RAC3.1-150-460-A0S-W1-220系統(tǒng)使用者自身進行的日常維護,維護人員應(yīng)對系統(tǒng)維護技術(shù)難度和可操作性有一定的認(rèn)識,了解應(yīng)具備的維護工具,明確哪些工作能自己完成,做到心中 有數(shù),出現(xiàn)問題要及時制定可行的維護方案。對DCS系統(tǒng)故障維護的關(guān)鍵是快速、準(zhǔn)確地判斷出故障點的位置，故障維護中的一些經(jīng)驗總結(jié)如下下幾點：
1) DCS系統(tǒng)往往具有豐富的自診斷功能。RAC3.1-150-460-A0S-W1-220根據(jù)報警,可以直接找到故障點,并且還可通過報警的消除來驗證維修結(jié)果。
2) 通信接頭接觸不良會引起通信故障,確認(rèn)通信接頭接觸不良后,可以利用工具重做接頭;通信線破損應(yīng)及時更換。
3) RAC3.1-150-460-A0S-W1-220某個卡件故障燈閃爍或者卡件上全部數(shù)據(jù)都為零,可能的原因是組態(tài)信息有錯、卡件處于備用狀態(tài)而冗余端子連接線未接、卡件本身故障、該槽位沒有組態(tài)信息等。
4) 當(dāng)某一生產(chǎn)狀態(tài)異常或報警時,我們可以先找到反映此狀態(tài)的儀表,然后順著信號向上傳遞的方向,用儀器逐一檢查信號的正誤,直到查出故障所在。
5) 當(dāng)出現(xiàn)較大規(guī)模的硬件故障時，最大的可能是由于DCS系統(tǒng)環(huán)境維護不力而造成的系統(tǒng)運故障，除當(dāng)時采取緊急備件更換和系統(tǒng)清掃工作外，還要及時和廠家取得聯(lián)系，由廠家專業(yè)技術(shù)支持工程師進一步確認(rèn)和排除故障。
RAC3.1-150-460-A0S-W1-220對于DCS系統(tǒng)的維護工作,關(guān)鍵是要做到預(yù)防第一,作為系統(tǒng)維護人員應(yīng)根據(jù)系統(tǒng)配置和生產(chǎn)設(shè)備控制情況,制定科學(xué)、合理、可行的維護策略和方式方 法,做到預(yù)防性維護、日常維護緊密配合,進行系統(tǒng)的、有計劃的、定期的維護,保證系統(tǒng)在要求的環(huán)境下長期良好地運行,使生產(chǎn)過程控制平穩(wěn)、運行穩(wěn)定,為實 現(xiàn)生產(chǎn)和效益的目標(biāo),提供可靠保證。
