System Status Flag Values
The lower-left corner of the Operate Methods screen displays a system status flag. This
flag is similar to the screen keys except that it appears in reverse video. The flag assumes
one of the statuses listed in Table 7-2.
7.3.2 Downloading Operating Parameters
When you press the Operate Method function key to display the Operate Methods screen,
the controller automatically downloads to the PowerLine modules the parameters that you
programmed on the Setup screens (see Chapter 4, Setting PowerLine Controller Operating
Parameters).
As the controller sends the parameter values to the modules, the system status is Setup.
When parameter loading completes, the status changes to
Initial, and the Start Run
screen key appears.
Resume Allows the run-time clock to continue after the Hold or
Stop Flow keys have been pressed.
Alarm Cancel Appears when you press More. Cancels the alarm.
