Control system memory

9.1.1

General structure of the memory system

The system features an EEPROM memory module, fitted externally to the microprocessor, which serves to
memorize the configuration data, the description of the cycle, the status of the appliance in the event of a power
failure, and the alarms.

9.1.2

FLASH

This area memory contains the firmware code relative to the functions of the appliance:
Control of electrical loads (motor, pump, solenoid valves etc.).
Control of the sensors (pressure switches, motor speed, door status etc.).
Control of the user interface
Control of the serial port
Control of power failure procedure and alarms
Execution of the washing programme
Power failure, i.e. the information necessary to restart the appliance in the event of a power failure:
Selected cycle and options
-
- Current phase and sub-phase
Machine status, used to perform special cycles such as:
- Electrical test (used in the assembly line)
- Continuous cycles (used in the factory workshop)
Machine configuration: the data contained in the EEPROM define the characteristics of the model and are
interpreted by the function software. The variables are as follows:
- Type of appliance (front-loader, top-loader, compact)
- Type of door interlock (PTC or instantaneous)
Anti-flooding safety device
-
Transmission ratio between drum pulley and motor pulley
-
Structure of the washing group
-
Power supply frequency (50/60 Hz)
-
Type of PCB (horizontal or vertical buttons)
-
Detergent drawer (3 or 4 compartments)
-
Final spin speed (600 – 1400 rpm)
-
Identification of the appliance:
Prod. N.
-
ELC
-
Serial number
-
Configuration of the user interface:
Programmes on main selector
-
Function of secondary selector (if featured)
-
Number and functions of buttons
-
- Functions of the LEDs
- Operation of the buzzer
