Introduction

The EX-HI-TEK model washer/extractor has been developed to cover the heavy duty requirements of hotels, motels, nursing homes, hospitals, professional laundries, restaurants, airlines, steamships, schools, colleges and all on-premises laundries where flexibility and quick formula variation, coupled with high quality automatic washing, are required.

The microcomputer controlled EX-HI-TEK model allows for complete programming of water temperatures, water levels, wash and extraction periods and supply injections.

The machines are free-swinging, i.e., the drum is moveable and spring suspended in relation to the frame. This minimises vibrations transferred to the frame thus simplifying installation, as no concrete base is required.

The high speed spin gives a G factor of approximately 300, providing very efficient water removal during the spin.

All parts of the machine which come into contact with the items being washed are made of heavy gauge surgical stainless steel, ensuring long life and lasting beauty, as well as full protection for no-iron fabrics. All electrical components are made accessible for servicing by simply removing the top panel.

This manual contains a technical description of the machine and instructions for its installation, operation and maintenance. Together with the wiring diagram which accompanies each individual machine it should be kept in a safe place for easy reference.

When ordering spare parts or contacting Wascomat for any purpose always give the machine serial number, model, voltage and other electrical characteristics appearing on the nameplate at the rear of the machine.

Electrical installation

Although the machines are fitted with thermal overloads in the motor windings and separate fuses for the control circuit, a separate threephase circuit breaker must be installed for all three-phase machines.

For proper overcurrent protection, check the data plate at the rear of the machine. Also consult local electrical code for special requirements.

The machine is equipped with a control circuit transformer, mounted on the control unit and connected for 220 volt operation. If your incoming voltage is below 210 volts move the wire connection to the 208 volt tab on the transformer. If it is above 230 volts move the wire to the 240 volt tab on the transformer.

Check the incoming power for a high voltage leg. If present, connect that line to L2 on the terminal block. Make certain it is not connected to the transformer.

Connect L1, L2, L3 and ground wires according to the markings of the terminal block. The cable is to hang in a large loose loop, supported by the clip of the terminal block.

To ensure proper operation the drum must rotate counter-clockwise (seen from the front) during extraction. If the drum rotates in the wrong direction interchange line L1 and L3 at the power connection terminal.

Mechanical and electrical design

General

This machine is a free-swinging model i.e. the outer drum and motor bridge are suspended in the machine chassis via a spring suspension with a strong spring in each corner of the machine. Each spring has a shock absorber which dampens the movement of the machine.

The inner drum is driven by two motors via a V-belt: one motor for washing and distribution speed and one for extract speed. The inner drum is mounted in the outer drum with two heavy duty bearings at the back plate and is sealed with two V-rings.

The two motors are suspended underneath on a motor support with a belt tensioning device. The motors are mechanically coupled to each other with V-belts. During wash and distribution speed the spin motor transmits power to the drum, through a clutch arrangement.

The water inlet and drain are both situated under the outer drum. This improves the flow during filling and prevents water vapour from entering the detergent compartment.

The robust square door is locked with a handle which is interlocked by a safety device when the machine is running.

The manual push buttons and card programmed control are fitted at the front of the machine.

All control and indicating components i.e. relays, delay unit, etc. are assembled under the top cover, easily accessible from the top of the machine for simplified servicing.

The machine housing consists of hot-dip galvanised, painted steel plates and stainless steel sheets, painted on the front and sides. It has a stainless door (and front, on request).

Frame

Description

The frame is constructed on the free-swinging principle, i.e. the washing drum is freely and resiliently suspended in the fixed frame.

The entire frame is constructed of U-shaped iron beams forming a stable and torsionally rigid structure.

The suspension device for the drum unit and motors consists of four posts, one in each corner, each with a robust spring to which the washing drum supports are attached. In order to prevent excessively great vibrations which can be caused by imbalance in the drum, a shock absorber is fitted between the drum and frame by each spring. (The EX 12 model has twin shock absorbers at the front.)

Repair instructions

If the out-of-balance cutout is repeatedly triggered

• Check the shock absorbers, replace them if required. Note that the shock absorbers should be fitted with the plunger rod upwards.

• Check the attachment of the springs:

- the spring is attached by a bolt from above: Check that it has been

properly tightened down.

