帶道閘刷卡稱重自動汽車衡*樺川150T地磅

故障(zhang)排(pai)除：1)電(dian)吹風直(zhi)接吹干；

2）用酒精浸泡刷洗，吹(chui)干，清除表(biao)面污物(wu)；

3）原則上巳(si)被污濁的接線板應(ying)更換。

公司(si)50 t 電子汽車衡有時重車開上后顯示(shi)負超載(zai)，重新開機后有時能恢(hui)復(fu)正常，此現象經常發生。

故(gu)障分(fen)析：故(gu)障時(shi)(shi)有時(shi)(shi)無，估計不是(shi)(shi)儀表的(de)(de)原(yuan)因(yin)。檢查(cha)秤臺、連接件、限位都正常，排除機械(xie)方(fang)面原(yuan)因(yin)。把接線板上所有的(de)(de)焊(han)點重新檢查(cha)一遍，排除了虛焊(han)或脫焊(han)的(de)(de)可能(neng)(neng)。后用“替(ti)代法(fa)”和(he)“扯(che)線法(fa)”查(cha)出故(gu)障是(shi)(shi)由某個(ge)傳(chuan)感器(qi)引起(qi)的(de)(de)。經檢查(cha)確認有一個(ge)傳(chuan)感器(qi)的(de)(de)信號線被(bei)老鼠咬破，有時(shi)(shi)能(neng)(neng)接觸上，則儀表正常，有時(shi)(shi)則處(chu)于斷(duan)開狀態，儀表顯示負超載。

故障處理(li)：把此傳感器(qi)信號線從咬破皮處剪(jian)斷(duan)，用環氧樹脂處理(li)后，做(zuo)個接頭，汽(qi)車(che)衡恢復正常
