关键字：阀门定位器 http://www.samson-china.com/ 阀门定位器在使用的过程中通常会与智能模块搭配使用，这样可以定位器的使用性能，并且为远端控制系统提供精确的阀门开度信号。模块采用新一代全数字技术研发，并采用全进口元件制作，具有精度高、抗干扰能力强、工作稳定等优点。那么阀门定位器如何调试智能信号模块呢？1.电气连接分别在阀门定位器的EP和PTM端连接好4~20MA输入信号和24V直流稳压电源,并且串联好电流表以便观察PTM端反馈信号电流。这里要注意尽量不要直接连接DCS系统调试，除非能确保DCS系统是绝对完好，以便尽快完成智能模块的调试。2.使模块进入调试状态:按住阀门定位器最右边一个按键不放,待模块上的指示灯亮起，然后放开该按键，指示灯闪烁即表示模块进入调试状态。观察电流表读数:此时电流表读数应为4MA,如果偏差，可按"+”或“-”键调整电流使电流值符合要求。上述提到的阀门定位器EP端为定位器指令输入端，于输入4~20MA的指令信号。PTM端接直流24V稳定电源，如串联电流表或电流传感器，可观察电流变化。这里要注意PTM端必需接直流稳定电源。德科蒙过程控制(武汉)有限公司座机:027-88062221传真:027-88068180邮箱: sales@whdkm.com原文出处：http://www.samson-china.com/a/xwzx/276.htmlABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfV0.&dt=1602576869659&bpp=26&bdt=53&idt=205&shv=r20201008&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=2064105385768&frm=23&ife=1&pv=2&ga_vid=1533922632.1602576870&ga_sid=1602576870&ga_hid=179166831&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=8&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530529%2C44726948&oid=3&pvsid=1223368769730867&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.fn38ce12ye3v&fsb=1&dtd=251" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.fn38ce12ye3v" data-load-complete="true"> |
