5-維護及故障的清除2-安裝2-0介紹遠(yuǎn)程位置調(diào)節(jié)器可以用來直接安裝或者準(zhǔn)備直接安裝，在轉(zhuǎn)動裝置上或者單獨在架子上通過一些90度旋轉(zhuǎn)裝置來安裝。如果此遠(yuǎn)程位置調(diào)節(jié)器在執(zhí)行器上準(zhǔn)備安裝，2.1和2.2章可被忽略。2.1在調(diào)節(jié)器直接安裝部分移動執(zhí)行器葉片到中間運行位置使輸出量如圖1所示，這是防止在確定方向上出現(xiàn)并發(fā)問題的根本。移動調(diào)節(jié)器的封蓋，松開五個M4 槽溝頂部的螺絲保持紅色塑膠輸送盤在機體內(nèi)。拆開連到伺服閥上的兩根金屬絲，用軸等抬起整個輸送盤裝配。在如圖1所示的方向上將調(diào)節(jié)器機體閂緊到執(zhí)行器上 ，要注意使O型圈在執(zhí)行器出口密封的位置上。并使執(zhí)行器的軸位于孔的正中心位置。對于07和大的樣式，在執(zhí)行器角落上方按圖2所示逆向反斜線安裝彈簧。觀測可到達(dá)調(diào)節(jié)器軸的范圍，受信號區(qū)輪子分壓計的正確運行方向限制，由不銹鋼帶驅(qū)動（見圖3）.用中間范圍附近的軸將輸送盤/軸裝配回調(diào)節(jié)器盒，在維修它的位置在中間范圍附近時，“感應(yīng)”一下執(zhí)行器上的調(diào)節(jié)器。兩個軸是否彼此恰當(dāng)?shù)卦诤线m的位置這是根本的問題，如果超出了90度角那么信號區(qū)輪子可能被迫離得太遠(yuǎn)并且在后來執(zhí)行器運行的過程中對機械驅(qū)動可能產(chǎn)生損傷。在運行末尾用執(zhí)行器安裝到遠(yuǎn)程位置調(diào)節(jié)器上是可能的，但經(jīng)驗告訴我們這樣的話對于執(zhí)行器的移動方向產(chǎn)生錯誤的概率非常高。2-2離散的遠(yuǎn)程位置調(diào)節(jié)器的安裝設(shè)計與生產(chǎn)安裝調(diào)節(jié)器和執(zhí)行器之間的成套工具已經(jīng)遠(yuǎn)遠(yuǎn)超出了我們這本手冊的范圍。調(diào)節(jié)器與執(zhí)行器的軸良好排列這是很根本的。另一個根本問題是執(zhí)行器運行90度角，調(diào)節(jié)器通過90度角，能保證這樣的最簡單的辦法是用指示器來安裝不連續(xù)的部件。2-3空氣和電力連接2-3-1空氣供給連接空氣供應(yīng)連接到供應(yīng)口處（壓力在3.5到7bar之間,50到100psi）?？諝庖欢ㄒ獫崈?、干燥、無油。質(zhì)量等級3.4.4就滿足(根據(jù)ISO標(biāo)準(zhǔn)8573.1),這就意味著最大粒子尺寸是微米,最大露點 3deg.C，最大含油量每立方米5mg。圖4注：蓋子內(nèi)部標(biāo)簽上的內(nèi)部電氣連接接線端經(jīng)常需要修改。當(dāng)連接或者調(diào)整要移動蓋子時不要擦掉軸封帽上的潤滑油。2-3-2DIN插頭選擇如果沒有可選擇的限位開關(guān)供給那么DIN插頭開關(guān)的模式只能用遠(yuǎn)程位置調(diào)節(jié)器盒上的四向DIN插頭。2-3-3遠(yuǎn)程位置調(diào)節(jié)器信號此調(diào)節(jié)器信號必須為4-20mA。此調(diào)節(jié)器給出0度到90度線性或者非線性信號。這個調(diào)節(jié)器是循環(huán)產(chǎn)生動力的。（此信號本身提供所有的電氣動力，不需要其它分離的動力源）。為提供足夠的動力，需要接近6-8V信號電流來通過它。3-數(shù)字遠(yuǎn)程位置調(diào)節(jié)器示意功能圖表（見原件）4-設(shè)置4-0介紹當(dāng)調(diào)節(jié)器/執(zhí)行器按應(yīng)用程序聯(lián)結(jié)安裝完，如有必要要設(shè)置控制調(diào)整。對大多數(shù)的應(yīng)用程序來說工廠的設(shè)置都是很滿意-信號響應(yīng)為4-20mA時低電流和高電流點被設(shè)置到0-90度，流量調(diào)整器被設(shè)置為最大運行速度，并且對于大多數(shù)應(yīng)用程序來說它的增加和減小比例被調(diào)整到一個很好的值。在低電流和高電流設(shè)置中跳線應(yīng)為“關(guān)閉”位置以給出一個線性的特性。如果要改變設(shè)置，仔細(xì)閱讀下列章節(jié)。4-設(shè)置4-1設(shè)置運行速度使用排氣量調(diào)整螺母來設(shè)置運行速度（見表4）。這只適用于在工廠設(shè)置的最大值基礎(chǔ)上減小速度。4-2設(shè)置可選限位開關(guān)凸輪對于每個開關(guān)來說此開關(guān)可以被設(shè)置在任何位置，通過松開凸輪夾緊螺母和旋轉(zhuǎn)凸輪來定位。首先設(shè)置較低的凸輪。4-3縱覽-電氣設(shè)置EL數(shù)字遠(yuǎn)程位置調(diào)節(jié)器回路的操作可用來使執(zhí)行器精確勻稱地輸入電流，線性或者非線性可以通過操作線的刻度來測量，或者是曲線圖表，在兩個用戶之間它的操作范圍被詳細(xì)說明。遠(yuǎn)程位置調(diào)節(jié)器電路完全是依靠來自于4-20mA的輸入信號來產(chǎn)生動力的。通過三個按鈕及可選參數(shù)的紅色LED指示器，它是可調(diào)與可校準(zhǔn)的。此遠(yuǎn)程位置調(diào)節(jié)器也是可以通過自已自動進(jìn)行校準(zhǔn)的。