2.3 Data Log Files
The data log files listed in this section are available on
MPACt 1500 controllers with version 2.0.0 or later
application code. The data log files can be viewed using
spreadsheet software and used to help troubleshoot
ATS operation problems.
Data log files are generated by the MPAC 1500
controller as described below. See TP-6714, MPACt
1500 Operation Manual, for detailed instructions to
create the following data files.
USB Data Logger
Use the USB Data Logger function in the MPAC 1500
controller’s Set System menu to create a DataLog file.
The file contains time- and date-stamped readings of
voltage, frequency, and contactor position (source 1 or
2). Data log files have the form
DataLogYYMMDDHHMMSS.csv where YYMMDD is
the date (year/month/day), and HHMMSS is the time
that the file was created in hours:minute:seconds.
Figure 2-3 shows a sample file.
Figure 2-3 Sample Data Log File
MinMax Files
Use the MinMax function, which is found in the MPAC
1500 controller’s Set System menu under USB Data
Logger, to create a MinMax.csv file. The file contains
minimum and maximum readings of voltage and current
supplied to the load over a selected time period. The
MinMax file is overwritten each time the MinMax
operation is performed.
