The single-phase 111-Insider-P monitor fits inside ⅓ and ½ hp, 115 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.
- 基于微控制器的专有电路
- Onboard sensitivity adjustment
- Adjustable restart delay
- Built-in IR communications link
- LED指示
- Constant monitoring of voltage and current protects pumps from fault conditions
- Allows user to adjust the current sensitivity for the dry-well/dead-head trip point from 70 % - 90 % of the full load
- Allows user to select well recovery time delay after a dry-well condition occurs, or to select manual reset
- Used with the Informer, allows user to see stored faults, run time, and also troubleshoot the pump while it’s running
- Provides status and diagnostics for troubleshooting
