LAM 810-072903-004 半導體
產(chǎn)品概述：
810-072903-004串行（RS-232）通信如果串行端口工作不正常，請驗證以下內(nèi)容：? 檢查接線，尋找松動的連接和斷開或錯誤連接的電纜。? 檢查通信設(shè)置，810-072903-004應設(shè)置為19200波特、8個數(shù)據(jù)位、1個停止位和無奇偶校驗。維修工具如果串行端口工作不正常，請查看第8章中的安裝信息。驗證以下內(nèi)容：? 檢查接線，尋找松動的連接和斷開或錯誤連接的電纜。請參閱上述串行（810-072903-004）通信故障排除。? 檢查Servlink是否正在運行并與控件通信。檢查“監(jiān)視窗口”是否正在運行。驗證Servlink錯誤設(shè)置。如果數(shù)字顯示不正確，請驗證數(shù)字格式設(shè)置是否正確。810-072903-004有關(guān)詳細信息，請參閱第8章（維修工具）。
810-072903-004報警或停機條件如果ProAct執(zhí)行機構(gòu)有任何報警或停機情況，請參閱第6章了解該情況的確切原因。LED將指示停機條件下的閃爍代碼。必須使用觀察窗或CAN來確定任何報警條件。離散輸出如果離散輸出不能正常工作，請驗證以下內(nèi)容：? 測量接線板上的輸出電壓。當輸出為關(guān)閉/錯誤時，810-072903-004它應該在（18到28）V（dc）的范圍內(nèi)。只有當所有警報和停機都為假時，電壓才會在此范圍內(nèi)。這可以通過觀察窗口進行驗證。810-072903-004如果輸出對地短路，輸出保護電路將消除此電壓。這需要一個電源循環(huán)（關(guān)閉/打開），以便在問題得到糾正后恢復輸出。? 檢查接線，在接線板上尋找松動的連接以及斷開或錯誤連接的電纜。? 如果810-072903-004可用，則可以強制打開和關(guān)閉測試模式的輸出，以驗證功能。
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.
