Capturing Data & Troubleshooting
Occasionally, it may be necessary to troubleshoot a difficult equipment problem. Use the Tracer TU
Data Logging Utility to capture data for review. A maximum of 25,000 samples can be stored on
the UC400. The factory configured data logs utilize approximately 15,000 samples.
To capture data:
1. Navigate to the Data Log Setup tab, and click Add New to configure a data log. Use the TU help
button for a detailed description of all parameters which can be defined on this page.
Note: Data Logs can also be configured by opening the point configuration for any point on
the UC400 and selecting the Data Log tab.
2. Check the enabled box in the Data Log group, then click Send to Device.
