Chapter 6 Fault-tracing 故障追踪
6.1 About this Chapter 关于此章
During the working life of your measurement system, events may occur that disturb it and your process. These disturbances may appear in many different ways and the reason for the fault can be difficult to find. However, disturbances similar in character can be grouped together and usually they have the same or similar sources of error.
在测量系统工作期间，需要处理许多干扰装置的问题。这些干扰是多渠道的，很难被发现。把类似的干扰归纳在一起，（会发现）通常是相同的或类似的干扰源。
The fault-tracing instructions in this chapter will help you to quickly find and correct the most common faults.
本章所阐述的故障追踪可以很快的发现和解决大部分的相同错误。 6.2 Safety Instructions 安全说明
Read and follow the safety instructions given in Chapter 1 Introduction when tracing faults. However, local statutory regulations, if stricter, are to take precedence.
故障错误时，请阅读和按照第一章的安全说明。但如果当地法规更严格，请优先。 6.3 Interchangeability 可交换性
Unit 单元 Measures方法
Tension Electronics The tension electronics PFEA 111/112 is interchangeable with a
24
张力传感器 tension electronics of the same type. A new setup is required.
PFEA 111/112张力传感器和同型号之间是可互换的。这需要重起。 Load cells The load cells are directly interchangeable with other load cells 测压单元 of the same type.

? Cable diagrams, see Appendix (B,C,D or E for) for installed load cell type图表，参照附件 ? Service tools维修工具 ? Torque wrench 转矩扳手 ? Multimeter 万用表
6.5 Fault-tracing Procedure错误追踪程序
Fault in the故障源 Fault symptoms故障征兆
Mechanical installation Faults in the mechanical installation usually manifest themselves as 机械装置 an unstable zero point or incorrect sensitivity.
If a fault is associated with a process parameter, such as the temperature, or can be
linked with a particular operation, the fault is likely to emanate from the mechanical part of the installation.
机械装置的故障一般表现为自身零点不稳定或错误的灵敏度。 如果故障和过程参数有关，如温度，或和特殊的操作联系起来，故障有可能是自身部件引起的。
Load cells Calibration data for a load cell do not change gradually. A load cell,
测压单元 depending on its size and type, can withstand up to five times the nominal load
in the measuring direction. An event in the process line, such as web breakage, may cause an overloading large enough to alter load cell data. Depending on the amount of overload, it may be sufficient to zero set.
压头的标定参数不会因时间而改变，一个压头，可以直接测量其5倍的正常负荷，这由其尺寸和型号所决定的。生产线的事故例如断带会使压头有足够大的过载，零位的调整取决于过载量。
Cabling Problems such as malfunctions or unstable zero point may arise 卷取辊
from faulty cables or wiring.
当出现故障或零点漂移可能是电缆引起的。
Proximity to noisy cables may cause interference problems. 附近如有带噪声的电缆可能引起干扰问题。
Incorrect installation, such as cable cores connected asymmetrically
or screens earthed at both ends instead or only at one end, may show up as an unstable zero point。 电缆连接不良、两端屏蔽接地代替了一端接地的，类似这种安装可能会引起零点漂移。
