                DCS斷電前需要進行哪些檢查?
                What checks should be carried out before the DCS is powered off?
                1、打開控制站柜門,觀察卡件是否工作正常,有無故障顯示;
                1. Open the cabinet door of control station and observe whether the card works normally and whether there is fault display;
                2、從每個操作站實時監控的故障診斷中觀察是否存在故障,并進行記錄;
                2. Observe whether there is a fault from the real-time monitoring fault diagnosis of each operation station, and record it;
                3、檢查電源箱是否工作正常,電源風扇是否工作,5V、24V指示燈是否正常,測量記錄各電壓值;
                3. Check whether the power box works normally, whether the power fan works, whether the 5V and 24V indicator lights are normal, and measure and record the voltage values;
                4、備份組態、PID參數、驅動以及其他需要的重要數據;
                4. Backup configuration, PID parameters, drive and other important data needed;
                5、檢查供電冗余,供電冗余包括交流供電冗余和直流供電冗余。交流供電冗余:通過分別斷開冗余交流~220VAC進線的一路,系統有一半的交流供電回路失電,但系統應仍然可以正常工作。直流供電冗余測試方法如下:
                5. Check the power supply redundancy, including AC power supply redundancy and DC power supply redundancy. AC power supply redundancy: by disconnecting one circuit of redundant AC ~ 220 VAC incoming lines, half of the AC power supply circuits of the system lose power, but the system should still be able to work normally. DC power supply redundancy test method is as follows:

               ?。?)先斷一路電源箱電源,測量每一機籠機籠母板電源端子上5V、24V的電壓;
                (1) First, cut off the power supply of one circuit power box, and measure the voltage of 5V and 24V on the power terminal of each cage cage motherboard;
               ?。?)先通上一路電源箱電源,再斷另外一路電源箱電源,再測量每一機籠母板電源端子上5V、24V的電壓。電源箱5V輸出電壓應在5.10V~5.25V之間,電源箱24V輸出電壓應在23.00V~25.00V之間。如果電壓偏差較大需要及時檢查處理,否則會影響卡件的正常工作。
                (2) First connect the power supply of one power box, then cut off the power supply of another power box, and then measure the voltage of 5V and 24V on the power terminal of each cage motherboard. The 5V output voltage of the power box should be between 5.10v and 5.25V, and the output voltage of the 24V power box should be between 23.00v and 25.00v. If the voltage deviation is large, it is necessary to check and deal with it in time, otherwise the normal operation of the card will be affected.
                6、網線及布置檢查,檢查網絡線纜通斷情況,確認連接處是否接觸良好,并及時更換故障線纜;
                6. Check the network cable and layout, check whether the network cable is in good contact, and replace the fault cable in time;
                7、UPS測試:通過斷開UPS交流進線,測試UPS電池供電能力。UPS電池應定期放電,一般建議每月一次,放電方法:斷開UPS交流供電采用電池供電,至電池即將釋放完為止。
                7. UPS test: test the power supply capacity of UPS battery by disconnecting the AC incoming line of ups. UPS battery should be discharged regularly, generally once a month. Discharge method: disconnect UPS AC power supply and use battery power supply until the battery is about to be released.
