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:順序開啟同步關閉(SOSO)和先開先出(FOFO)。在SOSO序列中,每次激活高電平開關時,都會有一個附加負載通電,而當電平開關失活時,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SOSO和fofofo排序的更多詳細信息,請參閱在線服務手冊。
