  解決方式是將兩個控制器的模式選擇開關都扳到STOP位置,然后將先前沒有扳起來的CPU1模式選擇開關扳到RUN位置待RUN綠燈亮,STOP黃燈滅后,再將CPU模式選擇開關扳到RUN位置,RUN綠燈閃爍后滅,STOP黃燈一直亮,故障無法排除。系統下電前有一輸入變量被強制,現在FRCE(強制)黃燈亮,將該輸入點的強制取消(兩CPU),FRCE黃燈滅后,再次將狀態為STOP的CPU 0模式選擇開關直流電機西門子調速器6RA70報警F004修理從 RU NSTOP-RUN位置依次扳動,CPU0 RUN綠燈亮,STOP則黃燈滅,這時兩CPU都為RUN綠燈,REDF(冗余故障)和EXTF(外部故障)燈都滅,故障得以排除。擠壓(ya)機控制系統冗余故障(zhang)表現是(shi)巡(xun)檢時兩CPU上的 RED F和EXTF紅(hong)燈亮(liang)(liang) ,IFM2F紅(hong)燈亮(liang)(liang);熱備CPU1狀態為STOP黃燈亮(liang)(liang),CPU1中FM2(同步子模(mo)塊)LINKOK燈(deng)(deng)滅,控制器上其它狀(zhuang)態(tai)(tai)指示(shi)燈(deng)(deng)和故(gu)障(zhang)(zhang)(zhang)指示(shi)燈(deng)(deng)正(zheng)常。這種(zhong)狀(zhuang)態(tai)(tai)可初步(bu)判(pan)斷為同步(bu)模(mo)塊故(gu)障(zhang)(zhang)(zhang)造成冗余故(gu)障(zhang)(zhang)(zhang),引起外部故(gu)障(zhang)(zhang)(zhang)燈(deng)(deng)亮。
