DISPLAY PROPERTIES
Some relay messaging characteristics can be modified to suit different situations using the display properties settings.
• LANGUAGE : This setting selects the language used to display settings, actual values, and targets. The range is
dependent on the order code of the relay.
• FLASH MESSAGE TIME : 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 mes-
sages. The duration of a flash message on the display can be changed to accommodate different reading rates.
• DEFAULT MESSAGE TIMEOUT : 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.
• DEFAULT MESSAGE INTENSITY : To extend phosphor life in the vacuum fluorescent display, the brightness can be
attenuated during default message display. During keypad interrogation, the display always operates at full brightness.
• SCREEN SAVER FEATURE and SCREEN SAVER WAIT TIME : These settings are only visible if the F35 has a liquid
crystal display (LCD) and control its backlighting. When the
SCREEN SAVER FEATURE
is “Enabled”, the LCD backlighting
is turned off after the
DEFAULT MESSAGE TIMEOUT
followed by the
SCREEN SAVER WAIT TIME
, providing that no keys
have been pressed and no target messages are active. When a keypress occurs or a target becomes active, the LCD
backlighting is turned on.
