CHAPTER 5: SETTINGS
The B90 is provided with this optional feature, specified as an option at the time of ordering. Using the order
code for your device, see the order codes in chapter 2 for details.
User-programmable pushbuttons provide an easy and error-free method of entering 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
operands) 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 figure shows user-configurable pushbuttons for the enhanced faceplate.

The following figure shows user-configurable pushbuttons for the standard faceplate.

Both the standard and enhanced faceplate pushbuttons can be custom labeled with a factory-provided template,
available online at http://www.gegridsolutions.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.
