当就地设备发生故障，例如变频器发“重故障报警”或者凝结水泵突然跳闸等故障发生时，当前凝结水泵的高压合闸开关断开，并闭合另外一台工频备用凝结水泵高压合闸开关，备用泵工频启动。变频器自动切换到“手动”方式，两个调节门自动切换到“自动”方式，当工频泵启动的瞬间，除氧器上水调整门开度仍然在较大开度，凝结水上水量会因此猛增，为防止除氧器水位过规定值，两个调节门必须在短的时间内关到合适的位置，所以逻辑设计了一旦变频器由于故障原因由自动切手动，调门在10秒钟时间内强制关到当前负荷要求的开度且投入到“自动”方式运行。这个开度也是工频正常运行时调整门的理想开度值。当调整门关到负荷计算值位置并且稳定后，从而完成整个凝结水变频故障的无扰切换。
