The vacuum system provides excellent pore impregnation in a compact form. As a result, edge retention is improved and refined samples are supported during grinding and polishing. Compression installation is the preferred method for achieving the best edge retention and highest throughput. Provides compression mounting systems and mounting compounds designed to meet the different needs of different laboratories Manual Mounting Machine,Hardness Inspection Metallographic,Mounting Press Equipment,Cold Mounting Sample Preparation TROJAN (Suzhou) Technology Co., Ltd. , https://www.troolymaterial.com
1, check the scene:
1.1. Determine the location of the SALE machine.
1.2, determine the computer's installation location.
2, preparation of materials:
2.1. Prepare the communication line according to the distance between the computer and the rice machine (usually more communication lines).
2.2. The computer is best to use a newly purchased computer. If the customer insists on using the original computer, please do a good job (refer to 1.1 in the installation process for details).
Second, the sale of rice machine installation process:
1, the computer's installation:
1.1. Connect the chassis of the computer with a wire (usually connect the ground wire to the water pipe).
2, bus installation:
According to the site survey situation, the bus is well arranged. The requirements for the bus are as follows:
2.1. Please check the shortness of the bus before installation. It should be normal under normal circumstances.
2.2, the longest distance of the bus is 1000m.
2.3. The layout of the bus can be curved, but engineers should try to make the distance of the bus shorter.
2.4. After the bus is installed, short the four ends of one end of the bus, that is to open the four heads of the bus and then put the four heads together. Use a multimeter to measure shortness, which should be normal under normal circumstances.
2.5. Ground the shield of the bus. (The housing of the shielded cable and the computer must be grounded before the rice cooker is powered on.)
2.6. Connect the yellow, black, blue, and red wires of the bus to A, B, Y, and Z on the transponder.
2.7. At the end of the bus, the optoelectronic repeater does not need to add 120 ohm resistors.
(Special Explanation: 120 ohm resistors are required for ordinary transponders)
3, the sale of rice machine installation :
Connect the rice cooker to the bus. The connection requirements are as follows:
3.1. Open a 5cm mouth from the nearest place where the rice-selling machine is to be installed. Remove the skin (note that the shielded wire must not be cut short), and then pull the signal line out to remove the skin. Solder it with soldering iron.
3.2, according to the above method will be sold in succession, the sale of rice machine must pay attention to is: After installing 3 machines to sell meals online, to see if the 3 machines are communicating properly, if normal Continue to connect, still follow the above method every three machines to detect once to install all the machines.
3.3. The connection between each machine and the bus must not exceed 1.5 meters. The communication line reserved for our machine is 1.5 meters.
Third, testing and problem solving:
Question 1 : Turn on the machine to sell food if the machine fails
Solution 1 : Check if the connection between the SALE Module and the bus is correct. If it is correct, replace the SALE Module.
Question 2: Individual machines fail
Solution 2: Check if the machine is connected to the bus correctly. If it is still not working, replace the machine.
Question 3: Some machines fail to connect several machines that are not connected.
Remedy 3: Replace the nearest uncommunicable machine from the computer to troubleshoot the problem.
Question 4: The speed of the swiping machine is slow.
Solution 4: A. Check if the end resistance of the bus is 120 ohms. If it is not 120 ohms, replace it with a 120 ohm problem. B. Whether the computer leaks electricity or not interferes with communication.
