The Menus in Detail
"Uhr"
This menu when selected displays the time of the slave line. After power on this menu
is shown as default.
"Uhr SET"
This menu lets the user set the internal slave clock time to the time shown on the
connected slave clocks.
When pressing SET the first time the slave line time appears on the display with the
first digit of the hours blinking. Pressing SET once more causes the slave line time to
stop. Keeping the SET key pressed for a longer time the blinking digit is incremented.
Pressing SET briefly causes the next digit to blink. Leaving this menu lets the
NUC80E start the slave line.
"Minuten"
This menu is given for testing the minute slave line. Minutes and hours are displayed.
Pressing SET lets the user switch on or off the slave line. This state is indicated with a
"H" (hold) or a "R" (run) shown in the display.
"Hauptuhr"
This menu displays the time received from the preconnected radio clock.
Alarm Menus
"UHRALARM" (blinking) indicates an invalid slave clock time. This alarm is
possible only after power up (when the buffered RAM is cleared because of empty or
defect buffer capacitor).
"MIN-FEHL" or "SEK_FEHL" (blinking) indicates a short circuit at the corre-
sponding slave line.
"SER_FEHL" (blinking) indicates a missing or faulty serial string.
Each of this cases causes a relay to become active 90 seconds after the alarm has been
established.
