After startup, the user may navigate to the Title Screen from the Main Menu Screen. This
allows the user to adjust the LCD contrast at any time during the operation of the SC-2124.
The Title Screen is displayed for five seconds before navigating back to the Main Menu
Screen. The user may immediately navigate back to the Main Menu Screen by pressing the
ESC Key at any time.
5.2.2 Main Menu Screen
The Main Menu Screen allows fast navigation to all other Run Screens. To navigate to a
particular Run Screen, the user must press the
Soft Key
located directly under the
corresponding Screen Name listed on the Main Menu Screen: SCAN, Custom, Channel, or
SNAP. The user may also navigate to the Title Screen by pressing the ESC Key.
5.2.3 Main SCANNER Screen
One of the SC-2124 Run Screens is user-configured as the Main SCANNER Screen. This is
the main screen where the user views and monitors most of the information displayed by the
SCANNER. By default, the SCAN Screen is configured as the SCANNER Screen, but the
user may also configure the Custom Screen(s) as the SCANNER Screen.
For either configuration, the SCANNER Screen displays current measurement readings of
the analog input channels during normal operation. When a
SHUTDOWN
occurs, the
SCANNER automatically navigates
†
back to the Main SCANNER Screen to display the First-
Out
SHUTDOWN
channel, i.e. the cause of the
SHUTDOWN
(See Section 4.4). No
navigation may be performed until the First-Out
SHUTDOWN
is acknowledged by a
SCANNER RESET (See Section 4.1).
Since the Main SCANNER Screen is the default screen of primary interest to the user, the
SCANNER automatically navigates
†
back to the Main SCANNER Screen after 60 seconds of
user inactivity (delay is user-configurable).
†
Note: The SCANNER performs the automatic navigation
only
if the SC-2124
is in RUN Mode Screens,
not
in CONFIGURATION Mode. This allows the
user to enter CONFIGURATION Mode during a
SHUTDOWN
to modify
parameters that may cancel the
SHUTDOWN
condition.
