5.2 PRODUCT SETUP
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.gedigitalenergy.com/multilin. 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

Each pushbutton has an associated LED indicator. By default, this indicator displays the present status of the correspond-

• Latched mode: In latched mode, a pushbutton can be set (activated) by asserting the operand assigned to the
