LAM 810-073479-005 控制器模块

产品概述：

810-073479-005如果模拟输出工作不正常，请验证以下内容： 检查负载电阻，确保其小于输出电流的技术规格限制。 检查以确保负载接线已隔离。 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。 断开现场接线，并在输出端连接一个电阻器。如果电阻器两端的输出正确，则现场接线有问题。 如果810-073479-005可用，则可以从测试模式强制输出电流以验证功能。此外，810-073479-005“服务模式”中还提供“偏移”和“增益”调整。离散输入-如果离散输入不能正常工作，请验证以下内容：810-073479-005 测量接线板上的输入电压。它应该在（18到28）V（dc）的范围内。 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。

电气故障排除指南模拟输入如果模拟输入工作不正常，请验证以下内容： 测量接线板上的输入电压。它应该在（0到5）V的范围内。 验证模拟输入信号是否没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当引起。 检查接线。如果输入读数为0或对应于0 mA的工程单位，则在接线板上寻找松动的连接以及断开或错误连接的电缆。检查接线板上的跳线安装是否正确（JPR1适用于200 mA范围，JPR2适用于20 mA范围）。810-073479-005 检查接线板上的跳线安装是否正确（JPR1适用于200 mA范围，JPR2适用于20 mA范围）。810-073479-005 如果所有输入的读数都为高，请检查电源是否直接连接到输入两端。 810-073479-005检查软件配置，以确保将输入正确配置为主要需求或备份需求。验证模拟输入最小值和最大值配置。 在位置控制、模拟需求的维修模式下，使用维修工具检查ProAct执行器看到的值。如果输入出现故障，如闪烁代码51所示，且毫安输入在正常范围内，请检查“模拟输入故障最小值”和“模拟输出故障最大值”的服务模式设置。

 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).
