Fix EVO_EVO_013_004 on Tecan EVO: Real or False Collision

Seeing the EVO_EVO_013_004 error code flash on your Tecan Freedom EVO system—especially when there’s no actual physical collision—can be frustrating and confusing. Don’t panic—you’re not alone! Discover the steps to resolve both real and false collision issues.

What Is the EVO_EVO_013_004 Error?

The EVO_EVO_013_004 error is a collision detection alert from the Tecan Freedom EVO system, specifically triggered on the Z-axis of the LiHa (Liquid Handling Arm). It can occur during system startup or when initiating liquid handling commands like Get DITIs (Disposable Tips). This error can disrupt the instrument’s startup process, preventing it from completing initialization or receiving further commands. While this error can result from a real physical collision, it can also be caused by a false positive.

Step-by-Step Troubleshooting Guide

Step 1. Restart the System

• Turn off the Tecan Freedom EVO system to begin troubleshooting the EVO_EVO_013_004 error.
• Reboot the instrument computer and log in to Windows.
• Turn on the Tecan Freedom EVO.
• Launch the Freedom EVOware Software and start a script/process run to monitor for any error messages.

Step 2. Verify Labware Parameters

• Right-click on the DITI carrier and select Edit Labware Type in EVOware software to adjust settings for troubleshooting the EVO_EVO_013_004 error.
  

• In the Edit Labware Type window, select LiHa (DiTi Cones Only) as the Device to be used for teaching (Step A).

• Verify that the channels can move to the correct position by clicking move to well #1 (Step B), and then Z-Start (Step C).

• If the channels reach the DITI carrier as shown below, test Tips 1 to 8 (Step E) to see if EVOware Software generates any error codes.

• Once all eight channels move correctly, adjust the Z-Max value to no more than 1540 (Step D). Click "OK" to save the change.

• Start the script to verify if the error reoccurs.

By following these steps, you can quickly identify and resolve the EVO_EVO_013_004 error on your TECAN EVO system. Ensuring proper labware setup and verifying LiHa arm movement are key to preventing future interruptions.
