235P - Sym. Com 1-Phase Pumpsaverplus 230V 5-15HP CT Required
The Model 235P Family
The Model 235P Pump. Saver®Plus is designed to protect single-phase pumps from dry-well, dead-head, jammed impeller and overvoltage and undervoltage conditions. The Pump. Saver®Plus 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 Pump. Saver®Plus deactivates its output relay and di-rectly disconnects the pump motor. The Pump. Saver®Plus then begins its user-selectable "Restart Delay" (dry-well recovery) timer. When the timer expires or power is re-moved and reapplied, the Pump. Saver®Plus reactivates its output relay and allows the pump to turn back on.
The Model 235P communicates with a hand-held diag-nostics tool called the Informer (sold separately). The Informer displays 15 parameters including calibration points, trip points, running points, and last faults.
An external current transformer is required for opera-tion.
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.
