Motor and Pump Protection Relays

232-INSIDER

Single-Phase Pump Monitor

Description

The single-phase 232-Insider PumpSaver^®fits inside ¹⁄

, 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*.

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.

*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).
