關于電(dian)(dian)器部(bu)(bu)(bu)分(fen)(fen)(fen)(fen)的(de)故(gu)(gu)(gu)障(zhang)(zhang)及處(chu)理，在檢(jian)修機(ji)器之前，先根(gen)據(ju)故(gu)(gu)(gu)障(zhang)(zhang)現(xian)象，判斷(duan)此故(gu)(gu)(gu)障(zhang)(zhang)是因為電(dian)(dian)器元(yuan)件(jian)的(de)故(gu)(gu)(gu)障(zhang)(zhang)還(huan)是液壓(ya)故(gu)(gu)(gu)障(zhang)(zhang)引(yin)起的(de)，然后再(zai)(zai)進(jin)行(xing)進(jin)一步(bu)的(de)測(ce)試。電(dian)(dian)器故(gu)(gu)(gu)障(zhang)(zhang)先判斷(duan)是因為輸(shu)入(ru)(ru)部(bu)(bu)(bu)分(fen)(fen)(fen)(fen)還(huan)是輸(shu)出(chu)(chu)部(bu)(bu)(bu)分(fen)(fen)(fen)(fen)引(yin)起的(de)。如果(guo)輸(shu)入(ru)(ru)部(bu)(bu)(bu)分(fen)(fen)(fen)(fen)與輸(shu)出(chu)(chu)部(bu)(bu)(bu)分(fen)(fen)(fen)(fen)都完好，再(zai)(zai)進(jin)一步(bu)判斷(duan)主機(ji)板哪一部(bu)(bu)(bu)分(fen)(fen)(fen)(fen)出(chu)(chu)現(xian)問題。在檢(jian)查(cha)(cha)電(dian)(dian)器故(gu)(gu)(gu)障(zhang)(zhang)時，應先檢(jian)查(cha)(cha)是否(fou)有(you)短路現(xian)象，電(dian)(dian)源電(dian)(dian)壓(ya)(其中(zhong)包括 INPUT及OUTPUT)是否(fou)正常(chang)。主機(ji)板：負責(ze)整個控(kong)制系統的(de)數據(ju)、處(chu)理、接受外部(bu)(bu)(bu)的(de)輸(shu)入(ru)(ru)信號...
