3、 Biochemical cultivation environment

1. Power supply AC220V 50Hz;

2. Environmental temperature: 5 ℃ -35 ℃ (when the set temperature is ≤ 10 ℃, the environmental temperature is ≤ 28 ℃);

3. Relative humidity ≤ 80%;

4. There should be no strong vibrations or corrosive gases around the instrument;

5. The instrument should avoid direct sunlight and the influence of other cold and heat sources;

6. The instrument should be placed horizontally with at least 20 centimeters of clearance around it;

7. The instrument should be kept indoors with good ventilation and no severe dust.

4、 Biochemical cultivation technology parameters

a、 Internal parameter list

Long press the setting button for about 3 seconds, and the password prompt "LC" will appear. Use the up/down keys to change the password to "3", click the setting button, and enter the internal parameter setting state. Click the setting button to modify various parameters, then press and hold the setting button for 3 seconds to exit this state, and the parameters will be automatically saved. If no key is pressed within 30 seconds, it will automatically exit this state and the current parameters will not be saved.

Note: 1. In order to achieve the desired control effect, P can be modified appropriately (usually within the range of "10.0-20.0"), but usually no modification is required and the factory parameters can be used directly.

2. When there is a deviation in the temperature measurement value, it is usually sufficient to modify Pb without modifying PK.

3. The default parameters of this instrument cannot be modified unless there are significant requirements.

Check the ambient temperature

Long press the setting button for about 3 seconds, and the password prompt "LC" will appear. Use the up/down keys to change the password to "18", click the setting button to enter the view of the ambient temperature status, and then click the setting button to exit this state. If no key is pressed within 30 seconds, it will automatically exit this state and the current parameters will not be saved.

b、 Compressor working mode and defrosting related parameters

Long press the setting key for about 3 seconds, and the password prompt "LC" will appear. Use the add/subtract keys to change the password to "123",

Click the setting button to enter the compressor working mode and defrosting parameter status. Click the setting button to modify various parameters, then press and hold the setting button for 3 seconds to exit this state, and the parameters will be automatically saved. If no key is pressed within 30 seconds, it will automatically exit this state and the current parameters will not be saved.

Note: 1. The defrosting function is only available when the compressor is operating normally, while the defrosting function is not available when the compressor is operating in a disconnected state.

2. When dt1=0, it means that even when the compressor is normally open, there is no defrosting when the temperature setting value is ≤ 8.0.

3. When dt2=0, it means that even when the compressor is normally open, there is no defrosting when "8.0 ℃ ＜ temperature setting ≤ 15 ℃";

Notes:

A、 Compressor control mode

1. The instrument will automatically determine the working mode of the compressor after a 30 second power on delay. If the set value changes by no more than 3.0 ℃, the compressor will maintain its original working mode.

2. When the temperature setting value changes by more than 3.0 ℃, the controller will automatically determine how to operate. If the setting value changes by no more than 3.0 ℃, the compressor will maintain its original operating mode.

3. When the setting value of "S-H" changes, the controller must be powered on again for the "S-H" parameter to take effect.

B、 alarm function

When the controller is powered on * times or the temperature setting value decreases, even if "PV ≥ SP+AL", the alarm light does not light up and the buzzer does not sound.

C、 Temperature fault

If the temperature measurement value displays "0000", it indicates a temperature fault. Please check the sensor first. If the sensor is *, the controller is faulty.

6、 Usage method

1. Preparation before use

A、 Environmental temperature: 5-35 ℃; Relative humidity not exceeding 80%;

B、 There is no strong vibration source or strong electromagnetic field around;

C、 It should be placed indoors in a stable, level, and free from severe dust, direct sunlight, and corrosive gases;

D、 Adequate space gap (over 50 centimeters) should be reserved around the product;

E、 Product power supply voltage 220V 50Hz;

F、 Reasonably place and adjust the position and quantity of shelves. Items placed in the studio must be kept with a certain gap around to avoid air circulation obstruction.

2. Power on after startup

A、 Turn on the power switch, and the machine enters the running state after a self check process of about 4 seconds: the left screen (PV) displays the measured temperature, and the right screen (SV) displays the set temperature. The circulating fan is running and a whistling sound can be heard.

B、 Temperature setting and time setting

Press the "Set" button in the running state to enter the temperature setting state. The setting indicator light will turn on, the left screen will display SP, and the individual digits on the right screen will flash. At this time, the flashing position can be changed by using the shift key, and the flashing position value can be modified by using the up/down key. After the modification is completed, press the setting button again to confirm and enter the time setting state: the left screen displays ST, and the individual digits on the right screen flash (the operation method is the same as the temperature setting method). After the modification is completed, press the setting button to confirm and return to the running mode (timing is in minutes, if no time setting is needed, set ST to "0" and the machine will continue to work).

3. Application example: Temperature 30 ℃, constant temperature time 60 minutes

Click the setting button to enter the temperature setting state. Left screen: SP displayed, right screen digit flashing: press the up/down key to change the value to 30. Press the setting button again, the left screen will display ST, and the individual digits on the right screen will flash. Press the up/down button to change the value to 60. Press the setting button again to store data and exit the temperature and time setting state.

After running, the buzzer will sound for 30 seconds. Press and hold the decrease button for 4 seconds to restart the program. When the buzzer sounds, press any key to silence it.

7、 Temperature calibration

When the temperature displayed on the instrument does not match the measured temperature (measured after 2 hours of constant temperature on the machine), the following method can be used to calibrate the temperature: long press the setting button for about 3 seconds, LC will appear on the left screen, use the increase and decrease buttons to modify the value on the right screen to 3, and then click the setting button to enter the internal parameter state of the machine. Press the set button one by one to switch the internal parameters to Pb, and then modify their parameter values: Pb=actual temperature value - instrument measurement value (the adjustment process can refer to the "Internal Parameter List"). After modification, press and hold the setting key to return to the running state.