所有的調(diào)整和校準(zhǔn)數(shù)據(jù)可被自動存儲。遠(yuǎn)程位置調(diào)節(jié)器可以通過線性或者非線性裝置來操作。非線性操作可能過裝配一個跨線聯(lián)結(jié)到遠(yuǎn)程位置調(diào)節(jié)器上來實現(xiàn)。如果調(diào)節(jié)器的動力聯(lián)結(jié)位于“ON”（見圖6所示位置），它就會做為非線性操作直到結(jié)束這一狀態(tài)。相反地，如果調(diào)節(jié)器的動力聯(lián)結(jié)處于“OFF”，它將作為線性裝置進(jìn)行操作直到結(jié)束此狀態(tài)。操作是否近按線性或者非線性進(jìn)行，操作器有兩種清晰的模式，正常模式與調(diào)整模式。4-4默認(rèn)的設(shè)置重設(shè)程序在一些操作模式下產(chǎn)生動力時，此調(diào)節(jié)器可以通過按壓三個按鈕（UP，DOWN，SET）對默認(rèn)值進(jìn)行重新設(shè)置。全部現(xiàn)有的比例增益、衰減、曲線選擇和校準(zhǔn)數(shù)據(jù)等會被記錄下來。這個程序?qū)τ诜乐乖谛?zhǔn)中產(chǎn)生錯誤是很很必要的。程序設(shè)置結(jié)束之后此遠(yuǎn)程位置調(diào)節(jié)器應(yīng)時常進(jìn)行調(diào)整。4-5進(jìn)入與退出安裝模式安裝模式可以從常規(guī)模式中通過同時按壓UP和SET按鈕來進(jìn)行選擇。這會使標(biāo)有PGAIN標(biāo)簽的指示燈連續(xù)亮起。在安裝模式中下列的每項參數(shù)都可以按需要按壓UP或者DOWN按鈕來進(jìn)行選擇。PGAIN比例增益DAMP衰減CURVE非線性曲線選擇LOW低電流點校準(zhǔn)HIGH高電流點校準(zhǔn)POT設(shè)置范圍分壓計底部反饋當(dāng)需要的參數(shù)已經(jīng)選擇好用于調(diào)整，SET按鈕已經(jīng)按下允許調(diào)整進(jìn)行臨近選擇參數(shù)的指示燈開始閃亮，用來指示調(diào)整模式已經(jīng)啟動。 要退出調(diào)整模式，再次按下SET按鈕指示燈連續(xù)閃亮。要退出安裝模式，重新按下DOWN按鈕，這時指示燈不亮，遠(yuǎn)程位置調(diào)節(jié)器返回到常規(guī)模式。4-6自動結(jié)束搜索程序遠(yuǎn)程位置調(diào)節(jié)器在一些機械停止之間會自動進(jìn)行自身的校準(zhǔn)（可以是執(zhí)行器的停止或者是內(nèi)部停止）。4-7比例增益和衰減的設(shè)置選擇安裝模式，并且第一個參數(shù)先擇是自動PGAIN比例增益。按壓SET按鈕，PGAIN指示燈會開始閃亮，這個參數(shù)值現(xiàn)在就可以通過根據(jù)需要按壓UP或者DOWN按鈕來增大或者減小。有29個PGAIN的設(shè)置可被選擇，4 安裝（續(xù)）4-7在調(diào)整DAMP的設(shè)置時，遠(yuǎn)程位置調(diào)節(jié)器是活動的并且隨輸入信號而變化。這樣，就可以找到最優(yōu)化的響應(yīng)信號。試著快速改變信號以讓遠(yuǎn)程位置調(diào)節(jié)器全速前進(jìn)45度或更多后達(dá)到設(shè)置點，同時調(diào)節(jié)DAMP的安裝，避免遠(yuǎn)程位置調(diào)節(jié)器過了設(shè)置點。重復(fù)這一過程，直至完成安裝。安裝完成以后，按SET按鈕終止調(diào)節(jié)模式，此時，DAMP LED（發(fā)光二級管）會持續(xù)發(fā)光。4-8 低電流點（LCP）和高電流點（HCP）的設(shè)置通過設(shè)置低電流點和高電流點，能夠精確校準(zhǔn)遠(yuǎn)程位置調(diào)節(jié)器的特性。每個點可以通過位置和輸入電流確定。這些點可以在遠(yuǎn)程位置調(diào)節(jié)器運動范圍內(nèi)的任何位置，并且輸入信號（電流）的范圍為4-20mA。另外，高電流點的電流至少要比低電流點的電流高5mA。低電流點和高電流點的距離越遠(yuǎn)，對遠(yuǎn)程位置調(diào)節(jié)器的調(diào)節(jié)就越精確。在線性和非線性的操作中都允許前向運動和反向運動，可以通過設(shè)置不同的輸入信號范圍加以區(qū)分（如4-12mA, 12-20mA ）要設(shè)定低電流點,在設(shè)置模式中選擇LOW參數(shù)，方法是按UP（向上）按鈕直到LOW LED（低發(fā)光二級管）持續(xù)發(fā)光。按SET按鈕，選擇Adjust Mode（調(diào)節(jié)模式），此時LOW LED將會閃爍。在4-20mA范圍內(nèi)選定一個電流值作為LCP，但要注意，在4-20mA范圍內(nèi)改變電流并不能使遠(yuǎn)程位置調(diào)節(jié)器在此時運動，在調(diào)節(jié)模式選定之前遠(yuǎn)程位置調(diào)節(jié)器的角度就已經(jīng)選定，與輸入電流無關(guān)。按向上或者向下按鈕使遠(yuǎn)程位置調(diào)節(jié)器移動到你想設(shè)置為HCP的角度上，如果持續(xù)按向下按鈕，遠(yuǎn)程位置調(diào)節(jié)器將會穩(wěn)定的來回運動。如果輕按按鈕，遠(yuǎn)程位置調(diào)節(jié)器將會移動大約1/40度。輕按按鈕可以使遠(yuǎn)程位置調(diào)節(jié)器比較精確的達(dá)到預(yù)期位置。