  • Page 20: Control Unit

    Mechanical and electrical design Control unit The control panel (1), mounted at the front, Fig. 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 microprocessor-controlled electronic timer is mounted just behind the control panel.
  • Page 21 Mechanical and electrical design Relays The HI-TEK model employs seven relays. The relays control: • the wash windings of the wash motor • the distribution windings of the wash motor • the extraction motor • the switching back to low speed extraction if too high unbalance is indicated.
  • Page 22 Mechanical and electrical design Drive motors Drive motor description The four-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 2-speed motor for extraction speeds (4-pole drive, low speed and 2-pole, high speed).
  • Page 23 Mechanical and electrical design Drive motor function When the stator winding is charged, a magnetic field will occur, which in turn will rotate the motor at a fixed RPM depending upon the number of poles in the winding. The 12-pole winding gives the wash speed and the 8-pole winding in the same motor gives the distribution speed.
