector switch on the valve panel must be in the correct position for the desired heat source, down for steam heat, up for electric heat. (Electric heat is not available on the 250-pound capacity model.)

Cycle Execution

To start the selected cycle, press the Start key. If the selected cycle number is not in the computer memory, the display will show “NCYC”. If this happens, select another cycle. Otherwise, the display will now show the first step. For example, if the display reads

“HL01”, “HL” represents a hot fill to low level, and “01” indicates that this is the first step of the cycle.

To begin the cycle at any step other than the first step, press the Advance key to advance through the cycle to the desired starting point. (The Advance key is enabled at the factory and can be disabled at the laundry site.) Then press the Start key.

NOTE: Computer will not start in a spin step. It should be started in the drain step just prior to the spin.

It is possible to skip to the next step in a cycle, with the exception of a drain step: Drain steps must be allowed time to complete.

When the display shows the step desired to begin the cycle, press the Start key.

If the door is not locked, the display will indicate “CLOSE” and “DOOR”. If this occurs, be sure the door is closed and locked and press the Start key again.

If the LED indicator lights for the computer outputs indicate that one or more outputs are activated but the washer-extractor is not functioning according to the output or outputs indicated, contact a service technician.

As water fills the washer-extractor, one or more of the indicator lights located to the left of the keyboard will come on and stay on until the required water level is reached. LED dots located in the upper left corner of the last three digits on the right of the display will illuminate to indicate the water level(s) reached:

● When the indicator dot in the last digit on the

right is lit, the low water level has been reached.

● When the dot in the next-to-the-last digit is lit,

medium water level (optional) has been reached.

● When the dot over the third digit from the right

has been lit, high level has been reached.

The cycle will continue until its completion. Then the display will show “DONE”.

As the cycle proceeds, the display will show the function being executed, the step number, and the cycle number selected. Pressing the Edit Cycle key while the cycle is running will cause the display to show the remaining cycle time in minutes. Pressing this key again will return the display to normal.

F232101

Operation

Test Cycle

Cycle number 01 is a test cycle used to analyze washer-extractor functions. Refer to the Programming section of this manual.

Step 01 in cycle number 01 is a cold fill to low level. This step is designed to give not quite enough time to complete a fill, causing the display to read “FILL”. Press the Start key to continue the fill, and the test cycle will proceed.

Step 02 in the test cycle is a drain step. Again, the time allotted is shorter than it would be in a normal cycle. The display will read “EMTY”. To proceed, press the Start key.

The steps in the test cycle are relatively short, with the exception of steps 03, 21, 25, 27, 28, and 29. These can be shortened by pressing the Advance key to go on to the next step.

The operator may skip to any next step in the cycle with the exception of a drain step; drain steps must be allowed to complete. To skip forward in the test cycle, press the Advance key.

Wet Clean Testing

Wet clean processing outputs are tested through the energizing of the Auxiliary 1 output in step 18 and Auxiliary 2 output in step 19. Steps 30 through 33 are designed to test water reuse processing, if this option is installed. If it is not, the outputs associated with each step will be energized, and the cycle will conclude normally.

NOTE: Prompts for “1DRAIN” and “WET CL” must be selected when prompting the WE-6 microcomputer in order for steps 18 and 19 to work properly for wet clean processing.

NOTE: The Advance feature may be disabled. Refer to Prompting the WE-6 in the Programming section of the manual.
