多负载、SOSO或FOFO输出逻辑
QPC Quadraplex泵控制器用于要求四个泵交替提供相等运行时间的每个泵。交变载荷允许所有泵的磨损相等,从而延长泵的使用寿命。QPC系列有五个输入,即使其中一个输入不能打开或关闭,四个输出也能正常工作。四个LED指示灯显示SPST输出触点通电的负载。QPC有两种顺序配置:顺序开启同步关闭(SOSO)和先开先出(FOFO)。在SOSO序列中,每次激活高电平开关时,都会有一个附加负载通电,而当电平开关失活时,所有负载同时断电。在fofofo序列中,负载以与SOSO序列相同的方式通电,但是当每个电平开关失活时,负载单独断电。在任一顺序中,超前负载位置提前,以均衡每个泵的运行时间。两个模型上的涌流延迟通过防止多个负载同时通电来减少线路下垂。有关SOSO和fofofo排序的更多详细信息,请参阅在线服务手册。
