Encountering an error message like "EVO_EVO_013_230: Te-Motion error" on your channel/cable assembly can be frustrating, especially when it prevents you from using the instrument. This error often appears to happen randomly, sometimes during initialization or in the middle of a script, particularly when the system is aspirating, dispensing, or picking up a Diti tip. While a simple restart might clear the error temporarily, it often returns and eventually becomes permanent.
A Te-Motion error indicates an issue with the movement or control of a specific channel's Z-rod motor. Think of it as a signal that something is mechanically wrong with the channel assembly itself. It's often not a software glitch but rather a hardware malfunction. This is why restarting the software or instrument may provide a brief reprieve but won't solve the underlying problem.
You'll likely see this error message in your software, but here are some of the actions that might trigger it:
Getting a Diti tip: The channel struggles to pick up a new disposable tip properly.
Aspirating liquid: The diluter's syringe or plunger isn't moving correctly to draw in the liquid.
Dispensing liquid: The system fails to push the liquid out smoothly.
Based on these symptoms, the most likely cause is an Air Liha malfunctioning channel/cable assembly. This assembly is a complex component essential for precise liquid handling. When it fails, the channel can no longer perform its movements reliably, leading to the Te-Motion error.
Since this is a hardware issue, it requires a physical replacement. Software resets and other troubleshooting steps won't work in the long term because they can't fix a broken mechanical part.
If you're experiencing a persistent "Te-Motion error" on a specific channel, the next step is to schedule a service to replace the Air Liha Channel assembly. This is the most effective way to resolve the issue and get your diluter back up and running.
