Introduction

Introduction

Fig.

1

The EX 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 onpremises laundries where flexibility and quick formula variation, coupled with high quality automatic washing, are required.

The washer extractor is controlled by a programmable card which allow complete programming of temperatures, water levels, wash periods etc.

The machines are free-swinging, i.e., the drum is moveable and spring suspended in relation to the frame. This minimizes 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.

Mechanical and electrical design

General

Fig.

29

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.

29

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

Fig.

30

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.

30

The entire spring unit should be replaced in spring replacement.

Drum with bearings

Description

Fig.

31

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

Fig.

32

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.


It the coil does not lock the door:

• Check that the coil is receiving 100-110 V DC.

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.

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.

Rotation guard

Description

Fig.

34

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.

Relays

The EX 12 and 22 models employ eight relays.

Construction

Fig.

36

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

Fig.

37

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.

Fig.

38

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

Fig.

40

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

Fig.

41

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.

40

41

0306

0307



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

Fig.

42

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.

Fig.

43

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

Fig.

44

• 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

Fig.

45

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.

Fig.

45

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

Fig.

Fig.

47

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.

Drain valve

Description

Fig.

49

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.

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.

Card programming


General

Fig.

50

Programmable cards are used to regulate the different phases in a washing process. These are provided with a pattern of 16 ribs with pegs marked with the letters A-Q.

The cards are available in two sizes: 80 or 120 steps numbered from 0 upwards.

The program controls sense a step of 16 pegs across at one time. The card is fed forward by the program controls motor so that a new step is sensed. When the machine is filling with water or is heating the water, the program controls motor stops until the required level or temperature is reached.

If necessary, the program controls can be simply modified so that each step corresponds to one minute instead for 30 seconds.

Programming

Fig.

51

The principle applied to programming is to use a special pair of pliers to punch the pegs in the different stages. A peg that has been removed means that the corresponding function is activated when the program controls have fed that particular stage forward.

First mark the pegs you want to remove with a felt tip pen. Then make an additional check before you begin to punch the pegs.

• The program begins with step 0. Program the step before 0 in the same way as 0 to ensure a correct program start even though the card may be pushed too far into the controls.

• Program times

Fig.

55

Fig.

56

Each step in the program corresponds to

30 seconds.

The time for heating and filling with water shall not be included in the program time.

This also applies when water is added for cool down (rib P). The program control motor is stationary during these phases.

• Extraction

After the extraction has been in progress for about 70 seconds, the machine automatically changes to low speed extraction and then after 60 seconds go up to high speed extraction unless the LOW

SPEED EXTRACTION switch is pressed in.

The drum should be filled with water to high level before draining and extraction starts.

This is to ensure that the wash is effectively distributed around the drum.

Drain (rib D) must be programmed to last at least one minute (two program steps) before the extraction starts.

Drain shall be programmed during the entire extraction time and for at least

2,5 min afterward.

• Drain

The machine always operates at distribution speed when drain is in operation

The purpose of the trouble shooting guide is to facilitate the location and correction of the most common machine problems.

Before the top panel is removed, power to the machine is to be switched off at the main source or at the separate circuit breaker.

At each trouble shooting attempt, the plug in connectors of the control panel should be moved in and out in order to eliminate improper contact due to faulty connection.

Please note that this guide does not include all possibilities, but only those most likely to cause the symptoms listed.

In trouble-shooting electrical problems, always make certain to have the proper electrical schematic or wiring diagram at hand. Test for power using a V-O-M or similar meter on the AC voltage scale. Test for continuity with all electrical power off.
