Duplex Microprocessor-Based Controller

The SP6R-LSC is simplicity at its best, incorporating numerous control and monitoring features into one user-friendly unit to monitor levels in wet wells.

 

The easy-to-use microprocessor-based controller monitors the level via a submersible pressure transducer or any other device with a 4-20 mA signal output.  The controller provides pump alternation and has a simulation feature with automatic time out.  The SP6R-LSC displays:

 

  • Level Set Points
  • Pump Run Time
  • Pump Cycle Count
  • Actual Level

 

FEATURES

 

  • 4-20 mA level input with configurable zero and span
  • Bar graph display of wet well level, configurable to feet, inches, percentage or metric
  • Six level set points:Run time meter for each pump
    • High water alarm (with relay output)
    • Start lag pump (with relay output)
    • Start lead pump (with relay output)
    • Stop lag pump
    • Stop lead pump
    • Low level (with relay output)
  • Cycle counter for each pump
  • Automatic alternation
  • Simulation mode with automatic time out
  • Lag pump start delay (1-6000 sec.)
  • Pump run indication
  • Seal fail indication:
    • Indication only
    • Lock out pump with manual reset
    • Run pump as lag only
  • Pump over temperature indication (2 modes):Analog input: 0.1% resolution 4-20 mA signal, built-in noise filtering and averaging
    • Lock out pump with auto rest
    • Lock out pump with manual rest
  • Eight character, alpha-numeric, avionics-grade LED for process value display and program parameters
  • 6 programmable relay outputs
  • On board 24 VDC, 30 mA excitation voltage
  • Easy navigation and set up with keypad
  • Simulation mode to verify proper relay sequence operation
  • Competitively priced
