Access Codes
There are three levels of access code protection. If the
Master
password is used in the
WebMasterONE, then any set point can be changed. If the
Calibration Level
password is used,
then sensor calibrations will be allowed, but other changes will not. If the
Read Only
password is
used the user will be able to look at any menu, but will not be allowed to make any changes.
In order to change the access code for each level of access, use the Next key to move the cursor to
the space next to Present, and use the Arrow keys to make the characters match the present access
code (you have to know the present code to change it). Press the Enter key to move the cursor next
to New, then use the Arrow keys to make the characters match your new access code and press
Enter.
The default user name is "webmaster" and the default passwords are "2001" for full access, "2002"
for calibration only, and "2003" for read only. These defaults can and should be changed to assure
security.
5.10 Software
Upgrade
CAUTION!
There are live circuits inside the controller even when the power switch on the front
panel is in the OFF position! The front panel must never be opened before power to the controller
is REMOVED!
The software of the controller may be easily updated in the field, adding new features or fixing any
bugs. This can be accomplished in a few quick steps:
a.
Save the new software upgrade to a 32 MB (or higher) USB flash memory stick.
These are available from the factory, or may be found locally.
b.
Plug the memory stick into one of the USB Host connections on the core interface
board (see Figure 3). The stick will only fit in one direction.
c.
Enter the Software Upgrade Menu. Press Next until the word START is
highlighted, then press Enter.
d.
The Status section of the screen will indicate that the upgrade has started. Once it
finishes (in a few minutes) the controller will reboot.
e.
Remove the memory stick. This may be used to upgrade as many controllers as
you would like.
5.11 Copy to USB Disk
CAUTION!
There are live circuits inside the controller even when the power switch on the front
panel is in the OFF position! The front panel must never be opened before power to the controller
is REMOVED!
The data log file may be manually downloaded to a USB disk. Press Enter to initiate the process:
1.
Plug a USB memory stick into one of the USB host connections. The file size may
be as large as 2 MB.
2.
Press Enter when ‘Copy User Log’ is highlighted to start downloading.
3.
When the Copy Status becomes ‘File Copied’, you may press Exit to return to the
Main Menu and remove the USB disk.
