This situation is mostly brought on by irregular collection resistance welding of CLK, CI, and BO to the front and rear from the X chip, so just focus on checking these 6 resistors. There is a tiny chance that it's brought on by irregular welding of the next pins of your 3 chips X-one, X, and X+1:
d-one) The first scenario: the exam time is largely the same as The nice board (typically the value of X will never change each time you examination) (take a look at time refers back to the time from when the beginning exam button is pressed to the result of ASICNG: (X) displayed around the LCD). This situation is probably going being because of the abnormal resistance welding of the front and rear CLK, CI, and BO of your Xth chip, so buyers shall concentrate on these six resistors. The little chance is because of X-one, X, X+one, that is definitely, Amongst the 3 chips, the subsequent pins irregular welding disorders from the chip come about: Figure 5-sixteen d-2) The next scenario: the test time is nearly 2 times as long as the good board (from time to time the value of X will alter every time you check, and at times X=0); right now, the log generally has the next information and facts (the purple number is not really 13, according to which seat the hash board tester is linked to); during the test, think which the domain voltage of many of the fields before the irregular situation is nearly a lot less than 0.
In the situation of a certain chip becoming fastened, check for irregular resistance welding with the front and rear CLK, CI, and BO on the Xth chip. In the event the check time is sort of twice as long as The nice board, it may well suggest a difficulty with soldering.
(three) When changing the chip, it is necessary to plant tin within the pins from the chip to start with, and afterwards solder it on the hash board. Use heat-conducting gel evenly within the area in the chip and after that put in the massive heat sink.
The voltage of each and every voltage domain is about one.35V. If there is a 14V powering, there is mostly a site voltage, and also the output of the power terminal from the hash board is calculated 1st; if there is a 14V powering but no area voltage, keep on to check down.
Not long ago, many companies proclaiming to become mining providers imitate us and say that they're connected with us, or that they're our department businesses, that has triggered clients to generally be deceived.
a-3) Measure the resistance of R232 or R233 with a multimeter to check if it is in just one ohms plus the reading will likely not leap randomly. Otherwise, make sure you change these two resistors
Possibly, the IP cannot be located on account of irregular operation. Confer with the primary stage for troubleshooting.
Continue to research with dichotomy right until the problematic chip is located. Assuming that there's a difficulty with the Nth chip, if the 1V8 and RO among the N-1th and Nth chips are small-circuited, N-one chips can be found, but if the 1V8 and RO in between the Nth and N+1th chips are limited circuited, the whole chip can not be observed.
(two) U1 can not be made use of on other series of models If your OTP perform is enabled within the control board.
If the PIC sensor NG is exhibited within the LCD display with the hash board tester as well as exam study temperature is irregular, then Adhere to the upcoming ways to troubleshoot The difficulty.
This spare aspect is precisely created for simple servicing and repair in the S19 Professional hash board, making certain seamless functions and large-overall performance mining.
Verify if the conductive copper bar is in lousy Get in touch with, Check out if the power Manage wire is loose or ruined, and swap the facility provide.
● Following Buy Here the plan exam is handed (the small-circuit take a look at of the general program take a look at is important to stay away from the chip or other resources staying burnt mainly because of the shorter circuit when the ability is turned on), the chip examination could be performed with the hash board tester, and the positioning may be determined according to the exam results of the hash board tester. ● Based on the exhibited effects in the hash board tester detection, starting from near faulty chip, check the chip examination details (CO/NRST/RO/XIN/BI) and voltages for example VDD0V8 and VDD1V8. ● According to the sign circulation, aside from the RX signal, reversely transmit the signal (from No. 76 to No. one chip), a number of with the signals together with CLK CO BO RST are forward transmission (1-76), plus the irregular fault stage are available through the electricity source sequence.
