However, local statutory regulations, if stricter, are to take precedence.在開始任何安裝工作之前，需仔細(xì)閱讀并遵守第1章的安全須知。NOTE 注意All personnel working with the installation must know the location of the main power supply switch to the measurement system and how it is operated.所有安裝人員須了解本地電源開關(guān)到測量系統(tǒng)的接線（原意是本地電源開關(guān)到測量系統(tǒng)，怎樣操作） Equipment Safety 設(shè)備安全CAUTION小心Always switch off the mains supply voltage to the measurement system before replacing a unit.更換單元時要切斷測量系統(tǒng)的主電源?！?PFEA112 provides the same functionality and user friendliness as the PFEA111 with the addition of fieldbus munication via ProfibusDP.PFEA112和PFEA111一樣，只是增加了ProfibusDP局域網(wǎng)通訊。hapter 1 Introduction第一章 緒論 About this manual 關(guān)于此手冊 This User Manual describes your new Measure Web Tension System. When you have read the manual, you will have the necessary knowledge for mechanical and electrical installation, missioning, operation, preventive maintenance and basic fault tracing of your measurement system.。該裝置可以很方便地安裝在電氣柜的DIN導(dǎo)軌上。DANGER危險Switch off and lock the mains operating switch to the tension electronics before performing any work on the tension electronics. When the work is pleted, check that there are no loose wires, and that all units are properly secured.在裝置運(yùn)行前須切斷和鎖定主操作開關(guān)，當(dāng)工作結(jié)束后檢查是否有松動的電纜以及整個單元都是否安全。該設(shè)備是精密儀器，必須小心處理。 Between the junction box and the tension electronics, signal and excitation must be routed in separate cables. For example: For example: a 2 mm cable for the excitation and a shielded 22 mm cable with twisted pair cores for the load cell signals.接線盒到張力測量裝置的信號和勵磁電纜必須分開，例如：一根22。 The enclosure is fitted with six cable glands. 隔離柵配有6個走線密封管Inches (英寸) for cable 走線孔 mounting holes 安裝孔Connect the cables to terminals according cable diagrams in Appendix (B, C, D, or E) depending on installed load type.參照附錄 (B, C, D, or E) 中接線圖連接電纜到接線端子NOTE (注意)Do not connect solid conductors to terminals. Do not crimp pins to stranded cores.固體導(dǎo)體不直接連接在接線端子上，不要卷折插腳成多股芯。：隔離放大器PXUB201。Steps up in a list. 在一個目錄里選擇向上。這些數(shù)據(jù)要根據(jù)測量參數(shù)而建立。如果顯示為負(fù)信號，顛倒壓頭與張力測量裝置之間的連線。該兩項設(shè)定后才能進(jìn)行后續(xù)的設(shè)定，語言和（計量）單位在取鑰匙可更改。 Safety Instructions (安全說明) Read and follow the safety instructions stated in Chapter 1 Introduction, before starting any missioning work. However, local statutory regulations, if stricter, are to take precedence.閱讀理解第1章緒論中安全指導(dǎo)規(guī)定，在以任何一種方式試車操作以前，本地的相關(guān)規(guī)定如果嚴(yán)密，那么以它優(yōu)先。Since the signal earth of the measurement system is connected to the chassis earth of the tension electronics, the input of a superior system connected to the control system must not be earthed. The best ways of interconnecting the measurement system and a superior system to achieve optimal function are shown in Figure 26 and Figure 27.電纜屏蔽必須接通大地。Synchronization is done by interconnecting the “SYNC” terminals, screw terminal X1:14, of all the units and interconnecting screw terminal X:15 of all units. A twisted pair cable or a screened cable must be used.同步是由內(nèi)部SYNC端子完成的，用一根雙絞或屏蔽電纜把所有裝置的X1:14和X1:15分別連在一起。這個電壓信號相對強(qiáng)的壓力傳感器的信號張力測量裝置轉(zhuǎn)換成一個系統(tǒng)的輸出。The tension measurement system contains no moving parts. However, the load cells are mounted close to a rotating roll over which a web is running.張力測量系統(tǒng)沒有任何移動部件。 About this System (關(guān)于這個系統(tǒng))Your system for tension measurement consists of:張力測量系統(tǒng)由以下構(gòu)成: How to use this manual 怎么使用手冊This user manual prises two main parts.此用戶手冊有兩個主要部分。— PFEA112提供和PFEA111同樣的功能用戶也容易理解，它們的指令通過ProfibusDP進(jìn)行傳輸。 ABB’s Pressductor transducer technology produces a signal as a result of changes in an electromagnetic field when the load cell is subjected to mechanical force. It is an operating principle that has its origin in a metallurgical phenomenon according to which mechanical forces alter the ability of some steels to convey a magnetic field. Unlike other types of load cell technologies, physical movement such as pression, bending or stretching is not required for signal generation.當(dāng)一個機(jī)械力作用于ABB的 Pressductor壓力傳感器時，將引起傳感器內(nèi)部磁場會發(fā)生變化從而產(chǎn)生一個信號。 Appendix C PFTL 301EDesigning the Load Cell Installation The external protective earth (PE) cable must be attached to one of the earth bar screw clamps. The main supply voltage for all the three power supply units are:主要電源電壓是為了第3電源單元 X indicates a numerical value.
