The M.P.E. SC2000 is a Modbus SCADA-ready pump controller designed to perform level control in a wide range of lift station applications. The SC2000 operates the pumps based on the selected setup values and the wet well level signal. The level input source is menu selectable for either a 4-20 mA pressure transducer or a conductance probe. The SC2000 alternates the pumps, performs lag pump delays, and provides high and low level alarms. The SC2000 has a variety of control options available in the setup menu for customizing the controller for a specific application. Optional I/O is available for VFD speed control and for additional telemetry inputs. The controller can be ordered with up to four additional analog inputs and up to four additional analog outputs.
All setup parameter values may be viewed or changed from the front of unit; 120 VAC input power; Level input source - menu selectable; analog level input (4-20 mA from pressure transducer), level probe (conductance probe with 10 electrodes); 20 VDC power for analog level input loop; 6 amp relay outputs for: pump call, high level, and low level alarms; RS-232 serial port, Modbus RTU Protocol; Alternation modes - menu selectable; Alternation - first on - last off or first on - first off; Alternator logic skips disabled pumps; Remembers lead pump position during power outage; Timed [1 minute] level simulation;
