系列: 231-Insider-P

The 231-Insider-P monitor fits inside ⅓, ½, ¾, and 1 hp, 230 V control boxes. It is designed to protect single-phase, submersible pumps from dry-well, dead-head, jammed impellers, rapid-cycle, overvoltage, and undervoltage conditions. A calibration adjustment allows the Insider to be calibrated to your specific pumping applications, 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. 然后继电器启动其用户可选的重启延迟（干井恢复）计时器。当计时器计数到零或断开电源并重新通电时，继电器将重新激活其输出继电器并重新打开泵。 By leaving the restart delay knob in the reset position, the relay will operate in manual reset mode.

The Insider communicates with a hand-held diagnostics tool called the Informer (sold separately).Informer显示的参数包括校准点、跳闸点、运行时间和上次故障。 An IR Kit-12 (12" fiber optic kit) is included with each Insider, allowing the Informer to access these parameters even when the Insider is enclosed in a control box. This is valuable for troubleshooting the pump while it is running.

NOTE: The 231-Insider-P model has 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. 这使得该装置更能适应不同的泵送应用。 If you have a very low producing well, increase the sensitivity closer to the 90 % mark, or if you have a very heavy producing well, decrease the sensitivity around the 70 % mark.
