GTOP two-time smart light incubator manual

I. Overview

GTOP intelligent light incubator is controlled by a computer. It has four functions of biological culture test equipment, including illumination, hot and cold constant temperature, day and night automatic switching program control and over temperature protection. And optional multi-stage programming controller, computer control functions, liquid crystal display and other functions. It can be used as a test for seed germination, nursery, cultivation of microorganisms, feeding of insects and small animals.

The light box is designed according to the "International Seed Inspection Regulations of 1993", and is produced in accordance with the relevant requirements of the national industry standard JB/T6823 "Technical conditions of biological artificial weather box". As long as the daylight (light) experience time and temperature are set separately, and the night (no light) experience time and temperature are set separately, the computer will operate in accordance with the cycle of the program. If there is a power outage during operation, the time will be automatically recharged after power is restored.

In view of the fact that some intelligent lightbox products on the market are easily lost and controlled, the computer controller of this lightbox adopts effective measures on both hardware and software, including over-temperature protection, thermal resistance open circuit protection, thermal resistance open circuit protection, and compressors. Delay protection and many other protection features make this lightbox highly reliable.

The box of the light box is well-produced, has a beautiful appearance, and has good sealing. The inner layer adopts a three-layer hollow glass structure, so its heat insulation performance is good. With excellent computer controllers and sufficient cooling capacity, the actual performance of this lightbox is much better than that of the national industry standard.

The two sides of the top cover are respectively equipped with fluorescent sockets, and the studio has three insulating glass structures. The left and right sides are three layers of insulating glass. The cooling and heating are under the working room. The left and right sides are respectively connected with the outlets of the studio ventilation passages. Equipped with an evaporator, electric heater and two circulating fans to provide heating or cooling to the studio. The bottom chamber is equipped with compressors, condensers, cooling fans, instrument entry junction boxes and fuses.

I. Key Function

Illustrated from left to right (Figure 1)

Lighting This key is the lighting key of the cabinet. When the illumination is 0, press this button to turn on the light, and then press the button to turn off the light.

In the operating state, hold down the "lighting button", about 3 seconds later, enter the system parameter setting state, the time window shows Addr (refers to the communication address, can be ignored in the absence of communication), the temperature window shows the value; then press The query button is set, the time window shows tc (temperature correction), and the temperature window displays the measured temperature correction value. The user can modify it according to the actual situation through the plus and minus keys under the temperature window. Press the Set Query button again to exit the system parameter setting. At the factory, the parameters are generally set to: Addr=1, tc=0.0.

Set inquiry This key is set/search key. Press this key to enter the setting state of the climate box. The time indication window, temperature indication window and humidity lightness indication window number will start flashing. The daytime indicator light will be on. Press the corresponding â–² key to set the parameters for the daytime operation. Press the key again. Set the night running parameter, and then press this key again to return to the running working state. The setting is successful.

Day/Night This key is a day/night switch that is valid during runtime. Used to restart day or night work.

â–² for plus, minus keys. Pressing this key under the setting status can add 1, subtract 1 operation. If you press and hold for 2 seconds, you can add or subtract continuously. In the operating state, press 1 minus 1 to add or subtract the current time. If the time is reduced to 0, it will automatically enter another operating state. Press 2 plus 2 to display the current set temperature.

II. Indication window

The indicator window indicates the settings and run-time parameters

The cycle indicator window indicates the current running cycle. When the number of cycles exceeds 9, the decimal point lights up to represent ten digits. When the number of cycles exceeds 19, the decimal point blinks to represent the unitary bit. When the number of cycles is 30, 0 and the decimal point flash at the same time. .

The cycle indicator window indicates the time of setting and operation. The running time is counted by the countdown method. The unit is hour-minute.

The temperature indication window indicates the set and operating temperature in degrees Celsius.

The humidity/light indication window indicates the set and operating humidity or illuminance in units of %RH, percentage. The illuminance of 33% indicates that one set of lights is on; 66% indicates that the two sets of lights are on; Hi indicates that all lights are on.

III. Operation method example

Users request to set the time of day 12 hours, temperature 20 °C, light intensity 66%, night time 12 hours, temperature 10

°C, illuminance 0.

step 1. After powering on the tc, press and hold the lighting key first. After about 3 seconds, the Addr is displayed in the time window. The incubator enters the system setting, and then clicks the setting query button. The time window shows tc. The temperature window shows the temperature correction value. According to the actual situation through the temperature window under the plus, minus keys to modify. Press the setup query button again to exit the system setup state and enter the operating state. Before leaving the factory, the system parameters are generally set to Addr=1, tc=0.0.

2. Set search key, each display window number flashes, daytime indicator light, this time can set the daytime operation parameters: press 1 plus 1 key to set the control time, until the time indication window shows "12"; press plus 2 minus 2 key to set Temperature, until the temperature indicator window shows "20" °C; press 3 plus 3 button to set the illuminance, until the indicator window shows "66%."

3. Press the setting query button again to enter the night setting. The night indicator is on. The setting procedure is similar to step 1.

4. Press the setting query button again, the setting is completed, the operation state is returned to, and the incubator runs cyclically according to the set parameters.

V. Wiring diagram

Sixth, protection function

1. Short circuit of thermal resistance, open circuit protection: When the thermal resistance is short circuit or open circuit, the temperature indicator window displays “Err”, and the incubator will automatically stop heating or cooling.

2, over-temperature protection: When the measured temperature exceeds 53 °C, the automatic stop heating.

Seven, simple troubleshooting

malfunction

the reason

malfunction

the reason

Most of the lamp pins are not aligned or loose, and they may be damaged electronic ballasts or lamps.

Eight, use precautions

1. In the light box handling city, the dip angle shall not be greater than 45°C to avoid damage to the refrigerator.

2. Avoid violent shocks and impacts to avoid cracking the glass door wall.

3. The light box should be kept away from sources of electromagnetic interference and should be grounded to the earth ground of the outlet supplying the light box.

4. The space on the left and right sides of the studio is the air duct. Do not occupy the air duct when putting the objects on it to avoid uneven ventilation caused by poor ventilation.

5. Beware of debris falling into the cooling and heating room below the studio through the entrance and exit of the air duct in the studio, so as not to block the drainage holes and allow the water in the storage room to freeze.

6. In the summer season, when the temperature in the cabinet is not lower than 5°C, the temperature difference between the inside and the outside of the cabinet may be too large. It may happen that the evaporator in the cooling and heating room is frozen. Therefore, the ventilation of the laboratory and the outside must be protected. air conditioning.
