  • Page 18: Mechanical And Electrical Design

    Mechanical and electrical design General The door, cycle indicator, coin meter or manual start switches, indicator light and program-selection knob are located at the front of the machine. All control and indicating components, i.e. relays, level control, cycle timer, etc are assembled under the top cover, easily accessible from the top of the machine for simplified servicing.

  • Page 19: Machine Construction

    Mechanical and electrical design Machine construction Outer shell The outer shell is made of heavy gauge surgical steel and is attached to a heavy Fig. duty, rigid head casting (back gable). The whole assembly is mounted on a heavy gauge fabricated steel base, galvanized for long life and corrosion resistance.
  • Page 20 A grease seal is mounted to prevent escape of grease. The bearings are permanently lubricated and need no maintenance. Wascomat's design transfers the weight of the loaded wash cylinder to the largest possible surface area away from the bearings, for longest machine life.

  • Page 21: Control Unit

    Mechanical and electrical design Control unit Fig. The cycle timer (K51), rotary program selector (S5), level controls (B1 and B2) and rotation guard (B31) are mounted just behind the control panel. The relays (K1-4) are located at the top of the machine, easily accessible for service.
  • Page 22 Mechanical and electrical design Relays The W245 employs four relays to control the Fig. motor speeds: • wash speed (K1 and K2) • distribution speed (K3) • extract speed (K4) Construction The body of the relay holding the stationary Fig. contacts is made of current-resistant plastic.
  • Page 23 Mechanical and electrical design Drive motor description The three-speed operation of the wash cylinder is Fig. achieved by two motors. One 2-speed motor for wash speed (12-pole drive) and distribution speed (8-pole drive) and one single speed motor for extraction speed (4-pole drive). The motors are mounted on a motor bracket, the extract motor fixed the bracket, the wash and distribution motor in slots which allow adjusting the distance...

Extract motor: 1, 2 and 3: extract speed (4-pole winding).
  • Page 25 Mechanical and electrical design How to remove motors Loosen the spring loads set screw. Lift the motor Fig. unit and detach the V-belts. Dismount the bracket holding the motor hinge shaft. Lift out the motor bracket with motors mounted. Loosen the mounting screws of the wash/distribution motor and the set screws.
  • Page 26 Mechanical and electrical design Description The machine door lock consists of the following: Fig. • The locking unit, located behind the front panel below the detergent dispenser. The unit consists of a solenoid which locks the door, and two microswitches. Switch S4A indicates that the door is locked and switch S3 indicates that the door is closed.
  • Page 27 Mechanical and electrical design Door lock control unit The sole function of this control unit is to oversee the correct functioning of Fig. the door lock. The CPU board receives information from the motor control unit about motor rotation, and has its own level-monitoring device. The control unit also detects water level and motor speed through separate level measurement devices and the rotation guard (speed-monitoring device).
  • Page 28 Mechanical and electrical design Error indication patterns Fig. If the door lock is working correctly, this is indicated by the red LED, by a pattern of flashes which indicates “OK”. The error indication patterns revealed by the LED flash at various frequencies for the various errors or faults.
  • Page 29 Mechanical and electrical design Inlet valve, detergent Construction The valve has a single-inlet with either one, two Fig. or 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.

  • Page 30: Troubleshooting

    Mechanical and electrical design Maintenance instructions Limescale can block the hole in the valve diaph- ragm and interfere with the function of the valve. It is therefore advisable to dismantle and clean Fig. the valve at certain regular intervals. The fre- quency depends on operating conditions and the level of contamination in the water.

  • Page 31: Inlet Valves
