故障追踪程序
故障症状机械安装机械安装故障通常表现为零点不稳定或灵敏度不正确。如果故障与工艺参数（如温度）相关，或可能与特定操作相关，则故障很可能来自设备的机械部分。称重传感器称重传感器的校准数据不会逐渐变化。根据其尺寸和类型，测压元件可以承受测量方向上五（1）倍标称载荷。生产线中的事件，如卷筒纸断裂，可能会导致超载大到足以改变称重传感器数据。根据过载量的不同，它可能足以设置为零。（1） 请参阅附录B、C、D或E中有关称重传感器类型过载能力的更多信息。电缆故障或零点不稳定等布线问题可能由电缆或接线故障引起。靠近嘈杂的电缆可能会导致干扰问题。不正确的安装，如电缆芯不对称连接或屏蔽两端接地，而不是仅一端接地，可能会显示为不稳定的零点。如果称重传感器信号的极性不正确，则必须检查布线。张力电子设备间歇性功能丧失通常是由于张力电子设备的故障造成的。不稳定性问题很少源自张力电子设备。连接到张力电子设备的设备故障可能会影响其操作。
警告是可能影响测量精度的东西
PFEA111/112中的错误和警告信息错误是指导致电子设备无法正常工作的原因。警告是可能影响测量精度的东西。当出现警告或错误时，操作员面板上将显示警告或错误消息，“状态”指示从绿色变为红色。按下时，消息将从显示屏上消失。如果激活警告或错误消息的问题消失，“状态”指示变为绿色。如果错误或警告仍然存在，则“Status”（状态）指示为红色。使用转至最后一个操作员菜单，您可以在其中读取错误或警告消息。1错误信息可检测到以下错误：•闪存（存储器）错误•EEPROM（存储器）故障•电源故障•称重传感器励磁故障参见第节张力电子设备检测到的警告和错误。2警告信息可检测到以下警告：•Profibus通信问题•同步问题参见第节张力电子设备检测到的警告和错误
Fault tracing procedure
Fault symptom Mechanical installation Mechanical installation fault usually shows unstable zero point or incorrect sensitivity. If the fault is related to process parameters (such as temperature) or may be related to a specific operation, it is likely that the fault is from the mechanical part of the equipment. The calibration data of the load cell will not change gradually. Depending on its size and type, the load cell can withstand five (1) times the nominal load in the direction of measurement. Events in the production line, such as web breaking, may cause overloads large enough to change the load cell data. Depending on the overload, it may be sufficient to set to zero. (1) Refer to Appendix B, C, D, or E for more information on load cell type overload capabilities. Wiring problems such as cable failure or unstable zero point may be caused by cable or wiring failure. Proximity to noisy cables may cause interference problems. Improper installation, such as asymmetric connection of cable core or grounding of shield at both ends, rather than grounding at only one end, may indicate unstable zero point. If the polarity of the load cell signal is incorrect, the wiring must be checked. Intermittent loss of function of tension electronic equipment is usually caused by failure of tension electronic equipment. Instability problems rarely arise from tension electronics. Failure of the equipment connected to the tension electronics may affect its operation.
Warning is something that may affect the measurement accuracy
The errors and warning information errors in PFEA111/112 refer to the causes that cause the electronic equipment to fail to work properly. Warning is something that may affect the measurement accuracy. When a warning or error occurs, a warning or error message is displayed on the operator panel, and the "Status" indication changes from green to red. When pressed, the message will disappear from the display. If the problem that activated the warning or error message disappears, the Status indicator turns green. If the error or warning still exists, the "Status" indication is red. Use to go to the last operator menu where you can read error or warning messages. 1 Error message The following errors can be detected: • Flash memory error • EEPROM failure • Power failure • Load cell excitation failure See section Warnings and errors detected by tension electronics. 2 Warning messages The following warnings can be detected: • Profibus communication problems • Synchronization problems See section Warnings and errors detected by tension electronics
