五軸加工中心PCU50主機顯示二個88包修好故障處理：西門子PCU50-840D系統常見故障：開機黑屏、白屏;啟動不正常；死機無反應；供電不顯示；無法正常進入加工界面；H1、H2 的7段碼顯示“28”“69”“88”等。
西門子PCU5*現象：840D數控系統機床，的PCU50.3重新啟動時，計算機不能正常啟動，上電后數碼管顯示88 ，兩燈同時顯示紅色
西門子PCU5*分析：PCU無法啟動故障，說明內部調用時出現了問題。
故障排除方法：
1.重新啟動試機；
2．檢查外圍接口線路是否有松動或接觸不良；
3.檢查供電單元，正常輸入電壓是+24vdc；
4.打開PCU50.3單元，將PCU 后蓋打開，檢查內存條是否插牢靠，扁平電纜插接是否可靠； 
5.如果仍未檢查出故障，檢查西門子840D 的軟件系統HMI advanced，可以將以前備份好的系統備份重新鏡像到一個新的硬盤上做實驗。
6.后(hou)可以判斷PCU50.3的主板損壞，此時(shi)需要廠(chang)家或專(zhuan)業維修(xiu)公司(si)進(jin)行(xing)維修(xiu)。
