ABB传感器PFEA111-112中英文手册(12)

If the polarity of load cell signals is not correct, the cabling has to be checked. 如果测压单元信号极性不对，就必须检查电缆。 Tension Electronics 张力传感器

Intermittent loss of a function usually due to a fault in the tension electronics.

张力测量装置上的信号时有 Instability problems seldom originate from the tension electronics. 不稳定的问题很少因传感器引起。

Faults in devices connected to the tension electronics may affect its operation. 和传感器连接的装置的故障可能影响其操作。

6.6 Error and Warning Messages in PFEA 111/112 PFEA111/112的错误和警告信息 An ERROR is something that causes the electronics to function incorrectly. ERROR导致传感器功能错误。

A WARNING is something that might affect the accuracy of the measurement. WARNING可能影响测量精度。

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.

当警告或错误出现，其信息在操作面板显示同时“状态”从绿变红。 When √ is pressed the message disappears from the display. 当√按下信息将从显示器消失。

If the problem that activated the warning or error message has disappeared the “status” indication turns to green.

如果导致警告和错误信息的问题已经消失，“状态”变绿。

If the error or warning remains the “status” indication is red. Use the DOWN to step to the last operator menu, where you can read the error or warning message.

如果错误或警告仍然是红，使用DOWN到主菜单，那儿您可以读到错误或警告信息。 6.6.1 Error Messages 错误信息 The following errors can be detected: 下列错误可以忽略：

? Flash (memory) error闪动

? EEPROM (memory) error存储器错误 ? Supply error供给错误

? Load cell excitation error测压单元激发错误

See Section 6.8 Warning and Errors Detected by the Tension Electronics. 6.6.2 Warning Messages 警告信息 The following warning can be detected: 下列警告信息可忽略：

? Profibus communication problem Profibus通讯问题 ? Synchronization problem 同步问题

See Section 6.8 Warning and Errors Detected by the Tension Electronics. 参阅6.8章节由传感器发现的警告和错误。

67 Fault Symptoms and Measures 故障症状和调节 General remark: 一般说明

If the free (unscreened) cable length exceeds 0.1 m (4 in.) the individual pairs of power and signal

26

conductors must be twisted.

如果非屏蔽电缆的长度超过0.1m单独的一对电源和信号必须缠绕在一起。

Free length exceeding 1.0 m can cause unstable zero point or incorrect absolute measurement value. 长度超过1.0m的非屏蔽电缆可能导致不稳定的零点或不正确的绝对测量值。

Table 6-1 fault symptoms and measures

表6-1 故障症结和措施

Fault symptom故障症结 measures措施

Noisy signals - Check that cable shields are connected to earth according to cable diagram. 噪音信号 - Proximity to noisy cables can cause interference problems. 检查电缆护罩依照图表连接到地。

接近噪声电缆可能导致相互干扰的问题。

Unstable zero point - Check that cable screens are not connected in both ends. 不稳定的零点 检查电缆屏蔽没有两端相连。

- check that cable between load cell and electronic has diagonal pairs, one pair for signal circuit and one par for excitation circuit, see figure 2-2. 检查测压单元和传感器之间的电缆有一定的角度。一路信号回路和一个同样的激励回路。

- Check, if a junction box is installed, that load cell signal and load cell

excitation between junction box and electronics are routed in separate cables.

如果一个接线盒已经安装，测压单元信号和激励在接线盒和传感器之间选用独立的电缆。

- Check, if two or more IP 20 units are mounted close to each other in the

same cabinet, that they are synchronized (cable for synchronizing the units, see cable diagram and section 2.4.1.3 synchronization). 如果两个或更多IP20单元在相同的橱柜里安装，那么他们是同步的。

Display and LED If the Operator panel display is not illuminated and the “Power” and

Indicators are not “Status” indications on the Operator Panel are “OFF”, check the following: Illuminated 如果操作面板显示器不亮，电源和状态指示关闭，检查以下：

显示器和LED - Check that the cables are correctly connected to the electronics power 指示不亮 supply.

检查电缆正确的连接到传感器的电源提供端。

- Check that the power supply connected to the electronics is correct. 检查电源连接到传感器是正确的。

- Check that the power switch is “ON” (inside the IP 65-version (NEMA 4)

enclosure).

确保电源开关处在开的位置。

- If power supply SD 82x is used as power supply for PFEA 111/112 IP

20-version (unsealed), check that the mains voltage selection switch on SD 82x is set to correct position (115 or 230) corresponding to the connected mains supply voltage.

如果PFEA 111/112 IP 20- version的电源由SD82x提供，检查主电压开关在正确位置接通。

- Further testes are described in Section 6.8.1.3 Supply Error.

更深的测试在6.8.1.3节里提供。

No signal when load 1. Check that cables to the electronics are correctly connected. is applied 检查到传感器的电缆是正确连接的。

负载提供而没有信号 2. Check that the load cells are connected with correct polarity. If not, the load cell signals cancel out each other. This is displayed on the operator panel as described below:

检查压头的极性是否正确，如果接反，信号将相互抵消，操作显示屏将显示如下信息： …… 此处隐藏：2495字，全部文档内容请下载后查看。喜欢就下载吧 ……
