Profibus测量范围
Profibus测量范围（正常运行期间估计的卷筒纸张力）是一个参数
由用户输入。用户更改测量范围值后，更改称重传感器
标称负载不影响Profibus缩放。定义了低有效位的值
作为负载划分。
负荷分配
负荷分配是Profibus上使用的分辨率。负荷分配值为：
由PFEA113计算并取决于设定的测量范围。
测量范围在2001-5000范围内分为有限的几个部分。
负载划分值=一个划分，仅包含一个有效数字（1、2或5）。
Profibus多可处理–32768到+32767（216）个分区。
例1：
a、 Profibus测量范围（用户设置）=15 500 N
（正常运行期间的预计腹板张力）
b、 PFEA113计算的负荷分配=5 N
（Profibus上低有效位的值）
c、 Profibus测量范围/负载分配=15500/5=3100
（测量范围分为3100个分区）
例2：
如果示例1中的负载分配5N不够，则可以调整负载分配。
这可以通过将杂项菜单中的测量范围设置（减小）为
提供足够的负荷分配（分辨率）的值。
a、 测量范围=9000 N
（新的较低测量范围设置）
b、 PFEA113计算的新负荷分配=2 N
（Profibus上低有效位的新值）
在PFEA113中设置9000 N时，Profibus测量范围0–15500 N（分为
7750个分区）仍然可以使用。
通常情况下，无需将测量范围设置为低于估计幅材的1/3
正常操作期间的张力。
对于给定的负荷分配，可通过Profibus传输的大值为：
–大值=荷载分区x 32767

Section 3.13.5 Handling of Measurement Data through Profibus
3BSE029382R0101 Rev C 3-45
User Defined Scaling
The Profibus Measuring Range and Load Division can be adjusted according to user
preferences.
Profibus Measuring Range
Profibus Measuring Range (estimated web tension during normal operation) is a parameter
entered by the user. After the user has changed the Measuring Range value, changing Load cell
nominal load does not affect the Profibus scaling. The value of the least significant bit is defined
as Load Division.
Load Division
Load Division is the resolution that will be used on Profibus. The Load Division value is
calculated by PFEA113 and depends on the set measuring range.
The measuring range is divided into a limited number of divisions in the range 2001 - 5000.
The Load Division value = one division, contains only one significant digit (1, 2 or 5).
The Profibus can handle max. –32768 to +32767 (216) divisions.
Example 1:
a. Profibus Measuring Range (set by user) = 15 500 N
(estimated web tension during normal operation)
b. Load Division calculated by PFEA113 = 5 N
(value of least significant bit on Profibus)
c. Profibus Measuring Range/Load Division = 15500/5 = 3100
(the measuring range is divided into 3100 divisions)
Example 2:
If the Load Division, 5 N, in Example 1 is not sufficient, the Load Division can be adjusted.
This can be done by setting (decreasing) MeasuringRange in the Miscellaneous Menu to a
value that gives a sufficient Load Division (resolution).
a. Measuring Range = 9000 N
(New, lower measuring rangesetting)
b. New Load Division calculated by PFEA113 = 2 N
(New value of least significant bit on Profibus)
With the setting 9000 N in PFEA113 , the Profibus measuring range 0 – 15500 N (divided into
7750 divisions) can still be used, now with the Load Division (resolution) 2 N.
Normally, there is no need to set the measuring range lower than 1/3 of the estimated web
tension during normal operation.
The max. value that can be transmitted via Profibus, for a given Load Division, is:
– Max. value = Load Division x 32767

NOTE
After the user has changed the Measuring Range value, the only way to
return to Default scaling, is to use the function Set Factory default in the
Miscellaneous Menu.

3.14.1 Insulation Amplifier PXUB 201
The insulation amplifier is connected to the tension electronics voltage output.
S1 is normally set for voltage 1:1 ratio.
The output is selected to generate a voltage or current output by means of switch S1 and S2.
Slower response is selected by means of switch S2, position 3.
The switches are located inside the unit.
Figure 3-27. Insulation Amplifier PXUB 201
You must open the insulation amplifier to be able to set the switches S1 and S2.
1. Demount the insulation amplifier from the DIN rail.
Use a screw driver to unload the spring at the bottom of the insulation amplifier.
2. Press down the snap-locks on both sides of the insulation amplifier.
3. Pull the top lid open, until you see both the switches S1 and S2.
