4.2.2LED

合闸LED指示灯：

当装置检测到断路器位置信号为合闸状态时，合闸LED指示灯将点亮，颜色为红色。

进行本地操作合闸时，在“操作预令”状态下该指示灯闪烁。

运行LED指示灯：

在装置正常工作时，为闪烁状态，颜色为绿色。

当运行LED指示灯不闪烁时，表明装置为非正常工作状态，应立即处理、维护。

故障LED指示灯：

当装置检测到其所监控的电力设备发生故障时，如线路短路、接地等，故障LED指示灯点亮，颜色为红色。

告警LED指示灯：

当装置检测到电力设备运行于不正常工作状态，如控制回路断线、过温等而发出的告警信号时，该指示灯点亮，颜色为红色，若检测到装置内部故障时该指示灯闪烁。

分闸LED指示灯：

当装置检测到断路位置信号为分闸状态时，分闸LED指示灯将点亮，颜色为绿色。

进行本地操作分闸时，在“操作预令”状态下该指示灯闪烁。
