CHAPTER 5: SETTINGS
The pulse duration of the remote set or local front panel pushbutton must be at least 50 ms to operate the
pushbutton. This allows the user-programmable pushbuttons to properly operate during power cycling events and
various system disturbances that can cause transient assertion of the operating signals.
The local and remote operation of each user-programmable pushbutton can be inhibited through the
and settings. If local inhibit is applied, the pushbutton ignores set and reset commands executed
PUSHBTN 1 REMOTE
through the front panel pushbuttons. If remote inhibit is applied, the pushbutton ignores set and reset commands
executed through FlexLogic operands.
The inhibit functions are not applied to the autoreset feature. The inhibit function can be used in SBO control operations to
prevent user-programmable pushbutton activation and ensuring "one-at-a-time" select operation.
The inhibit functions can also be used to prevent pushbutton activation from the accidental pressing of the front panel
pushbuttons. The separate inhibit of the local and remote operation simplifies the implementation of local/remote control
supervision.
Pushbutton states can be logged by the event recorder. User-defined messages can also be associated with each
pushbutton and displayed when the pushbutton is activated and when in latched mode when the pushbutton deactivated.
— This setting selects the mode of the pushbutton (Self-Reset, Latched, Disabled). If set to
PUSHBUTTON 1 FUNCTION
"Disabled," the pushbutton is not active and the corresponding FlexLogic operands (both "On" and "Off") are de-asserted.
— This setting specifies the top 20-character line of the user-programmable pushbutton message and is
PUSHBTN 1 ID TEXT
intended to provide ID information of the pushbutton. See the User-definable Displays section in this chapter for
instructions on how to enter alphanumeric characters from the keypad.
— This setting specifies the bottom 20-character line of the user-programmable pushbutton message
PUSHBTN 1 ON TEXT
and is displayed when the pushbutton is in the "on" position. See the User-definable Displays section for instructions on
entering alphanumeric characters from the keypad.
— This setting specifies the bottom 20-character line of the user-programmable pushbutton message
PUSHBTN 1 OFF TEXT
and displays when the pushbutton is deactivated and the
display when the

release. The length of the "Off" message is configured with the
setting.
TIME
— This setting specifies the time required for a front panel pushbutton to be pressed before it is deemed
PUSHBTN 1 HOLD
active. This timer is reset upon release of the pushbutton. Note that user-programmable pushbutton operation requires the
front panel pushbutton to be pressed a minimum of 50 ms. This minimum time is required prior to activating the user-
programmable pushbutton hold timer.
— This setting assigns the FlexLogic operand serving to activate the user-programmable pushbutton

element. The duration of the incoming set signal must be at least 50 ms.
— This setting assigns the FlexLogic operand serving to deactivate the user-programmable pushbutton
PUSHBTN 1 RESET
element. This setting is applicable only if the user-programmable pushbutton is in "Latched" mode.
— This setting enables the user-programmable pushbutton autoreset feature. This setting is applicable
PUSHBTN 1 AUTORST
only if the pushbutton is in "Latched" mode.
— This setting specifies the time delay for automatic reset of the pushbutton when in "Latched"

mode.

programmable pushbutton active status after the front panel pushbutton has been released. When activated remotely,
this setting specifies the entire activation time of the pushbutton; the length of time the operand selected by
