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.

Functional characteristics
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).

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.
Functional characteristics
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)
Functional characteristics
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)
Functional characteristics
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
Functional characteristics
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.
Functional characteristics
Dispenser stepper motor
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.
Functional characteristics
Dispenser stepper motor
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:
Functional 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.
Functional characteristics
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.
