BR-10A型精小(xiao)型耐(nai)腐(fu)蝕電動執行(xing)器調節(jie)模塊調試方法：

1、手動將電動裝置(zhi)置(zhi)于中間(jian)位(wei)置(zhi)

2、接通AC380電(dian)(dian)源，電(dian)(dian)源指(zhi)示燈(deng)亮(liang)；若電(dian)(dian)源缺相，則缺相指(zhi)示燈(deng)亮(liang)

3、拔碼開關的正作(zuo)用(yong)和反作(zuo)用(yong)不能同時(shi)拔為有(you)效

4、正作用時位(wei)置反饋信(xin)號(hao)(hao)調(diao)節(jie)(jie)。將電動裝置打(da)到(dao)全關位(wei)置，調(diao)節(jie)(jie)整體模(mo)塊上的“調(diao)零”電位(wei)器(qi)，使(shi)兩(liang)測試點的電壓接近零（≤2mV），然后調(diao)節(jie)(jie)“4mA”電位(wei)器(qi)使(shi)輸出信(xin)號(hao)(hao)為4mA；將電動裝置打(da)到(dao)全開位(wei)置，調(diao)節(jie)(jie)“20mA”電位(wei)器(qi)使(shi)輸出信(xin)號(hao)(hao)為20mA。上述調(diao)節(jie)(jie)只須一次即可完成。

注：“調零”、“4mA”、“20mA”電位器均為順時針方向旋轉輸出信號增大，反之減小，如發現順時針旋轉上述電位器時，輸出信號減小，請將電位器兩邊的線互換。
5、為了保證電動裝置在自動控制中的定位精度，必須調節靈敏度。一體化執行器靈敏度小，定位精度高，但容易產生振蕩；靈敏度大，不容易產生振蕩，但定位精度差。調節“靈敏度”電位器可在二者之間取舍，使其不產生振蕩為*佳調整值

6、輸入控(kong)制信(xin)號丟失后(hou)，丟信(xin)指示燈(deng)亮

7、當出現開(kai)閥(fa)或(huo)關閥(fa)某(mou)一方(fang)向(xiang)(xiang)(xiang)鎖死后，向(xiang)(xiang)(xiang)另一方(fang)向(xiang)(xiang)(xiang)運行3秒即(ji)可解(jie)鎖

BR-10A型精小型耐腐蝕(shi)電動執行器(qi)使用(yong)方法：

1、線與撥碼選擇

ECM-2C型模塊按下圖所示完成(cheng)模塊與執行器接線。位(wei)置電位(wei)器的阻值應為≥1KΩ

用萬用表檢查模塊上的電機(ji)邊線端，確保無短路(lu)現象。

以上連線檢查無誤后(hou)，接入220V電源線。

2、調(diao)試

先通過執行器上的手輪將執行器動到全行程(cheng)的中(zhong)間位(wei)置。

在無控(kong)制(zhi)電流(及丟信)情況下，將丟信動(dong)作(zuo)撥碼(ma)(ma)開(kai)關(guan)撥到“開(kai)”位置(zhi)，接通(tong)AC200V電源，此時(shi)電源批示(shi)燈和丟信指示(shi)燈點(dian)亮，執(zhi)行器應向開(kai)方(fang)向動(dong)作(zuo)：將丟信動(dong)撥碼(ma)(ma)開(kai)頭撥到“關(guan)”位置(zhi)，此時(shi)執(zhi)行器應向關(guan)方(fang)向動(dong)作(zuo)：將丟信動(dong)作(zuo)撥碼(ma)(ma)開(kai)關(guan)撥到“停止”位置(zhi)，此時(shi)執(zhi)行器應停止動(dong)作(zuo)：若執(zhi)行器動(dong)作(zuo)相反，應將“電機開(kai)”和“電機關(guan)”接線交換。

閥(fa)位(wei)反饋(kui)電(dian)(dian)(dian)(dian)流(liu)調試(shi)，將執行(xing)器(qi)(qi)(qi)動(dong)作(zuo)到關位(wei)，調節(jie)“調零(ling)”電(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)，使測試(shi)點兩(liang)端的(de)電(dian)(dian)(dian)(dian)壓(ya)差為零(ling)，然(ran)后調節(jie)“低端”電(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)使輸出信號為4mA;將執行(xing)器(qi)(qi)(qi)動(dong)作(zuo)到開位(wei)，調節(jie)“”電(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)使輸出信號為20mA。上述調節(jie)只(zhi)需一次(ci)即可完成（“調零(ling)”、“低端”和“ ”電(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)均是順時(shi)針(zhen)方(fang)向(xiang)(xiang)增大(da)，逆時(shi)針(zhen)方(fang)向(xiang)(xiang)減小）。注(zhu)意：當(dang)閥(fa)位(wei)由關到開時(shi)，閥(fa)位(wei)電(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)中心軸(zhou)頭對(dui)地GND電(dian)(dian)(dian)(dian)壓(ya)的(de)值應由小到大(da)變化。

為了保證執(zhi)行器在(zai)自(zi)動(dong)控制中的(de)定位(wei)精度，須調(diao)節靈敏(min)(min)范圍。靈敏(min)(min)度范圍小(xiao)，定位(wei)精度高，但(dan)(dan)容(rong)易(yi)產生(sheng)振(zhen)蕩。靈敏(min)(min)度范圍大，不(bu)容(rong)易(yi)產生(sheng)振(zhen)蕩但(dan)(dan)定位(wei)精度差(cha)。調(diao)節“靈敏(min)(min)度”電位(wei)器可以二位(wei)這間(jian)取折(zhe)衷，使其不(bu)產生(sheng)振(zhen)蕩為***佳調(diao)節值 

注意：

1、靈(ling)敏度電位器(qi)，為單圈270°電位器(qi)，到位后不要用力旋(xuan)轉，否則會損壞電位器(qi)。

2、調零、低端(duan) 、電(dian)位器，均勻精密多圈(quan)電(dian)位器（可旋(xuan)轉約25圈(quan)）。
