電梯開(kāi)門控制分手動(dòng)和自動(dòng):
手動(dòng)開(kāi)門時(shí),當(dāng)電梯運(yùn)行到位后,按下X000后,Y000得電,電動(dòng)機(jī)正轉(zhuǎn),轎廂門打開(kāi),開(kāi)門到位,開(kāi)門行程開(kāi)關(guān)X002常閉觸點(diǎn)斷開(kāi),Y000失電,開(kāi)門結(jié)束
自動(dòng)開(kāi)門時(shí),當(dāng)電梯運(yùn)行到位后,相應(yīng)的樓層接近開(kāi)關(guān)X011或X012或X013閉合,Y000輸出有效,轎廂門打開(kāi)
電梯關(guān)門控制分手動(dòng)和自動(dòng):
手動(dòng)關(guān)門時(shí),當(dāng)按下X001時(shí),Y001得電并自鎖,驅(qū)動(dòng)關(guān)門繼電器使電機(jī)反轉(zhuǎn)關(guān)門,關(guān)門到位X003斷開(kāi),Y001失電,關(guān)門結(jié)束
我就是不是明白自動(dòng)關(guān)門:
這樣說(shuō)的:自動(dòng)關(guān)門時(shí),由定時(shí)器T1來(lái)控制,當(dāng)電梯開(kāi)門到位后,Y000常開(kāi)觸點(diǎn)閉合,T1開(kāi)始計(jì)時(shí),延時(shí)5S后,T1觸點(diǎn)閉合,Y001輸出有效,轎廂門關(guān)閉
不明白開(kāi)門到位后,Y000沒(méi)電了,常開(kāi)觸點(diǎn)怎么閉合呢?
