P0800EC-FOXBORO

开机无电压输出，整机无反应。可用万用表测量变压器线圈引出端的电阻或电压即可判断。测电阻时要断开并联在线圈两端的元件。测电压时，如果次级各线圈均无电压，但初级线圈两端有电压，说明初级线圈断路。如果次级只有某一线圈无电压，说明该组线圈已经断路。断路故障多为焊接点导线霉烂所致，多发生在引出线根部或绕制过程中漆包线头的焊接点。应仔细检查每个引出端与引脚的焊接点是否断路。如均无断路，则说明故障存在于线圈的内部，可用“刺探法”寻找断线部位。即用万用表的低阻挡，将一只表笔接绕组的一个引出线，另一只表笔捆上一根细缝衣针，刺接每层线圈***靠边缘的一匝，当刺到某一层后表粗无偏转时，即说明该层线圈已断路。
