15. mp that is not operational this pump will conclude that a partner pump is available The information about there being a partner pump will be saved in the memory of both pumps The pump that has just been operational will save level S3 as the on switching level The pump that was not operational and which detected the water level has dropped up to below level S1 will now save level S2 as the on switching level The two pumps will switch on in turns to on switching level S2 when the water level drops to below level S1 of the pump that was currently not operational When the pumps have detected that there is a partner pump they will be switched on in turns when level S2 has been reached When sewage continues to flow into the pump sump the time is saved that is required to reach level S2 and level S1 The pumping time will be corrected based on this The same correction method can be used for volume detection to compensate in changes in the required pumping time when a partner pump is available When one pump cannot supply sufficient pumping capacity to drain away the incoming wastewater the second pump will be switched on when level S3 is reached You can determine when the pumps should be switched off depending on the speed at which the pump sump fills up and the time that is required for it to be pumped and emptied This can be determined by both calculation and detection of the lowest off switching level When one or both p
16. n the previous calculation the time measurements and the detection of the lowest off switching level is repeated and saved and the newly calculated pumping time is assigned to the pump The time will be saved that is required to reach level S3 S2 or S1 when wastewater continues to flow in The period during which the pump is operational will be adjusted to this When the pump has not been operational for a period of 24 hours the pump will start until the lowest off switching level is detected The test run will be automatically activated after every 24 hour period when the water level has not demanded a pump start The pump sends coded impulses to report failures Special modules can decode these impulses and can specify the failures through failure lights or optical contacts 3 5 2 Two pump operation The different operational phases of the pump are combined through an algorithm in two pump operation which enables the pumps to recognise each other The ratio of pumping times between levels S3 S2 S1 and the lowest off switching level are saved individually for each of the two pumps The pumping time that is calculated is assigned to the following 7 pump cycles Volume detection is performed independently after every eighth pump cycle The pumps can be operational simultaneously or in sequence because the choice for starting one of the pumps is random at level S2 or S3 When the water level drops to below level S1 in relation to a pu
