  中控卡件壓力信號異常是什麽原因?
  What is the cause of abnormal pressure signal of central control card?
  A:壓力信號出現滿量程情況,與實際不符。斷開卡件後麵的信號線正極,信號由滿量程變仍有8公斤左右壓力信號(量程為0-13公斤)。經現場觀察,該測點經過安全柵。將信號線短路,不過安全柵後,信號顯示正常。
  A: The pressure signal is in full range, which is inconsistent with the actual situation. Disconnect the positive pole of the signal line behind the card, and the signal changes from full scale to about 8kg pressure signal (the range is 0-13kg). Through field observation, the measuring point passes through the safety barrier. Short circuit the signal line, but after the safety barrier, the signal display is normal.
  初步判斷是安全柵出現問題。原因可能是同一組的信號,安全柵是共地的。當安全柵故障後,另一毫安信號耦合到該信號上來,造成信號的幹擾。
  The preliminary judgment is that there is a problem with the safety barrier. The reason may be the same group of signals, the safety barrier is common ground. When the safety barrier fails, another Ma signal is coupled to the signal, causing signal interference.

  熱電阻信號不準如何排查?
  How to check if the thermal resistance signal is inaccurate?
  A:首先,檢查熱電阻的組態,確認了組態中的熱電阻型號和實際的型號保持一致;其次,確保上下位機組態一致。然後,如果還是懷疑測溫有問題的話,可以測量現場熱電阻A和B之間的阻值為R1;B和C之間的阻值為R2。
  A: First of all, check the configuration of the thermal resistor to confirm that the model of the thermal resistor in the configuration is consistent with the actual model; secondly, ensure that the configuration of the upper and lower computer is consistent. Then, if it is still suspected that there is something wrong with the temperature measurement, the resistance between a and B can be measured as R1; the resistance between B and C is R2.
  根據3線製熱電阻的測溫原理,可以得到熱電阻的實際電阻值為R1-2R2。然後查表找出對應的溫度。然後用這個溫度和監控上的溫度再進行比較。如果出入較大,請更換卡件後再次嚐試。
  According to the temperature measurement principle of 3-wire thermistor, the actual resistance value of thermal resistor is r1-2r2. Then look up the table to find the corresponding temperature. Then compare it with the temperature on the monitor. If the difference is large, please replace the card and try again.
