多負(fù)載、SOSO或FOFO輸出邏輯
QPC Quadraplex泵控制器用于要求四個(gè)泵交替提供相等運(yùn)行時(shí)間的每個(gè)泵。交變載荷允許所有泵的磨損相等，從而延長(zhǎng)泵的使用壽命。QPC系列有五個(gè)輸入，即使其中一個(gè)輸入不能打開(kāi)或關(guān)閉，四個(gè)輸出也能正常工作。四個(gè)LED指示燈顯示SPST輸出觸點(diǎn)通電的負(fù)載。QPC有兩種順序配置：順序開(kāi)啟同步關(guān)閉（SOSO）和先開(kāi)先出（FOFO）。在SOSO序列中，每次激活高電平開(kāi)關(guān)時(shí)，都會(huì)有一個(gè)附加負(fù)載通電，而當(dāng)電平開(kāi)關(guān)失活時(shí)，所有負(fù)載同時(shí)斷電。在fofofo序列中，負(fù)載以與SOSO序列相同的方式通電，但是當(dāng)每個(gè)電平開(kāi)關(guān)失活時(shí)，負(fù)載單獨(dú)斷電。在任一順序中，超前負(fù)載位置提前，以均衡每個(gè)泵的運(yùn)行時(shí)間。兩個(gè)模型上的涌流延遲通過(guò)防止多個(gè)負(fù)載同時(shí)通電來(lái)減少線路下垂。有關(guān)SOSO和fofofo排序的更多詳細(xì)信息，請(qǐng)參閱在線服務(wù)手冊(cè)。