當(dāng)遠(yuǎn)程位置調(diào)節(jié)器達(dá)到預(yù)期位置并且輸入電流達(dá)到設(shè)定值后，再按SET按鈕記錄下作為HCP的位置和電流。此時，遠(yuǎn)程位置調(diào)節(jié)器會有小的跳動，然后回到原來位置，遠(yuǎn)程位置調(diào)節(jié)器將會回到設(shè)置模式，此時HIGH LED 將會持續(xù)發(fā)光。輸入電流的變化將會在遠(yuǎn)程位置調(diào)節(jié)器上有反應(yīng)。注意：一旦按了SET按鈕，HCP的位置和信號將會存儲為非易失性記憶的狀態(tài)，在遠(yuǎn)程位置調(diào)節(jié)器離開設(shè)置模式之前將會一直保留。4-9 遠(yuǎn)程位置調(diào)節(jié)器的順時針和逆時針回動前一部分介紹的LCP 和HCP設(shè)置同樣適用于遠(yuǎn)程位置調(diào)節(jié)器的回動，表一列出了回動的設(shè)定。然而，在失去信號時運動方向?qū)⒉粫淖?。如何改變方向，見下一部分?-10 失去信號時如何改變方向在氣壓足夠，信號不連續(xù)或電流低于3.5mA時，遠(yuǎn)程位置調(diào)節(jié)器使運動方向由伺服真空管的位置設(shè)定。這個運動的方向與前面描述的LCP和HCP的設(shè)置無關(guān)。對于兩個同時起作用的遠(yuǎn)程位置調(diào)節(jié)器，在失去氣壓時的運動是無法預(yù)測的。如果要固定失去氣壓時的位置，則需要定制一個對外部壓力敏感的真空管裝置。如果要知道在失去氣壓時的運動位置，則需定制一個返回原來位置的彈簧裝置。對于有兩個同時作用的激勵源的情形，在失去信號時，廠家設(shè)定該彈簧裝置順時針移動。在彈簧裝置回到激勵源時，廠家設(shè)定在失去氣壓或者同時失去氣壓和電流信號時，運動方向為彈簧返回的方向，但當(dāng)只失去電流信號時，運動方向與彈簧方向無關(guān)，固定為順時針方向。為改變在失去電流信號時的運動方向，采取以下步驟：1 切斷氣流的供給和電流信號2 松開固定轉(zhuǎn)動滑輪的螺絲3 旋轉(zhuǎn)轉(zhuǎn)動滑輪90度，注意橡膠墊圈不要脫落4 擰緊固定轉(zhuǎn)動滑輪的螺絲5 交換蘭色和紅色的電線，改變罐內(nèi)的連接，重新擰緊螺絲6 連通氣流供給和電流信號，重新設(shè)置反饋罐程序（見下一部分）4-11 重新設(shè)置反饋罐只有當(dāng)罐偏離出廠設(shè)置或者要改變失去電流信號時的運動方向時，這一程序才是必要的。遠(yuǎn)程位置調(diào)節(jié)器電路需要反饋罐在正確的角度，這樣當(dāng)激勵源逆著縮小規(guī)模的結(jié)束區(qū)域才能顯示正確的電壓。例如，在空氣供給連通但信號中斷時，逆著結(jié)束區(qū)域可以顯示正確的電壓。當(dāng)在安裝模式下，罐參數(shù)已經(jīng)選好時，電路本身能夠識別出動力增加時的電壓。當(dāng)罐調(diào)節(jié)合適時，罐發(fā)光二極管由持續(xù)發(fā)光變?yōu)殚W爍。為調(diào)整罐，首先通過連通空氣供給和中斷信號使激勵源移動到縮小規(guī)模的結(jié)束區(qū)域。當(dāng)它已經(jīng)在該位置時，如果彈簧返回裝置不能逆著反向停止，可以安裝一個維護盤使之固定。如果裝置是兩個同時工作，可以簡單地切斷空氣供給使之固定。重新接通電流信號，在4-20mA范圍內(nèi)任意選擇一個電流值。選擇安裝模式，按住向上按鈕直到罐二極管持續(xù)發(fā)光。松開罐的夾具螺絲，注意不要松開太多以至于脫離運送盤螺母。轉(zhuǎn)動罐直到罐發(fā)光二極管由持續(xù)發(fā)光轉(zhuǎn)為閃爍。重新擰緊夾具螺絲并連通空氣供給。如果需要維護盤，通過切斷電流信號使其移向縮小規(guī)模區(qū)域，然后在氣流供給持續(xù)的同時移動維護盤。4-12 電可擦除只讀存儲器求校錯誤每次校準(zhǔn)或設(shè)定的數(shù)據(jù)都通過遠(yuǎn)程位置調(diào)節(jié)器電流寫入電可擦除只讀存儲器。所有電可擦除只讀存儲器數(shù)據(jù)的檢驗和都經(jīng)過計算并寫入電可擦除只讀存儲器。因此，在電可擦除只讀存儲器寫入程序的過程中出現(xiàn)信號中斷，檢驗和將不會被正確寫入或者寫入不全。信號中斷后在初始化過程中，遠(yuǎn)程位置調(diào)節(jié)器會對存儲在電可擦除只讀存儲器中的數(shù)據(jù)進(jìn)行檢驗和計算。如果新計算的檢驗和與存儲的檢驗和不一致，遠(yuǎn)程位置調(diào)節(jié)器會進(jìn)入一個錯誤程序并且不啟動正常操作模式。出現(xiàn)這一情況時，發(fā)光二極管會一個接一個的發(fā)光。如果出現(xiàn)這儀情況，開始在4.3部分所講的重設(shè)程序，然后按照4.5-4.8中所介紹的方法校準(zhǔn)。4-13 選擇設(shè)計非線性曲線圖表 遠(yuǎn)程位置調(diào)節(jié)器可能操作線性或非線性設(shè)備。非線性操作是通過在遠(yuǎn)程位置調(diào)節(jié)器和低動力的遠(yuǎn)程位置調(diào)節(jié)器（如輸入電流為0mA）之間連接跳線實現(xiàn)的。當(dāng)遠(yuǎn)程位置調(diào)節(jié)器處于高動力并且連通狀態(tài)為開時，只要一直保持在高動力狀態(tài)它就可以作為一個非線性設(shè)備進(jìn)行操作。