公司50 t 電子汽車衡(heng)有時重(zhong)車開上后顯示負超載(zai)，重(zhong)新(xin)開機后有時能恢復正常(chang)，此現(xian)象經常(chang)發生。

故(gu)障(zhang)分析：故(gu)障(zhang)時(shi)(shi)有時(shi)(shi)無，估計(ji)不(bu)是儀(yi)表(biao)的(de)原(yuan)因。檢查(cha)秤臺(tai)、連(lian)接(jie)件、限位都(dou)正常(chang)，排除機(ji)械(xie)方(fang)面(mian)原(yuan)因。把接(jie)線板(ban)上所有的(de)焊點重新檢查(cha)一遍，排除了虛焊或脫焊的(de)可能。后用“替代法”和(he)“扯線法”查(cha)出故(gu)障(zhang)是由某個傳感器引起的(de)。經(jing)檢查(cha)確認(ren)有一個傳感器的(de)信號線被老鼠咬(yao)破，有時(shi)(shi)能接(jie)觸(chu)上，則(ze)儀(yi)表(biao)正常(chang)，有時(shi)(shi)則(ze)處于斷開狀態，儀(yi)表(biao)顯(xian)示負超載(zai)。

故障處(chu)理：把此傳感器(qi)信號線從咬破(po)皮處(chu)剪斷，用環氧樹(shu)脂處(chu)理后，做個接頭，汽車衡(heng)恢復正常
