Quadraplex Pump Controller by DwyerOmega

The Series-QPC Quadraplex Pump Controller is designed for scenarios requiring four pumps to alternate, ensuring equal runtime and reducing wear. It features five inputs, allowing four outputs to function even if one input fails. Four LED indicators display the active load. The QPC offers two sequence configurations: sequence-on-simultaneous-off (SOSO) and first-on-first-off (FOFO). In SOSO, loads are energized sequentially and de-energized simultaneously, while FOFO de-energizes loads individually. Both sequences advance the lead load position to equalize pump runtime. An inrush delay prevents simultaneous load energization, reducing line sags. For detailed SOSO and FOFO sequencing information, consult the online service manual.
