Both the standard and enhanced faceplate pushbuttons can be custom labeled with a factory-provided template,
available online at http://www.gedigitalenergy.com/multilin. The EnerVista software can also be used to create labels for
the enhanced faceplate.
Each pushbutton asserts its own "On" and "Off" FlexLogic operands (for example,
These operands are available for each pushbutton and are used to program specific actions. If any pushbutton is active,
the operand is asserted.
ANY PB ON
Each pushbutton has an associated LED indicator. By default, this indicator displays the present status of the
corresponding pushbutton (on or off). However, each LED indicator can be assigned to any FlexLogic operand through the
setting.

The pushbuttons can be automatically controlled by activating the operands assigned to the

the operand is asserted. The activation and deactivation of user-programmable pushbuttons is dependent

on whether latched or self-reset mode is programmed.
• Latched mode — In latched mode, a pushbutton can be set (activated) by asserting the operand assigned to the
setting or by directly pressing the associated front panel pushbutton. The pushbutton maintains the set
PUSHBTN 1 SET
state until deactivated by the reset command or after a user-specified time delay. The state of each pushbutton is
stored in non-volatile memory and maintained through a loss of control power.
The pushbutton is reset (deactivated) in latched mode by asserting the operand assigned to the
setting or by directly pressing the associated active front panel pushbutton.
It can also be programmed to reset automatically through the
settings. These settings enable the autoreset timer and specify the associated time delay. The autoreset timer can be
used in select-before-operate (SBO) breaker control applications, where the command type (close/open) or breaker
location (feeder number) must be selected prior to command execution. The selection must reset automatically if
control is not executed within a specified time period.
• Self-reset mode — In self-reset mode, a pushbutton remains active for the time it is pressed (the pulse duration) plus
the dropout time specified in the
pulse duration is specified by the
setting has no effect on the pulse duration.
PUSHBTN 1 SET
The pushbutton is reset (deactivated) in self-reset mode when the dropout delay specified in the
setting expires.
TIME
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.
