PLC硬件故障
PLC的硬件故障較為直觀地就能發(fā)現(xiàn),維修的基本方法就是更換模塊。根據(jù)故障指示燈和故障現(xiàn)象判斷故障模塊是檢修的關(guān)鍵,盲目的更換會帶來不必要的損失。
(1)電源模塊故障。
一個工作正常的電源模塊,其上面的工作指示燈如“AC”、“24VDC”、“5VDC”、“BATT”等應(yīng)該是綠色長亮的,哪一個燈的顏色發(fā)生了變化或閃爍或熄滅就表示那一部分的電源有問題?!癆C”燈表示PLC的交流總電源,“AC”燈不亮?xí)r多半無工作電源,整個PLC停止。這時就應(yīng)該檢查電源保險絲是否熔斷,更換熔絲是應(yīng)用同規(guī)格同型號的保險絲,無同型號的進口熔絲時要用電流相同的快速熔絲代替。如重復(fù)燒保險絲說明電路板短路或損壞,更換整個電源。“5VDC”、“24VDC”燈熄滅表示無相應(yīng)的直流電源輸出,當電源偏差超出正常值5%時指示燈閃爍,此時雖然PLC仍能工作,但應(yīng)引起重視,必要時停機檢修。“BATT”變色燈是后備電源指示燈,綠色正常,黃色電量低,紅色故障。黃燈亮?xí)r就應(yīng)該更換后備電池,手冊規(guī)定兩到三年更換鋰電池一次,當紅燈亮?xí)r表示后備電源系統(tǒng)故障,也需要更換整個模塊。
