It is intended for controlling and monitoring SQE pumps using power line communication, so the control unit communicates with the pump via the power cable and nothing additional is run down the borehole.\u003c\/p\u003e\n\u003cp\u003eThe controller operates according to the water pressure measured by a pressure sensor in the installation. When water is consumed, the system detects flow together with pressure change; the controller starts the pump, and pump performance and water flow are controlled by changing the pump speed. The system maintains a constant pressure within the maximum pump performance in spite of varying water consumption.\u003c\/p\u003e\n\u003cp\u003eThe factory setup is constant pressure over 2 to 5 bar (20 to 100 PSI) with a setpoint of 3 bar (50 PSI), CIO 1 configured for an analog sensor and CIO 2 for digital outputs; when the pump is running the output changes contact position. Input signals can be analog sensors or digital switches, and the controller can be used in a range of other applications by changing its configuration: level control filling, level control emptying, pressure control on a digital or an analog input, pump out, and pump monitoring.\u003c\/p\u003e\n\u003cp\u003eOperating indication sits on the front of the controller — power on, pump running, and the Grundfos Eye showing pump status — alongside alarm and warning indication. CU 302 reports dry running and service-needed conditions including no contact to the pump, overvoltage, overtemperature and overload. In a constant-pressure installation it works with a 2 gal (8 litre) diaphragm tank rather than a conventional pressure tank, because the pump follows demand instead of cycling between two switch settings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background:#E1E3E6;border-left:3px solid #B8BDC4;padding:8px 14px;font-size:11.5px;color:#4A4A4F;margin-top:14px;line-height:1.5\"\u003eGenuine Grundfos equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial distributor.\u003c\/div\u003e\n\u003cdiv class=\"gs-sec\"\u003e\n\u003cdiv class=\"gs-h\"\u003eModels \u0026amp; Configurations\u003c\/div\u003e\n\u003cdiv class=\"table-wrapper\"\u003e\u003ctable class=\"gs-tbl\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eConfiguration\u003c\/th\u003e\n\u003cth\u003ePressure sensor\u003c\/th\u003e\n\u003cth\u003eUnits\u003c\/th\u003e\n\u003cth\u003eApproval\u003c\/th\u003e\n\u003cth\u003ePart No.\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCU 302 UL, complete\u003c\/td\u003e\n\u003ctd\u003eNot included\u003c\/td\u003e\n\u003ctd\u003ePSI\u003c\/td\u003e\n\u003ctd\u003eUL\u003c\/td\u003e\n\u003ctd\u003e92799799\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCU 302 UL with PSI sensor\u003c\/td\u003e\n\u003ctd\u003eIncluded\u003c\/td\u003e\n\u003ctd\u003ePSI\u003c\/td\u003e\n\u003ctd\u003eUL\u003c\/td\u003e\n\u003ctd\u003e92817764\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003cp style=\"font-size:12.5px;color:#9B9EA3;margin-top:8px;line-height:1.55\"\u003eBoth variants are the North American UL build reading in PSI.
