Verify The situation with the temperature sensor. The temperature sensor is all Positioned on the back again from the PCB, although the resistance is found about the front of the PCB.
When there is Untrue welding, it ought to be re-soldered. If there is hurt, it must be calculated whether the resistance worth is typical. Swap the corresponding factors abnormally, and Test the small board soldered on the PCB; the tiny board is demonstrated from the figure underneath.
HEX file to become programmed; the next stage: click "hook up" to connect Usually; the 3rd move: click on the "system" button, and following completion, simply click "validate" to prompt the verification to confirm the programming is successful.
(three) When changing the chip, it is necessary to plant tin around the pins from the chip initially, and afterwards solder it towards the hash board. Implement warmth-conducting gel evenly around the surface in the chip then set up the large warmth sink.
The voltage of every voltage domain is about one.35V. If there is a 14V powering, there is mostly a website voltage, and the output of the power terminal of your hash board is calculated to start with; if there is a 14V powering but no domain voltage, proceed to examine down.
B) Check out whether the four temperature sensors of U5，R216、R219、R220，U7，R221~R223，U8，R224~R226，U9，R229~R231 and also the matching resistance welding are irregular, the location of your temperature feeling is as revealed in Determine 4-4 and 5-13, the temperature sensor is all Situated on the back again from the PCB, the resistance is found on the front and back with the PCB, and whether or not the temperature sensor three.3V energy provide is standard;

Test the Liquid crystal display Display screen ASICNG by measuring Price Here the whole voltage with the measuring domain and Improve circuit.
For the duration of tests, it's assumed that the domain voltages of all domains in front of the irregular site are almost all lower than 0.3V, although the domain voltages of the next domains are Practically all greater than 0.
Referring into the test system document, the final troubles that arise are assembly course of action issues and Regulate board method difficulties. Popular issues incorporate the inability to detect the IP, irregular number of detected supporters, and abnormal detected chain.
Referring to your examination method doc, the final issues are assembly procedure complications and Regulate board method problems.
On top of that, these suggestions must also involve Directions on cleaning parts with authorised solvents such as isopropyl alcohol or distilled h2o, as well as how you can retailer elements faraway from Extraordinary temperatures and humidity degrees safely and securely. At last, consistently scheduled routine maintenance checks really should be completed every few months or a minimum of yearly to ensure the correct performing of all sections in the technique.
