    DFL3000M恒压供水变频器的接线和参数设置操作

    DFL3000M系列是一款可以安装在电机接线盒上的背负式恒压供水变频器,它可分为单相输入单相输出恒压供水变频器,型号为DFL3000M-HYGS1,专用于单相220v的水泵;单相输入三相输出的,型号为DFL3000M-HYGS3,用于三相220v的水泵。其外形如下:

    恒压供水变频器

    3000M系列于电机和压力传感器的接线图如下所示,220v的电源连接AC,AC两个端子,单相的水泵连接U,V两个端子:


    压力变送器于变频器的连接如下图,压力变送器的1,2两个点分别连接V/I,12V.

    接好线之后,通上电源,一般变频器上会显示两个压力,左边为设置压力,右边为管道的压力。在一拿到变频器,如果没有跟销售人员说明所用是何种压力传感器,有可能还需要设置你相对应的压力传感器,如视频所示

    首先,先进入系统,每一台变频器为了不误操作都有一个密码,为0168。先按左上角的编程键两次,当显示.0000时,按上下的方向,输入0168,然后按左下方的保存确认键,这样就成功进入系统。

    进入系统后显示参数pr130,转是设置压力传感器量程的参数号,比如我们用的压力传感器的最大值为1.0mpa,可以按以下视频操作。在显示pr130时,按左下角的功能保存确认键,进入该参数设置,设置为d01.00.此处数值单位为mpa。


    一般只是需要设置量程就可以,为了用户能够更简单的使用3000M变频器,变频器出厂时设置了一次恢复模式,比如你根据使用压力传感器的输出信号,比如0-5vdc,0.5-4.5vdc,4-20ma,三个选择。与下表pr068 中的d0010,d0017,d0018相对应
