NI SCXI-1326电压模块,SCXI-1326使用尺寸
快速设置指导您完成设置张力电子设备的最少步骤。
要求您回答一些问题并输入所需的值。这些选择和必须进行参数设置,以使张力电子设备做好测量准备。
在快速设置中仅设置有限数量的选择和参数设置。所有其他参数设置为出厂默认值。见附录A.4出厂默认设置。
根据包裹增益的设置方式,可以通过两种方式进行快速设置。
可通过选择“悬挂重量”或“输入包裹增益”来设置包裹增益。

悬挂重量和包裹增益在第3.12.5节中解释。检查称重传感器信号极性这是一种检查称重传感器是否连接以提供正输出的简单方法张力电子设备的信号变化,导致卷筒纸张力增加。
1、用手推动,在一个负载上施加与增加的腹板张力相对应的力一次测量一个传感器(尽可能靠近称重传感器),并检查显示读数是否为积极乐观的如果显示读数为负值,则将称重传感器信号连接反向至张力电子设备。
如果你不知道力的作用方向,以相同的力方向连接称重传感器A和B。
要改变称重传感器A的极性,请反转X1:5和6(在A+和A-)。要更改称重传感器B的极性,请反转X1:9和10(在B+和B-)。
2、改变称重传感器极性后,检查显示屏读数是否为正值腹板张力。
3.10检查称重传感器功能“悬挂重量”程序也可用作称重传感器的功能测试,称重传感器。应注意输出信号,绳索应靠近另一根绳索移动
称重传感器。检查输出信号的差异是否很小。
Checking Load Cell Signal Polarity
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.
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.
NOTE
If you don’t know in which direction the force is acting,
connect load cell A and B with the same force direction.
To change the polarity of load cell A, invert X1:5 and 6 (In A+ and In A-).
To change the polarity of load cell B, invert X1:9 and 10 (In B+ and In B-).
2. After changing load cell polarity, check that the display reading is positive for increased
web tension.
3.10 Checking Load Cell Function
The “Hanging Weight” procedure can also be used as a function test on load cells,
see Section 3.8.1.
The rope should then be placed in the web path but as close as possible to one of the
load cells. The output signal should be noted, and the rope moved close to the other
load cell. Check that the difference in output signal is small.
