Operation

Long Black Out Alarm Algorithm

Long black out check will be executed each power up only if the algorithm is enabled.

This alarm signal show a dangerous over temperature for goods (safety preservation limit).

It has been achieved during a main power failure.

This alarm will be activated:

- after a main power restoring if the appliance was in the ON condition when the black out occurred.

The electronic control must check the Freezer NTC temperature and activate the alarm if the

value inside the cavity has risen above - 8°C (-7,5°C or more) during the black out period.

That means that the temperature value at black out occurrence must be recorded and compared with the

temperature value at the moment of power restoring.

This alarm will perform the following operations:

a) display the highest temperature value (blinking) detected at the moment of main power restoring

b) the Alarm state icon for LCD and red LED for 7-segment will be send to the User Interface ;

Operation

Thermostatic function

The thermostatic function must control the unit to

keep the compartments temperature values set by the

user on the Control Panel.

Compressor, compressor fan, evaporator fan and

damper control is performed using the temperature

values measured through the 2 NTC sensors of the

unit. The evaporator is equipped with a defrost

heater. The cold airflow in the refrigerator

compartment is regulated opening or closing an

electrical damper.

The thermostatic function must be suspended during

a defrost procedure, it will be resumed after the

defrost end.

Main Control Board description

The Main Board is located in the compressor area and communicate to the User Interface board.

The Main Control Board is installed on Side by Side appliances with In Door Ice Ice- Maker system (current Ice-

Maker) or NOT IDI Ice-Maker system (Ice-Maker Sankyo).

The product is a two compartments (refrigerator and freezer), one compressor automatic defrost appliance.

The main function of electronics is to manage the temperature inside the cavities and to manage the Ice and

Water dispenser controlling consequently the compressor and the other components operations.

The electronic control architecture is as follow:

7-segment IDI/NO IDI Biruni

LCD AKO-DIEHL

7-segment AKO-DIEHL

Main Board “Flextronics” to be

combined with the following User board


NTC senor in the refrigerator compartment

ON CONDITIONS:

When the fridge NTC sensor temperature is equal or higher than the ON value

corresponding to the user setting the following operation must be performed:

- The damper must be driven in OPEN position

- The evaporator fan must be switched ON

One NTC sensor is provided in the refrigerator compartment to control the temperature by means of the

evaporator fan and the damper. The Refrigerator Control Table defines the ON/OFF temperature values for

every possible user setting.

OFF CONDITIONS:

When the fridge NTC sensor temperature is equal or lower than the OFF value


- The damper must be driven in CLOSE position

- The evaporator fan must be switched OFF unless the compressor is running

in order to cool the freezer section.

Damper control

An electrical AC motor is used to close and open the air door. The motor when supplied rounds always in the

same direction. By means of a cam the air door is driven alternatively in open and close position. A signal is

returned to feedback the position of the air door.

The feedback is generated by means of a switch. During the motor running, when the air door reaches the

close position the switch contacts go from close to open status (no feedback at all).

The switch contacts go from open to close status when the air door is completely opened (220Vac Line

feedback).

The control shall detect the voltage rising and falling edge feedback.

The rising edge indicates the air door is completely opened. The falling edge indicates the air door is

completely closed. If control doesn‟t detect any feedback after 90 seconds from the motor damper

activation, the damper alarm will be set, the alarm will be showed only for 10 minutes since power up.

Note: At every power-up a 25 minutes timer will be set in order to perform a complete damper cycle, to avoid

that the sliding part of the damper will be blocked by ice formation (to guarantee a proper work).

When the freezer NTC sensor temperature is equal or higher than the ON value


- The compressor must be switched ON

- The evaporator fan must be switched ON

OFF CONDITIONS

When the freezer NTC sensor temperature is equal or lower than the OFF value


- The compressor must be switched OFF

- The evaporator fan must be switched OFF unless the

refrigerator compartment requires to be cooled.

One NTC sensor is provided in the freezer compartment to control the temperature by means of the compressor

and the evaporator fan.

The Freezer Control Table defines the ON/OFF temperature values for every possible user setting.

See on the next slide for the different version.


NTC senor in the freezer compartment


NTC sensor failure management

Freezer Compartment:

The following emergency procedure must be performed if the freezer temperature sensor became

unreliable:

Compressor, Compressor fan (1 minute delay since compressor starting) and Evaporator fan (3 minutes

delay since compressor starting) will be driven constantly till the emergency will recover.

No change will be implemented for refrigerator compartment algorithm and defrost operation.

The freezer probe is defect, if the resistance value is higher than 110 Kohm or lower than 500 ohm.

Refrigerator Compartment:

The following emergency procedure must be performed if the Refrigerator temperature sensor became

unreliable:

Damper and Evaporator fan shall cycle 15 minutes ON (Damper open and Evaporator run) and 30 minutes

OFF constantly till the emergency will recover.


Ice-water valve

For Value Line & IDI 2008 (both Biruni User Interface):

The water shaft activation will be detected by the User Interface and

then it will be communicated to the Main Board for Water valve

activation.

The control will calculate and record the total volume of water flowed

through the valve during the opening periods.

The flow rate for the dispenser water valve is:

1,51 liters per minute

(24 – 58 cc per seconds)


Ice maker water valve

The icemaker water valve will be automatically controlled and

driven by the icemaker system itself (current Ice-Maker) or by the

control board (Ice-Maker Sankyo).

The control will monitor the usage of the valve then calculate and

record the total volume of water flowed through the valve during

the opening periods.

