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