Displaying/Setting the Calendar and Clock
The NT31/NT31C has a “clock function” for setting and displaying the date and
time.
This section describes how to display and set the clock data by menu operation
from the System Menu.
Reference
- The clock function does not strictly check the date and day of the week settings.
When setting the clock data, be sure to set the correct date and day of the week.
If a mistake is made — for example entering a value in the range 13 to 19 when
entering the month — the buzzer sounds three times.
Make sure that the data is correct when the month changes.
- Numeral memory tables 247 to 255 are reserved for the clock function. Clock
data can be displayed and set during operation of the NT31/NT31C by using
these numeral memory tables.
- For details on the clock function, refer to 7-15-6 “Clock Function” (page 456).
- No clock data is set on shipment from the factory.
- The clock data is backed up by the built-in battery of the NT31/NT31C. If the
battery voltage becomes low, the clock data cannot be retained when the power
to the NT31/NT31C is turned OFF or the NT31/NT31C is reset and the clock
function will not operate correctly.
- When writing to the screen data memory is disabled by the setting made for
“System Setting” in the System Installer mode, it is not possible to set the date
and time.
Display/set clock data by following the menu operation from the System Menu
shown below.
Select “Maintenance Mode”.
Select “Calendar Check”.
