The M.P.E. SC1000 is a Modbus SCADA-ready pump controller designed to perform level control in a wide range of lift station applications. The SC1000 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 10 point conductance probe. The SC1000 alternates the pumps, performs lag pump delays, and provides high and low level alarms. The SC1000 has a variety of control options available in the setup menu that may be used to customize the controller for a specific application.
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 (4-20mA 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 standard alternation, Pump 1 always lead - stays on with other pumps, Pump 1 always lead - turns off with other pumps on, Pumps 1 & 2 alternate, and Pump 3 always last, fixed sequence - Pump 1 always leads, stepped on/off - only one pump runs at a time; 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; Plug-in style connectors
