SERVICE – Software Maintenance
DESCRIPTION: This screen allows the technician to perform
system software maintenance. NOTE: Use caution when
accessing this screen remotely with a web browser.
Perform the following steps to prepare the Quantum™ LX
for software maintenance:
• Ensure that all setpoint values have been
documented as a safety precaution. Install a
USB device into the provided connection on the
Quantum™.
• With power ON, insert the USB device into the
USB port. Ensure that the tabbed key of the drive
connector is plugged in as shown in Figure 1 of this
section.
• Go to User Level 2. The default password is 20.
• Press the [Menu] key.
• Cursor down to Service… and press [Enter].
• Cursor down to Software Maintenance and press
the [Enter] key.
The following selections have been provided:
1) Save Setpoints - Use this option to save all
setpoints and custom text to a USB device as a
form of backup:
• Press [1] to Save Setpoints.
• The program will read the USB device, and
the following dialog box will appear:
• Any numerals that appear on the center line
of this box will represent units that have
already been saved (from 0 to 99). If no units
have yet been saved, the center line will be
blank.
• Enter a number on the keypad that
corresponds to the unit number that you
wish to save, and then press [Enter]. If the
unit number has not been saved before, the
setpoints will be saved to a le on the USB
device (a progress bar will appear asking you
to Please Wait… In the future, any time you
try to write the setpoints to this number, you
will be prompted with a message telling you
that the set number already exists – do you
wish to overwrite it? Answer by highlighting
the Yes button, and pressing [Enter] if you
wish to overwrite the values. If you enter a
number that does not appear on the center
line, no such warning will appear.
• After the le has been written, the dialog
boxes will disappear, and you can either exit
or continue with another function.
2) Full System Install - Use this option to install the
program:
• Ensure that all setpoint values have been
documented as a safety precaution.
• Press [2] to do a Full System Install.
• If a valid USB device with the operating system
loaded on it is plugged in, the software will
be loaded. If however, there is no USB device
installed, or the device does not contain the
operating software, the following dialog box
will appear:
