Control System Overview - Block Diagram

Operations

General Description of Basic Operation

The control system includes the control board, wiring harness, power cord, light bulb,

compressor motor & NTC sensor.

The control board manages the on/off cycles of the compressor motor.

The control board monitors also the ambient sensor.

The light bulb is controlled by mechanical switch. There is no AC feedback input in the

control board.

Operations

Service State

Service State

This state is engaged when the Service technician interacts with the appliance in order to check if it is working

properly or not. During the firsts 30sec after the product energizing, independently of any other consideration, the

system will search for the Service Password.

The „Service‟ state will be engaged when:

1. Set-point == Eco

2. The Service technician presses and hold for 5sec the temperature setting push button SW1

Service state functional behavior

After entering in „Service‟ state, the compressor load & the LED3 (Jet Freezing (yellow)), LED2 (green), LED1 (green)

will be turned OFF.

The LED4 (Alarm (red)) will be forced ON.

The Service technician will use the temperature setting push button SW1 (waiting at least 3sec since the „Service‟

mode activation) to advance the steps of the „Service‟ state mode in order to evaluate the loads behavior and the

LED‟s/push button functionality. The LED‟s will be turned ON/OFF according to the following sequence:

Operations

Service State

End of „Service‟ Mode:

· When reached the last step (5), press the temperature setting push button SW1 once more to

show test results

· Time-out of service State: 10min

Operations

Fail Message state

Test result:

When service test is finished, result can be:

· PASS

Conditions:

· End service mode by end service & temperature sensor is OK

System Action:

· All LED‟s ON for 1sec. then all LED‟s OFF for 1 sec. then the default set point engage

NOT PASS

Conditions:

- Temperature sensor fails or timeout

Service State FAIL:

· Transition 1: done automatically after 2s from the current state start

· Transition 2: performed after SW1 becomes pressed

· Transition 3: done automatically after 2sec from the current state start

· Immediately after entering the „Power up‟ state, the default set point will be restored

FAIL Message state:

In case of a sensor defect, all LED‟s will blink.

Operations

Check Software version, Service Bit Alarm Code routine

User action:

· During the first step of the service test routine, press the temperature setting push button SW1 for 5sec

System Action:

· show the software version, Service bit information and the Alarms information as described below:

Transition Action:

· Transitions 1 to 3 occur when the user presses the button SW1

End System Action:

· After transition 3 return to ‘Service’ routine, step 2

Operations

Software version state

System Action:

· Show the software version according to the table below:

Operations

Service Bit state

System Action:

· show the ‘Service’ bit state according to the table below:

Service routine completed:

· All points of previous service test have been done.

Service Mode not finalized or end service by time-out:

· Time-out of previous service State: 10min

Operations

Alarm Information state

System Action:

· Show last alarm stored into non-volatile memory.

Just one alarm will be saved into the non-volatile memory and shown through the User Interface

following the indication as defined in the table below.

NOTE:

Immediately after Test Procedure engagement, the default start conditions shall be restored in the

not volatile memory in order to have the DEFAULT parameters configuration at next power up.

Fast Freezing compressor runs continuously 50 hours

Jet Freezing compressor runs continuously 6 hours

Sensor failure mode:

If the sensor becomes unreliable, the compressor will be time driven

· 15min OFF

· 45min ON

until the failure condition disappears.

Operations

Alarms

Over temperature Alarm

This alarm will provide a warning signal to the user if a dangerous Over temperature has been achieved during the

normal operation mode due to whatever causes (door not closed, damaged gasket, etc.).

Alarms priorities

Here below the alarms priorities:

1. Sensor failure

2. Over temperature alarm

Over temperature alarm shall be activated if (T > -8°C) since at least 30min. this condition does not apply at the plug in.

It is turned automatically off if (T < -9°C).

If the over temperature alarm becomes engaged:

· LED4 will blink

If the over temperature alarm becomes disengaged:

· LED4 will stop blinking

Over temperature alarm status will be saved in the non volatile memory only if:

T > -8°C AND Product_On > PRODUCT_TIME_ON (6h)