相反，當(dāng)遠(yuǎn)程位置調(diào)節(jié)器處于高動力并且連通狀態(tài)為關(guān)，或者反之亦然當(dāng)電流保持為高動力狀態(tài)將不會有從非線性操作到線性操作的變化。連接的位置只有在高動力時才是有效的。當(dāng)遠(yuǎn)程位置調(diào)節(jié)器的動力為高，跳線連通，氣流供給連通時，就可以選擇11條特性曲線中的任何一個。按SET按鈕進(jìn)入安裝模式，按UP按鈕直到CURVE LED（曲線發(fā)光二極管）持續(xù)發(fā)光，即完成選擇曲線變量。設(shè)定輸入電流信號為LCP和HCP電流信號的平均值，就可以從11條曲線中選擇需要的曲線。例如，LCP 為20mA,HCP 為20mA,則需要設(shè)定輸入電流信號為12mA.輸入信號電流設(shè)置為LCP和HCP的平均值后，按SET按鈕選擇校準(zhǔn)模式，此時CURVE LED（曲線發(fā)光二極管） 將會閃亮。默認(rèn)的曲線的中間部分是線性的，而其它曲線的該部分是非線性的。（見圖表8）如果要選擇其它曲線中的一條，按UP 或DOWN按鈕，當(dāng)遠(yuǎn)程位置調(diào)節(jié)器處于信號中間值的交叉點位置時，觀察其運動，并從圖8所定義的曲線中選出不同的曲線。每按一下按鈕就對應(yīng)下一條曲線，直到按下按鈕后沒有反應(yīng)為止。選取到想要的曲線后，按設(shè)置按鈕回到安裝模式。注釋：按UP或者DOWN選擇某一條曲線后，新選擇的曲線就存儲在電可擦除只讀存儲器中，并且在遠(yuǎn)程位置調(diào)節(jié)器離開校準(zhǔn)和安裝模式以前一直保存。每條曲線都在LCP和HCP標(biāo)度點之間。如果輸入電流低于LCP或者高于HCP，遠(yuǎn)程位置調(diào)節(jié)器就會相應(yīng)的停留在LCP或者HCP位置。事實上，將線性曲線作為缺省非線性曲線進(jìn)行選擇和當(dāng)遠(yuǎn)程位置調(diào)節(jié)器處于高動力狀態(tài)并且跳線為關(guān)時線性曲線的選擇是不一樣的。對于后者，在輸入電流低于LCP或者高于HCP時，遠(yuǎn)程位置調(diào)節(jié)器的位置會按照線性關(guān)系超出LCP或者HCP點，而前一種情況則是停留在LCP或者HCP點。4-14設(shè)置可選跨距與調(diào)零角轉(zhuǎn)播電路直接置于遠(yuǎn)程位置調(diào)節(jié)器電路的下方，雖然零點和跨距接近遠(yuǎn)程位置調(diào)節(jié)器電路中的孔洞，他們?nèi)匀豢梢酝ㄟ^小的螺絲起子隨時連接（見圖6）。連通空氣供給，遠(yuǎn)程位置調(diào)節(jié)器信號并連通角度讀卡機。若要設(shè)置零點，移動遠(yuǎn)程位置調(diào)節(jié)器到最小信號點（通常4mA）并設(shè)置零預(yù)制罐在一個期望的中繼電流值。然后，為設(shè)置跨距，將遠(yuǎn)程位置調(diào)節(jié)器移動到最大信號點（通常20mA），并且調(diào)整跨距預(yù)制罐于一個期望的中繼電流。在繼續(xù)核對和調(diào)整這兩個設(shè)置直到都正確為止，因為在調(diào)節(jié)跨距的過程中會對零點的讀數(shù)有影響，反之亦然。因此，往往要重新調(diào)整幾次。角度中繼電路安裝有跳線，如果要在45度或者更小的角度范圍內(nèi)讓電流值為420mA，跳線要恰好能夠連接兩個插腳。調(diào)節(jié)罐可以在這兩個數(shù)值之間調(diào)整。為了能更接近跳線，有必要在載波盤裝配時讓其遠(yuǎn)離遠(yuǎn)程位置調(diào)節(jié)器。說明見21415 可選底膠位監(jiān)視器位置的調(diào)節(jié)如果遠(yuǎn)程位置調(diào)節(jié)器安裝了底膠位置監(jiān)視器，則要在安裝遠(yuǎn)程位置調(diào)節(jié)器后調(diào)節(jié)底膠位置監(jiān)視器使讀數(shù)準(zhǔn)確。內(nèi)置O圈完成了粗安裝，殼內(nèi)凹槽在一定程度上對安裝起調(diào)節(jié)作用。為調(diào)節(jié)角刻度的位置，首先旋松兩個固定透明外殼與蓋子的不銹鋼螺絲，同時將外殼連同其黑色罩/指示器模具同時升起。不要讓螺絲和外殼與蓋子之間的O圈脫落。如果你顛倒了遠(yuǎn)程位置調(diào)節(jié)器的順時針和逆時針，在這一階段需要將自粘合角標(biāo)度正反調(diào)換。注意要與稱量傳送帶模具相匹配。轉(zhuǎn)動稱量傳送帶，使其沿著O圈內(nèi)部滑動。如果O圈被粘住，這樣做會有一定困難。照此移動，直到其逆著指示器/指示器模具盡可能的接近正確值。同時，應(yīng)該固定蓋子螺絲孔上方外殼中心有刻槽的位置。重新裝好螺絲，確保模具罩和密封O圈在外殼罩模具中。逆著模具螺絲轉(zhuǎn)動外殼溝槽以調(diào)整指示器的位置，直到其達(dá)到最終位置。注意將螺絲放在溝槽的等價位置，這樣殼相對于內(nèi)部轉(zhuǎn)動部分來說仍處于中心位置。然后擰緊螺絲。5

