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 time 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 will also return to this first screen (i.e. default screen 1).
Path:
Setpoints > Device > Front Panel > Default Screen
FUNCTION
Range: Disabled, Enabled
Default: Enabled
This setpoint enables the feature. Displaying of the screen starts 30 s after setting the
feature to "Enabled", providing no targets have been issued, nor a PB has been pressed.
DISPLAY TIME
Range: 5 to 900 s in step of 1 s
Default: 10 s
The display time is the amount of time that each of the three screens are displayed
within the display sequence.
DEFAULT SCREEN 1(3)
Range: varieties of screens for selection
Default: SLD (for Default Screen 1 only), Off (for Default Screen 2/3 only)
The setpoint enables the user to input up to 3 default screens from a list of screens.
Some events can be programmed to latch the faceplate LED event indicators and target
message on the display. Depending on the application some auxiliary output relays can be
programmed to latch after the triggering event is cleared. Once set, the latching
mechanism holds all the latched indicators, messages, and auxiliary output relays in the
set state, after the initiating condition has cleared, until a RESET command is received to
return these latches (except the FlexLogic latches) to the reset state.
The RESET command can be sent from the faceplate Reset pushbutton, a remote device
via a communication channel, or any programmed FlexLogic operand. Executing the
RESET command from either source creates a general FlexLogic operand RESET OP. Each
individual source of a RESET command also creates its individual operand RESET OP (PB),
RESET (COMMS), and RESET OP (OPERAND) to identify the source of the command.
RESET INPUT 1(2,3):
Range: Off, Any operand from the list of FlexLogic operands
Default: Off
The setpoint selects an operand from the list of FlexLogic operands. The targets, LEDs,
and latched output relays reset upon assertion from any of the operands selected as
Reset Inputs.
