Symcom PumpSaver® 1 ph Pump Protection Relay, 230 VAC, SPST/NO (1 Form A) Contact

The 233P is a 1-phase pump monitor designed to protect 1-phase pumps from dry well, dead head, jammed impeller, rapid cycle, overvoltage and undervoltage conditions. The 233P protects 230 volt, 2 or 3-wire, 1/3 to 3 hp pumps. A calibration adjustment allows the 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 233P deactivates its output relay and directly disconnects the pump motor. The relay then begins its user selectable "Restart Delay" (dry well recovery) timer. When the timer expires or power is removed and reapplied, the relay 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, the informer displays parameters including calibration points, trip points, run time and last faults.
