• PUSHBTN 1 SET : This setting assigns the FlexLogic™ operand serving to operate the pushbutton element and to
assert
PUSHBUTTON 1 ON
operand. The duration of the incoming set signal must be at least 100 ms.
• PUSHBTN 1 RESET : This setting assigns the FlexLogic™ operand serving to reset pushbutton element and to assert
PUSHBUTTON 1 OFF
operand. This setting is applicable only if pushbutton is in latched mode. The duration of the
incoming reset signal must be at least 50 ms.
• PUSHBTN 1 AUTORST : This setting enables the user-programmable pushbutton autoreset feature. This setting is
applicable only if the pushbutton is in the “Latched” mode.
• PUSHBTN 1 AUTORST DELAY : This setting specifies the time delay for automatic reset of the pushbutton when in
the latched mode.
• PUSHBTN 1 REMOTE : This setting assigns the FlexLogic™ operand serving to inhibit pushbutton operation from the
operand assigned to the
PUSHBTN 1 SET
or
PUSHBTN 1 RESET
settings.
• PUSHBTN 1 LOCAL : This setting assigns the FlexLogic™ operand serving to inhibit pushbutton operation from the
front panel pushbuttons. This locking functionality is not applicable to pushbutton autoreset.
• PUSHBTN 1 DROP-OUT TIME : This setting applies only to “Self-Reset” mode and specifies the duration of the push-
button active status after the pushbutton has been released. When activated remotely, this setting specifies the entire
activation time of the pushbutton status; the length of time the operand remains on has no effect on the pulse duration.
This setting is required to set the duration of the pushbutton operating pulse.
• PUSHBTN 1 LED CTL : This setting assigns the FlexLogic™ operand serving to drive pushbutton LED. If this setting is
“Off”, then LED operation is directly linked to
PUSHBUTTON 1 ON
operand.
• PUSHBTN 1 MESSAGE : If pushbutton message is set to “High Priority”, the message programmed in the
PUSHBTN 1
ID
and
PUSHBTN 1 ON TEXT
settings will be displayed undisturbed as long as
PUSHBUTTON 1 ON
operand is asserted.
The high priority option is not applicable to the
PUSHBTN 1 OFF TEXT
setting.
This message can be temporary removed if any front panel keypad button is pressed. However, ten seconds of keypad
inactivity will restore the message if the
PUSHBUTTON 1 ON
operand is still active.
If the
PUSHBTN 1 MESSAGE
is set to “Normal”, the message programmed in the
PUSHBTN 1 ID
and
PUSHBTN 1 ON TEXT
settings will be displayed as long as
PUSHBUTTON 1 ON
operand is asserted, but not longer than time period specified
by
FLASH MESSAGE TIME
setting. After the flash time is expired, the default message or other active target message is
displayed. The instantaneous reset of the flash message will be executed if any relay front panel button is pressed or
any new target or message becomes active.
The
PUSHBTN 1 OFF TEXT
setting is linked to
PUSHBUTTON 1 OFF
operand and will be displayed in conjunction with
PUSHBTN 1 ID
only if pushbutton element is in the “Latched” mode. The
PUSHBTN 1 OFF TEXT
message will be displayed
as “Normal” if the
PUSHBTN 1 MESSAGE
setting is “High Priority” or “Normal”.
• PUSHBUTTON 1 EVENTS : If this setting is enabled, each pushbutton state change will be logged as an event into
event recorder.
