快速設(shè)置指導(dǎo)您完成設(shè)置張力電子設(shè)備的最少步驟。
要求您回答一些問題并輸入所需的值。這些選擇和必須進(jìn)行參數(shù)設(shè)置，以使張力電子設(shè)備做好測量準(zhǔn)備。
在快速設(shè)置中僅設(shè)置有限數(shù)量的選擇和參數(shù)設(shè)置。所有其他參數(shù)設(shè)置為出廠默認(rèn)值。見附錄A.4出廠默認(rèn)設(shè)置。
根據(jù)包裹增益的設(shè)置方式，可以通過兩種方式進(jìn)行快速設(shè)置。
可通過選擇“懸掛重量”或“輸入包裹增益”來設(shè)置包裹增益。

懸掛重量和包裹增益在第3.12.5節(jié)中解釋。檢查稱重傳感器信號極性這是一種檢查稱重傳感器是否連接以提供正輸出的簡單方法張力電子設(shè)備的信號變化，導(dǎo)致卷筒紙張力增加。
1、用手推動，在一個負(fù)載上施加與增加的腹板張力相對應(yīng)的力一次測量一個傳感器（盡可能靠近稱重傳感器），并檢查顯示讀數(shù)是否為積極樂觀的如果顯示讀數(shù)為負(fù)值，則將稱重傳感器信號連接反向至張力電子設(shè)備。
如果你不知道力的作用方向，以相同的力方向連接稱重傳感器A和B。
要改變稱重傳感器A的極性，請反轉(zhuǎn)X1:5和6（在A+和A-）。要更改稱重傳感器B的極性，請反轉(zhuǎn)X1:9和10（在B+和B-）。
2、改變稱重傳感器極性后，檢查顯示屏讀數(shù)是否為正值腹板張力。
3.10檢查稱重傳感器功能“懸掛重量”程序也可用作稱重傳感器的功能測試，稱重傳感器。應(yīng)注意輸出信號，繩索應(yīng)靠近另一根繩索移動
稱重傳感器。檢查輸出信號的差異是否很小。
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.
