GCC960C102系统模块
带Pressductor®称重传感器的卷筒纸/条带张力计系统非常可靠，且不需要日常维护。作为预防措施，应定期对所有零件进行检查易受机械磨损。
5.2预防性维护检查安装螺钉，必要时拧紧。应检查称重传感器和板之间的间隙，以确保它们不会堵塞带有污垢，导致分路力通过称重传感器。如有必要，用压缩空气清洁间隙。称重传感器和接线盒之间的电缆可能受到损坏，应：必要时进行检查和更换。
5.3备件
建议用户库存以下备件：
•一个类型和尺寸正确的称重传感器。
•一个带电缆的连接器（用于PTFL 101A和PFTL 101B）。互换性
称重传感器经过工厂校准，可以直接用相同的另一个称重传感器进行更换
类型更换称重传感器后所需的唯一调整是控制装置中的零位调整单元
6.3故障跟踪程序
测量设备可分为四部分：
•机械安装。
•称重传感器。
•接线盒和电缆。
•控制单元（参见控制单元手册）。
故障症状指示故障所在的部位。
•机械安装中的故障通常会导致零点不稳定或灵敏度不正确。如果故障发生在过程中的其他因素之后，如温度，或可以链接对于特定的操作，它可能源于机械装置中的某些东西。
•称重传感器非常坚固，在测量方向上可承受其标称负载的五倍。如果称重传感器仍然过载，其数据已经改变，这可能是由于轧机中的事件，如卷筒纸/带材断裂。在过度过载时，首先发生的是零点偏移。
•布线故障可能导致干扰或零点不稳定等问题。一些故障可能是由于电缆附近引起干扰。不正确的安装，例如电缆不平衡或多端接地的屏蔽可能会导致零点变得不稳定。电缆易受机械磨损，应定期检查。还应检查接线盒，尤其是如果接线盒振动
•控制单元中的故障通常会导致功能间歇性丧失。

Web/strip Tensiometer Systems with Pressductor® load cells are extremely reliable and do not
require daily servicing. As a preventive measure, checks should be done periodically on all parts
subject to mechanical wear.
5.2 Preventive Maintenance
Check mounting screws and tighten if necessary.
The gaps between load cell and plates should be checked to ensure that they do not get clogged
with dirt, causing shunt force past the load cell. Clean the gaps with compressed air if necessary.
The cable between the load cell and the junction box is subjected to possible damage and should
be checked and replaced if necessary.
5.3 Spare Parts
Users are recommended to keep the following spare parts in stock:
• One load cell of correct type and size.
• One connector complete with cable (for PTFL 101A and PFTL 101B).
Interchangeability
The load cells are factory calibrated and can be replaced directly with another load cell of the same
type. The only adjustment required after load cell replacement is zero adjustment in the control
unit.
6.3 Fault Tracing Procedure
The measuring equipment can be divided into four parts:
• The mechanical installation.
• The load cell.
• The junction boxes and the cabling.
• The control unit (see the control unit manual).
The fault symptoms indicate in which part the fault lies.
• Faults in the mechanical installation often result in an unstable zero point or incorrect sensitivity.
If a fault follows something else in the process, such as temperature, or can be linked
to a particular operation, it probably originates from something in the mechanical installation.
• Load cells are extremely robust and can withstand five times their nominal load in the measuring direction. If a load cell has nevertheless been so overloaded that its data have been
altered, this is probably due to an event in the mill, such as web/strip breakage. On excessive overload the first thing that happens is that the zero point shifts.
• Problems such as interference or unstable zero point may be caused by wiring faults. Some
malfunctions may be due to the proximity of cables that cause interference. Incorrect installation, such as imbalance in a cable or screens earthed at more than one end may cause the
zero point to become unstable. Cables are subject to mechanical wear, and should be
checked regularly. The junction box should also be checked, especially if it is subject to
vibration.
• A fault in the control unit usually causes intermittent loss of a function. It is unusual for the
control unit to cause stability problems. Faults in connected units may affect the operation of
the control unit. For further details see the control unit manual.
