Protection Relays Motor and Pump Protection 111-INSIDER-P / 231-INSIDER-P Single-Phase Pump Monitor Description The Littelfuse 111-Insider-P single-phase products fit inside and hp, 115 V control boxes and the 231-Insider-P fits inside , , , and 1 hp, 230 V control boxes. Both models are designed to protect single-phase pumps from dry-well, dead-head, jammed impeller, rapid-cycle, overvoltage, and undervoltage conditions. A calibration adjustment allows the Insider 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 constantly monitors the incoming power for fluctuations, overcurrent, and undercurrent. When an abnormality, such as loss of suction is detected, the product deactivates its output relay and directly disconnects the pump motor. The unit then begins its user-selectable restart delay (dry-well recovery) timer. When the timer counts to zero or power is removed and reapplied, the unit reactivates its output relay and turns the pump back on. By leaving the restart delay knob in the reset position, the unit will operate in manual reset mode. The Insider communicates with a hand-held diagnostics tool called the Informer (sold separately). The Informer displays parameters including calibration points, trip points, run time and last faults. An IR Kit-12 (12 fiber optic kit) is included with each Wiring Diagrams Insider, allowing the Informer to access these parameters even when the Insider is enclosed in a control box. This is valuable for See next page. troubleshooting the pump while it is running. NOTE: The 111/231-Insider-P 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 Accessories the 70 % mark. Informer A hand-held diagnostic tool that uses an infrared receiver to access information which can be Features & Benefits helpful for troubleshooting the system.