active while adjusting the DAMP setting, and continues to follow the input signal. This allows the signal to be waggled to optimize the response while still adjusting the DAMP setting. Try stepping the signal suddenly so that the positioner approaches setpoint at full speed having traveled 45 degrees or more, and adjust the DAMP setting to just avoid overshoot here. Try this traveling up and downscale. When the right setting has been found, press the SET button again to leave Adjust Mode the DAMP LED will now light continuously.4-8 LOW CURRENT POINT (LCP) AND HIGH CURRENT POINT(HCP) SETTINGSThe positioner characteristic can be accurately calibrated by setting two points,the Low Current Point(LCP)and the High Current Point(HCP).Each point is defined by a position and an input current.These points can lie anywhere in the range of travel of the actuator,and in the input signal range of 4 to 20mA.The only other restriction is that the input current at the HCP must exceed the input current at the LCPby at least 5mA.To obtain the best accuracy, it is necessary to select the two points as far apart as possible. In both linear and non-linear operation this allows forward acting, reverse acting,and forward or reverse acting split range characteristics to be implemented(4-12mA or 12-20mA for exemple).To set lcp, select the LOW parameter in Setup Mode by pressing the UP button until the LOW LED lights continuously. Press the SET button to select Adjust Mode, and the LOW LED will blink. Ajust the input signal current within the range 4-20mA to the value you want to define for the LCP-note that changes in input current within the 4-20mA band do not result in positioner movement at this stage- the positioner holds the actuator at the angle where it was before Adjust Mode was selected, irrespective of input current. Press the Up or down buttons to move the positioner to the angle you want to define for the LCP-if you hold the button down continuously, the positioner will traverse the actuator steadily, or if you give short blips it will move approximately 1/40 deg. For each blip, to allow precise edging into the required position. When the actuator is in exactly the position you want, and the signal is adjusted to exactly the value you want (this can be readjusted after the position has been set), press the SET button again to record the signal and position as the LCP,whereupon the actuator will make a small leap and then settle back to the LCP again, the positioner will return to Setup Mode, and the LOW LED will light continuously.The positioner will now respond to its input signal again.Note:As soon as the SET button is