Front-Panel Pushbutton Operation
Front-Panel Pushbutton Operation
Overview
Note in Figure 11.1 that most of the pushbuttons have dual functions
(primary/secondary).
A primary function is selected first (e.g., {METER} pushbutton).
After a primary function is selected, the pushbuttons revert to operating on
their secondary functions ({CANCEL}, {SELECT}, left/right arrows, up/down
arrows, {EXIT}). For example, after the {METER} pushbutton is pressed, the up/
down arrows are used to scroll through the front-panel metering screens. The
primary functions are activated again when the present selected function
(metering) is exited (press {EXIT} pushbutton) or the display goes back to the
default display after no front-panel activity for a settable time period (see
global setting FP_TO in Global Settings (Serial Port Command SET G and
Front Panel) on page SET.22; the relay is shipped with FP_TO = 15 minutes).

Primary Functions
Note in Figure 11.2 and Figure 11.3 that the front-panel pushbutton primary
functions correspond to serial port commands—both retrieve the same
information or perform the same function. To get more detail on the
information provided by the front-panel pushbutton primary functions, refer to
the corresponding serial port commands in Table 10.5. For example, to get
more information on the metering values available via the front-panel {METER}
pushbutton, refer to the MET Command (Metering Data) on page 10.20.
Some of the front-panel primary functions do not have serial port command
equivalents. These are discussed in Functions Unique to the Front-Panel
Interface on page 11.6.
