Ormec ORN-50/AFEHS

Ormec ORN-50/AFEHS當(dāng)電梯定向上行時(shí)，上行方向繼電器SFJ0015、快車輔助接觸器KF、快車運(yùn)行接觸器KY0501、門鎖繼電器MSJ、上行接觸器SX0502均得電吸合，抱閘打開，電梯上行。當(dāng)轎廂碰到上強(qiáng)迫換速開關(guān)SQH0016時(shí)，PLC內(nèi)部鎖存繼電器KRRP1001得電吸合，定時(shí)器Tim10、Tim11開始定時(shí)，其定時(shí)的時(shí)間長短可視端站層距和梯速設(shè)定。上強(qiáng)迫換速開關(guān)動作后，電梯由快車運(yùn)行轉(zhuǎn)為慢車運(yùn)行，正常情況下，上行平層時(shí)電梯應(yīng)停車。如果轎廂未停而繼續(xù)上行，當(dāng)Tim10設(shè)定值減到零時(shí)，其常閉點(diǎn)斷開，慢車接觸器MY0503和上行接觸器SX0502失電，電梯停止運(yùn)行。在驕廂碰到上強(qiáng)迫換速開關(guān)SQH0016后，由于某些原因電梯未能轉(zhuǎn)為慢車運(yùn)行，及快車運(yùn)行接觸器KY0501未能釋放，當(dāng)Tim11設(shè)定值減到零時(shí)，其常閉點(diǎn)斷開，快車運(yùn)行接觸器KY0501和上行接觸器SX0502J均失電，電梯停止運(yùn)行。因此，不管是慢車運(yùn)行還是快車運(yùn)行，只要上強(qiáng)迫換速開關(guān)SQH發(fā)出信號，不論端站其他保護(hù)開關(guān)是否動作，借助Tim10和Tim11均能使電梯停止運(yùn)行，從而使電梯端站保護(hù)更加可靠。~~~~~~~~~~~~~~~~~~~~~~~~~~~~