pressed,the LCP position and signal are stored in non-volatile memory, and are retained even if the positioner is deenergised before leaving Setup Mode.To set HCP, select the high parameter in setup mode by pressing the up button until the high led lights continuously. Press the set button to select adjust mode, and the high led will blink.Adjust the input signal current within the range 4-20mA to the value you want to define for the HCP-note that changes in input current within the 4-20mA band do not result in positioner movement at this stage- the positioner holds the actuator at the angle where it was before Adjust mode was selected, irrespective of input current. Press the up or down buttons to move the positioner to the angle you want to define for the HCP-if you hold the button down continuously, the positioner will traverse the actuator steadily, or if you give short blips it will move approximately 1/40 deg. For each blip, to allow precise edging into the required position. When the actuator is in exactly the position you want, and the signal is adjusted to exactly the value you want(this can be readjusted after the position has been set), press the set button again to record the signal and position as the HCP,where upon the actuator will make a small leap and then settle back to the HCP again, the positioner will return to setup mode, and the high led will light continuously. The positioner will now respond to its input signal again.Note: As soon as the set button is pressed, the HCP position and signal are stored in non-volatile memory, and are retained even if the positioner is deenergised before leaving setup mode.4-9 reversing clockwise/anticlockwise sense of the positionerThe LCP and HCP settings described in the previous section can be used with complete success to reverse the sense of the positioner, using settings such as the reverse settings listed in Table1. However,this will not change the direction of movement on loss of signal-see the next section for how to set this as desired.4-10 changing the direction of movement on loss of signalOn being deenergised with air supply still fully pressurized (ie. On disconnection of the signal, or when the signal falls below 3.5mA), the positioner moves the actuator in a direction set by the deenergised position of the servo valve. This direction of movement is independent of the LCP and HCP settings described in the sections above.Movement