The optional user-programmable pushbuttons (specified in the order code) provide an easy and error-free method of enter-
ing digital state (on, off) information. The number of available pushbuttons is dependent on the faceplate module ordered
with the relay.
• Type P faceplate: standard horizontal faceplate with 12 user-programmable pushbuttons.
• Type Q faceplate: enhanced horizontal faceplate with 16 user-programmable pushbuttons.
The digital state can be entered locally (by directly pressing the front panel pushbutton) or remotely (via FlexLogic™ oper-
ands) into FlexLogic™ equations, protection elements, and control elements. Typical applications include breaker control,
autorecloser blocking, and setting groups changes. The user-programmable pushbuttons are under the control level of
password protection.
The user-configurable pushbuttons for the enhanced faceplate are shown below.

Both the standard and enhanced faceplate pushbuttons can be custom labeled with a factory-provided template, available
online at http://www.GEmultilin.com. The EnerVista UR Setup 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
1 OFF
active, the operand will be asserted.
ANY PB ON
Each pushbutton has an associated LED indicator. By default, this indicator displays the present status of the correspond-
ing pushbutton (on or off). However, each LED indicator can be assigned to any FlexLogic™ operand through the
setting.

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 state
BTN 1 SET
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
ting or by directly pressing the associated active front panel pushbutton.