The flow rate for the icemaker water valve is:

1,13 liters per minute

(140cc per 7.5 seconds +11cc –17cc)


Ice-maker

Ice-Maker ON / OFF manager (IDI Sankyo):

The Ice-Maker system works by itself, it means that the Main Board will just switch ON the relay K002 (for IDI

only) to give the system the power according to the customer user request, moreover the Main Board will detect

the Ice valve activation in order to update the Water Filter Indication counter.

To avoid water overflow, due for example to Ice-Maker wrong functioning, the Main Board will switch OFF

the relay K002 if the ice valve feedback lasts more than 20 seconds.

The Ice-maker system will be switched OFF till the following points will be satisfied:

1) the power has been removed (Power-OFF)

2) the main power has been re-applied (Power-UP)

During this failure condition the Main Board will send the alarm code to the User Interface


Dispenser lamp

According to product model a dispenser light can be attached to the User Interface board.

Dispenser light will be turned on while a paddle is pressed, turned off when all paddles are released.

When "child lock" function is active the dispenser light shall not be turned on even if a paddle is pressed.



According to product model a step motor can be attached to

the User Interface board.

Main Control board will communicate the action that step

motor has to perform (open, close).

The User Interface board generate the corresponding signal

to drive the motor in the required position.

To open or close completely the ice chute the step motor

needs to be driven for at least:

2.6 seconds: for close to open transition;

2.0 seconds: for open to close transition.

It is a low voltage 12Vdc stepper motor and it works as common stepper motor.

1. At every Power up it will perform an initialization (complete OPEN ad CLOSE movement).

2) At every paddle pressure it will open to allow the ice to be dispensed.

3) Releasing the paddle will cause the ice door to close.

There is a safety logic algorithm that allow to filter someone playing with paddle . I mean if you press and release

fastly the paddle the ice door will stay open. It will close 10 seconds later the last release. Of course that's

means every time you press the paddle the ice door will close 10 seconds later you release the paddle.

Note: If the power supply you remove the plug while it is closing or opening it will stop immediately because of no

power and you can have a half open ice door when appliance is not powered.



A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation

into a large number of steps. The motor's position can be controlled precisely, without any feedback

mechanism.

Stepper motors operate differently from normal DC motors, which rotate when voltage is applied to their

terminals. Stepper motors, on the other hand, effectively have multiple "toothed" electromagnets arranged

around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit,

such as a micro controller. To make the motor shaft turn, first one electromagnet is given power, which makes

the gear's teeth magnetically attracted to the electromagnet's teeth. When the gear's teeth are thus aligned to

the first electromagnet, they are slightly offset from the next electromagnet. So when the next electromagnet

is turned on and the first is turned off, the gear rotates slightly to align with the next one, and from there the

process is repeated. Each of those slight rotations is called a "step," with an integral (complete number)

number of steps making a full rotation. In that way, the motor can be turned by a precise angle.

Stepper motor characteristics:


Dispenser heater

According to product model, one or two heater can be

attached to the User Interface board.

Heaters state will be set according to what communicated

by the Main Control board (User Interface board is not

provided with EEPROM so the heaters state will be stored

by Main Control board in case of a main power failure and

communicate when power is restored).

The state of the heaters can be toggled between on or off

pressing the virtual button 2.

No heaters state feedback is foreseen.

Heaters must always be turned off when other loads are

turned on (dispenser light and/or step motor) and during

the start up procedure, i.e. the heaters will be turned on

after 10 seconds and anyway after the initial start up of the

stepper motor has finished.

Heater default state will be set to ON when the system

start.


Dispenser paddles

According to product model (with dispenser or not) one or two paddles (mechanical or electronic) can be

attached to the User Interface board. These paddles will act as extra buttons.

Their state has to be communicate to the Main Control board through the dedicated data foreseen in the

communication protocol. When the "child lock" function is active even these paddle are locked.

CODE TYPE DESCRIPTION

UU Compatibility failure User Interface board does not recognize the code sent by Main

Control board.

LF Board failure User Interface Board did not pass the factory test.

Between both boards (Main Board and User Interface) there will be performed a

compatibility check (communication between the boards). If the Main Board receive a not

recognized code (not specified code), the freezer compartments display show the listed

failure code and no other operations will be accepted, because in case of failure all the loads

will be turned OFF.

Board self test

Troubleshooting

The User Interface Board turns ON all LEDs for 3 seconds after each plug-in.

This allow a visual verification that all the LEDs are properly working.

The User Interface board itself can not recognize any failure at this stage.

During this time no operations will be allowed. (e.g. button pressure, function engagements)

Example : „0“ is

standing for

everything is ok!

All the error codes will be displayed on the fridge display. Every check have the related error code,

that shall be the same as the sequence number foreseen during the test.

If 2 or more error codes have been recognized, these codes shall be displayed on the fridge display

in a rolling way. Each code shall persist about 1 seconds till the „Built-In“ test will be stopped.

!

For all Side by Side appliance range 2008 is the same Test routine for the main board and user

interface like last year available. The Built-In test allows the technician to check important

components which are listed in the following tables.

Step 1: If the appliance was plugged in for longer than 15 minutes, disconnect it from the

power socket, wait 40 seconds and plug it in again.

Step 2: Wait till the User Interface finish the bootstrap ( only LCD version ).

Step 3: Open the freezer door

Step 4: Press the freezer light switch 3 times within 10 seconds.

Step 5: The test should be activated and on the freezer display you can see the code „00“

For de-activation of the test procedure, disconnect the appliance from the power or repeat the step 4.
