Usually, You will find there's problem Using the connection involving the hash board as well as the Command board. Look at the cable to check out when there is an open circuit. Should the link is Alright, the user can check The only board PT2 to examine if it can pass the test. If it passes the examination, it might mainly be determined that the challenge is about the Command board. If your test fails, make use of the PT2 repair system to repair it. three) Abnormal temperature: Usually, It really is due to the temperature is significant. The PCB temperature set by our monitoring method simply cannot exceed ninety levels. If it exceeds ninety levels, the miner will alarm and fall short to work Commonly. It is generally due to substantial ambient temperature for the miner to not have the ability to work Generally. Abnormal followers operation may even bring about abnormal temperature. four) Cannot discover all of the chips (boot could be operated, even so the hash charge r is two/3 or one/3 of the conventional value). The amount of chips is not really plenty of: if the volume of chips is just not ample, you'll be able to make reference to PT2 for testing and repair. Determine 7-one 5) Right after operating for the stretch of time, there isn't any hashrate, the connection to the mining pool is interrupted, then Examine the network;
Repair technique: check the looks, measure the chip capacitor or resistance in entrance, typically It truly is a result of weak chip soldering or perhaps a chip capacitor, resistor detrimental or abnormal resistance;
(three) The RX (RI, RO) sign circulation way is from BM180 chip to BM1 chip, then returns to pin eight of your signal cable terminal by way of U1 and then returns into the control board;
3. In the event the 'PIC sensor NG' is exhibited about the Liquid crystal display display on the hash board tester and the tested temperature is irregular, then follow the techniques beneath to troubleshoot: A) Test whether or not the four resistors of R217, R218, C22 and C23 are welding abnormally, and Look at whether the welding of PIN of U5 is usual; B) Check whether or not the four temperature sensors of U5, R216, R219, R220, U7, R221~R223, U8, R224~R226, U9, R229~R231 plus the matching resistance welding are abnormal, The situation of your temperature feeling is as shown in Determine 4-four and five-13, the temperature sensor is all located on the back again in the PCB, the resistance is situated on the front and back of your PCB, and whether or not the temperature sensor 3.
8. When replacing a whole new chip, clean the pins and use solder paste making sure that the chip is coated with tin prior to soldering.
B) Look at whether or not 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 placement from the temperature perception is as proven in Determine 4-4 and five-13, the temperature sensor is all Positioned around the again in the PCB, the resistance is situated on the front and back of the PCB, and whether the temperature sensor 3.3V ability supply is usual;
Along with the cooling fan is at full speed. To use the chassis for heat dissipation, two hash boards should be positioned simultaneously to kind an air duct. The only-sided test of production should also ensure the development of an air duct (important).
Open MPLABIPE and choose system: PIC16F1704, simply click electric power to pick the power supply method, then click run. The initial step: find "file" to find the .HEX file being programmed; the second move: click on "link" to attach Typically; the 3rd move: click the "method" button, and right after completion, simply click "confirm" to prompt the verification to show the programming is successful.
Once the ambient temperature is too large, it is not hard to bring about the large-temperature defense mechanism of the miner. If you see the next data within the log, it ensures that the running temperature of your miner is simply too substantial.
Measure whether There is certainly output on the second pin of U3 along with the voltage is about 3.3V; if Certainly, remember to proceed to troubleshoot the issue; if there's no three.3V, be sure to Look at the link standing of your hashboard tester cable and the hashboard is Okay, and reprogram the PIC.
d-1) The first scenario: the test time is essentially similar to The great board (ordinarily the value of X will not likely modify each time you test) (test time refers back to the time from when the start check button is pressed to the result of ASICNG: (X) shown within the Liquid crystal display).
three. Following repairing, the hash board have to be analyzed greater than two moments to generally be Alright ahead of it may possibly go! four. Check whether the resources and hash board testers can perform normally, determine the maintenance station to test application parameters, exam fixture variations, etcetera. five. Within the examination of repairing and replacing the chip, the chip must be analyzed 1st, then the purpose take a look at shall be done soon after passing. The function examination have to make certain that the modest heat sink is welded capable. When installing the massive heat sink, the area with the chip has to be evenly coated with thermal gel as well as the cooling fan shall be at whole speed. When using the chassis to dissipate heat, 2 hash boards needs to be put simultaneously to type an air duct. 6. When measuring the signal, use four supporters as aid for heat dissipation, plus the followers shall manage total pace. 7. When powering over the hash board, the user have to first link the damaging copper wire of the ability source, then the optimistic copper wire of the ability source, And at last plug within the signal cable. When eliminating, the get of set up must be reversed. Very first, clear away the sign cable, then get rid of the good copper wire of the power provide, and finally eliminate the destructive copper wire of the power provide. In Look Here case the consumer does not comply with this order, it is vitally straightforward to cause harm to R8, R9, U1, U2 (not all chips can be found). Just before screening the pattern, the repaired hash board must be cooled down before screening, or else, it may well trigger PNG tests. 8. To exchange a whole new chip, printing pins and soldering paste are necessary making sure that the chip is pre-soldered and afterwards soldered on the PCBA for repair. III. hash board tester earning and matters needing notice The supporting fixture with the hash board tester must satisfy the heat dissipation of the hash board and facilitate the measurement of signals. 1. Use the 19 series hash board tester SD card swiping system for The 1st time to update the hash board tester Management board FPGA, unzip it and replica it on the SD card, after which insert the cardboard into your hash board tester card slot; electricity on for about 1 minute and anticipate the Command board indicator to double flash three instances, then the update is done; (if It's not up-to-date, it could bring about a certain chip for being terrible in the test). Determine three-one 2. Make the examination SD card In keeping with the necessities, and straight unzip the compressed package deal of the single-sided warmth sink inspection chip to make the SD card; Determine 3-two three. The take a look at SD card are going to be built according to the necessities, and the double-sided warmth sink 8-times patter take a look at really should make an SD card, as demonstrated while in the figure underneath;
If your serial port stops long-length managing once the short-circuit, it means the initial chip is Alright. As outlined by this technique, locate the chip that also fails following a long-length jogging after a chip small circuit. Usually, it can be brought on by a harmed chip, and you may exchange it;
a) Liquid crystal display Screen ASICNG: if (0), 1st measure the entire voltage from the measuring area and also the Improve circuit 19V is typical, then use the short-circuit probe to shorter-circuit the RO take a look at stage and also the 1V8 test issue between the very first and the 2nd chip, and after that operate the program to locate the chip.
