Also check that there is enough working space in front of the enclosure.在選擇安裝地點時，需留出打開蓋子的空間，同時還得檢查裝置前面是否有足夠的操作空間。信號電纜和電源電纜需分別雙絞。 Connecting the Load CellsInformation for connecting the load cells is given in the appendix for each load cell type, see table below.每種壓頭連接信息詳見以下表格 Type of load cell (測壓元件類型) Cable diagrams in Appendix (附錄中的接線圖) Connecting Optional Units (套管選擇) Insulation Amplifier PXUB 201 (only for the IP 20version) (隔離放大器)Insulation amplifier PXUB 201 is used when galvanic insulation between input and output, or between power supply and input/output, is required. See Section Insulation Amplifier PXUB201.當輸入和輸出或電源盒輸入輸出需要絕緣就需要使用隔離放大器。Chapter 3 Commissioning （調試） About this Chapter（簡介） This chapter contains necessary information for missioning your web Tension System. It is assumed that the Web Tension System has been installed according to the instructions given in Chapter 2 Installation and Appendix (B, C, D or E) depending on installed load cell type。 Service tools (維修工具) Using the Panel Buttons (面板按鍵) Navigating and Confirming (操作確認)Display (顯示器) Button (按鍵)Steps back to previous menu. Sometimes you must press this button two or more times to get back to the desired menu.返回至上級菜單，有時你可以按這個按鍵2次或更多次來恢復你所需要的菜單。If you have pressed√ so that the parameter is placed within brackets, you can cancel the entering mode by pressing . The selections you have done with ↑ and ↓ will not be stored. If is pressed the old value is displayed without brackets.如果你已經按下√，參數(shù)放置在括號中，通過按下鍵你可以取消輸入模式；選擇你不想儲存的，如果按下舊的數(shù)據(jù)顯示就沒有括號。按裝置的提問輸入需要的數(shù)據(jù)。Figure 31 Setting Wrap Gain with Hanging Weights (example of installation)圖31 懸掛砝碼設置增益（安裝范例）Follow the steps below to run a fast setup using hanging weights.跟隨下面步驟利用懸掛砝碼執(zhí)行快速設置1 Web Tension Press√ for 5 seconds to go to the FastSetUp menu.幅面張力 按下√5秒進入FastSetUp菜單2 Fast SetUp Press√ to start the fast setup sequence. 快速設置 按下√開始快速設置順序3 SetWrapGain Select HangingWeights from the list with↑and↓Confirm with√ 設置增益 選擇HangingWeights（懸掛砝碼）按下√確定4 CellsOnRoll Select the number of load cells that support the roll (1or2) from the list 軋輥單元 with ↑or↓ Confirm with √ ↑或↓選擇對于測壓元件支撐的軋輥號碼 按√確定。NOTE（注意）If you don’t know in which direction the force is acting,如果你忘記了那些指導強制動作Connect load cell A and B with the same force direction.連接壓頭A和B與強制指示一致To change the polarity of load cell A, invert X1:5 and 6 (In A+ and In A)改變壓頭A極性，顛倒X1:5和6To change the polarity of load cell B, invert X1:9 and 10(In B+ and In B)改變壓頭B極性，顛倒X1:9和102. After changing load cell polarity, check that the display reading is positive for increased web tension.在替換壓頭極性以后，檢查是否增強紙幅張力使顯示讀數(shù)為正。 Using Wrap Gain, see Section 利用增益， Performing Fast Setup using Hanging Weights (利用懸掛砝碼實現(xiàn)快速設定)The simplest method to set the wrap gain in this tension system is to use a known weight that loads the center of the roll with a rope that follows the web path exactly.簡單的方法設定這個壓力系統(tǒng)增益，利用一個已知砝碼做負載，用繩索連接它和軋輥中心，使兩邊繩索距離相等。Select desired language from the list with↑and↓.English is set as default .用↑和↓在列表中選擇想要的語言，英語是默認值。 X indicates a numerical value.

If one unit is turned off or removed the remaining units are still synchronized.如果一套裝置斷電或拆離，剩下的裝置任然保持同步。 Solid conductors should not be connected to terminals. Pins should not be crimped to stranded （絞成股）cores.固體導體不直接連接在接線端子上， Appendix C PFTL 301EDesigning the Load Cell Installation（如圖）Chapter 2 Installation (第2章 安裝) About this Chapter The way you install your system has more influence on its functionality, accuracy and reliability than you might think. The more accurate the installation, the better the measurement system. By following the instructions in this chapter, you will fulfill the most important requirements for proper mechanical and electrical installation.The equipment is a precision instrument which although intended for severe operating conditions, must be handled with care.安裝系統(tǒng)的方法會意想不到地影響功能、精度和可靠性。 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.當一個機械力作用于ABB的 Pressductor壓力傳感器時，將引起傳感器內部磁場會發(fā)生變化從而產生一個信號。測壓元件也安在一個旋轉的輥上。— 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進行傳輸。 Tension Electronics（壓力傳感器）PFEA111 or PFEA112張力測量裝置PFEA111 or PFEA112— PFEA111 is a cost effective pact and user friendly tension electronics providing an accurate and reliable fast analog SUM signal from two load cells for control and/or monitoring.
