info

Littelfuse型号111P(115V,⅓至1hp);233P-1.5(230V,⅓至1.5hp);233P(230V,⅓至3hp)是单相泵监控器,用于各种应用,以防止干井、空转、叶轮卡塞、快速循环、过压和欠压情况。

工作原理
校准调整允许根据您的特定泵送应用对装置进行校准,从而减少误跳闸的可能性。独特的基于微控制器的电压和电流感应电路持续监控输入电源的波动、过流和欠流情况。当检测到异常情况(例如吸力损失)时,产品会停用其输出继电器并直接断开泵电机。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。红外LED与名为Informer*(单独出售)的手持式诊断工具进行通信。Informer显示的参数包括校准点、跳闸点、运行时间和上次故障。

There are special considerations for pump cables larger than #10 AWG: In some cases where larger motors are installed with deep-set pumps, pump cables are used that exceed the relay's terminal size.在这些条件下,#10 AWG或#12 AWG的短接头可能是控制箱的解决方案。 Note: All local, state, and national electric codes should be followed when applying this solution.

Note: The description and operations apply to Littelfuse models 111P (115 V, ⅓ to 1 hp); 233P-1.5 (230 V, ⅓ to 1.5 hp); and 233P (230 V, ⅓ to 3 hp).这些型号可针对干井跳闸点进行灵敏度调整。校准完成后,您可以将干井/空转跳闸点的灵敏度调整为满载的70-90%。这使得该装置更能适应不同的泵送应用。如果您的井产量非常低,您把灵敏度提高到接近90%的标记,或者如果您的井产量非常重,您应该把灵敏度降低到70%左右。
