During reflow soldering heating process, the sudden alarm prompts "the temperature in a certain temperature zone is too low or the difference between a certain temperature zone and the set temperature is too large".+ V7 A6 V0 D$ t, ^0 D7 w0 R           In view of this phenomenon, we can preliminarily judge that the fault will appear in the heating or overheat protection part, so we short circuit all the overheat protection switches to make them invalid, and then start the machine and find that everything seems to be normal. After further analysis, we know that the machine can work when the overheat protection switch is short circuited, but in case of heating failure, when the temperature rises too high, there will be less protection line, which will bring more serious consequences+ W! q; u* r0 ? 6 j: [8 A5 _ 3 r0 G& I4 Y) B- Z. m# L2. If the reflow soldering machine is shut down for a long time, when it is restarted, the computer will prompt "communication failure" and the machine cannot be started for a long time for heating., y# }$ Y6 [$ n! Y         In view of this phenomenon, we initially suspected that it was a communication line fault, so we replaced the communication line. The problem still exists, so we denied this conjecture. After further observation, it is found that when the communication is not successful, the status light on the controller is abnormal, and the orange light should be flashing instead of going out. 2 A, R- f, B+ J    S- Y4 v7 m3 k, S" D# w2 S) s。。。。