on loss of air pressure is unpredictable for double acting positioners if position needs to be held on loss of pressure, then it is necessary to order an external pressure sensing lockout valve assembly, and if a definite end of travel position is required on loss of pressure, then it is necessary to order a spring return unit.On double acting actuators, the unit is factory set to move clockwise(as viewed from positioner lid) on loss of signal.On spring return actuators, the unit is factory set to move in the spring return direction on loss of air, or on loss of both air and signal, but it is set to move clockwise(as viewed from positioner lid) irrespective of spring direction on loss of signal only.To change the direction of movement on loss of signal, carry out the following steps:1- Disconnect air supply and signal.2- Undo screw holding down changeover block(see Figure 6).3- Rotate changeover block 90 degress, taking care to keep rubber gasket lined up with holes in body.4- Re-tighten screw holding down changeover block.5- Swap blue and yellow wires over to reverse sense of pot connection, and re-tighten screws.6- Re connect air supply and signal, and carry out Resetting Feedback Pot procedure(see next section)4-11 resetting the feedback potThis procedure is necessary only if the pot has been moved from its factory setting, or if the direction of movement on loss of signal has been changed as instructed in the previous section.The positioner circuit needs the feedback pot to be positioned at the correct angle, such that its wiper reads the right voltage when the actuator is against its downscale endstop ie. Against the endstop it reaches when the air supply is connected , but the signal is disconnected. The circuit itself can identify this voltage when it is powered up in setup mode with the pot parameter selected when the pot is adjusted correctly, the pot led changes from lighting continuously to blinking.To set the pot, first move the actuator to the downscale endstop by connecting the air supply and disconnecting the signal. When it is in this position, hold it there by fitting a keeper plate if the unit has a spring return set to fail against the opposite stop, or by simply disconnecting the air supply if the unit is double acting or has a spring return set to fail against this stop. Re-connect the signal, and set to any current between 4 and 20mA. Select setup mode, and press