Littelfuse SymCom 232-Insider PumpSaver 230V (1/3-1HP)

Littelfuse SymCom 231-Insider-P 1-Phase PumpSaver®Plus is a current monitor designed to protect single-phase pumps from dry-well, dead-head, jammed impeller, overvoltage and undervoltage conditions. The 232-Insider fits inside 1/3, 1/2, 3/4, and 1HP, 230V Grundfos control boxes and has an input voltage of 230VAC with an input load range of 1/3–1 HP. Typical applications include residential water wells, commercial water wells, irrigation wells, and golf course systems.

A calibration adjustment allows the Insider-P to be calibrated to your specific pumping applications, thereby reducing the possibility of false or nuisance tripping. A unique microcontroller-based voltage and current sensing circuit constatly monitors the incoming power for fluctuations, overcurrent and undercurrent. When an abnormality, such as loss of suction is detected, the PumpSaver deactivated 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 counts down to zero or power is removed and reapplied, the PumpSaver reactivated its output relay, allowing the pump to turn back on. By leaving the restart delay knob in the reset position, the 232-Insider will operate in manual reset mode. An infrared LED communicates directly with a hand-held diagnostic tool called the Informer*. 

*The Informer: a hand-held diagnostic tool that uses an infrared receiver to access information that can be helpful for troubleshooting the system (sold separately)

The 232-Insider communicates with a easy to use hand held diagnostics tool (sold separately). The Informer displays 15 parameter including calibration points, trip points, running points, and last faults. Infrared LED communicates directly with the PumpSaver Plus making it easy to diagnos those hassling pump issues even when the 232-Insider is enclosed in a control box. This is a valuable for troubleshooting the pump while it is running.

Note: The use of flow restrictors or unusually high head pressures at the time of calibration may interfere with the detection of dead-head conditions.
