5.3.6. Control panelThe modern control panels are equipped with a device for measuring the energy consumption, the number of working hours, as wellas with a counter of the pumps start ups and thus their work is in sequence and blocking is avoided during the compulsory idle time.According to the number of pumps the controllers used in PROFOS are the following:● LC 108 is a controller for one pump.● LCD 108 is a controller for two pumps.Depending on the pump’s nominal current, the start up and the selection of a panel is the following:● Up to 23А/11 kW (P1) - direct on line (DOL).● Up to 72А/30 kW (P1) - on line.„star-delta“.(Y/D).5.3.7. Level switchesIn the PROFOS pump stations are mounted level switches. They are used to control the levels in the draw tank and transmit the datato the corresponding control panels. This type of level switches is compatible with the control panels LC 108 and LCD 108.● In case of one pump the number of level switches is three - „stop“ level, „start“ level and „alarm“ level.● In case of two pumps the number of level switches is four - „Stop“ level one piece, „start“ level two pieces for every pump and. . alarm“ level one piece.5.3.8. Additional equipment compatible with PROFOS● Rain holder tanks in gravity sewerageIn the mixed sewerages in front of the pump station is planned to be mounted rain holder tanks. These are polyethylene ribbed tanksof Pipelife with a capacity of 3000 l, 5000 l ECO-T type and tanks with a capacity of 8000 l, 12000 l, 20000 l, 30000 l, 40000 l or 50000l ECO TR type with a wall thickness of 12 mm (see Table 6 with the offered tanks by Pipelife). They are with a guaranteed water tightness,easy transport and assembly, and with good exploitation qualities.Their location is close to the pump station, before it and their laying is not different from the tanks used in ECO systems (see CatalogueECO Integrated waste water treatment systems). With them it is aimed to be reduced the hydraulic pressure in the pump stationby retaining part of the water quantity in the tank during rain.The tank serves for retaining part of the suspended substances in the waste atmospheric waters and reduces their contents in thesewerage after the pump station.The tank is equipped with a ventilation and easy for revision, and for taking out the deposited sediments. Its expedience depends onits design and is proven for every case with a technical economic analysis.ECO - T800 800600ECO - TRHh11h2D2Hh1h2DLLPipelifewww.pipelife.com18
