1.3 Instruction(application ,working principle, technical parameters)

Application

Series BCAJ-200 series carbon dioxide incubator is an advanced instrument for cell, tissue and bacterial culture, which is a key equipment necessary for immunology, oncology, genetics and bioengineering. Used in microbiology, medicine, pharmaceutical, environmental protection, food, animal husbandry and other scientific fields of research and production. It is an artificial environment for the growth and reproduction of microorganisms and cells, bacteria and viruses caused by artificial methods in the incubator, such as controlling a certain temperature, humidity, gas, etc., mainly used for tissue culture and the culture of some special microorganisms.
Compared with the water jacket type, the air jacket type has the characteristics of fast heating and rapid temperature recovery than the water jacket type incubator, which is especially conducive to short-term culture and the culture requiring frequent opening and closing of the box door.
Performance
The carbon dioxide incubator is improved on the basis of ordinary culture, mainly to add CO2 and humidity to meet the environment required for the culture of microorganisms.
Control of carbon dioxide gas concentration. It's done with a carbon dioxide concentration sensor. The carbon dioxide sensor is used to detect the concentration of carbon dioxide in the box, the test results are transmitted to the control circuit and the solenoid valve and other control devices, if the concentration of carbon dioxide in the box is detected to be low, the solenoid valve is opened, and the carbon dioxide enters the box until the concentration of carbon dioxide reaches the set concentration, at this time the solenoid valve is closed, the carbon dioxide in the box is cut off, and the stable state is reached.
The equipment is an air jacket type heating, the principle is through the carbon fiber heating wire all over the outer wall of the box air jacket direct heating inside the box, also called six side direct heating

6.5 User management

The user can enter[User Management] to set the user's password with three levels of authority. The user with administrator authority has all authorities except for system settings. The user with tester authority can select modes and set parameters. The operator authority can only access historical data.

7. Alarm and security features

- Temperature sensor fault alarm: The screen displays: -- words, indicating that the temperature sensor or controller itself is faulty.
- Temperature upper limit alarm: When the measuring temperature exceeds the set temperature by 1 degree, the heating will stop working, and the instrument alarm lamp will light up and the alarm sound will ring continuously.

7.1 Routine using and maintenance

please keep upright when moving this equipment
Do not frequently modify the set values during process, to avoid overload because compressor starts frequently , or it will affect life of use
When adding water, please use pure or distilled water, and do not use tap water or other unclean water sources.
The equipment is equipped with power switch and circuit breaker ,if there is something wrong with this equipment during process, please cut off the power and check the control circuit , and then check the other parts. (See wiring diagram)
Be sure to close the door tightly. If the door is not fully closed, the equipment cannot work normally. When closing the door, please pay attention to the door handle should be lifted up to open, do not exert too much force to damage the door lock mechanism.
Do not use corrosive solution to wipe the exterior surfaces in order to maintain the appearance of the equipment, keep the chamber clean, use a dry cloth or alcohol to wipe.
If set the equipment aside, keep the chamber dry, and cut off the power supply.
In order to ensure the uniform temperature in the box, the items in the box should not be placed too close and evenly distributed during the experiment, so as to facilitate the air transfer of the items in the box.
Do not touch, impact the inner wall of the box preheating chamber, careful heating temperature will cause damage.
Do not lean against the glass door or put incorrect pressure on it, which may cause injury to personnel.
Do not lean on the equipment to prevent injury or equipment damage caused by equipment tipping over or door damage.
If the equipment fails, it should be repaired by professional personnel or contact the sales department of the factory.

7.2 Optional using

RS-232/RS-485 instructions for use of the converter
- In order to proceed with data communication between the different standard serial interface to the computer, an external device or smart instrument, must provide conversion of standard serial interface. The converter is compatible with RS-232, RS-485 standard, capable of converting single-ended RS-232 signal to a balanced differential RS-485 signals.(it can connect 16 controller of this series together at the same time)



Trouble shooting
- Data communication failure
(1)Check if RS-232 port inside connection is correct.
(2)Check if RS-485 port inside connection is correct.
(3)Check if port is connected.
- Data is missing or incorrect
Please check if data communication equipment rate and format is accordance.

8. Trouble shooting

Trouble shooting	handling
Sensor fault indication (－ － －)	·The temperature sensor is abnormal. Check whether the temperature sensor is in good condition. Model PT100。
The temperature does not rise to the set value	·Check whether the display is heated. If it is heated, the electric heating wire is damaged or the control board or circuit is faulty.
Slow temperature rise	·Open the outer door to check whether the fan in the box is running. If the fan is not running, check the fault according to the wiring diagram.
CO2 concentration does not reach the set value	·Whether the external CO2 gas cylinder valve is opened and the CO2 gas cylinder pressure is normal (not less than 3Kg); · The intake control solenoid valve is faulty. Please check the fault according to the wiring diagram
No display	· Check whether the incoming plug wire has AC220V; · Check whether the power switch is on; · Check whether the power switch of the equipment is tripping. If it is tripping, please check the fault according to the wiring diagram.
