Troubleshooting LQSE Din-Rail Modules

This article provides information to help diagnose most issues regarding LQSE Din-rail Modules, ranging from wiring issues to software/firmware issues. 
 
 
<h3>Wiring Verification</h3>
<hr></hr>
Before activating the LQSE to the system, confirm the modules are functioning and can control the loads directly from the module. This ensures the loads are wired and/or functioning correctly.
 
While each model varies on how this can be done, they will roughly follow the same steps:
<ol><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>Tap a zone/loop button</li><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>Use the up or down arrow to turn the load on/off or dim the load</li></ol>
 
For detailed instructions, please see the install guide for the specific module installed, at the Verify Lights section. See below for an example from the LQSE-4A5 and LQSE-2HDC installation guide:

<h3>Diagnostics Tab</h3>
<hr></hr>
Troubleshooting an LQSE Din-rail Module has never been easier when using the Lutron Designer software version 24+.
 
While the modules still have a variety of blink codes that display on them when an issue occurs, Designer now has a way of seeing what the blink code is and translating it for you without needing to walk over to the modules (in most cases). The Diagnostic Tab's Verify Devices screen will now display if there is an error code currently reporting from a Din-rail module within its status section. 
 
For more details on this, and a detailed explanation of the window, please see our <a href='https://support.lutron.com/us/en/product/homeworks/article/troubleshoot…; target='_blank'>Troubleshooting within Lutron Designer</a> knowledge article.
 
 
 
<h3>Blink Codes</h3>
<hr></hr>
If a blink code is present but is not being reported by the Diagnostics Tab, review the <a href='https://assets.lutron.com/a/documents/048803.pdf' target='_blank'>Adaptive Power Module Troubleshooting Guide App Note (048803) (lutron.com)</a> for an overview of each blink code, its causes, and recommended solutions. 
 
 
 
<h3>Device Not Activating</h3>
<hr></hr>
Follow the steps below to identify, and resolve, why the Din-rail module will not activate to your Homeworks system:
 
<ol><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>Verify the QS wiring
<ul><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>A common issue is having the 3 and 4 terminals (Mux and Muxbar cable) flipped on a single module or device on the link.</li></ul>
</li><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>Ensure there are no blink codes present on the device</li><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>Factory default the unit
<ul><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>This can be done using the Triple-Tap hold, Triple-tap method on the Prog button.</li></ul>
</li><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>If these do not work, we recommend using the Diagnostics tab's System Activity Viewer tool to verify if there is any Link Noise present.
<ul><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>For more details on this, please see our <a href='https://support.lutron.com/us/en/product/homeworks/article/troubleshoot…; target='_blank'>Troubleshooting within Lutron Designer Article</a></li><li style='font-size: 16px;font-family: helvetica, arial, sans-serif;'>Alternatively, you can also use the <a target='_blank'>Lutron Connect Portal</a> to see what the Link Noise reported is.</li></ul>
