Computer Board 1. The computer board consists of display board and main control board for close cooperation. 2. Basic parameters (for power):AC current 2.1. Rated voltage: 220~240V 2.2. Rated frequency: 50Hz as universal frequency 2.3. Rated power: 350W 2.4. Automatic voltage identification: With 2.5. Automatic frequency identification: With 2.6. The maximum operating load of controller: 500W 3. Safety certification requirements: CE certification, 3C certification 4.
Operation panel 1. Appearance: (Display panel and display board are shown in following figure.) 2. Key 2.1 Temperature up/down key: To press up/down key for temperature setting. 2.2 Setting key: To set functions and enquire the maximum and minimum refrigerator temperature. 2.3 Lighting switch key: To press lighting key so that lighting lamp is on. To press it again so that it is off. 2.
Peripheral Signal of Computer Board 1. System input quantity: A、 Temperature sensor: With ordinary refrigeration sensor in the refrigerator; B、 Key signal: Please refer to key definition for details. C、 Door switch signal: With door switch signal; Fan is connected when door body is closed and it is disconnected when door body is opened. Door switch is fitted with normally closed switch. That is, 2 terminals of switch are closed when opening the door body.
Function Control Display and Key Control 1. Display: 1.1 Refrigerator shall display actual temperature during initial power supply and after temperature reduces to the minimum value and before increasing to setting temperature which corresponds to such temperature gear. 1.2 Current actual temperature is ±2°C of setting temperature for gradual variation to setting temperature.
bootstrap point. There is no alarm if refrigerator temperature is within scope of alarm limit. There is instant temperature alarm and buzzer will ring if refrigerator temperature is out of control limit scope. Alarm lamp will flicker and alarm sound can be cancelled by pressing alarm key. However, alarm indicator lamp will keep flickering and it is off only when refrigerator temperature is within scope of alarm limit. 4. Temperature control 4.
and display refrigerator temperature again (without flickering) if there is no operation within 10 seconds. 4.5 Setting of Internal Parameters Several internal parameters can be adjusted by following method to guarantee normal operation of refrigerator: To press “regulate” key for more than 10 seconds to display original design value (rd) with flickering; To press “+” or “-” to adjust setting value. Adjustment scope is 1℃ to 4℃ because setting value can vary by 1℃ by pressing the key every time.
Form 1:Internal parameter form under control contents Internal parameter Parameter instructions Scope Default value Instructions /unit rd Adjustment gain is 1 for setting temperature difference 1~6 2 ℃ r1 Adjustment gain is 1 for the maximum setting temperature LE~20 8 ℃ 3 r2 Adjustment gain is 1 for the minimum setting temperature -40~HE 0 ℃ 4 c1 Press delay startup period during controller operation 0~10 0 min 5 c2 The minimum compressor shutdown period 0~10 5 min c3 Long
4.6 Inquiry of the Maximum and Minimum Refrigerator Temperature The maximum and minimum refrigerator temperature can be enquired by following way: The maximum or minimum temperature is actual temperature detected by sensor, not the maximum or minimum displayed temperature. Enquiry of the maximum value: In the meanwhile, users can press “SET” key and “+” to display the maximum actual value without flickering in the window. Please loosen any key to return to display refrigerator temperature.
key at the same time to show higher alarm limit in the window without flickering. It can return to refrigerator temperature display when loosening the key. Enquiry of lower alarm limit: To press alarm key and “-” key at the same time to show lower alarm limit in the window without flickering. It can return to refrigerator temperature display when loosening the key. 5.
9. Delay Protection Function Shutdown and bootstrap interval of compressor shall be not less than c2 minutes.
Trouble Display and Treatment Display temperature is “EE” for display board and it will flicker by frequency of 1Hz during trouble (such as short circuit or broken circuit) of temperature sensor. In the meanwhile, it will buzz and enter into protection mode for compressor operation control according to internal parameters dO and dF.
