——DCS停電維修——

第三步：進行DCS停電維護
1、操作站、控制站停電吹掃檢修。包括工控機內部，控制站機籠、電源箱等部件的灰塵清理；
2、針對停電前檢查出的故障進行維護；
3、係統供電線路檢修。包括分電箱、端子排、繼電器、柵等。確保各部件工作正常、線路可靠連接；
4、接地係統檢修。包括端子檢查、各操作站（工控機、顯示器）接地檢查、各控制站（電源、機籠）接地檢查、對地電阻測試；
5、通信線路連接線、連接點檢查，確保各部件工作正常、線路可靠連接。做好雙重網絡線的標記。

——DCS正確上電——

第四步：現場以及DCS的各項維護工作完成後，檢查確認重新上電條件是否滿足。係統維護負責人確認條件具備後方可上電，係統總體上電按如下步驟進行：
1、首先合上配電箱的總斷路器，檢查輸出電壓是否符合220V±10%；
2、合上配電箱內的各支路斷路器，分別檢查輸出電壓；
3、若配有UPS或穩壓電源，請檢查UPS或穩壓電源輸出電壓是否正常，不正常則查找原因，恢復後才能繼續以下的控制站上電與操作站步驟。
第五步：控制站上電，DCS電源依次上電
第六步：操作站上電，操作站的顯示器、工控機等設備上電
第七步：進行DCS重新投運檢查
1、打開控制站櫃門，觀察卡件是否工作正常，有無故障顯示；
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，主要包括卡件故障及通訊故障提示等；
3、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，測量供電電壓是否正常；
4、檢查各層網絡通訊情況，組態運行情況，PID參數等。

——DCS power outage maintenance——

Step 3: Perform DCS power outage maintenance

1. Power outage, blowing and maintenance of the operation station and control station. Including dust cleaning of components such as industrial control computers, control station cages, and power boxes;

2. Maintain faults detected before power outage;

3. System power supply line maintenance. Including distribution boxes, terminal strips, relays, safety barriers, etc. Ensure that all components work properly and the wiring is reliably connected;

4. Maintenance of Earthing system. Including terminal inspection, grounding inspection of each operating station (industrial computer, display), grounding inspection of each control station (power supply, machine cage), and grounding resistance test;

5. Check the communication line connection lines and connection points to ensure that all components are working properly and the line is reliably connected. Mark the dual network cable.

——DCS is correctly powered on——

Step 4: After the maintenance work on site and DCS is completed, check and confirm whether the power on conditions are met. The system maintenance responsible person can only power on after confirming that the conditions are met. The overall power on of the system should be carried out as follows:

1. Firstly, close the main circuit breaker of the distribution box and check if the output voltage meets 220V ± 10%;

2. Close each branch circuit breaker in the distribution box and check the output voltage separately;

3. If UPS or regulated power supply is equipped, please check whether the output voltage of UPS or regulated power supply is normal. If it is abnormal, find out the reason, and then continue the following steps of control station power on and operation station after recovery.

Step 5: Power on the control station and DCS power supply in sequence

Step 6: Power on the operation station, and power on the display, industrial control computer, and other equipment of the operation station

Step 7: Conduct DCS re commissioning inspection

1. Open the control station cabinet door and observe if the card is working properly and if there are any fault displays;

2. Observe whether there are any faults from the real-time monitoring fault diagnosis of each operating station, mainly including card faults and communication fault prompts;

3. Whether the power box works normally, whether the power fan works, whether the 5V and 24V indicators are normal, and whether the measured power supply voltage is normal;

4. Check the communication status of each layer's network, configuration operation status, PID parameters, etc.