The entire spring unit should be replaced in spring replacement.

Drum with bearings

Description

The inner drum is journalled to the outer drum by two robust bearings in a bearing housing which is bolted to the rear plate. The bearing unit supports the drum without any support being needed at the front. Shaft seals of the V-type, as well as O-rings, seal against leakage.

The space between the bearings is packed with grease during assembly. No additional grease is required.

The inner drum shaft is continuous, and the V-belt pulley is attached to the protruding journal by an adapter sleeve.

The outer drum end plate consists of two parts, the inner and outer end plates which are bolted to the bearing housing with through bolts. NOTE: The inner and outer end plates must not be taken apart when the bearings are replaced.

The outer drum and rear plate are held together by 3 straps. The outer drum is connected to its resilient suspension by four supports, bolted to

the end plates. It is important that these supports are not loosened from the rear plate during repairs.

Safety locking device

Description

The machine safety locking device includes a safety interlock system which prevents personal injury through the following precautions:

• The machine cannot be started until the door is shut.

• The door is automatically locked when the machine starts.

• It is not possible to open the door until 2-3 minutes have elapsed after the washing program has ended. This ensures that the drum is motionless when the door is opened.

Repair instructions

It the coil does not lock the door:

• Check that the coil is receiving 100-110 V DC voltage. Measure the coil to determine if there is an interruption.

• Check that the armature of the coil is not stuck.

• If necessary, replace the entire coil.

Other possible faults:

- Faulty microswitch.

- Faulty delay circuit.

- Moving parts jammed.

- Handle not in locking position.

Door lock solenid Y80

Mechanical and electrical design

Fig.

Page 24

Function

If the machine has not been energised within the last three minutes, the door will remain unlocked. When the machine is energised the door will be locked if a program is activated or if the drum is rotating. Upon completion of a program the door will be unlocked automatically as soon as the drum has stopped rotating.

If the power supply is cut to a machine which was energised the door will remain locked for three minutes, after which time it will be unlocked automatically.

The diagram below shows how the delay unit works. When the machine is energised the delay unit is fed phase and neutral on X194:5 and

X194:4 respectively. The door lock coil Y80 is then fed phase (via a normally closed relay contact) and neutral from X194:3. The relay coil acts on two conditions – that the drum is at a standstill and an "open" signal from the programmer circuit board:

• One side of the relay coil receives a zero potential signal when the rotation guard shortcircuits X193:1 and 2.

• The other side of the relay coil is supplied with phase from the programmer circuit board ("open" signal).

Both of these conditions must be fulfilled for the door to be unlocked. In the event of a power cut the capacitor will discharge via the relay and the door lock

solenoid. In this way the door lock solenoid continues to operate for three minutes, after which the door is unlocked automatically.

3. X194:1 - X194:4 Should be 220 V AC. If not, the "open" signal from the programmer circuit board is absent. Check pcb and cables between pcb and delay unit.

If the door is still locked, replace the delay unit.

Door does not lock

Conditions: door closed and wash program activated. Measure the voltage between the following points.

Rotation guard

Description

The rotation guard checks that the machine is completely at a standstill before the door can be opened. When the drum has been at a standstill for approx. two seconds the solenoid in the door lock is deactivated and the lock can be opened (provided that the machine has been emptied of water and the programmer has reset). The rotation guard also checks that the drum is revolving when the wash or extraction relays are operating.

The rotation guard consists of a circuit board in the automatic control unit and a sensor in a holder on the machine rear. There is a magnet on two of the spokes of the pulley. Each time a magnet passes the sensor, a contact closes inside the sensor and it relays a pulse to the rotation guard.

When the machine is at a standstill the rotation guard relays K1 and K2 are closed, which means that the delay unit and the HI-TEK receive confirmation that the drum is not moving, i.e. the rotation guard and the HI-TEK allow door opening.

Control unit

The control panel (1), mounted at the front, includes all components necessary for operating the machine, such as display window, control switches and a key-operated switch.

The printed circuit board (2) with the microprocessed electronic timer is mounted just behind the control panel.

Relays (3) and delay unit (4) are located at the top of the machine, easily accessible for service.

Electrical connections to the machine are made by quick-disconnect plugs.

