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…)
9.1.3 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 diagnostic mode
Ö
Select a cycle and options, and start the cycle
