ABB PFEA111-20 3BSE050090R20 負(fù)載上測得的力之間的比率

以下規(guī)則適用于機(jī)柜的定位和定位:
?機(jī)柜頂面與屋頂、梁底面或
通風(fēng)管道等必須至少為250 mm。如果電纜從上方進(jìn)入,則該距離為
增加到1000毫米。
?機(jī)柜后部和墻壁之間必須有至少40 mm的間隙,
以及在櫥柜的側(cè)面和墻壁之間。
?允許帶鉸鏈的框架或外部封裝的門在沒有鉸鏈的情況下完全打開
在相鄰的墻壁上,到墻壁的距離必須增加到500毫米
框架的鉸鏈側(cè)(左側(cè))或車門鉸鏈側(cè)(右側(cè))300 mm。
?機(jī)柜前面必須有至少1米的可用空間。必須有可能
完全打開門,以免限制退房和服務(wù)。
為了能夠在顯示器上顯示實(shí)際的卷材張力,卷材張力和
必須確定稱重傳感器上測得的力。
這個(gè)比例是一個(gè)稱為“包裹增益”的比例因子。
包裹增益取決于卷材在測量輥上的包裹角度和
稱重傳感器。因此,包裹增益取決于實(shí)際安裝。
這樣可以:
T(張力)=包裹增益×FR(稱重傳感器測量方向上的卷材張力)
有兩種方法可以找出腹板張力和負(fù)載上測得的力之間的比率
單元格,通過懸掛重量或通過計(jì)算。
?帶懸掛重物(菜單懸掛重物)
沿著腹板路徑準(zhǔn)確地系上一根繩子,并施加已知的重量。
施加的已知重量模擬實(shí)際的卷材張力和電子測量
由施加的重量引起的稱重傳感器上的合力。
當(dāng)幅材張力(T)和相應(yīng)的測量力(FR)都已知時(shí)
張力電子設(shè)備計(jì)算比值T/FR,并將該值存儲(chǔ)為包裹增益。
當(dāng)卷筒紙張力施加到卷筒上時(shí),張力電子設(shè)備通過以下方式計(jì)算卷筒紙張力
將測得的稱重傳感器上的力與“包裹增益”相乘。
在懸掛重量程序之后,由張力電子設(shè)備計(jì)算的包裹增益可以
可在EnterWrapGain菜單中找到。

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.?