Page 28

Relays

The HI-Tek models employ six relays. The relays control:

• the reversing wash action of the wash motor (2 relays)

• the distribution action of the wash motor

• the extraction motor (3 relays)

Construction

The body of the relay holding the stationary contacts is made of current-resistant plastic. A solenoid and a contact bank hold the moving contacts. The contacts are spring-loaded to assure the correct contact pressure.

The relay is constructed for continuous operation, whether mounted horizontally or vertically.

Screw-type terminals provide perfect connections even when one or two wires have different diameters.

Operation

When the solenoid is energized, the two halves of the magnet core are drawn together, pulling down the moving contacts, thus making or breaking the circuit. When the current cuts out, springs force the contact bank into its original position, thus closing or opening the circuits.

Trouble shooting

If the relay fails to operate despite power to the coil, turn off the power and check the solenoid by measuring the resistance across the terminals (1).

If the relay hums when power is applied, this indicates either a break in the insulator holding the moving contacts at the axle where it holds the top half of core (3) or a rusty core (4), which can be cleaned.

Make sure that the moving contact assembly (4) moves freely. Always replace burnt or pitted contacts (2)... do not reuse contacts.

Drive motors

Description

Both motors, one for wash and distribution and one for extraction, are installed on the same motor bridge. The motors drive the drum and are mechanically connected to each other by V-belts. On the EX 22 there is also an electromechanical clutch. The motors rotate at each others' speed during the wash speed, distribution speed and low extraction speed.

During high extraction speed the speed control on the EX 22 gives a signal to the electromechanical clutch. This disconnects the motors from each other mechanically. The wash motor now rotates at distribution speed and the extract motor at high speed.

On the EX 12 the power supply to the wash motor is disconnected by the speed control.

On the motor bridge there are belt tensioning devices. The extract motor is screwed to a mobile plate which moves via oblong holes in the motor bridge. This is used to tension the belt drive between the motors. It is possible to tilt the entire motor bridge with the use of the oblong holes on the wash motor side. This is used to tension the V-belt up the wash drum.

The motors are equipped with thermal protectors which are placed in the stator coil. In the case of overheating in the motors, i.e. if the temperature exceeds 130°, the protector contacts cut the power to the motor relays.

Supply injection valve

Construction

This valve has a single-inlet with three outlets, each with its own solenoid coil.

The body is made of heat-resistant polyamid plastic and the solenoids encased in water-tight plastic. The electrical connector terminals are spade lugs.

A filter screen on the inlet side prevents dirt from entering the valve. Flow restrictors can be placed at either the inlet or any of the outlets.

Operation

When the solenoid is energized, the springloaded plunger is drawn up and the pilot valve in the center of the diaphragm open. Because of the difference in diameter between the pilot valve opening and the ventilating hole in the diaphragm, the pressure above the diaphragm drops to a point where the admission pressure below the diaphragm can lift the diaphragm, thus opening the valve.

When the current to the solenoid is cut off, the plunger spring will press the plunger against the pilot opening of the diaphragm. The pressure above the diaphragm then rises to correspond to the water inlet pressure and the pressure of the spring will close the valve.

Repair instructions

Limescale can block the hole in the valve diaphragm and interfere with the function of the valve.

It is therefore advisable to dismantle and clean the valve at certain regular intervals. The frequency depends on operating conditions and the level of contamination in the water.

If the valve does not open

• Check that power is supplied to the coil.

• Check the coil with an instrument to determine whether there is a break or a short circuit.

• Dismantle the valve (see below) and check the openings in the valve diaphragm.

• Check the inlet strainer and clean as required.

• Undo the coil and clean the surfaces of the magnetic core.

If the valve does not close

• Check that the coil is not live. The valve is normally closed when the magnet is not energised.

• Check the return spring.

• Check the diaphragm (pilot pressure opening).

Dismantling the valve.

• Pull the coil stright upwards. Use a screwdriver if necessary to carefully undo the coil.

• Use the tool supplied (attached to one of the hoses when the machine is delivered) to open the valve housing. Slide the tool over the protruding plastic sleeve to that the pegs on the tool engage the corresponding sockets in the valve housing.

• Use a spanner or a pair of pliers and unscrew the upper part of the valve housing.

