Programme unit
The programme unit is made up of the CPU card,
the display card, card reader and one or two I/O
cards. The programme unit holds a number of
standard programmes, but it is also possible to
programme user-specific washing programmes,
either using the control panel on the machine or
a computer.
The programme unit card reader is used to
transfer programmes between a computer and
the washing machine or between different
washing machines.
The programme unit communicates with the
motor control through a serial interface. One or
more I/O cards control the water valves, drain
and heating of the machine. The control signals
are sent via a communication card in the rear
control unit to the various components. The
communication card has connectors for
connecting to various external components, such
as detergent pumps or external water valves.
The programme unit of the machine is described
in detail in section 23. Programme unit.
