——DCS正确停电——

第一步：进行断电前的各项检查 
1、打开控制站柜门，观察卡件是否工作正常，有无故障显示； 
2、从每个操作站实时监控的故障诊断中观察是否存在故障，并进行记录； 
3、检查电源箱是否工作正常，电源风扇是否工作，5V、24V指示灯是否正常，测量记录各电压值； 
4、备份组态、PID参数、驱动以及其他需要的重要数据； 
5、检查供电冗余，供电冗余包括交流供电冗余和直流供电冗余。交流供电冗余：通过分别断开冗余交流~220VAC进线的一路，系统有一半的交流供电回路失电，但系统应仍然可以正常工作。直流供电冗余测试方法如下： 
（1）先断一路电源箱电源，测量每一机笼机笼母板电源端子上5V、24V的电压； 
（2）先通上一路电源箱电源，再断另外一路电源箱电源，再测量每一机笼母板电源端子上5V、24V的电压。电源箱5V输出电压应在5.10V～5.25V之间，电源箱24V输出电压应在23.00V～25.00V之间。如果电压偏差较大需要及时检查处理，否则会影响卡件的正常工作。 
6、网线及布置检查，检查网络线缆通断情况，确认连接处是否接触良好，并及时更换故障线缆； 
7、UPS测试：通过断开UPS交流进线，测试UPS电池供电能力。UPS电池应定期放电，一般建议每月一次，放电方法：断开UPS交流供电采用电池供电，至电池即将释放完为止。 
　以上检查主要事先了解系统的运行状态，如有不正常的现象可以在停车时及时解决。 

第二步：按顺序切断电源 
1、每个操作站依次退出实时监控及操作系统后，关操作站工控机及显示器电源； 
2、逐个关控制站电源箱电源； 
3、关闭各个支路电源开关； 
4、关闭不间断电源（UPS）电源开关； 
5、关闭总电源开关。

——DCS correct power outage——

Step 1: Conduct various inspections before power outage

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

2. Observe and record the existence of faults from the real-time monitoring fault diagnosis of each operating station;

3. Check whether the power box works normally, whether the power fan works, whether the 5V and 24V indicators are normal, measure and record the voltage values;

4. Backup configuration, PID parameters, drivers, and other necessary important data;

5. Check the power supply redundancy, which includes AC power supply redundancy and DC power supply redundancy. AC power supply redundancy: By disconnecting one of the redundant AC~220VAC incoming lines, half of the AC power supply circuit of the system loses power, but the system should still be able to operate normally. The redundancy testing method for DC power supply is as follows:

(1) Firstly, disconnect one power supply box and measure the voltage of 5V and 24V on the power terminals of each cage and cage motherboard;

(2) First connect one power supply box, then disconnect the other power supply box, and then measure the voltage of 5V and 24V on the power terminals of each cage motherboard. The 5V output voltage of the power box should be between 5.10V and 5.25V, and the 24V output voltage of the power box should be between 23.00V and 25.00V. If the voltage deviation is large, it needs to be checked and handled in a timely manner, otherwise it will affect the normal operation of the card.

6. Check the network cable and layout, check the connection and disconnection of the network cable, confirm whether the connection is in good contact, and replace the faulty cable in a timely manner;

7. UPS test: Test the power supply capacity of the UPS battery by disconnecting the UPS AC incoming line. UPS batteries should be discharged regularly, generally recommended once a month. Discharge method: Disconnect UPS AC power supply and use battery power until the battery is about to be discharged.

The above checks mainly focus on understanding the operating status of the system in advance. If there are any abnormal phenomena, they can be promptly resolved during parking.

Step 2: Cut off the power supply in sequence

1. After each operation station exits the real-time monitoring and operating system in sequence, turn off the power supply of the industrial control computer and display of the operation station;

2. Turn off the power supply of the control station power box one by one;

3. Turn off the power switches of each branch;

4. Turn off the uninterruptible power supply (UPS) power switch;

5. Turn off the main power switch.