Inlet valve EX 22

The water inlets have brass bodies with a larger cross section of the outlet in order to acheive a shorter filling time for the machine.

Construction

The valve housing is made of pressed brass. The spring-loaded plunger is made of stainless steel and located at its lower end is a rubber gasket for the pilot valve.

Operation

The valve is automatically operated by means of a rubber diaphragm and a pilot valve in exactly the same way as the supply injector valve.

NOTE: To strip, clean, re-assemble and troubleshoot the inlet valve, follow the instructions outlined for the supply injector valve.

Clean out

At water temperatures of more than 60°C/140°F, the lime deposits are heavily increased. This can cause function problems due to blocking up the equalizing orifice of the valve.

The fault can be eliminated by cleaning the equalizing orifice (marked A).

If there are much deposits the orifice can be changed from 0.5 mm to 0.8 mm. The screwhead of the orifice is marked with 1 ring for the size of

0.5 mm and 2 rings for the size of 0.8 mm. Clean the orifice as follows:

1. Shut off the main supply.

2. Unscrew the orifice

3. Clean the hole in the orifice carefully with a pin or similar not thicker than 0.5 resp. 0.8 mm.

4. Mount the orifice, be careful with sealing and tighten.

5. Open the main supply.

Soap supply box

The three-compartment soap supply box is located at the top of the machine. Viewed from the front, the compartments are marked with figures 1, 2 and 3.

Compartment 1 and 2 are used for adding detergent directly to the wash. Compartment 3 is used for adding fabric softener. All three compartments can be programmed individually.

For liquid supplies compartment 2 is only used together with a top mounted supply injector connection. See page 9 for details and installation instructions.

Drain valve

Description

The drain valve consists of a bracket (1), on which are mounted the motor and gear (2) and diaphragm (3). The rubber diaphragm is resistant to a water temperature up to 100°C (212•F). The installation of a lint trap is not necessary. The machine is equipped with an overflow, which bypasses the drain valve. The drain can be cleaned by removing the drain connection (4) outside of the machine or by removing the rubber diaphragm (3). The motor and gear assembly is covered by a plate and provided with quickdisconnect electrical connections. The stator coil is constructed for continuous operation.

Operation

The drain valve is normally open, i.e. the motor does not close the valve until it receives current via a contact of the timer. As soon as the current is cut, the shaft turns and opens the diaphragm of the valve. This also permits the machine to drain, in the event of power failure. The overflow hose (5) leads excess water or suds directly to the waste line, in the event of failure in the inlet valves or level control.

Trouble-shooting

If the valve does not open or close properly:

1. Check that the shaft is moving freely.

2. Check that the diaphragm is not obstructed.

3. Check the coil for continuity.

Clean out

Periodic cleaning of the valve is recommended, depending upon how often the machines are used, as well as the type of wash handled most frequently.

General

The washing machine’s program operation is controlled by a microcomputer and the wash programs are stored in an electronic memory. Program controls are very exact and the wash programs can be easily adapted to the end user’s individual requirements.

The machine is supplied with a number of fixed basic programs which cannot be deleted or modified. However, they can be used as a background for programming end user programs. It is also possible to compose entirely new programs. 90 such programs can be stored in the program unit’s memory.

The following parts of the control panel are used when programming:

• the key switch which is used to switch the machine to the programming position.

• 13 push button switches which are used only for programming.

• the numeric keys which are used to enter different program data

• °C/°F press button to select the temperature scale (°Celsius/°Fahrenheit)

• display window where the programming steps are controlled with the aid of questions and selections.

Programming - general description

Programming can be divided into two programming principles: Programming a new program or using an old program as a background.

Programming a completely new program

The wash program is constructed by selecting different sub-programs with the buttons on the panel. These sub-programs, when stored after each other, form the complete final wash program. Sub-programs can be selected in an optional sequence.

A program can, for example, be built up in the following way:

• Pre-wash 1, Drain 1

• Main wash 1, Cool down 1, Drain 2

• Rinsing 1, Drain 3, Extract 1

• Rinsing 2, Drain 4

• Rinsing 3, Drain 5, Extract 2. When programming, a number of questions must

be answered for each sub-program. The questions are answered with the YES, NO buttons and the number keys.

