7 Operations Control System Overview - Block Diagram

8 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.

9 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:

10 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

11 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.

12 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

13 Operations Software version state System Action: Show the software version according to the table below:

14 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

15 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.

16 Operations Temperature selection

17 Operations Compressor management SET POINT Compressor Start Compressor Stop Timer ECO -13,1 C -13,3 C Normal -14,9 C -15,1 C Intensive -16,7 C -16,9 C 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.

18 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.). 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) Alarms priorities Here below the alarms priorities: 1. Sensor failure 2. Over temperature alarm
