FLASH MESSAGE TIME
Range: 1 s to 65535 s
Default: 5 s
Flash messages are status, warning, error, or information messages displayed for
several seconds in response to certain key presses during setting 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: 1 s to 65535 s
Default: 30 s
If the keypad is inactive for a period of time, the relay automatically reverts to a default
message. The inactivity time is modified via this setting to ensure messages remain on
the screen long enough during programming or reading of actual values.
SCREEN SAVER
Range: Off, 1 min to 10000 min
Default: Off
The life of the LCD backlight can be prolonged by enabling the Screen Saver mode.
If the keypad is inactive for the selected period of time, the relay automatically shuts off
the LCD screen. Any activity (keypress, alarm, trip, or target message) will restore screen
messages.
