二、費(fèi)希爾(FISHER)DVC6000閥門定位器調(diào)試步驟 打開375/475手操器,從主菜單(Main Menu) 選擇Hart應(yīng)用(HART Application)從On line找到該定位器。依次進(jìn)入Setup&Diag ——Detailed Setup——Mode——Instument Mode(或者按手操器上快捷鍵直接進(jìn)入)——警告!in service模式被送到儀表當(dāng)中時閥門也許會動(WARNING!Valve may move when in Service mode is sent to the instrument),按OK后進(jìn)入儀表模式(Instrument Mode),選擇Out of service后按ENTER——提示“Instrument mode is already out of service!”,后回到主界面依次進(jìn)入Setup&Diag——Basic Setup——Auto setup——Setup Wizard: 1、選擇你所使用的壓力單位(Pressure units(psi))后ENTER; 2、輸入最大供氣壓力(Max Supply Press(psi))后ENTER; 3、選擇執(zhí)行機(jī)構(gòu)的生產(chǎn)廠家(Actuator Manufcture)后ENTER。以上品牌沒的話選OTHER; 4、如果執(zhí)行機(jī)構(gòu)單作用帶彈簧選3、雙作用帶彈簧選4、雙作用不帶彈簧選2; 5、選ROTARY,下一步根據(jù)閥門零信號時是開選2、關(guān)的話選1,下一步再選1,下一步選YES自動選擇閥門轉(zhuǎn)向及其增益大??; 6、選擇是否有加速器或者快速釋放閥(Is a Volume Booster or Quick Release Present?); 7、提示 執(zhí)行機(jī)構(gòu)的信息正被發(fā)送到儀表當(dāng)中,請稍等“Actuator information is being sent to the instrument. Please wait…”; 8、選擇使用出廠默認(rèn)設(shè)置Use Factory defaults for setup?(Yes is recommended for Initial Setup),Yes后ENTER; 9、提示出廠默認(rèn)設(shè)置正被發(fā)送到儀表當(dāng)中,請稍等“Factory default are being sent to the instrument. Please wait…”; 10、繼續(xù)自動設(shè)置:選擇放大器調(diào)整“To continue Auto Setup.select Relay Adjust”; 11、你是否希望現(xiàn)在進(jìn)行放大器調(diào)整?(Do you wish to run Relay Adjustment Calibration now?)假如是雙作用選擇Yes、單作用選擇No后ENTER; 12、選擇行程標(biāo)定(To continue.select Auto Calib Travel)按OK; 13、你希望現(xiàn)在進(jìn)行自動行程標(biāo)定嗎?(Do you wish to run Auto Travel Calib now ?Select YES if initial setup)選擇Yes后按ENTER; 14、警告!標(biāo)定將導(dǎo)致儀表的輸出突然變化按OK; 15、選擇交點(diǎn)的調(diào)整(Select Crossover Adjust)Manual/Last Value/Default,正常情況下選擇default后ENTER。假如默認(rèn)的調(diào)整后精度比較差 才會選擇Manual手動; 16、下面進(jìn)入自動行程標(biāo)定的過程,完成后儀表模式恢復(fù)到In service!
