COLOR SCHEME
Range: Green (open), Red (open)
Default: Green (open)
This setting defines the color scheme for the breaker status. If it is programmed Green
(open), the breaker open status is shown in the color green on the single line diagram
and on the device status.
FLASH MESSAGE TIME
Range: 1 to 10 s in steps of 1 s
Default: 5 s
Flash messages are status, warning, error, or information messages displayed for
several seconds in response to certain key presses during programming. These
messages override any normal messages. The duration of a flash message on the
display can be changed to accommodate different reading rates.
MESSAGE TIMEOUT
Range: 10 to 900 s in steps of 1 s
Default: 30 s
If no pushbutton has been pressed for a certain period of time, the relay automatically
reverts to its default message (screen). The inactivity time is modified via this setting to
ensure messages remain on the screen long enough during programming.
The target message interrupts the message timeout, overriding it. The message timeout
starts timing after each target message, and if no more activity is recorded for the
specified time, the display goes back to the default screen.
