LAM 810-073479-005 控制器模塊
產(chǎn)品概述：
810-073479-005如果模擬輸出工作不正常，請驗證以下內(nèi)容：? 檢查負載電阻，確保其小于輸出電流的技術(shù)規(guī)格限制。? 檢查以確保負載接線已隔離。? 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。? 斷開現(xiàn)場接線，并在輸出端連接一個電阻器。如果電阻器兩端的輸出正確，則現(xiàn)場接線有問題。? 如果810-073479-005可用，則可以從測試模式強制輸出電流以驗證功能。此外，810-073479-005“服務(wù)模式”中還提供“偏移”和“增益”調(diào)整。離散輸入-如果離散輸入不能正常工作，請驗證以下內(nèi)容：810-073479-005? 測量接線板上的輸入電壓。它應(yīng)該在（18到28）V（dc）的范圍內(nèi)。? 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。
電氣故障排除指南模擬輸入如果模擬輸入工作不正常，請驗證以下內(nèi)容：? 測量接線板上的輸入電壓。它應(yīng)該在（0到5）V的范圍內(nèi)。? 驗證模擬輸入信號是否沒有交流分量或交流分量最小。810-073479-005交流部件可能由屏蔽不當引起。? 檢查接線。如果輸入讀數(shù)為0或?qū)?yīng)于0 mA的工程單位，則在接線板上尋找松動的連接以及斷開或錯誤連接的電纜。檢查接線板上的跳線安裝是否正確（JPR1適用于200 mA范圍，JPR2適用于20 mA范圍）。810-073479-005? 檢查接線板上的跳線安裝是否正確（JPR1適用于200 mA范圍，JPR2適用于20 mA范圍）。810-073479-005? 如果所有輸入的讀數(shù)都為高，請檢查電源是否直接連接到輸入兩端。? 810-073479-005檢查軟件配置，以確保將輸入正確配置為主要需求或備份需求。驗證模擬輸入最小值和最大值配置。? 在位置控制、模擬需求的維修模式下，使用維修工具檢查ProAct執(zhí)行器看到的值。如果輸入出現(xiàn)故障，如閃爍代碼51所示，且毫安輸入在正常范圍內(nèi)，請檢查“模擬輸入故障最小值”和“模擬輸出故障最大值”的服務(wù)模式設(shè)置。
Check the wiring, look for a loose connection at the terminal blocks and disconnected or misconnected cables. · Disconnect the field wiring and connect a resistor across the output. If the output is correct across the resistor, there is a problem with the field wiring. ·810-073479-005 If Watch Window Professional is available, the output current can be forced from the Test Mode to verify functionality. In addition, Offset and Gain adjustment are available in the Service Mode. Discrete Inputs If a discrete input is not functioning properly, verify the following: · Measure the input voltage on the terminal block.810-073479-005 It should be in the range of (18 to 28) V (dc). ·810-073479-005 Check the wiring, look for a loose connection at the terminal blocks and disconnected or misconnected cables.
If all of the inputs are reading high, check that the power is not connected across the input directly. · Check the software configuration to ensure that the input is configured properly as either a primary or backup demand. Verify the Analog In Min and Max Value configurations. ·810-073479-005 Check the values seen by the ProAct actuator using the Service Tool in the Service mode under Position Control, Analog Demand. If the input is failed, as indicated by flash code 51, and the milliamp input is in the normal range, check the Service mode settings for Analog In Fail Min and Fail Max.810-073479-005 Analog Output If the Analog output is not functioning properly, verify the following: ·810-073479-005 Check the load resistance, ensure that it is less than the specification limit for the output current. ·810-073479-005 Check to ensure that the load wiring is isolated.
Electrical Troubleshooting Guide Analog Input If the Analog input is not functioning properly, verify the following: ·810-073479-005 Measure the input voltage on the terminal block. It should be in the range of (0 to 5) V. · Verify that there are no or minimal ac components to the Analog Input signal. AC components can be caused by improper shielding. ·810-073479-005 Check the wiring. If the inputs are reading 0 or the engineering units that correspond to 0 mA, look for a loose connection at the terminal blocks and disconnected or misconnected cables. Check for proper jumper installation on the terminal block (JPR1 for 200 mA range and JPR2 for 20 mA range). ·810-073479-005 Check for proper jumper installation on the terminal block (JPR1 for 200 mA range and JPR2 for 20 mA range).
