ABB传感器PFEA111-112中英文手册(6)

快速设置（方法）将使用最少的步骤来设定张力测量装置。按装置的提问输入需要的数据。这些数据要根据测量参数而建立。

Only a limited number of selections and parameter settings are set in the fast setup. All other parameters are set as factory default values. See Appendix A.4 Factory Default Settings. 快速设定只能设置有限的选项和参数，其他参数是出厂默认值。

The fast setup can be made in two ways, depending on how the wrap gain is set. 快速设定有两个方法，按照包角增益.

The wrap gain can be set by selecting “Hang Weight” or “Enter Wrap gain is set”. 增益可设置为悬挂砝码或键入增益并固定。 · Using Hanging Weights, see Section 3.8.1 利用悬挂砝码，参考3.8.1节

· Using Wrap Gain, see Section 3.8.2 利用增益，参考3.8.2节

3.8.1 Performing Fast Setup using Hanging Weights (利用悬挂砝码实现快速设定)

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.

简单的方法设定这个压力系统增益，利用一个已知砝码做负载，用绳索连接它和轧辊中心，使两边绳索距离相等。

Weight（砝码） Load cell supported roll (压力传感器支撑的轧辊) Rope (绳索)

All rolls must be free turning idlers. To keep friction losses low, only use the closest rolls to define web path.

所有轧辊必须能自由旋转，保持摩擦损失最底，最好利用最靠近的轧辊路径。 Figure 3-1 Setting Wrap Gain with Hanging Weights (example of installation)

3.9 Checking Load Cell Signal Polarity (核对压头信号极性)

This is a simple method to check that the load cells are connected to give a positive output signal change from the tension electronics for increased web tension. 这是一个简易的方法核对压头，接通压力电子仪器正极查看因为幅面张力增加而改变的信号输出。

1. Push with your hand to apply a force corresponding to increased web tension on one load cell at a

time (as close to the load cell as possible) and check if the display reading is positive. If the display reading is negative, invert the load cell signal connection to the tension electronics. 每次在一个压头上，用你的手推动产生一个相当于增强幅面张力的强制力，检查是否显示读数为正信号。如果显示为负信号，颠倒压头与张力测量装置之间的连线。 NOTE（注意）

If you don’t know in which direction the force is acting, 如果你忘记了那些指导强制动作

Connect load cell A and B with the same force direction. 连接压头A和B与强制指示一致

To change the polarity of load cell A, invert X1:5 and 6 (In A+ and In A-) 改变压头A极性，颠倒X1:5和6

To change the polarity of load cell B, invert X1:9 and 10(In B+ and In B-) 改变压头B极性，颠倒X1:9和10
