Data Logging Retrieval
Onboard data logging records and stores data listed in Table 35 which can be loaded onto a portable USB storage device in a
comma separated value (CSV) file. The sampling period is determined by the Sampling Period shown in Figure 77 and listed
in Table 34. This information can be used for troubleshooting or energy modeling purposes. Data logging can be
enabled/disabled via the Technician menu shown in Figure 77. To retrieve data logging information:
1.
Insert a portable USB storage device into the USB bulkhead located inside the HMI enclosure.
2.
Navigate to Settings menu, Technician Page 1 of 2 shown in Figure 77. Press "Download Log". A loading bar will
appear and display the current progress of the file downloads until complete.
