              浙大中控DCS卡件某測點信號顯示故障應如何快速排除?

              DCS系統某測點信號(溫度、壓力或流量等)顯示故障應如何快速排除?
              How to quickly remove the display fault of DCS signal (temperature, pressure or flow, etc.)?
              信號顯示數據不準或無顯示是可能常遇到的問題,它可能由于現場儀表引起,也可能由于DCS引起,可采取快速判斷的方法有:
              Inaccurate or no display of signal data is a common problem. It may be caused by field instruments or DCS. The methods of quick judgment are as follows:
              1)用信號發生器模擬標準信號測試(前提是現場必須有信號發生器可使用)或將另一同類型信號線纜改接到該通道信號引入測試,若正常表明DCS正常,再檢查現場進DCS信號是否有誤。
              1) Use the signal generator to simulate the standard signal test (provided that there must be a signal generator available on site) or connect another signal cable of the same type to the channel for signal introduction test. If it is normal, it indicates that the DCS is normal, and then check whether the on-site DCS signal is wrong.

              2)檢查信號線正負是否接反、卡件跳線設置是否正確(特別是新增點),組態型號、量程、補償等參數設置是否有誤。
              2) Check whether the positive and negative of the signal line are connected reversely, whether the jumper setting of the card is correct (especially the new point), and whether the configuration model, range, compensation and other parameters are set incorrectly.
              3)檢查該信號所屬卡件其他測點運行是否正常,并根據現場實際情況判斷是否可采用對該卡件備件更換的方式檢測是否為卡件故障,更換時注意跳線設置。
              3) Check whether other measuring points of the card to which the signal belongs operate normally, and judge whether the card spare parts can be replaced according to the actual situation on site to detect whether it is card fault, and pay attention to the jumper setting when replacing.
