LAM 810-072903-004 半导体

产品概述：

810-072903-004串行（RS-232）通信如果串行端口工作不正常，请验证以下内容： 检查接线，寻找松动的连接和断开或错误连接的电缆。 检查通信设置，810-072903-004应设置为19200波特、8个数据位、1个停止位和无奇偶校验。维修工具如果串行端口工作不正常，请查看第8章中的安装信息。验证以下内容： 检查接线，寻找松动的连接和断开或错误连接的电缆。请参阅上述串行（810-072903-004）通信故障排除。 检查Servlink是否正在运行并与控件通信。检查“监视窗口”是否正在运行。验证Servlink错误设置。如果数字显示不正确，请验证数字格式设置是否正确。810-072903-004有关详细信息，请参阅第8章（维修工具）。

810-072903-004报警或停机条件如果ProAct执行机构有任何报警或停机情况，请参阅第6章了解该情况的确切原因。LED将指示停机条件下的闪烁代码。必须使用观察窗或CAN来确定任何报警条件。离散输出如果离散输出不能正常工作，请验证以下内容： 测量接线板上的输出电压。当输出为关闭/错误时，810-072903-004它应该在（18到28）V（dc）的范围内。只有当所有警报和停机都为假时，电压才会在此范围内。这可以通过观察窗口进行验证。810-072903-004如果输出对地短路，输出保护电路将消除此电压。这需要一个电源循环（关闭/打开），以便在问题得到纠正后恢复输出。 检查接线，在接线板上寻找松动的连接以及断开或错误连接的电缆。 如果810-072903-004可用，则可以强制打开和关闭测试模式的输出，以验证功能。

Check the communication settings, should be set to 19200 baud, 8 data bits, 1 stop bit, and no parity. Service Tool If a serial port is not functioning properly, review the installation information in Chapter 8. Verify the following: ·810-072903-004 Check the wiring, look for a loose connection and disconnected or misconnected cables. Refer to the Serial (RS-232) Communications troubleshooting above. ·810-072903-004 Check that Servlink is running and communicating with the control.810-072903-004 Check that Watch Window is running. Verify the Servlink Error settings. If numbers don’t appear to be displayed correctly, verify the proper numeric format setting. Refer to Chapter 8 (Service Tool) for details.

The voltage will be in this range only if all alarms and shutdowns are false. This can be verified through Watch Window .810-072903-004 The output protection circuit will remove this voltage if the output was shorted to ground. This requires a power cycle (off/on) to restore the output once the problem is corrected. · Check the wiring, look for a loose connection at the terminal blocks and disconnected or misconnected cables. ·810-072903-004 If Watch Window Professional is available, the output can be forced on and off from the Test Mode to verify functionality. Serial (RS-232) Communications If a serial port is not functioning properly, verify the following: · Check the wiring, look for a loose connection and disconnected or misconnected cables. ·810-072903-004 

· Set “High Friction Load” = True, found on the Service Mode: Adjust User Stops tab sheet. · Increase the Actuator Inertia Setting and re-run the Inertia Test (Service Mode: Adjust User Stops tab sheet). ·810-072903-004 Free stuck linkage or load.Alarm or Shutdown Conditions If the ProAct actuator has any alarm or shutdown conditions, refer to Chapter 6 for details on the exact cause of the condition. The LED will indicate a flash code for shutdown conditions. Watch Window or CAN must be used to determine any alarm conditions. Discrete Output If the discrete output is not functioning properly, verify the following: ·810-072903-004 Measure the output voltage on the terminal block. 810-072903-004It should be in the range of (18 to 28) V (dc) when the output is off/false.
