Ö Washing cycle tables: Each washing cycle consists of a series of phases (steps); the steps are the basic
instructions which comprise the description of the cycle, which is common to all appliances having the same
characteristics:
- Water fill
- Motor movement
- Reset
- Heating
- Drain
- Spin
- “IF” conditions (options, temperatures etc.)
Ö Configuration of the washing cycle: for each family of appliances, certain parameters associated with the
washing programme are defined:
- Operational limits (voltage/frequency)
- Transmission ratios
- Parameters for control of the signal from the tachometric generator
- Parameters for half-range operation of the motor
- Structure of the washing group
- Control parameters for the FUCS anti-unbalancing system
- Water fill control algorithm
- Alarm control system
- Sensor parameters (flowmeter etc…)
10.1.3 RAM
The RAM (Random-Access Memory) contains the variables, i.e. all the dynamic information used during
execution of the programme:
Ö Motor speed
Ö Water temperature
Ö Alarms
Ö Cycle selected
Ö Machine status
The RAM is cancelled when the power supply is disconnected (power failure or appliance switched off).
The contents of the RAM can be read using a computer connected via a DAAS interface.
The same system can be used to send commands to the electronic control unit such as:
Ö Select remote control mode
Ö Action the various loads in remote mode
Ö Select diagnostics mode
Ö Select a cycle and options, and start the cycle
