PMU 3將(jiang)0...10 Vdc信(xin)(xin)號(hao)轉(zhuan)換為24 Vac三點控(kong)制(zhi)信(xin)(xin)號(hao)。執(zhi)(zhi)行(xing)(xing)(xing)器(qi)的(de)容量不得超(chao)過 36 VA。當輸(shu)入(ru)信(xin)(xin)號(hao)發生變化(hua)時(shi)，只要(yao)變化(hua)需(xu)要(yao)，PMU 3就會移動(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)(xing)器(qi)的(de)位置(zhi)。接(jie)通(tong)電源后，PMU3在選定的(de)驅(qu)(qu)動(dong)(dong)(dong)時(shi)間內將(jiang)執(zhi)(zhi)行(xing)(xing)(xing)器(qi)驅(qu)(qu)動(dong)(dong)(dong)到(dao)(dao)負位置(zhi)。當輸(shu)入(ru)低(di)于 0.5 V 時(shi)，執(zhi)(zhi)行(xing)(xing)(xing)器(qi)每 5 分鐘被驅(qu)(qu)動(dong)(dong)(dong)到(dao)(dao)負位置(zhi)，持續樹(shu)秒。當輸(shu)入(ru)超(chao)過 9.5V 時(shi)，執(zhi)(zhi)行(xing)(xing)(xing)器(qi)將(jiang)每 5 分鐘被驅(qu)(qu)動(dong)(dong)(dong)到(dao)(dao)正(zheng)位置(zhi)持續樹(shu)秒。24 Vac 電壓連接(jie)到(dao)(dao)執(zhi)(zhi)行(xing)(xing)(xing)器(qi)電機(ji)(ji)的(de)公共(gong)端(duan)子，PMU 3通(tong)過將(jiang) G0 連接(jie)到(dao)(dao)電機(ji)(ji)的(de)控(kong)制(zhi)端(duan)子來(lai)驅(qu)(qu)動(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)(xing)器(qi)。LED指示執(zhi)(zhi)行(xing)(xing)(xing)器(qi)的(de)驅(qu)(qu)動(dong)(dong)(dong)方向。電機(ji)(ji)運行(xing)(xing)(xing)時(shi)間的(de)范圍(wei)在外殼內選擇(ze)，可(ke)以通(tong)過微調(diao)器(qi)K（運行(xing)(xing)(xing)時(shi)間系(xi)數(shu)）進行(xing)(xing)(xing)調(diao)整。
