ENV 06 Electronic Boards

This presentation describes and explains thefunctionality of the ENV 06 electronic boards forwashing machines.

As shown in the pages before, the structure and the ranges of the new washing machines and tumble dryers are comparable.

That means this presentation can also be understood for tumble dryers in the same way.

Electrical Components In ENV 06Washing Machines

Following the already well known electrical components forthe new washing machine range.

37

Traditional Door Lock With PTC

•When the washing program is started by pressing the START/PAUSE button, the bi-metal PTC (contacts 3-5) is powered by the triac on the PCB: after 2 – 4 seconds, this closes the switch (5-4) which powers the electrical components of the appliance (only if the door is closed).• At the end of the washing program, the PCB disconnects the interlock from the power supply, but the door remains locked for 1 to 2 minutes (PTC cooling time).

38

IDOLO – Door Lock

2-3 approx. 1.2 kΩ2-4 approx. 1.0 kΩ3-4 approx. 200 Ω

39

NTC – Temperature Sensor

The NTC-sensor is identical to the NTC-sensor assembled in EWM 1000 and EWM 2000

temperature thresholds:cotton cycle:heating off : T>85°Cheating on: T<80°Csynthetic cycle:heating off : T>69°Cheating on: T<65°C

40

Elektronic Pressure Sensor

The electronic pressure sensor is an analogue device that controls the water level in the drum. A changing frequency signal will show the amount of waterin the drum to the main board.

41

Elektronic Pressure Sensor

Water load pressure in the watercircuit, which moves the diaphragm.Position of core (5) changes frequency of oscillator is changed.Main board measures the fre-quency and determines the amount of Water in the drum.

Inverter - Motor

Introduction of INVERTER motor control and asynchronous motor

Motor control by MAGNETEK

Max. power 1KW

2 poles Asynchronous motor

by CESET (55mm stack)

51

Inverter – Motor

Asynchronous 3 phases motor with tacho generator

- no protector in motor windings (self protected cause whenone phase is broken, motor will not work anymore)

- motor temperature lower compared to other AC motors- motor speed will be controlled by frequency - motor has no brushes longer lifetime

52

Inverter Motor

Capacitor

53

Inverter - Motor

For changing the speed the frequency will be changed higher or lower.The motor speed will be controlled by the tachometric generator (T).

54

Inverter - Motor

The 3 phases power is fed by the inverter electronic to the connectors on themotor. The phase shift is 120 degrees and peak amplitude is 310V.

55

Service Mode

Activation:

1. Cancel the set programeand switch the appliance off.

2. Press START/PAUSE and the nearest button simultaneously and switch the program selector to firstposition clockwise.

3. Hold the START/PAUSE and option buttons pressed till DIAGNOSTIC MODE appears or till the LEDsstart flashing (about 5 seconds).

To exit the service cycle switch the applianceoff, on and then off again.

Standard key combination

63

Service Mode

In this 1st selector position starts the User Interface test cycle; all LED (LCD) are lighted on sequentially, and pressing any key the correspondent LED (LCD) is lighted on.

Moving in clockwise direction, for any position there is a different test:Position 1: User interface test cyclePosition 2: Water load from wash compartment.Position 3: Water load from prewash compartment.Position 4: Water load from softner compartment.Position 5: Water load from 3rd valve.Position 6: Wash heater activation.Position 7: Spin phase at 250 rpm with water in the tub

(leakage test).Position 8: Drain and spin phase at max. spin speed.Position 9: Drum positioning (for top-loaders).Position 10: Last alarm display and possible reset. (New: last 3

alarms are saved in alarm memory)

64

Service Mode

Important information for service!!!

If time to end display is available, then

-temperature

-drum speed

-water level

will be shown during the service mode tests.

65

Alarm Management In User Mode

1. Buzzer sounds for alarms which are shown to the customer only (E10, E20, E40, EF0, excepted EB0)

2. Buzzer sounds with a specific sequence of three short beepsabout every 20 seconds (for TC1 – appliances a special jingle will be played for warnings)

3. In case of alarm the red Start/Pause – LED flashes as long as the fault condition is present (0,5s on, 0,5s off)

4. For TC1 appliances with graphic LCD display the warnings will be shown as text messages

66

Alarm Management in User Mode

Fast alarm reading is possible like in the presentwashing machine range by pressing the standard key combination about 2 seconds.

67

Alarm Management In Service Mode

1. Turn the programme selector to the alarm memory position

2. Red and green LEDs integrated in Start/Pause key flash alternated according to alarmn code:- Red LED shows the alarm family code (E42 4 times)- Green LED shows the alarm number (E42 2 times)

3. Alarm will be shown completely in time to end display, if LCDdisplay available (example: E42)

4. For graphic LCD user interfaces (TC1) a specific customer screen with complete alarm code and possible supplemen-tary text descriptions can be shown

5. Delete the alarm memory by pressing standard key combination

68

Alarm - Management in Service Mode

Attention:

It´s possible to read the last three alarm codes in the alarm memory by pressing a key combination simultaneously.

( Solution still under development )

69

Alarm Table

The creation of the new alarm table is still in development.

It can be found in the new service manuals for the ENV06

washing machine models when available.

In general the alarm codes are the same like in the current

ranges.

Some failure codes will be deleted and some new alarms will

be added.
