若(ruo)出現主機(ji)起動(dong)前(qian)'允許起動(dong)'信(xin)號燈(deng)不(bu)亮故障，可能(neng)的原(yuan)因及相(xiang)應處理辦法(fa)有如下(xia)幾(ji)種：

1.指示燈壞了：更(geng)換(huan)

2.液溫超過60℃：等(deng)液溫降(jiang)至60℃以下(xia)(xia)，在進行下(xia)(xia)一步(bu)操(cao)作(zuo)

3.起動極(ji)未到(dao)起始位(wei)：用手動試車(che)或(huo)復位(wei)按(an)鈕調整傳動機構至正(zheng)常位(wei)；行程開關(guan)失靈，更換

4.下限行程開關(guan)為釋放：檢修或(huo)更換

5.液位過(guo)低：添加清水之液位上限(xian)位

6.傳動過載：檢查傳動機構運轉有無卡死，添(tian)加潤滑油并調整至靈活；復位傳動電(dian)機熱過載繼(ji)電(dian)器(qi)(qi)，并檢查熱過載繼(ji)電(dian)器(qi)(qi)整定值是否正確

7.繼電器(qi)換了：更換
