The Model 235P PumpSaverŪPlus is designed to protect single-phase pumps from dry-well, dead-head, jammed impeller and overvoltage and undervoltage conditions. The PumpSaverŪPlus Model 235P protects 5-15 hp, 230V pumps.
A calibration adjustment allows the Model 235P to be calibrated to your specific pumping applications, there, by reducing the possibility of false or nuisance tripping. A unique microcontroller based voltage and current sensing circuit constantly monitors the incoming power for fluctuations causing overcurrent and undercurrent. When an abnormality, such as loss of suction is detected, the PumpSaverŪPlus deactivates its output relay and directly disconnects the pump motor. The PumpSaverŪPlus then begins its user-selectable "Restart Delay" (dry-well recovery) timer. When the timer expires or power is re- moved and reapplied, the PumpSaverŪPlus reactivates its output relay and allows the pump to turn back on. The Model 235P communicates with a hand-held diagnostics tool called the Informer (sold separately). The Informer displays 15 parameters including calibration points, trip points, running points, and last faults.
