FS450R17KE3/AGDR-71C是ABB公司生产的一款IGBT模块1。在日常维护中，它的主要任务包括更换丝和锂电池，基本没有其它易损元器件1。

日常维护

PLC的日常维护和保养比较简单，主要是更换丝和锂电池，基本没有其它易损元器件。由于存放用户程序的随机存储器（RAM）、计数器和具有保持功能的辅助继电器等均用锂电池保护，锂电池的寿命大约为5年，当锂电池的电压逐渐降低到一定程度时，PLC基本单元上电池电压跌落到指示灯亮，提示用户注意有锂电池所支持的程序还可保留一周左右，必须更换电池，这是日常维护的主要内容1。

I/O模块的更换

若需替换一个模块，用户应确认被安装的模块是同类型。有些I/O系统允许带电更换模块，而有些则需切断电源。若替换后可解决问题，但在一相对较短时间后又发生故障，那么用户应检查能产生电压的感性负载，也许需要从外部其电流尖峰。如果丝在更换后易被烧断，则有可能是模块的输出电流超限，或输出设备被短路1。
