Event logs. Certain ‘events’ are recorded to files on the micro-SD card.
These events include relay switching, SD card remove/insert, access to
program mode, and power up events. Once an event file reaches 1MB in
size, a new file will be created. The naming of the files and folders is like
those for Trend Logs except that the names are prefixed with E rather than L.
Trace logs. The naming of the files and folders is like those for Data Logs
except that the names are prefixed with T rather than L, and the file name
extension is .DAT, which allows the traces to be replayed in Ultra PC (within
PC suite software). If enabled in the Data Logs menu, a new folder for trace
logs will be created each day. Once a trace file reaches 1MB in size, a new
fie will be created.
Firmware files. The firmware in the Ultra 4 can be upgraded from a file
placed on the SD card. Firmware files have the extension. PU4 Contact
Pulsar for more information on Upgrading the Firmware.
Parameter files. A file of the current parameter settings can be saved to
the SD card and used as a backup, for archives, or to load into another Ultra
4 to “clone” the current parameter configuration.
The file name is prefixed with F, P or V depending on whether the unit is
configured as Flow (F) Pump (P) or Level/Volume (V). The rest of the file
name follows the same yymmddX format as described above. The file name
extension is .PR4. These files are also stored in the root folder.
When creating a parameter backup file, the filename is generated
automatically. When restoring parameters from a backup file the Ultra4
shows a list of available files to load.
Setting up the unit to log
Ensure that a micro-SD card has been inserted into the SD card slot ready to
begin logging. When the programming of the unit has been completed and
you return to run mode, the unit will begin to log data at the time interval
defined within the Data Logs menu.
You can view the micro-SD card logging information on Page 2 of the Info
screen in run mode. Page 3 of the Info screen will show you how much
memory you have left on the micro-SD card you are using.
Data gets written to the SD card in blocks every 15-minutes, or once the
amount of data to write reaches a pre-set limit.
