USING THE OPERATOR PANEL

When the IQ 300 is first powered on, the Operator Panel screen displays a brief
initialization message identifying the product and version. The screen then displays
the System Power screen. (At this point, pressing the Scroll arrows will display
system data as described in section 4.6 System Data Display Mode.)
Press the Menu button to proceed. The menu options are shown one at a time,
starting with Phase Data, see figure 4.2. Press the scroll up or down arrows to step
through all the main menu options. The presence of additional items is indicated by
the up and down triangles at the bottom right edge of the screen.
Keep in mind that the values displayed under several menu items depend on which
unit you are using and whether the system being monitored is 3 or 4 wire, and
require that the appropriate configuration be selected under the Edit Setpoints
menu. Menu descriptions cover both 3 and 4 wire systems where appropriate.
Note: The lagging or leading indicator and any signs may be the opposite of that
shown in the sample screens.
