ABB 3BHB002916R0001 UFC721AE在自动控制系统的设计中我们设计了故障显示报警系统，设置在控制现场各控制柜面板，用指示灯指示设备正常运行和故障情况，当设备正常运行时对应指示灯亮，当该设备运行有故障时指示灯以1Hz的频率闪烁。为防止指示灯灯泡损坏不能正确反映设备工作情况，专门设置了故障复位/灯测试按钮，系统运行任何时间持续按该按钮3s，所有指示灯应quan部点亮，如果这时有指示等不亮说明该指示灯已坏，应立即更换，改按钮复位后指示灯仍按原工作状态显示设备工作状态。

故障显示设置在中心控制室大屏幕监视器上，当设备出现故障时，有文字显示故障类型，工艺流程图上对应的设备闪烁，历史事件表中将记录该故障。故障显示设置在中心控制室信号箱内，当设备出现故障时，信号箱将用声、光报警方式提示工作人员，及时处理故障。

ABB 3BHB002916R0001 UFC721AE在处理故障时，又将故障进行分类，有些故障是要求系统停止运行的，但有些故障对系统工作影响不大，系统可带故障运行，故障可在运行中排除，这样就大大减少整个系统停止运行时间，提gao系统可靠性运行水平。

ABB 3BHB002916R0001 UFC721AE In the design of the automatic control system, we designed the fault display alarm system, which is set on the panel of each control cabinet in the control site. The indicator light is used to indicate the normal operation and fault of the equipment. When the equipment is in normal operation, the corresponding indicator lights up. When the device is faulty, the indicator blinks at a frequency of 1Hz. In order to prevent the lamp bulb damage can not correctly reflect the working condition of the equipment, specially set the fault reset/light test button, the system runs any time continue to press the button 3s, all the indicators should be quan department lit, if there is an indication such as not bright indicates that the indicator is broken, should be replaced immediately, after the button reset the indicator is still according to the original working state of the device display working status.

The fault display is set on the large screen monitor in the central control room. When the equipment fails, text displays the fault type, the corresponding equipment blinks on the process flow chart, and the fault is recorded in the historical event table. The fault display is set in the signal box in the central control room. When the equipment fails, the signal box will prompt the staff with acoustic and optical alarm to deal with the fault in time.

ABB 3BHB002916R0001 UFC721AE classifies faults when dealing with faults. Some faults require the system to stop running, but some faults have little impact on the system work. The system can run with faults, and the faults can be eliminated during operation, which greatly reduces the entire system stop running time. Improve the reliability operation level of gao system.
