Littelfuse SymCom 233P PumpSaver 230VAC (1/3-3HP)

Littelfuse SymCom 233P PumpSaver is a pump monitor designed to protect single-phase pumps from dry-well, dead-head, jammed impeller, rapid cycle, overvoltage and undervoltage conditions. The PumpSaver®Plus Model 233P protects 230V, 2 or 3 wire, 1/3 to 3HP pumps. Typical applications include submersible pumps, centrifugal pumps, circulating pumps, cooling pumps, environmental pumps, residential water wells, commercial water wells, irrigation wells, and golf course systems.

Protects Single-Phase Motors From:
• Dry well
• Flow restrictions (dead head)
• Overcurrent (jammed impeller)
• Overvoltage
• Undervoltage
• Rapid cycling

A calibration adjustment allows the Model 233P to be calibrated to your specific pumping applications, thereby reducing the possibility of false or nuisance tripping. A proprietary microcontroller based voltage, power factor and current-sensing circuit constantly monitors for power fluctuations, overcurrent and underload conditions. When an abnormality, such as loss of suction, is detected, the PumpSaver®Plus deactivates its output relay and directly disconnects the pump motor. The PumpSaver®Plus then begins its user-selectable “Restart Delay” (dry-well recovery) timer. When the timer expires or power is removed and reapplied, the PumpSaver®Plus reactivates its output relay and allows the pump to turn back on. An infrared LED communicates directly with a hand-held diagnostic tool called the Informer (sold separately).

NOTE: The PumpSaver®Plus models have a sensitivity adjustment for the dry-well trip point. After calibration is done, you can adjust the sensitivity for the dry-well/dead-head trip point from 70-90% of the full load. This makes the unit even more adaptable to varying pumping applications. If you have a very low producing well, you increase the sensitivity closer to the 90% mark, or if you have a very heavy producing well, you would decrease the sensitivity around the 70% mark.