the up button until the pot led lights continuously. Unclamp the pot clamp screws,taking care not to unscrew them too far such that they disengage from the nuts in the carrier plate. Rotate the pot until the pot led changes from continuous to blinking illumination. Re-tighten the clamp screws, and reconnect the air suppy. If the unit needed a keeper plate, drive it downscale by disconnecting the signal, and then remove the keeper plate with the air supply on.4-12 eeprom checksum errorEach time calibration or setting data is written to EEPROM(non-volatile memory) by the positioner circuit, a checksum of all EEPOM data is calculated and written to EEPROM. Hence if there is a power supply(ie. signal) interruption during the EEPROM write procedure, the checksum will not be written correctly, or at all. After the interruption,during its initialization routines the positioner carries out a checksum calculation of the data stored in EEPROM. If the newly calculated checksum and the stored checksum are not identical, the positioner enters an error routine, and does not start Normal Mode operation. This condition is indicated by the LEDs lighting one agter the other in sequence. If this condition is achieved, carry out the reset procedure described in section 4.3, and then recalibrate as detailed in sections 4.5 to 4.8.4-13 selecting and setting up non-linear curvesThe positioner may be operated either as a linear or non-linear device. Non-linear operation is enabled by fitting a jumper link to the positioner with the positioner (and position retransmit if fitted) powered down (ie. Input current at 0mA). When the positioner is powered up with the link “on”(see figure 6 for its position), it will then operate as a non-linear device for as long as it remails powered up. Conversely, when the positioner is powered up with the link“off” or vice-versa while the circuit remains powered up will not cause a change from non-linear to linear operation- the position of the link is only effective during power up.When the positioner is powered up with the jumper link “on” and the air supply connected, then any one of eleven characteristic curves may be selected. Press the SET button to go into Setup Mode, and select the CURVE variable by pressing the UP button until the CURVE LED lights continuously. It is easiest to select the required curve from the eleven available by setting the input signal current to m
