ABB PFEA111-20 3BSE050090R20 负载上测得的力之间的比率

以下规则适用于机柜的定位和定位：

•机柜顶面与屋顶、梁底面或

通风管道等必须至少为250 mm。如果电缆从上方进入，则该距离为

增加到1000毫米。

•机柜后部和墙壁之间必须有至少40 mm的间隙，

以及在橱柜的侧面和墙壁之间。

•允许带铰链的框架或外部封装的门在没有铰链的情况下完全打开

在相邻的墙壁上，到墙壁的距离必须增加到500毫米

框架的铰链侧（左侧）或车门铰链侧（右侧）300 mm。

•机柜前面必须有至少1米的可用空间。必须有可能

完全打开门，以免限制退房和服务。

为了能够在显示器上显示实际的卷材张力，卷材张力和

必须确定称重传感器上测得的力。

这个比例是一个称为“包裹增益”的比例因子。

包裹增益取决于卷材在测量辊上的包裹角度和

称重传感器。因此，包裹增益取决于实际安装。

这样可以：

T（张力）=包裹增益×FR（称重传感器测量方向上的卷材张力）

有两种方法可以找出腹板张力和负载上测得的力之间的比率

单元格，通过悬挂重量或通过计算。

•带悬挂重物（菜单悬挂重物）

沿着腹板路径准确地系上一根绳子，并施加已知的重量。

施加的已知重量模拟实际的卷材张力和电子测量

由施加的重量引起的称重传感器上的合力。

当幅材张力（T）和相应的测量力（FR）都已知时

张力电子设备计算比值T/FR，并将该值存储为包裹增益。

当卷筒纸张力施加到卷筒上时，张力电子设备通过以下方式计算卷筒纸张力

将测得的称重传感器上的力与“包裹增益”相乘。

在悬挂重量程序之后，由张力电子设备计算的包裹增益可以

可在EnterWrapGain菜单中找到。

The following rules apply to locating and positioning of the cabinet:

• The distance between the top surface of the cabinet and the roof, soffit of a beam or

ventilation duct etc. must be at least 250 mm. If cables enter from above, this distance is

increased to 1000 mm.

• There must be a clearance of at least 40 mm between the rear of the cabinet and the wall,

and between the sides of the cabinet and the wall.

• To permit a frame with hinge, or a door to an outer encapsulation to open fully without

catching on the adjacent wall, the distance to the wall must be increased to 500 mm on the

hinge side (left) of the frame, or 300 mm on the hinge side (right) of the door.

• There must be at least 1 meter of free space in front of the cabinet. It must be possible to

open the door completely, in order not to restrict access for check-out and servicing.

To be able to present actual web tension on the display, the ratio between web tension and

measured force on the load cell must be determined.

This ratio is a scaling factor called Wrap Gain.

The Wrap Gain depends on the web's wrap angle on the measuring roll and the orientation of the

load cells. Therefore, Wrap Gain depends on the actual installation.

This gives:

T (tension) = Wrap Gain × FR (force of web tension in load cell measuring direction)

There are two ways to find out the ratio between web tension and measured force on the load

cells, by Hanging weights or by Calculation.

• With hanging weights (Menu HangWeight)

String a rope that follows the web path exactly and apply a known weight.

The applied known weight simulates the actual web tension and the electronics measures

the resulting force on the load cells caused by the applied weight.

When both web tension (T) and the corresponding measured force (FR) are known the

tension electronics calculates the ratio T / FR and stores the value as Wrap Gain.

When web tension is applied to the roll the tension electronics calculates web tension by

multiplying the measured force on the load cells with the Wrap Gain.

After the hanging weight procedure the wrap gain calculated by the tension electronics can

be found in the EnterWrapGain menu.
