 误参见第6.8节张力电子设备检测到的警告和错误。6.6.2警告消息可以检测到以下警告：•Profibus通信问题•同步问题参见第6.8节张力电子设备检测到的警告和错误。张力电子设备PFEA113，用户手册第6章故障追踪6-4 3BSE029382R0101 Rev C 6.7故障症状和措施一般备注：如果自由（未屏蔽）电缆长度超过0.1 m（4 in.），则必须对电源和信号导线进行单独绞合。自由长度超过0.1 m会导致零点不稳定或测量值不正确。表6-1故障症状和措施故障症状措施噪音信号-根据电缆图检查电缆屏蔽层是否接地靠近有噪音的电缆可能会导致干扰问题。零点不稳定-检查电缆屏蔽两端是否未连接检查称重传感器和电子设备之间的电缆是否有对角对，一对用于信号电路，另一对用于励磁电路，见图2-2。-如果安装了接线盒，检查接线盒和电子设备间的称重传感器信号和称重传感器励磁是否在单独的电缆中布线。-如果两个或多个IP 20装置安装在同一机柜中，则检查它们是否同步（同步装置的电缆，见电缆图和第2.4.1.3节同步）。显示器和LED指示灯不亮。如果操作员面板显示器不亮，“电源”和“状态”指示灯亮，并且操作员面板处于“关闭”状态，请检查以下各项：-检查电缆是否正确连接到电子设备电源。-检查连接到电子设备的电源是否正确。-检查电源开关是否“打开”（在IP 65版本（NEMA 4）外壳内）。-第6.8.1.3节供应误差中描述了进一步的测试。An ERROR is something that causes the electronics to function incorrectly. A WARNING is something that might affect the accuracy of the measurement. When a warning or an error occurs, a warning or an error message is displayed on the Operator Panel and the “Status” indication turns from green to red. When is pressed the message disappears from the display. If the problem that activated the warning or error message has disappeared the “Status” indication turns to green. If the error or warning remains the “Status” indication is red. Use the to step to the last operator menu, where you can read the error or warning message. 6.6.1 Error Messages The following errors can be detected: • Flash (memory) error • EEPROM (memory) error • Supply error • Load cell excitation error See Section 6.8 Warnings and Errors Detected by the Tension Electronics. 6.6.2 Warning Messages The following warnings can be detected: • Profibus communication problem • Synchronization problem See Section 6.8 Warnings and Errors Detected by the Tension Electronics. Tension Electronics PFEA113, User Manual Chapter 6 Fault-tracing 6-4 3BSE029382R0101 Rev C 6.7 Fault Symptoms and Measures General remark: If the free (unscreened) cable length exceeds 0.1 m (4 in.) the individual pairs of power and signal conductors must be twisted. Free length exceeding 0.1 m can cause unstable zero point or incorrect absolute measurement value. Table 6-1.
