If data exchange is lost at any time, the following screen will be displayed. The first red dot corresponds to the
stage at which the error occurred, and subsequent stages will indicate a red dot because the communication
sequence halted before this point.
The screen will state running or stopped, depending on how the user has set up the fail-safe function within the
PROFIBUS GSD file (see
"15.2.8 PROFIBUS GSD file" on page 153
). The
MODE
button gives access to the PROFIBUS
settings and the station address. When menus are accessed the pump continues to run in PROFIBUS mode.
If the
MODE
or
MENU
button has been pressed, after five minutes of inactivity the pump will revert to the home
screen and discard any unsaved changes, if there are still no communications then the BUS ERROR screen will be
displayed.
