檢修工藝及技術(shù)要求
1、測量電壓時,要用數(shù)字電壓表或精度為1%的萬能表測量
2、電源機(jī)架,CPU主板都只能在主電源切斷時取下
3、在RAM模塊從CPU取下或插入CPU之前,要斷開PC的電源,這樣才能保證數(shù)據(jù)不混亂
4、在取下RAM模塊之前,檢查一下模塊電池是否正常工作,如果電池故障燈亮?xí)r取下模塊PAM內(nèi)容將丟失
5、輸入/輸出板取下前也應(yīng)先關(guān)掉總電源,但如果生產(chǎn)需要時I/0板也可在可編程控制器運(yùn)行時取下,但CPU板上的QVZ(超時)燈亮

6、撥插模板時,要格外小心,輕拿輕放,并運(yùn)離產(chǎn)生靜電的物品
7、更換元件不得帶電操作
8、檢修后模板安裝一定要安插到位
通過以上五大點(diǎn)的描述,相信大家對PLC的維修與保養(yǎng)有了一定的認(rèn)識。
