The single-phase 232-Insider PumpSaver® fits inside 1⁄3, ½, ¾, and 1 hp, 230 V Grundfos control boxes. The PumpSaver 232-Insider is designed to protect single-phase pumps from dry-well, dead-head, jammed impellers, overvoltage, and undervoltage conditions. Typical applications include residential water wells, commercial water wells, irrigation wells, and golf course systems.
A calibration adjustment allows the 232-Insider to be calibrated to your specific pumping application, reducing the possibility of false or nuisance tripping. A unique microcontroller-based voltage and current-sensing circuit constantly monitors the incoming power for fluctuations, overcurrent, and undercurrent. When an abnormality, such as loss of suction is detected, the 232-Insider deactivates its output relay and directly disconnects the pump motor. The 232-Insider then begins its user-selectable restart delay (dry-well recovery) timer. When the timer counts to zero or power is removed and reapplied, the 232-Insider reactivates its output relay and turns the pump 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
Features & Benefits:
- Proprietary microcontroller-based circuitry: Constant monitoring of voltage and current status for maximum protection
- Adjustable restart delay: Allows user to select well recovery time delay after a dry-well condition n occurs, or to select manual reset
- Built-in IR communications link: Used with the Informer, allows user to see stored faults, run time, and troubleshoot while the pump is running
- LED indication: Provides status and diagnostics for troubleshooting
