Default Screens - GE 845 Instruction Manual

DEVICE

Default Screens

4–66
SCREEN SAVER
Range: Off, On
Default: Off
When the screen saver is set to ON, the LCD backlighting is turned off after the Message
Timeout followed by a time of 5 min, providing that no PB has been pressed and no
target messages are active. When a PB press occurs, or a target becomes active, the
LCD backlighting is turned on.
TARGET AUTO NAVIGATION
Range: Disabled, Enabled
Default: Disabled
When the target auto navigation is set to Enabled, it will override the current menu page
and go to the target message page when a target is active.
The Active target Icon shown above, will be the only indication of active target
messages.
LANGUAGE
Range: English, Polish
Default: English
This setting selects the language used to display the settings, metering, status, and
targets. The range is dependent on the order code of the relay.
The 8 Series relay provides the convenience of configuring and displaying up to three
default screens from a predefined list. The user selects each type of screen to display, and
programs the display time. The sequence of displaying the screens starts after the time of
inactivity programmed in the Message Timeout setpoint, no PB has been pressed, no
target message is present. Pressing a pushbutton, or the presence of a target message
inhibits the sequential display of default screens. The screen displays resume only after
the target messages are cleared, and no PB pressing is recorded for 30 seconds. When
configured the home screen is changed to the first screen defined by this feature. Display
timeouts also return to this first screen (i.e. default screen 1).
If the default screens feature is disabled and there are no home screens programmed, the
home page will show the Metering\ Summary\ Values screen after the message timeout
inactivity period.
