使用上下鍵從列表中選擇對象類型[ZZ]。第1卷：標準卷（稱重傳感器A和B）、單側(cè)A或單側(cè)B（稱重傳感器A或B）第2卷：標準卷（稱重傳感器C和D）、單面C或單面（稱重傳感器C或D）當選擇單側(cè)測量時，測量信號乘以2和在顯示器和模擬輸出上顯示為卷筒紙張力。設(shè)置分段滾動的對象類型對象類型SegmentedRoll最多可用于連接到一個、兩個或多個傳感器的12個稱重傳感器三個張力電子元件PFEA113。
B&R 7EX470.50-1總線控制器每個PFEA113必須設(shè)置為：?一個輸入（稱重傳感器連接到A）?兩個輸入（連接到A和B的稱重傳感器）?三個輸入（連接到A、B和C的稱重傳感器）或?四個輸入（連接到A、B、C和D的稱重傳感器）分段滾動比例因子（SRSF）用于補償總測量張力和當并非所有輥都由分段式稱重傳感器支撐時，給出總張力的估計值滾動應(yīng)用。有關(guān)SRSF的計算，請參閱。連接多個電子設(shè)備（兩個或三個PFEA113連接在一起）模擬輸入AI1和AI2（見圖3-10）用于連接兩個或三個PFEA113電子產(chǎn)品在一起。下面的配置示例基于圖3-10。如果選擇N/m、kN/m、kg/m或pli作為表示單位，則必須輸入總腹板寬度這三種電子產(chǎn)品。必須在所有三個電子設(shè)備中輸入相同的包裹增益值。如果使用比例因子SRSF，則必須計算SRSF，并分別為每個SRSF設(shè)置電子裝置，另見附錄A.3張力電子裝置PFEA113的技術(shù)數(shù)據(jù)。1.PFEA113（1）和PFEA113（2）上模擬輸出（AO）的配置規(guī)則連接到PFEA113（3）上的AI1和AI2：–選擇電壓輸出，因為AI1和AI2只能連接到電壓信號。–使用連接信號替代方案，該替代方案包括要連接到輸出的稱重傳感器信號，請參閱第3.12.7節(jié)。–將過濾器設(shè)置設(shè)置為5毫秒（最短的可選擇時間）–設(shè)置高張力（N、kN、kg、lbs、N/m、kN/m、kg/m或pli）和高輸出（V）。
Use up and down keys to select type of object [ZZ] from list.
Roll 1: StandardRoll (load cells A and B), SingleSideA or SingleSideB (load cell A or B)
Roll 2: StandardRoll (load cells C and D), SingleSideC or SingleSideD (load cell C or D)
When single side measurement is selected the measured signal is multiplied by two and
presented as web tension on display and analog output.Setting Object Types for Segmented Roll
Object type SegmentedRoll can be used for up to 12 load cells that are connected to one, two or
three Tension Electronics PFEA113.
Each PFEA113 must be set up for:
? one input (load cell connected to A)
? two inputs (load cells connected to A and B)
? three inputs (load cells connected to A, B and C) or
? four inputs (load cells connected to A, B, C and D)Segmented Roll Scale Factor (SRSF) is used to compensate the total measured tension and
present an estimate of total tension when not all rolls are supported by load cells in a segmented
roll application. For calculations of SRSF, refer to.Connecting Multiple Electronics (two or three PFEA113 connected together)
Analog inputs AI1 and AI2, see Figure 3-10, are used for connecting two or three PFEA113
electronics together. The configuration example below is based on Figure 3-10.
If N/m, kN/m, kg/m or pli is chosen as presentation unit, the total web width must be entered in
all three electronics.
The same wrap gain value must be entered in all three electronics.
If the scale factor SRSF is used, the SRSF must be calculated and set separately for each
electronic unit, see also Appendix A.3 Technical Data for Tension Electronics PFEA113.
1. Configuration rules for analog outputs(AO) on PFEA113 (1) and PFEA113 (2) to be
connected to AI1 and AI2 on PFEA113 (3):
– Choose voltage output, since AI1 and AI2 can only be connected to voltage signals.
– Use the ConnectSignals alternative that includes the load cell signals you want to connect to the output, see Section 3.12.7.
– Set the filter settings to 5 ms (the shortest selectable time).
– Set HighTension (N, kN, kg, lbs, N/m, kN/m, kg/m or pli) and HighOutput (V).
