Calling the System Installer Mode
If the NT31/NT31C has no system program installed, or if the system program is
destroyed, the System Installer mode is automatically established when the power
is switched ON.
To establish the System Installer mode in order to install a system program or
make settings for data management, either turn the power ON, or reset the
NT31/NT31C, while pressing the touch switch at the top left corner of the touch
panel (size: 7.2 mm 7.2 mm).
POWER
RUN
Switch the power to the NT31/NT31C ON while pressing this touch switch.
Selecting Menu Items
The menu items in the System Menu are displayed on the NT31/NT31C screen as
touch switches. Menu items can be selected simply by pressing them.
Example: Displaying the MAINTENANCE MODE MENU screen by pressing
“Maintenance Mode” in the System Menu.
Press “Maintenance Mode”.
Switching from the System Menu to the RUN Mode
Return to the RUN mode by selecting “Quit” in the System Menu and other menus.
Reference: Unlike previous PT models, the NT31/NT31C does not return to the RUN mode
automatically if no operations are performed.