When all sub-programs are programmed, any questions which apply to

the whole program must be answered. AN explanatory text can also be entered (this is displayed when PROG.INFO. is pressed after selection a program).

The last thing to be done is to store the program in the program memory under a vacant program number.

Programming

Fig.

Page 38

Using and old program as a background

In this operation, an old program is selected as a background for the new one. The answers to the questions and the written texts can be changed to create a new program. Furthermore, subprograms can be erased and new sub-programs entered in optional positions.

When the changes are complete, the new program is entered under a vacant program number. The program which was ’’borrowed’’ at the start of the programming is retained unchanged under its old program number.

The key switch

Turn the switch to the PROGRAM position if the wash program is to be programmed or changed.

If for any reason you wish to discontinue programming and start again, turn the switch to the RUN position and then back to PROGRAM again. Any programming that you have done so far will be deleted but other programs already stored will not be affected.

ENTER

An important principle when programming is that all commands (such as the choice of subprogram, answers to questions, text input) must be followed by ENTER.

The command can always be changed or deleted before ENTER is pressed.

EDIT UP and EDIT DOWN

The EDIT UP and EDIT DOWN buttons are used to go backwards or forwards in the program without its being affected, e.g. to go through the questions in a sub-program. The buttons are also used to enter program text (see under the heading ’’Entering text’’).

Answer YES and ENTER to the question ’’ERASE THIS MODULE’’.

• Deleting characters when entering text. To delete individual characters when

programming text, press ERASE. The last character you entered will disappear. (see under the heading ’’TEXT’’).

Selecting sub-programs

Press buttons PRE WASH, MAIN WASH, RINSE, DRAIN, EXTR. and COOL DOWN

designate different sub-programs and can be used to construct complete wash programs.

When necessary, the same sub-program can be used several times in the same wash program. Each sub-program is allocated its own number (e.g. RINSE 01, RINSE 02 etc.) so that the different sections can be easily identified.

Refilling

LEVEL RESET is value which regulates at which level water is to be refilled if the water level sinks while a wash is in progress.

Example: The following values are programmed:

• Level: 130 units

• Level reset: 10 units This means that:

• Water is filled to level 130 at the beginning of the sub-program. If the water level sinks below level 120 (130-10) during the course of the program, the water level is refilled to level

130.

• Select a level between 0-255. Values greater than the level value mean that no water will be added.

• The recommend value is 20 units.

Temperature

The water temperature can be programmed either in °C or °F. Use the °C/°F button to change between scales (note that the change is not displayed until the next change in the display window is made).

Temperatures can be selected within the range of 32-212°F (0-100°C) in stages of 1°.

Time

A sub-program can be timed in stages of 10 seconds. The longest time that can be programmed is 41 min. 40 sec (2500 seconds). The time does not include the time for water filling or heating.

NO to all three questions will cause the drum to be stationary.

Drain 1/Drain 2

These two questions need to be asked if the machine is fitted with an additional drain valve (e.g.) for recycling the rinse water). This determines the route the drain water takes.

The machine’s own drain valve opens automatically during the drain function.

Time

The emptying time can be programmed in stages of 10 seconds. The longest time that can be programmed is 41 minutes 40 seconds (2500 seconds).

Special cooling valve

Answer YES is there is a separate water valve use for cooling. If the answer is NO, the standard cold water inlet is used.

Gentle action

Answer YES if the machine is to operate on gentle action during cooling. The machine will operate on normal action if the answer is NO.

Times

Cold water is supplied in stages by the water valve opening and closing according to a particular pattern. The time for an opening or closing sequence is 30 seconds. This time is permanently programmed and cannot be changed. All that can be programmed is the ratio between open and closed valve.

The time the valve i open (ON time) can be programmed separately between 1 and 15 seconds. The valve is closed during the remaining time up to 30 seconds. The ON time is programmed separately within two temperature ranges: 212-158°F (100-70°C) and 158°F (70°C) — final temperature.

The rate of temperature reduction is monitored within the 212-158°F (100-70°C) range. If the ON time is selected so that the water temperature in the drum decreases by more than 7°F (4°C)/ minute, the valve is closed so that this value is not exceeded.

The final temperature can between 77-140°F (25-60°C) be programmed.
