CHAPTER 5: SETTINGS
The pulse duration of the remote set, remote reset, or local 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, respectively. If local locking is applied, the pushbutton ignores set and reset commands
PUSHBTN 1 REMOTE
executed through the front panel pushbuttons. If remote locking is applied, the pushbutton ignores set and reset
commands executed through FlexLogic operands.
The locking functions are not applied to the autoreset feature. In this case, the inhibit function can be used in SBO control
operations to prevent the pushbutton function from being activated and ensuring "one-at-a-time" select operation.
The locking functions can also be used to prevent 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 and displayed as target messages. In latched mode, user-defined
messages can also be associated with each pushbutton and displayed when the pushbutton is on or changing to off.
— This setting selects the characteristic of the pushbutton. If set to "Disabled," the pushbutton is

not active and the corresponding FlexLogic operands (both "On" and "Off") are de-asserted. If set to "Self-Reset," the
control logic is activated by the pulse (longer than 100 ms) issued when the pushbutton is being physically pressed or
virtually pressed via a FlexLogic operand assigned to the
When in "Self-Reset" mode and activated locally, the pushbutton control logic asserts the "On" corresponding FlexLogic
operand as long as the pushbutton is being physically pressed, and after being released the deactivation of the operand is
delayed by the drop out timer. The "Off" operand is asserted when the pushbutton element is deactivated. If the
pushbutton is activated remotely, the control logic of the pushbutton asserts the corresponding "On" FlexLogic operand
only for the time period specified by the
If set to "Latched," the control logic alternates the state of the corresponding FlexLogic operand between "On" and "Off" on
each button press or by virtually activating the pushbutton (assigning set and reset operands). When in the "Latched"
mode, the states of the FlexLogic operands are stored in a non-volatile memory. If power supply is lost, the correct state of
the pushbutton is retained upon subsequent power up of the relay.

— This setting specifies the time required for a pushbutton to be pressed before it is deemed active. This

timer is reset upon release of the pushbutton. Note that any pushbutton operation requires the pushbutton to be pressed a
minimum of 50 ms. This minimum time is required prior to activating the pushbutton hold timer.
— This setting assigns the FlexLogic operand serving to operate the pushbutton element and to assert

operand. The duration of the incoming set signal must be at least 100 ms.

— This setting assigns the FlexLogic operand serving to reset pushbutton element and to assert

signal must be at least 50 ms.
